Explanation:
In local galactic group the force of expansion of universe is overcome by the force of attraction due to gravity. Best example is our own galaxy milky way and another giant galaxy in our local group Andromeda. Andromeda having enormous gravity is pulling milky way towards itself, overcoming the force of expansion.
So, there are possibilities of collision despite the expansion of universe at a rapid pace. It is estimated that the milky way and Andromeda will collide each other after about 50 billion years from now.
Accelerated motion such as a vehicle (car) or a moving item such as a (football thrown in the air)
The correct answer is Mechanics
Answer: 0.08K
Explanation:
When temperature changes, the corresponding change in thermal energy of a gas is given by:
ΔE (thermal) = 3/2nRΔT
Defining the parameters:
ΔE (thermal) = Increase in thermal energy of the mono atomic gas = 1.0J
n = number of moles of the gas = 1.0mol
R = Ideal gas constant = 8.314J/mol/K
ΔT = change in temperature. This is what we need to find.
Rearranging the equation to make ΔT subject of the formula,
ΔT= 2 x ΔE (thermal) / (3 x n x R)
Therefore, ΔT = 2 x 1.0J / (3 x 1.0mol x 8.314J/mol/K)
ΔT = 2.0J / 24.942J/K
ΔT = 0.0802K
ΔT = 0.08K
The temperature change of 1.0mol of a monoatomic gas if its thermal energy is increased by 1.0J is 0.08K.
Initial Velocity = 0
Final Velocity=3
Duration of time=0.5
Acceleration=6
I hope that helped. Good luck!
