Answer:4 times
Explanation:
Given
Balls are identical and thrown with initial velocity lets say u and 2u because the other ball is thrown with twice the velocity of first
Maximum height reached by first ball is h which is given by
For second ball
Thus height gained by second ball will be 4 times of first ball.
Answer:
a. 3.039cm
b.magnetic field is
Explanation:
Direction of the solenoid magnetic field is along the axis of the solenoid. and magnetic field due to the wire perpendicular to that due to the solenoid.. Magnetic field at r is given by:
Angle of net magnetic field from axial direction is given by:
,
Field due to solenoid:
Field due to wire:
Therefore, r:
Hence, the radial distance is 3.039cm
b.The magnetic field strength is given by:
Hence, the magnetic field is
D.) Asteroids
Asteroids are large rocks that orbit the sun. They aren't considered planets since they are smaller.
Time to complete one circular revolution is know as time period
it is given by formula
here
now time to complete the revolution is given by above formula
So this will complete one revolution in 4.13 s
