Potential energy is directly related to the height of an object. Point 1 is higher than point 4, so the potential energy is greater at point 1.
I think it's mass...
The mass of an object refers to the amount of matter that is contained by the object; the weight of an object is the force of gravity acting upon that object. Mass is related to how much stuff is there and weight is related to the pull of the Earth (or any other planet) upon that stuff.
Answer:
320 N/m
Explanation:
F = k·Δx
where
F is the restoring force of the spring
k is the proportionality constant called the ‘spring constant’
Δx is the change in the spring’s position due to the deformation.
You need the k so
25 cm= 0.25m
k=F/∆x = 80/0.25 = 320 N/m
For this one, all you really need to do is eliminate any answers
that are absurd or meaningless.
You can't increase a transformer.
You can't increase a circuit.
You can't increase a generator.
When the <em><u>current</u></em> through a coil of wire increases, the magnetic field
around the coil increases, so there would be more magnetic force
between the coil and a permanent magnet.
