Answer:

calculate the volume of each sample by subtracting the intial water volume from the volume after the sample was added . Record the volume of each sample on your chart in mililiters(ML).

Answer:

There is no particular relationship between the height and shoe size. But the shoe sizes in males is usually bigger than females. And the shoe size tends to get bigger when the person is taller.

Explanation:

Answer:

Like gases, the particles in plasmas are constantly moving at high speeds, and do not have a definite shape or volume. Plasma is formed when the kinetic energy of the molecules in a gas gets very large and the temperature gets very high. This causes electrons to be released by the atom, creating ionized particles, which are positive ions and negative electrons.

Explanation:

Sample Response <3.

Answer:

The correct answer is I just did the quiz

Force,F=144N

Mass,m=12Kg

Force=Mass*Acceleration

144=12*a

12a=144

a=12

Explanation:

Draw a free body diagram.  There are two forces: weight force pulling down and air resistance pushing up.

Sum the forces in the y direction:

∑F = 50 N − (30 kg) (10 m/s²)

∑F = -250 N

Answer: metre per second

The unit of speed is the metre per second, but the most common speed in everyday usage is the kilometre per hour in the US and the UK, miles per hour.

Answer:

B. I looked it up I hope it's right

Explanation:

i hope this helps.

Answer:

its obviously C

Explanation:

i smart like dat

Answer:

If they both start at the same height then most likely that means that each has an intical velocity  and a net force sooooo ball A 19.6

Explanation:

Answer: The mass of ball C is greater than the mass of ball A but less than the mass of ball B.

Answer:

Choice B) B There is no net force on the hockey puck.

Explanation:

In case when the hockey puck the slides with the same velocity or constant velocity so the force with respect to the hockey should contain that there is no net force as if the body moves along with the same velocity or the constant velocity so in this case the body acceleration is zero

And according to the newton second law i.e.

F = ma

In case when the acceleration is zero so the net force is zero

Therefore the option b is correct

Explanation:

Using Equations of Motion :

(1) v = u + at

24 = 6.5 + a * 210

a (Acceleration) = 0.083 m/s^2

(2) v^2 = u^2 + 2aS

S = 576 - 42.25 / 0.166

S (Distance travelled) = 3215.3 m

(Option A seems a typo since the answer is 3215.3 m)

Answer:

acceleration is 1.6 m/s^2

Explanation:

This is a question involving Kinematics so we can use one of the kinematic equations.

Given info: Vi= 2.6 m/s. Vf= 15.4 m/s. T= 8s

We need to solve for acceleration

The best equation to use is (Vf = Vi + at) as it contains all the info we need to solve for acceleration.

Now substitute the values given into the equation.

Vf = Vi + at >> 15.4 = 2.6 + a8

Now solve for a by rearranging the equation.

15.4 -2.6= 8a >> 12.8=8a >> 12.8/8= 8a/8 >> 1.6 =a

NOTES:

Acceleration is the rate of increase of velocity

Vf is final velocity or velocity after acceleration/de-accaeleration occurs

Vi is intial velocity or velocity before acceleration or de-accaeleration occurs

Time is time it took for a certain motion to occur.

Answer:

Rubbing his hand and ironing is Mechanical Energy being transformed into Thermal Energy.

Throwing a rock vertically in using Kinetic Energy, it then transforms into Gravitational Energy as the rock falls.

Explanation:

First, as Kwane rubbing his and and iron his clothes using the energy to create heat, that is thermal being transformed.

The rock being thrown uses kinetic energy and due to graviational force of the earth, it is being transformed into Potential Gravitational Energy.

Answer:

okay I might be wrong but it was an answer i had in like fifth grade MAYBE 1,200 meters

Explanation:

Answer:

No

Explanation:

There are many units that are used to measure length of an object. For example centimeters, meters, millimeters etc.

There is a relationship between any of two units to measure lengths. If we want to convert some length from cm to m, it can be done as follows :

1 cm = 0.01 m

or

1 m = 100 cm

When we use this conversion, the calculation remains the same. Only the way to represent it will be different.

Hence, there is no lose of information when converted from centimeters to meters.

Answer: Larger net forces are required to accelerate objects that have more mass

Explanation:

The answer is increase.

d = m/v. if you increase the mass without changing the volume, the density will increase.

Answer:

c

Explanation:

though c is wider it has more water.

The answer is *C* Because The C Jar is Wider than others so it holds more water

Explanation:

Just shift everything except r to the other side.

[tex]r = \sqrt{ \frac{3v}{\pi \: h} } [/tex]

Answer:

2.3 Nm clockwise

Explanation:

Take counterclockwise to be positive and clockwise to be negative.

∑τ = (3 N) (2.5 m) − (7 N) (1.4 m)

∑τ = 7.5 Nm − 9.8 Nm

∑τ = -2.3 Nm

The net torque is 2.3 Nm clockwise.

Answer:

Principal focus of concave lens -

★ The point at which rays parallel to principal axis coming from infinity appear to converge after being refracted from concave lens is called the principal focus of concave lens.

________________________

• Additional information -

★ Principal focus - A number of rays parallel to the principal axis after reflection from a concave mirror meet at a point on the principal axis or appear to come from a point after reflection from a convex mirror on the principal axis. This is called principal focus.

Answer: a straight line with a positive slope

Explanation:

If an object is moving and it changes its position by 2 units every 4 s starting from the origin,

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is meter/second.

Learn more about speed from here If an object is moving and it changes its position by 2 units every 4 s starting from the origin,

speed = distance /time

          = 2 units / 4 seconds

          = 0.5 units/seconds

Thus, the speed of the object would be 0.5 units /seconds

Answer:

The answer to your question is 404.2000

The water. Take the specific heat of steel, estimate the volume of the nail, you know the volume of the water, which has a specific heat of one. Or be obvious. If you dropped a red hot nail into a liter of cold water, what would happen?

Answer:

Water

☆One litre boiling water has more amount of heat because it has much more greater mass than iron nail

I am not sure if its wrong,sorry

but here is the iron nail explanation also

☆A red hot nail has more amount of heat because the density of iron is more than that of water

Answer:

a scientific law must be universally correct there could be no contradictions regarding the law anywhere

Answer:

use first equation of motion v=u+at..v is 0..since we have to take him to rest and u is 13.5

Explanation:

u = 13.5 m/s

a = - 2.5 m/s^2

v = u + at

0 = 13.5 - 2.5 * t

t (time to reach a complete halt) = 5.4 sec

Answer:

0 m/s²

Explanation:

Velocity is the slope of the position vs time graph.  The graph is linear, so the velocity is constant.  Since the velocity is constant, the acceleration is 0.

Answer: Sample Response: The root beer exerts a force on all sides of the ice cream. These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward. The ice cream floats because the buoyant force is greater than the weight of the ice cream.

Answer:

The average is 247.33 if it is for the whole number then it is 247

Explanation:

I did it by adding it all together and dividing it by 3

Answer:

247.33 is the average.

Explanation:

To find the average of a set of numbers:

a. add them up.

b. divide by how many numbers there are.

SO:

a. 255 + 242 + 245 = 742.

b. 742 (total) divided by 3 (# of numbers) = 742/3 = 247.33.

Hope this helps!
