it is required that an object weighing 8N be moved up ward at an acceleration of 2m/s what is the upward force needed ​

Answers

Answer:

F = 1.6 N

Explanation:

Newton's Second Law of Motion states that whenever an unbalanced force is applied on a body. It produces an acceleration in the body, in its own direction. The magnitude of the force is given by the following formula:

F = ma

where,

F = Force Required to Move the Object Upward = ?

m = mass of object

a = upward acceleration = 2 m/s²

but, we know that weight of object is given as:

Weight = mg

8 N = m(9.8 m/s²)

m = 0.8 kg

using values in the equation:

F = (0.8 kg)(2 m/s²)

F = 1.6 N

How does deploying slats or slots on an airfoil affect CL max and Stall AOA?
a) Stall AOA increases, CL max increases.
b) Stall AOA decreases, CL max increases.
c) Stall AOA increases, CL max decreases.
d) Stall AOA decreases, CL max decreases.

Answers

Answer: a. Stall AOA increases, CL max increases.

Explanation:

Deploying slats or slots on an airfoil affect CL max and Stall AOA by increasing Stall AOA and also increasing CL max.

It should be noted that the coefficient of lift CL would rise through the use of slots due to increase in boundary later energy. The slots also leads to delay of stall by through increase in AOA.

What is the speed of an object that travels 20 meters in 4 seconds?

Answers

Given:-

Distance covered by the particle (s) = 20 mTime taken (t) = 4 seconds

To Find: Speed of it.

We know,

v = s/t

where,

v = Speed,s = Distance &t = Time taken.

Putting the values,

v = (20 m)/(4 s)

→ v = 5 m/s (Ans.)

The speed of an object will be "5 m/s".

The given values are:

Distance,

d = 20 m

Time,

t = 4 seconds

As we know, the formula:

→ [tex]Distance (d)= Speed (v)\times Time (t)[/tex]

or,

→ [tex]Speed (v) = \frac{Distance (d)}{Time (t)}[/tex]

By putting the values, we get

→                [tex]= \frac{20}{4}[/tex]

→                [tex]= 5 \ m/s[/tex]

Thus the above answer is correct.

How much work must be done to stop a 1150 kg car traveling at 120 km/h?

Answers

Answer:

The work to be done is 638,761.12 J

Explanation:

Given;

mass of the car, m = 1150 kg

velocity of the car, v = 120 km/h = 33.33 m/s

Apply work energy theorem;

W = K.E

where;

W is the work done

K.E is the kinetic energy

W = ¹/₂mv²

W =  ¹/₂ (1150)(33.33)²

W = 638,761.12 J

Therefore, the work to be done is 638,761.12 J

True........................

The statement "thermal energy can increase even if the average kinetic energy is constant" is definitely true.

What do you mean by Kinetic energy?

Kinetic energy may be characterized as a type of energy that an object possesses due to its motion. It is defined as the work that is required to accelerate a body of a given mass from rest to its stated velocity. It measures the work an object can do by the virtue of its motion.

The thermal energy will still enhance even if the average kinetic energy remains constant. This is because it is based on the relationship between kinetic energy and thermal energy. Kinetic energy is defined as the energy possessed by an object or body as a result of its motion.

Therefore, the statement "thermal energy can increase even if the average kinetic energy is constant" is definitely true.

The mass of a string is 20 g and it has a length of 3.2 m. Assuming that the tension in the string is 2.5 N, what will be the wavelength of a travelling wave that is created by a sinusoidal excitation of this string with a frequency of 20 Hz. Provide the wavelength in units of m. Please note: You do not include the units in your answer. Just write in the number.

Answers

Answer:

The wavelength of the wave is 1 m

Explanation:

Given;

mass of the string, m = 20 g = 0.02 kg

length of the string, L = 3.2 m

tension on the string, T = 2.5 N

the frequency of the wave, f = 20 Hz

The velocity of the wave is given by;

[tex]v = \sqrt\frac{T}{\mu} {}[/tex]

where;

μ is mass per unit length = 0.02 kg / 3.2 m

μ = 6.25 x 10⁻³ kg/m

[tex]v = \sqrt{\frac{T}{\mu} } \\\\v = \sqrt{\frac{2.5}{6.25*10^{-3}} } \\\\v = 20 \ m/s[/tex]

The wavelength of the wave is given by;

λ = v / f

λ = (20 m/s )/ (20 Hz)

λ = 1 m

Therefore, the wavelength of the wave is 1 m

A. 798lbs
B. 421lbs
C. 1404lbs
D. 803lb

Answers

Answer:

D. 803 lbs

Explanation:

In order to find the compressive stress on all three blocks we first need to find the normal surface area of each:

Surface Area of 1 Block = 3.5 x 3.5

Surface Area of 1 Block = 12.25

Surface Area of all 3 Blocks = A = 3 x 12.25

Area = 36.75

Now, the stress is given by the following formula:

Stress = Force/Area

Stress = 29500 lbs/36.75

Stress = 802.72 lbs

Hence, the correct option will be:

D. 803 lbs

You have a stock bottle of 3mM tetrodotoxin solution, but your protocol states that
you need 6ml of 1mM tetrodotoxin (MW=319.27 g/mol). How much of your 3mM
stock solution (liquid) should you use to make the 1mM solution?

Answers

Answer:

Explanation:

Hello,

In this case, considering this as a dilution problem, the first step here is to consider that the moles of tetrodotoxin remains the same and just the volumes and concentrations are modified from the initial stock (1) and the required dilution (2):

[tex]V_1M_1=V_2M_2[/tex]

Whereas V is referred to volume and M to molar concentration, in this case in mM. In such a way, solving the V1 as the volume of the 3-mM solution we obtain:

[tex]V_1=\frac{V_2M_2}{M_1} \\\\V_1=\frac{6mL*1mM}{3mM} \\\\V_1=2mL[/tex]

It means you need 2 mL of the 3-mM solution.

If you go 45 meters at a speed of 16 m/s, how long does the movement take? Exact answer, do NOT round.

Answers

Answer:

2 seconds

Explanation:

The time taken for the movement is 2.81 seconds.

To find the time, the given values are,

Distance = 45 meters

speed = 16 m/s.

What is distance?Distance is the total movement of an object without any regard to direction.Distance can be evaluated how much an object moves from starting point to the end point.The distance completely depends upon the speed and time, i,e., the object covering some area with some particular time interval with the particular speed.Distance will be measured in meter, kilometer, etc..Distance is a Scalar quantity.

Formula of distance,

              Distance = Speed × Time.

As we have to find the time, Formula can be rearranged as,

              Time = Distance / Speed

Substituting the given datas in the formula,

Time = 45 / 16

        = 2.81 seconds.

So, the time taken for the movement is 2.81 seconds.

Answers

Answer:

Perpendicular to the polarization

Explanation:

In this question, we are interested in selecting the option that best complete the question.

The direction of propagation of light is perpendicular to the polarization. Polarized and unpolarized light behave in different manners.

In unpolarized light, the oscillation of the magnetic and electric occurs in all directions to the propagated light.

However, in the case of polarized light, there is a restriction of the electric field oscillation. And thus, it only oscillates in a direction which is perpendicular to the propagation light

Answer:

  3.0 m/s

Explanation:

The equation of motion for constant acceleration (a) is ...

  [tex]x(t)=\dfrac{1}{2}at^2 +v_0t+x_0[/tex]

The problem statement tells us v₀ = 1, and we read from the graph that x₀=1. We also read from the graph that x(10) = 21. Filling these values into the equation, we can find a and x'(10).

  [tex]21 = \dfrac{1}{2}a(10^2)+1(10)+1\\\\10=50a\qquad\text{subtract 11}\\\\a=\dfrac{1}{5}\\\\x'(t)=at+v_0\\\\x'(10)=\dfrac{1}{5}\cdot 10+1=3.0[/tex]

The final velocity of the object at t=10 s is about 3.0 m/s.

I couldn't wait to sit with her on the porch and listen to her tell old family stories. Every summer, my parents, my younger brother and sisters, and I drove down to the farm from our apartment in Baltimore. Aunts, uncles, and cousins from other parts of the country joined us there. We all came to spend time together, share memories, and celebrate Grandma Rose's birthday.I was named Caroline Rose after my Grandma Rose because we shared the same birthday. Grandma Rose referred to us as the "birthday gals," and we had our photograph taken together every year. This year, I was turning 15 and Grandma Rose was turning 84. In addition to having the same name and birthday, we shared other traits as well. "Caroline Rose, you're just as strong-willed as your Grandma Rose," Mama used to say to me in exasperation. I loved Grandma Rose and I wanted to be like her, so I didn't mind.Daddy called the 12-hour drive to the farm "our pilgrimage," because it was a journey we made every summer to a place we held sacred. Our preparations felt just as sacred as our destination. The morning before the trip, my younger siblings and I pulled open closets and dresser drawers searching for shorts, bathing suits, and matching flip flops, which we packed in garbage bags. "Easier to fit a bunch of squishy garbage bags in the car than four bulky suitcases," Mama reasoned.In the late afternoon we ate a supper of odds and endswhatever was in the fridge that needed to be eaten before we left for two weeks: cold ham and macaroni salad, peanut butter and jelly on toast, scrambled eggs and bacon. It was always a surprise to see what Mama came up with for our pre-trip dinner.Before an extra early bedtime, we fixed up the car so my brother and sisters and I would be comfortable during the long drive. We spread quilts on the seats and packed novels, coloring books, comic books, chewing gum, playing cards, and craft projects to keep ourselves busy. Then we went to bed with our clothes on. When our parents woke us up at three a.m., we shuffled into the car with our bed pillows and fell back asleep as Daddy began the long drive south.Twelve hours later, we pulled up in front of Grandma Rose's old white house and burst out of the car. Many relatives had already arrived. Aunts and uncles squeezed the children, but we cousins greeted each other shyly.It was my private custom to walk through the house and make sure everything was just as I remembered itsame pictures of birds and flowers hanging on the dining room wall, same green-and-yellow striped armchairs in the living room, same squeaky screened door leading out to the porch. In the kitchen, I'd stop to breathe in the house's familiar smells. Being back in this house made me feel like a long-lost book that had finally been returned to its owner and put back on the shelf where it belonged.For the cousins, the annual visit was a way of measuring our growth, both physical and emotional. How much taller were we this summer? Which barn shelf could we reach? What would we be allowed to do this summer, now that we were a year older? The group of older cousins, which included me, talked about who had boyfriends or girlfriends. Last year, I'd turned bright red when this topic came up. This summer I did too, but now I had my boyfriend, Cash, to talk about.I didn't realize then that the grown-ups were measuring themselves, too, but they used different standards: Who had new babies, grandbabies, or children starting high school or college? Who was ready to retire? How bad was the arthritis?After dinner that first night, Grandma Rose and I sat down together on the porch to look through our birthday bookthe little book that held our birthday photos. There were plenty of empty pages, and I wanted Grandma Rose and me to fill them up with years and years of birthday pictures. It was another kind of measuring stick.Grandma Rose and I sat quietly for a while, just the two of us, just as I'd hoped we would. I was so grateful to be back on the farma place full of people I'd known and loved my whole life, with Grandma Rose at the center of our family universe.Read the central idea from "A Home Away from Home."Going to Grandma Rose's farm was a special tradition for the author and her family.How does the author develop this central idea over the course of the memoir?Select the two correct answers.by describing the ways the cousins seemed different each summer on the farmby describing the trip as a pilgrimage, or an annual journey to a sacred placeby explaining that both the cousins and the grown-ups changed over the yearby explaining that the family's preparations for the trip were also important Choose the verb tense that makes the most sense.
