Answer:
Explanation:
Given
height of building h=3 m
Landing velocity of diver
at an angle of 
Let u be the initial velocity of diver at an angle of \theta with horizontal
Since there is no acceleration in horizontal direction therefore horizontal component of velocity will remain same
---- -----1
Considering Vertical motion

here 




----------------2
Divide 2 and 1 we get



Thus 

Answer:
Speed is a "scalar" quantity
(C) is the correct answer
An object could travel at 10 m/s to some point and then return to the origin at 10 m/s for an average speed of 10 m/s, however it's displacement over that time would be zero for a net velocity of zero.
Newton's 2nd law of motion: Force = (mass) x (acceleration)
If you want to move a 7-kg object with an acceleration of 6 m/s²,
then you will need to push it with (7 x 6) = 42 newtons of force.
You don't mean the force of an object.
Answer:
C) U-235
Explanation:
On Isotope stability, an isotrope will be least stable when Proton and newtron are both odd.
