Answer:
14 cm
Explanation:
F = (frac{uv}{u – v})
F = +ve
v = -ve
30 = (frac {25 {times} (-v)}{25 – (-v)})
v = (frac {25 {times} (-v)}{25+v})
v = 14cm
(Note that either negative or positive values go to show the positioning and hence, they are not a strong necessity in your final answer.)

Answer:
All the planets orbit the Sun in nearly the same plane.
<u>Answer:</u>
The correct answer option is momentum.
<u>Explanation:</u>
Momentum is the product of an object's mass and velocity.
It is a term which describes the relationship between the mass of an object and the velocity of an object.
Momentum can be represented in the form of an equation as:
P = mv
where P is the momentum,
m is the mass of the object; and v is the velocity of that object.
Answer:
The speed of the wave with a frequency 100 mhz will be 
Explanation:
We have given that frequency of light is 100 mhz
We have to find the speed of light in vaccuum
We know that all electromagnetic waves travels in vaccum wth the same speed as the speed of light
And we know that speed of light is equal to
So the speed of the wave with a frequency 100 mhz will be
