A bomber plane moves horizontally with a speed of 500 m/s and a bomb released from it, strikes the ground in 10 sec. angle at which it strikes the ground will be (g=10m/s)1. tan-1 (1/5)2. tan-1 (1/2)3. tan-1 (1)4. tan-1 (5) Ans) the bomb is dropped , therefore its horizontal velocity = 500
and vertical velocity = 0
in 10 sec
v = u + at
= 0 + 10x10
= 100 m/s
horizontal velocity remains unchanged bcoz there''s no accn in the horizontal
therefore
tan Θ = ( vertical velocity )/ (horizontal velocity ) = 1/5
An atom in a solid state has no degrees of freedom for transnational and rotational speed. At great temperatures due to vibration along 3 axes it has 3 Χ2(directions) = 6 degrees

Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
Red light (λ = 685 nm) falls on a slit that is 0.025 mm wide. The distance between the centers of the central bright band and the second-order dark band is 6.3 cm. What is
the numerical ratio of displacement to the distance covered is always ???????????????
