Answer:
ball with a mass of 1 kg is moving in a straight line at the same speed as a ball with a mass of 10 kg
Explanation:
Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain. In other words, isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons
Answer:
diverge light
Explanation:
The refractive index of water is greater than that of air which means that water is more denser than air and also air is optically rarer than water.
Thus,
When the beam of the light is incident from the air to the bubble which contains air, the light bends away from the normal and then the light travels from air to water and bend towards the normal. Thus, the light is first bend away from the normal and then towards the normal which means that the bubble has diverging nature. The light will likely to diverge.

Answer:
P=11.126 atm
Explanation:
We are given that a compressed gas cylinder containing 1.50 mol methane
Volume of methane in a gas cylinder =3.3 L
Temperature =
We have to find the pressure exert by gas on cylinder
Using ideal gas equation
PV =nRT
Where R= gas constant=0.0821 L-atm/K mol
Substitute all given values
Then we get


P=11.126 atm
Hence, the pressure exert by the gas on cylinder =11.126 atm
