Answer:
C. Potential energy is related to an object's position, and kinetic
Explanation:
The energy contained in the small motions of the object's molecules can be broken up into a combination of microscopic kinetic energy and potential energy.
Answer:
Part a)
Part b)
Ball thrown downwards =
Ball thrown upwards =
Part c)
Explanation:
Part a)
Since both the balls are projected with same speed in opposite directions
So here the time difference is the time for which the ball projected upward will move up and come back at the same point of projection
Afterwards the motion will be same as the first ball which is projected downwards
so here the time difference is given as
Part b)
Since the displacement in y direction for two balls is same as well as the the initial speed is also same so final speed is also same for both the balls
so it is given as
Part c)
Relative speed of two balls is given as
now the distance between two balls in 0.8 s is given as
Simple the ozone layer is the layer in the atmosphere that protect us from the harmful rays the sun produces and without the ozone layer things will get catostrophic if you dont live in the ocean or a cave
The temperature of the air above it
Answer
given,
mass of the solid door = 22 Kg
dimension of door = 220 cm x 91 cm
moment of inertia about the hinge
r is the distance from the one edge which is equal to 91 cm or 0.91 m
Moment of inertia about center for rectangular gate is equal to
moment of inertia for rotation about a vertical axis inside the door, 15 cm from one edge
