The weight of an object is the product of its mass, m, and the acceleration of gravity, g(whereg=9.8m/s2). if an object’s mass ism=10.kg, what is its weight?

98 N

Explanation:

Wight is the force with which our earth attracts any body towards its centre.

Weight of the body is defined as the product of mass of body and the acceleration due to gravity at that place.

the SI unit of weight is same as the force that means it is newton and the CGS unit is dyne.

1 newton = 10^5 dyne

Weight = mass of the body x acceleration due to gravity

mass, m = 10 kg

g = 9.8 m/s^2

Weight, W = m x g

W = 10 x 9.8 = 98 N

radiation

explanation:

heat is transmitted by radiation
