Examples of devices that convert electrical energy into mechanical energy — in other words, devices that use electrical energy to move something — include:
the motor in today’s standard power drills
the motor in today’s standard power saws
the motor in an electric tooth brushes
the engine of an electric car
the motor in a fan
the motor in a remote control cars that runs on batteries. So your answer would be B. Motorsport
what are you trying to ask?
Let's see what variables we've got first. Hmmm. We have:
Displacement, d = 28 m
Time taken, t = 11 s
Initial velocity, u = 0 m/s (at rest)
And now we need to find the final velocity, v. Among the 4 (or 5) equations of motions, there's no equation that will let us simply plug in the values and give an answer sigh. But fear not! We'll do it in steps.
I'm going to pick one of the motion equation to find more information:
I know everything except for a in this one, so I I'll use this! After plugging in values, I get a = 0.4628 m/s^2.
Now I'm going to use another motion equation that has v in it because that needs to be solved!
Now I know everything except dial velocity v. Nice!
v = 0 + (0.4628)(11)
Answer:
so the answer is this because the answer is that
Explanation:
and the reason why the answer is this and that is because the answer is that
