Answer:
Hey
Your answer would be:
stationary objects within the field will move when realesed.
The reason why is because fields store potential energy as you know. when something is stationary it has potential, but when it is released that potential energy turns into kinetic energy.
this made me think of a funny joke:
A man was about to jump off of the Empire State Building when a physicist from below yield, Wait don't! you have so much potential!
lol always cracks me up.
Answer:
speed of light in miles per hour will be
Explanation:
We have given speed of the light
We have to change this velocity in miles/hour
It is given that 1 miles = 1610 m
And we know that 1 min = 60 sec
And 1 hour = 60 minute
So 1 hour = 60×60 = 3600 sec
Here
And 1 sec
So
So speed of light in miles per hour will be
It’s because flourecent lights operate at higher temperatures than incadecent lights.
Answer:
Power = 2940 Watts
Explanation:
Given the following data;
Mass = 60 kg
Height = 300 meters
Time = 1 minutes = 60 seconds
To find the power;
First of all, we would determine the potential energy possessed by the person due to height.
We know that acceleration due to gravity is equal to 9.8 m/s².
Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
Where,
P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Substituting into the formula, we have;
P.E = 60 * 9.8 * 300
P.E = 176400
Next, we find the power using the following formula;
Power = energy/time
Power = 176400/60
Power = 2940 Watts
It's inertia. A rule that you see every day, for example a brick will stay in the same spot unless a force acts on it.
