Work done = Potential Energy = (mg)h
mg = weight of the ball
= 1000 N * 2.5 m = 2500 Joules.
The work done during the 5 second is 2500 Joules.
Answer:
K = 316.66 N/m
Explanation:
Given that
F= 19 N
Displacement .x= 0.06 m
We know that spring force F given as
F = force
K = Spring constant
x = Displacement
Now by putting the values in the above equation
K = 316.66 N/m
Therefore the value of spring constant will be 316.66 N/m.
You can solve for acceleration by using the equation a=d/t
The third option (a=d/t) is correct because it is the only formula that solves for a, which stands for acceleration.
Hope this helped!
Explanation:
Given that,
Magnitude of electric field in +x direction, E = 4.9 V/m
Part A :
The relation between electric and magnetic field is given by :
c is the speed of light
So, the magnetic field of the wave at this same point in space and instant in time is .\
Part B :
The direction of electric and magnetic field is same i.e. +x direction.
Hence, this is the required solution.
C.) A thunderstorm
