Answer: B
Explanation:
You can use the conservation of momentum, under the assumption that no mass was lost when the collision occurred. The initial momentum of the system must equal the final momentum of the system. Our system is the region including, and only including, the satellite and the space debris. Classical momentum is defined as the product of mass and velocity:
Due to mass 1 equaling mass 2, we can factor these quantities out:
Cancel the mass term on both sides to get:
We have the initial and final velocities for everything besides the final velocity of the satellite. Plug everything in:
Answer:
c. density decreases because the molecules move farther apart
Explanation:
As a liquid is heated, the molecules move faster and move farther apart. This causes the volume to increase, which causes the density to decrease.
Answer:
<em>The water hits the wall at a height of 5.38 m</em>
Explanation:
<u>Projectile Motion
</u>
It's the type of motion that experiences an object projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.
The object describes a parabolic path given by the equation:
Where:
y = vertical displacement
x = horizontal displacement
θ = Elevation angle
vo = Initial speed
The hose projects a water current upwards at an angle of θ=40° at a speed vo=20 m/s.
The height at which the water hits a wall located at x=8 m from the hose is:
Calculating:
y = 5.38 m
The water hits the wall at a height of 5.38 m
The moon phase shows that D. light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon and Earth are at right angles.
<h3>What is a moon phase?</h3>
It should be noted that the <em>moon</em> phase simply means the portion of the moon that we can see from the Earth.
In this case, the light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon and Earth are at right angles.
