Answer: D. solids and liquids only

Explanation:

Solids have definite volume because they have almost no inter-molecular space between its molecule, they are closely packed and rigid in their structure and hence they also have a definite shape.

In case of liquids we have a little inter-molecular space which makes the liquid-bulk flexible enough to attain any shape but this inter molecular space is not sufficient enough to make them compressible making them negligibly compressible. Therefore liquids are also  considered to have a difinite volume.

But in the case of gases there is very large inter molecular space and the molecules make a random motion due to very weak force of attraction between them and the space between the molecules is compressible on the application of force. So, they don't have a definite shape and definite volume.

A skier (m=59.0 kg) starts sliding down from the top of a ski jump with negligible friction and takes off horizontally. If h = 3
marissa [1.9K]

Answer:

35.20 m

Explanation:

By the law of conservation of energy we have,

mg(H-h)=\frac{1}{2}mv^2

g(H-h)=\frac{1}{2}v^2

\Rightarrow H=\frac{v^2}{2g}+h

where m= mass of the skier, h= 3.00 m

D= horizontal distance=13.9 m

H= maximum height attained

Also, the horizontal distance covered by the skier is

D=vt

=v\frac{2g}{h}

\Rightarrow v^2=\frac{gD^2}{2h}

thus, height H in terms of D  is given by

H=\frac{D^2}{2h}+h

H=\frac{13.9^2}{2\times3}+3

H=35.20 m

Katarina [22]
One of the useful forns of the formula for electrical power is: Power = (voltage squared) / (resistance). Knowing that power is proportional to (voltage squared), we can see that if the voltage is reduced to 1/2, the power is reduced to 1/4 of its original value. The 220volt/60watt appliance, when operated on 110 volts, dissipates 60/4 = 15 watts.
