Answer:
the vertical distance between the two object will increase uniformly when they are dropped after a fixed interval of time
Explanation:
Since airplane is moving horizontally with constant speed v
so when object is dropped from the plane then the speed of the object will be same as that of the speed of the airplane
so we can say that two object when dropped after some interval of time then they always lie in same vertical line
now we know that they both have same acceleration in vertical line so the motion of two objects relative to each other in vertical direction is always uniform motion because they have no acceleration with respect to each other
So the vertical distance between the two object will increase uniformly when they are dropped after a fixed interval of time
Answer:
Explanation:
Given:
- gravitational field strength of moon at a distance R from its center,

- Distance of the satellite from the center of the moon,

<u>Now as we know that the value of gravity of any heavenly body is at height h is given as:</u>

∴The gravitational field strength will become one-fourth of what it is at the surface of the moon.
If it is a multiple choice question is C. Infrared waves do not carry enough energy to kill cancerous cells.
His average speed is (35m/45s) = 7/9 meters per second.
His average velocity is (30m W + 5m E) / (45s) = 25 m/s West .
