Answer:
i think the answer is "B"
Explanation:
the particles in a gas are more far apart and have more kinetic energy than liquid because they are more close together and have less kinetic energy than gas.
Answer:
.000828 j
Explanation:
Work = F * d
.0069 N * .12 m = .000828 j
Explanation:
Condensation is the process of changing the physical state of matter, from gas to liquid state. During condensation of matter, the physical state of the matter changes. Now in this question it is asked that what happens to the steam during the process of condensation. So steam is the matter, and during this process, steam converts its molecules from gaseous to the liquid state without heating. After this process, the steam is converted back to its liquid state. The liquid now take less space than that of the gas and exert less pressure on the walls of the container.
Answer:
Absence of light causes shadow
Explanation:
The shadow is of the black colour because it is formed by the white light from the sun. Black is the opposite colour of white. In case you use different colour of light to cast a shadow you will get a shadow of opposite colour of light used to cast shadow.
Let the mass be m
v = 5m/s
K.E = 25 J
K.E = 1/2 mv^2
25 = 1/2 m (5)^2
25 x 2 = 25m
m = 2 kg
Now if the velocity becomes 3 times then the velocity is 3 x 5 = 15m/S
Now new K.E = 1/2 x 2 x 15^2
= 225 J
