7. Mrs. Everhart developed the theory that all bulldogs are great pets. After all her bulldog Meatball is a
wonderful dog! Is this statement a scientific theory? Why or why not.
finoccientific method

Answers

Answer 1

Answer: No.

Explanation:

A scientific theory is an explanation of some aspect of the natural world that can be tested several times, and follows the scientific method. And, when possible, theories are tested with experiments.

Now, a scientific theory must meet some criteria, and one of those is that it must be supported by several (and independent) strands of evidence.

In this case, we have only one, Meatball, and it is not enough, then it can not be a scientific theory.

PLEASE HELP WILL NAME BRAINLIEST!! An object is dropped from rest. What is its instantaneous speed when it has been in motion for 4 s? The acceleration of gravity is 9.8 m/s^2 Answer in units of m/s.

Answers

Explanation:

Using kinematics,

t = 4s

u = 0m/s

a = 9.8m/s^2

Therefore v = u + at = 0 + (4)(9.8) = 39.2m/s.

The skid marks left by the decelerating jet-powered car The Spirit of America were 9.60 km long. If the car's acceleration was -2.00 m/s2, what was the car's initial velocity.

Answers

Answer:

The car's initial velocity is 195.96 m/s

Explanation:

Given;

the length of the mark, x = 9.6 km = 9600 m

acceleration of the car, a = -2 m/s²

Apply the kinematic equation below

v² = u² + 2ax

where;

v is the final velocity = 0

u is the initial velocity

simplify the equation and you will obtain;

0 = u² + 2ax

0 = u² + 2(-2)(9600)

0 = u² - 38400

u² = 38400

u = √38400

u = 195.96 m/s

Therefore, the car's initial velocity is 195.96 m/s

A 25.0-mL aliquot of an aqueous quinine solution was diluted to 50.0 mL and found to have an absorbance of 0.656 at 348 nm when measured in a 2.50-cm cell.A second 25.0-mL aliquot was mixed with 10.00 mL of a solution containing 25.7 ppm of quinine; after dilution to 50.0 mL, this solution had an absorbance of 0.976 (2.50-cm cell). Calculate the concentration of quinine in parts per million in the sample.

Answers

Answer:

The  value  is  [tex]C =  21.07 ppm[/tex]

Explanation:

From the question we are told that

 The volume of the first  aliquot is [tex]V_a1  =  25.0 \  mL[/tex]

 The  volume after dilution is  [tex]V_A =  50.0mL[/tex]

 The  Absorbance of the first solution  is  [tex]A_1 =  0.656[/tex]

 The  wavelength at which the absorbance occurred is   [tex]\lambda _1 =  348 nm  =  348*10^{-9} \  m[/tex]

    The  length of the cell [tex]l  = 2.50 \  cm[/tex]

    The volume the second  aliquot is [tex]V_{a2}  =  25.0 \  mL[/tex]

     The  volume of the solution it was mixed with is  [tex]V_s  =  10.00mL[/tex]

     The  concentration of quinine in the 10 mL solution  [tex]Z =  25.7ppm[/tex]

    The volume of the second solution after dilution is [tex]V_d = 50.0 mL[/tex]

      The  absorbance of the second solution is [tex]A_2 =  0.976[/tex]

Generally the concentration of quinine is mathematically represented as

         [tex]C =  \frac{A_1 *Z *  V_s  }{(A_2 -A_1) V_{a2}}[/tex]

=>    [tex]C =  \frac{ 0.656  *  25.7 *  10.0}{ (0.976 -  0.656) *  25}[/tex]

=>   [tex]C =  21.07 ppm[/tex]

If a NASCAR driver is driving around a track, and he travels 600 miles in 3 hours, what is his average speed in miles per hour (mph)? __________ mph

Answers

Answer:

200 mph.

Explanation:

If a NASCAR driver travels 600 miles in 3 hours, the way to calculate the speed at which the car is driving comes from dividing the distance factor by the time factor.

Thus, we must divide 600 by 3 (600/3), which gives 200 as result. Thus, if in 3 hours he travels 600 miles, in one hour he will travel 200 miles, which means that his average speed is 200 mph.

A car goes from 40 m/s to 30 m/s in 5 sec. What is its acceleration?

The electrostatic force that a charged particle, q1q1 , exerts on another charged particle, QQ , at a distance r1r1 , is FF . A second charged particle, q2q2 , exerts the same force FF on QQ at half the distance r1r1 . What is the value of q1q1 in relation to q2q2 ?

Answers

Answer:

q₁ / q₂ = 4

Explanation:

In this exercise we must use Coulomb's law

         F = k q₁q₂ / r²

For this case the electric force is

        F = k q₁ Q / r₁²

indicate that another particle q₂ has the same force on Q, but for r₂ = r₁ /2

        F = k q₂ Q / r₂²

we equate the two equations

           q₁Q / r₁² = q₂ Q / r₂²

we substitute r₂

        q₁Q / r₁² = q₂ Q / (r₁/2)²

        q₁ = q₂ 4

the relationship between the two charges is

         q₁ / q₂ = 4

a cart rolls down a track. it starts from rest and attains a speed of 2.7 m/s in 3 s, what is the acceleration and distance traveled?

Answers

Answer:

Acceleration and the distance traveled are 0.9 m/s² and 4.05 m

Explanation:

Given that,

Initail speed, u = 0

Final speed, v = 2.7 m/s

Time, t = 3 s

To find,

The acceleration and distance traveled.

Solution,

Acceleration is change in speed per unit time

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{2.7-0}{3}\\\\a=0.9\ m/s^2[/tex]

Let s is the distance,

[tex]d=ut+\dfrac{1}{2}at^2\\\\\because u=0\\\\d=0+\dfrac{1}{2}\times 0.9\times 3^2\\\\d=4.05\ m[/tex]

So, acceleration and the distance traveled are 0.9 m/s² and 4.05 m

2. How long will it take for a ball thrown vertically upward with an initial velocity of
480 km/h to reach its maximum height?

Answers

Answer:

13.33 seconds

Explanation:

At maximum height, the equation of motion becomes:

v = u + at

Since the object was thrown vertically, the initial velocity (u) is zero and the acceleration (a) becomes the acceleration due to gravity (10 m/s2). The equation becomes:

v = at

v = 480 km/hr = 133.333 m/s

    10t = 133.333

       t = 133.333/10

           t = 13.33 seconds.

The time for the ball thrown vertically with a velocity of 480 km/hr to reach the maximum height is 13.33 seconds.

difference between universal law of gravitation and acceleration due to gravity​

Answers

Explanation:

The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G(capital g). The relation between G and g is not proportional. That means they are independent entities.

G and g

In physics, G and g can be related mathematically as –

\(g=\frac{GM}{R^{2}}\)

Where,

1=g is the acceleration due to the gravity of any massive body measured in m/s2.

2=G is the universal gravitational constant measured in Nm2/kg2.

3=R is the radius of the massive body measured in km.

4=M is the mass of the massive body measured in Kg.

Answers

Answer:

The object moves 6 m in every second.

Explanation:

When we say something is constant, we simply means that it does not change with time i.e it the same through out irrespective of time.

Now, let us answer the question given above.

An object moving at a constant speed of 6 m/s. Has the following characteristics:

1. The object moves 6 m in every second.

2. The object is not accelerating since it has a constant speed. Therefore, the acceleration of the object is zero.

3. The object is moving as it covers a distance of 6 m in every second.

4. The speed remains the same since the speed of object is constant.

Thus, the right answer to question is: The object moves 6 m in every second.

No, work wasn't done​

Answers

Answer:

Explanation:

You may have not seen a good outcome but you did put effort in.

When a force is applied on the car and it doesn't move then it simply means

work wasn't done.

The formula for work is given below:

Work = Force ₓ Displacement

For work to have been done , the applied force must cause the object to

change its position(displacement).

In situations where the force applied doesn't cause a change in position then work can't be calculated. This means no work was done on the car despite the applied force causing him to be tired.

All investigations share steps of the scientific method, such as asking a question, conducting research, or analyzing data. The differences between investigations are usually related to what's being examined and the order of the steps followed.

In a criminal investigation, facts are collected about a crime that has already happened. While there are individual tests that can be done on certain types of evidence, there isn't an experiment to test every part of a crime. It can also be difficult to control all factors in a crime scene in order to test one variable at a time. Usually, there are so many variables and missing facts in a crime that a hypothesis and conclusion are hard to determine.
