7 0

True. This is because the gas molecules in outer space are too far apart, sound needs a medium to travel through unlike light.

They only conduct when they are in solution form, because then their ions become mobile, and the ions conduct electricity.

Hope this helps!

Newton’s second law is a=F/m this is what we will be using to solve this
However first you need to convert g to kg
100g= 0.1kg

0.05/0.1=0.5 m/s^2

Answer:

1.034 m above the floor

Explanation:

The location of center of body for a compound body, when the weights are given is calculated as:

$\bar x = \frac{W_1x_1+W_2x_2+W_3x_3+W_4x_4+W_5x_5+.......+Wnx_n}{W_1+W_2W_3W_4W_5+.....+W_n}$

where,

$\bar x$ is the center of gravity of the entire body

W = weight of the individual body

x = center of gravity of the individual body

Thus on substituting the values we get,

$\bar x = \frac{438\times 1.28+144\times 0.760+87\times 0.250}{438+144+87}$

$\bar x = \frac{691.83}{669}$

$\bar x =1.034m$

Hence, the center of gravity of the entire body lies 1.034 m above the floor
