At a given depth a liquid exerts more pressure in downward direction, then in the upward direction.` "__________"`

Fluids at a given depth exert "______" pressure in all directions.

Gases exert pressure equally in all directions, Why ?

Different liquids exert the same pressure at a given depth.

Give reasons : Gases exert pressure in all directions.

Correct the statement : Gases do exert pressure in single direction.

Give reasons for the following: Gases exert pressure in all directions

Assertion: In a string wave, during reflection from fix boundary, the reflected wave is inverted. Reason: The force on string by clamp is in downward direction while string is pulling the clamp is upward direction.

More the density of a liquid, less the pressure it exerts. "__________"

A player throwsa a ball upwards with an initial speed of 29.4 ms^(-1) . (i) What is the direction of acceleration during the upwared motion of the ball? (ii) What are the velocity and acceleration of the ball at the highest point of its motion? (iii) Choose the x=0 and t=0 to be the location and time of the ball at its highest point, vertically downward direction to be the positive direction of X-axis, and give the signs of positive, velocity and acceleration of the ball during its upward, and downward motion. (iv) To what height does the ball rise and after how long does the ball return to the player's hand?( Take g =9.8 ms^(-2) , and neglect air resistance).

(A): Two similar trains are moving along the equatorial line with the same speed but in opposite direction. They will exert equal pressure on the rails. (R): In uniform circular motion the magnitude and direction of acceleration remains constant but the direction of motion continuously changes.
