The current through the heater is 8 A if potential difference is increased to 120 V.
Explanation:
- According to Ohm's Law, the potential difference (Voltage) is directly proportional to the current flowing through a conductor.
That is, V ∝ I
⇒ V = IR where R is the constant of proportionality called resistance.
- In this case, given voltage = 60 V and current = 4 A. To find the current, first find the constant of proportionality, resistance of the heater.
R = V/I = 60/4 = 15 ohm
- If the potential difference is increased to 120 V, find the current flowing through it.
I = V/R = 120/15 = 8 A
Answer:
C. It is converted into another form, mainly kinetic energy
Explanation:
Potential energy is energy available to be used in an object that isn't currently moving. When an object begins moving, potential energy becomes kinetic energy.
Answer:
1. A Spacecraft to Survive Deep Space
2. That includes food, clothing, mid-deck seats, flight tools, cameras, parachutes, safety equipment, sleep restraints and, most importantly, the astronaut spacesuits -- known as "extravehicular mobility units."
3. A new compact toilet, smaller than the one on the space station. ... suppression system or exercise equipment that helps astronauts stay in shape. New Spacecrafts
Explanation:
'Doing work' is a way of transferring energy from one object to another, energy is transferred when a force moves through a distance.
If i explain with formula
Work done (J) = Energy transferred (J)
So more energy, more work done bc u transferred more energy to move the object and doing the work. and if you only use a little of energy, the work done also only a little.
