Answer:

F=8.45\times 10^{-8}\ N

Explanation:

Given that,

Mass of a boy is 78 kg

Mass of a girl is 65 kg

We need to find the force of gravitational attraction between them if they are 2 m away.

The formula for the gravitational force is given by :

F=\dfrac{Gm_1m_2}{r^2}\\\\F=\dfrac{6.67\times 10^{-11}\times 78\times 65}{(2)^2}\\\\=8.45\times 10^{-8}\ N

So, the force between them is 8.45\times 10^{-8}\ N.

aalyn [17]

Answer:

1.3889 x 10¹¹ miles.

Explanation:

2 Years = 2 x 365 days = 730 days

2 years and 9 days = 739 days .

739 days = 739 x 24 = 17736 hours

2 years 9 days and 4.5 hours = 17736 + 4.5 = 17740.5 hours

17740.5 hours = 17740.5 x 60 x 60 = 63.865 x 10⁶ s

Distance travelled = velocity  x time

2174.799173 x 63.865 x 10⁶ = 1.3889 x 10¹¹ miles.

A 64 kg cross-country skier glides over snow. Thecoefficient
BaLLatris [955]

Answer:

The distance traveled by the skier is 5.309 km

Solution:

As per the question:

Mass of the skier, m = 64 kg

Coefficient of friction between the ski and the snow, \mu_{k} = 0.50

Mass of snow, M = 5.0 kg

Now,

To calculate the distance, 's' traveled by the skier, in order to melt 5.0 kg of snow:

We know that:

f = \mu_{k}N

where

\mu_{k} = coefficient of friction

N = Normal Reaction

N = mg

Thus

f = \mu_{k}mg                           (1)

Also,

fs = ML_{f}                                  (2)  

where

L_{f} = 3.33\times 10^{5}\ J/kg = Latent Heat of fusion

Thus from eqn (1) and (2):

s = \frac{ML_{f}}{\mu_{k}mg}

s = \frac{5\times 3.33\times 10^{5}}{0.50\times 64\times 9.8}

s = 5.309 km
