A thin rod of length 1.4 m and mass 180 g is suspended freely from one end. It is pulled to one side and then allowed to swing l

prisoha [69]

Answer:

$K.E = 0.1905 J$

Explanation:

From the question we are told that:

Length $L=1.4m$

Mass $m=180g$

Angular Velocity $\omega=1.80rads/s$

Generally the equation for Kinetic energy K.E is mathematically given by

$K.E =0.5 (1/3 ML^2 )w^2$

$K.E =0.5 ( 1/3 * 0.18 * 1.4^2 ) 1.8^2$

$K.E = 0.1905 J$

A person eats a container of strawberry yogurt. The Nutritional Facts label states that it contains 255 Calories (1 Calorie = 41

Sever21 [200]

Answer:

mass = 0.44 Kg

Explanation:

given,

Calories contain in the strawberry yogurt = 255 calories

1 Calorie = 4186 J

latent heat of vaporization = 2.42 x 10⁶ J/Kg

mass of perspiration = ?

Energy = 255 calories

Energy = 255 x 4186

= 1067430 J

Energy = mass x latent heat of vaporization

$mass = \dfrac{Q}{L_v}$

$mass = \dfrac{1067430}{2.42 \times 10^6}$

mass = 0.44 Kg
