Answer:
The velocity of the ball at it's highest point is zero.
Explanation:
When we toss a ball upwards as we know that it's motion is an uniformly accelerated motion with acceleration = 
in the downward direction.
Hence as we throw the ball upwards it's speed will go on decreasing as it gains height. The ball will stop gaining height when it's velocity becomes zero and the ball starts to descend again towards earth.
If the ball is tossed at an angle with the horizontal in that case it's velocity at the top most point will not be zero but in our case since the ball is tossed vertically it's velocity at the topmost point will become zero.
C) Natural and Artificial sources
Answer:
Explanation:
given,
radius of the sphere, R = 54.5 cm
R = 0.545 m
Electric magnitude of the conductor,E = 4 x 10⁵ V/m
Electric potential just outside of the surface,V = ?
we know,
Hence, the Potential just outside the surface is equal to
Answer:
Target Behavior would be the behavior known to be changed, it can be defined by function or topography
Answer:
Work done, W = 8 J
Explanation:
We have,
Force acting on the cart is 4 N
Cart covers a distance of 2 m
We need to find the work done by the cart. Work done by an object is given in terms of force and displacement. It can be given by :
So, the work done by the cart is 8 J.
