10. A boy weighs 475 N. What is his mass? (acceleration due to gravity on Earth is 9.8m/s2 = g)

Darya [45]

Answer: mass = 48.47 kg.

Explanation:

Formula : Weight = mg , where m = mass of body , g= acceleration due to gravity .

Given: Weight = 475 N

$g= 9.8\ m/s^2$

Substitute all values in formula , we get

$475= m \times9.8\\\\\Rightarrow\ m = \dfrac{475}{9.8}\\\\\Rightarrow\ m \approx 48.47\ kg$

Hence, his mass = 48.47 kg.

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.

A single reflection, like shouting at the side of a mountain and hearing
your voice come back to you, is an 'echo'.

Multiple reflection, like clapping your hands once inside a large room,
is 'reverberation'.
