A flat-screen TV weighs 147 newtons. The mass of the TV is kilograms. Use g = 9.8 N/kg for gravity.

$\small{ \textsf{ \textbf{ \color{lme}{SOLUTION✍︎࿐}}}}$

The correct answer is 15 kg.

The expression of weight in terms of mass and acceleration due to gravity is as follows;

w=mg

Here, m is the mass of the object and g is the acceleration due to gravity.

It is given in the problem that a flat-screen TV weighs 147 newtons.

Calculate the mass of TV by rearranging the above expression.

m= w/g

Put w= 147 N and g = 9.8 N/kg.

m= 9.8N/kg/147N

m= 15 kg

Therefore, The mass of the TV is 15 kilograms.

Answer 2

Answer:

The mass of the TV is kilograms is 15Kg.

Explanation:

We know that

Weight = Mass/Gravity

Therefore:

Mass = Weight/Gravity

Mass = 147/9.8

Mass = 15 Kilograms.
