We know that an object floats in a fluid if the density of the object is less than the density of the fluid. When some air or water is heated, it expands. That makes its density less than cooler air or water, so it floats in them.
Atomic mass can change through the process of fusion. Another way is, it can also change in nuclear fusion.
Answer:
Explanation:
Given
Initial Velocity (u)=13 m/s
angle
distance between fence and deer=2.5 m
We consider deer jump similar to projectile motion
equation of trajectory
Thus deer will cross the fence with an difference in its jump and fence
1.5-1.148=0.351 m
so deer rises during when it is over fence
No, sound waves are invisible to our eyes
