Answer:the velocity is zero, the acceleration is directed downward, and the force of gravity acting on the ball is directed downward.
Explanation:
When a ball is tossed vertically upwards, it reaches its maximum point. This maximum point is known as the maximum height of the ball. At this maximum height, its velocity is zero, its acceleration is directed downwards and the force of gravity acting in the ball is directed downwards towards the earth.
Answer:
They both are part of electromagnetic radiation.
Radio waves have longer wavelength than visible waves.
Radio waves have lower frequency than visible waves.
Explanation:
Rate of change of velocity is called acceleration. When this rate of change is constant, it is called uniform acceleration. Like the change of velocity of an object falling freely under gravity. Its velocity increases by 9.8 m every second. This acceleration is denoted as 9.8m/s^2
Answer:
B1 = μ_o•I1/2πr
Explanation:
According to the right hand rule, we can say that the magnetic field at the second wire due to the current being carried in first wire is given by;
B1 = μ_o•I1/2πr
Where;
r is distance that separates the two wires
μ_o is a constant known as permeability of free space
I1 is current in wire 1
Answer:
EMF = 108.3 Volts
Explanation:
As per Faraday's law of electromagnetic induction we know that rate of change in magnetic flux will induce EMF in closed loop
So it is given as


now we know that
N = 50 turns
B = 1.5 T
A = 0.325 m^2

now we have
