Answer:
Explanation:
The simplest circuit has the battery in series with the resistor
V = IR
I = V/R = 1.5 / 15 = 0.10 Amps
It could be 1.5 / 150 = 0.01 A depending on how one assumes an error or not in "150hm"
Answer:
Car has more power output than crane
Explanation:
We have given that mass of the crane m = 1000 kg
Height through which crane lift the steel beam h = 10 m
Acceleration due to gravity
So work done by crane
Time period is given as t = 5 sec
We know that power
Now mass of the car = 1000 kg
Initial velocity u = 0 m /sec
Final velocity v = 10 m/sec
We know that work done is equal to the change in kinetic energy
So work done
Time ids given as t = 2 sec
So power
So car has more power output than crane
A microwave has more energy than radio but less than visible light
The distance from the sun to Neptune is about the same as the distance from Neptune to the next closest star, Proxima Centauri
This is false, materials that are poor conductors must be good insulators.
