Find the pressure exerted on the floor by a 100N box whose bottom area is 40cm x<br> 50cm.
Mazyrski [523]

<u>Answer:</u>

Pressure exerted = 500 Pa

<u>Explanation:</u>

The formula for pressure is as follows:

Pressure = \frac{Force \space\ applied}{Area}

In this case,

Force applied = 100N

Area = 40cm × 50cm = 2000cm² = 2000 × 10⁻⁴ = 0.2m²

Substituting these values into the formula:

Pressure = \frac{100}{0.2}

⇒ Pressure = 500 Pa

If a battery is running down, a light bulb in the circuit will become dimmer because when voltage drops
lana [24]
A. There is less current flowing through the bulb.

Ohms law dictates that Electrical voltage = current x resistance. To understand current you would divide voltage by resistance. The less voltage the less current will run through the circuit.

Mark as brainliest if satisfied.
