Answer :
TRUE
Explanation :
Helium is lighter and is much less dense than most of the gases in our atmosphere hence the blimp, if filled with helium will float in air
Answer:
A, the amount of charge stored per volt
Explanation:
The equation for capacitance is
C = Q/V
therefore, it is charge per volt
Answer:
It is worth noting that the higher the gravitational energy of an object moving downwards, the lower the kinetic energy, and the lower the kinetic energy of an object moving upwards, the higher its gravitational energy.
Gravitational potential energy is acquired by an object when it has been moved against a gravitational field. For example, an object raised above the surface of the Earth will gain energy, which is released if the object is allowed to fall back to the ground.
given that initial speed of the car is
now after travelling the distance d = 1.8 * 10^1 m the car will stop
so here we can use kinematics to find the acceleration of car
here we have
net force applied due to brakes of car is given by Newton's II law
here we have
mass = 1.2 * 10^3 kg
now we can say
So the force applied due to brakes is given as above
Each time they collide with the walls they exert a force on them. More collisions mean more force, so the pressure will increase. When the volume decreases, the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume.
