Answer: A) chemical energy → kinetic energy→ heat energy

Explanation:

Energy neither forms nor gets destroyed. Energy gets converted from one form to another. Diesel is a fuel which has chemical energy. When automobile starts running, the engine burns the fuel and it converts into kinetic energy with runs the automobile and the energy is converted to heat.

Hence, the correct sequence of energy transformation would be:

A) chemical energy → kinetic energy→ heat energy

Setler [38]

Answer:

The electrical energy consumed by a toaster is 0.033 Kwh.

Explanation:

The power utilized by the toaster is 400 W.

The toaster is operated for 5 Minutes.

We know that,

Substitute the values in the above formula to obtain electrical energy,

Electrical energy = 0.4 × 0.083

Electrical energy is 0.033 Kwh.

Key Stage 3 Science - Physics

stira [4]

Answer:

F = 3750 N

Explanation:

Given that,

Pressure, P = 150 Pa

Area, a = 25m²

We need to find the force applied. We know that, pressure is equal to the force acting per unit area. It can be given by :

$P=\dfrac{F}{A}\\\\F=P\times A\\\\F=150\ Pa\times 25\ m^2\\\\F=3750\ N$

So, the required force is 3750 N.
