Answer: The velocity of the ball is 30.0 m/s
This can be calculated by using the value of acceleration as 10.0 m/s2 in free fall and the given time of 3.0 seconds. To get the
velocity, one will have to multiply the acceleration with the given time and the
quotient would result to 30.0 m/s. Mostly all object regardless of their mass,
fall to earth with the same acceleration in the absence of air resistance and as
the child drops the ball from a window, it gains speed as it falls.
lovely question hope 7 solve it

Answer:

Explanation:
First of all, we need to find the pressure exerted on the sphere, which is given by:

where
is the atmospheric pressure
is the water density
is the gravitational acceleration
is the depth
Substituting,

The radius of the sphere is r = d/2= 1.1 m/2= 0.55 m
So the total area of the sphere is

And so, the inward force exerted on it is

the answer to your question is 15 :)

Given that Force affects the body and results in different changes.
The grid that has the words related to the effects of force are :
a) Force could be a push or a pull.
c) Force has magnitude as well as direction.
e) Force acting on an object may cause a change in its state of motion or a change in its shape.
f) A force can act on an object with or without being in contact with it.
