Answer:
1 m/s west
Explanation:
Impulse = change in momentum
J = m Δv
Taking east to be positive:
300 kg m/s = (75 kg) (v − (-5 m/s))
v = -1 m/s
His new velocity is 1 m/s west.
Answer:
An electron tube from which all air has been removed. The vacuum ensures transparency inside the tube for electric fields and moving electrons. Most electron tubes are vacuum tubes; cathode-ray tubes, which include television picture tubes and other video display tubes, are the most widely used vacuum tubes

Answer: The correct answer is option (D).
Explanation:
The area under the line is 10 meters that is displacement which means that area enclosed by the right angled triangle is 10 unit squares.
So, the it can be written as:



Hence the, the correct answer is option (D).
1.) Electrons go back into like a lower energy level then would be release a thing called a photon light.
2.) I'm not sure on the correct numbers exactly but if I remember correctly around 70-80 percent is nitrogen, around 20-25 is percent oxygen, 0.9 percent is argon, and 0.1 percent other gases.
3.) Glass is made from sand at least that's one popular element of making sand. one gathered, they are put into a high temperature and would soon make glass coming out of it within time.
