Answer:
16 mm with 14 mm inside diameter.
The magnitude of the average force exerted on the ball by the wall is calculated below.
The average force exerted by the ball on the wall is 3 N
Explanation:
Given:
mass of the ball (m)=0.10 kg
speed (v) =3.0 m/s
time taken(t) =0.01 seconds
To calculate:
Average force(F) exerted by ball on the wall
We know;
F=(m×v)÷t
F=(0.10×3.0)÷0.01
<u><em>F=3 N</em></u>
Therefore the average force exerted by the ball on the wall is 3 N
The correct answer for above statement is:
A. Heat energy is released by the substance.
Explanation:
The reverse of deposition is sublimation and therefore generally deposition is termed desublimation. One example of deposition is that the method by that, in sub-freezing air, water vapor changes on to ice while not initial changing into a liquid.It is a process of releasing energy.
Answer:
7.2 as used in the equation
Answer:
A) x4
Explanation:
Magnification is equal to image size divided by the actual size, or M = I/A.
The image size is the student's drawing, which is 28.8 cm, and the actual size is 7.2 cm. Divide them, and cancel out the units, and you should get:
28.8 cm/7.2 cm = 4
