Answer:
750cm³
Explanation:
volume = length × width × height
15 × 10 × 5 = 750
750cm³
Answer:
Action and reaction are the same
Explanation:
Let us carefully analyze the situation in the context of Newton's third law, when the car hits the mosquito exerts a force that acts on the mosquito, ACTION and the mosquito responds to the force that is being applied with a force of equal magnitude and direction or opposite applied to the car (Reaction).
Consequently, the correct answer is: The force of the car on the mosquito is of the same magnitude as that of the mosquito on the car
Measure the length of one side and then cube the answer. So if x represents the measurement of one side, x³ will give you the volume.
The total momentum of the system (astronaut+gas) must be conserved.
We can assume the astronaut is still before the gas starts to be ejected, therefore its speed is zero and its momentum is zero as well.
After the gas starts to be ejected, the total momentum of the system is:
where
is the mass of the astronaut,
is the speed of the astronaut,
is the mass of the gas and
is the speed of the gas.
Since the momentum must be conserved, and the initial momentum was zero, then it must be
. Using this information, we can find the value of
, the speed of the astronaut:
where the negative sign means that the astronaut starts to move in the opposite direction of the ejected gas.
