Kinetic energy = (1/2) * mass * velocity
Marble 1 = (1/2) * 10 * 3 = 15 Joules
Marble 2 = 30 J
Marble 3 = 37.5 J
Marble 4 = 60 J
Marble 5 = 45 J
Marble 4 has the most kinetic energy - D.
The correct answer is B. wrap more coils of wire around the nail. This is how you can increase its magnetic strength. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
Answer:
because the wavelength of electron beams is much shorter than the wavelength of visible light
The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun at it travels through its year long pat around the sun.
Answer:
density
Explanation:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
