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

What two factors will make an object stable ​
galben [10]

The position of the centre of gravity of an object affects its stability. The lower the centre of gravity (G) is, the more stable the object. The higher it is the more likely the object is to topple over if it is pushed. Racing cars have really low centres of gravity so that they can corner rapidly without turning over.

Increasing the area of the base will also increase the stability of an object, the bigger the area the more stable the object. Rugby players will stand with their feet well apart if they are standing and expect to be tackled.
