A high-energy proton is ejected from the sun at 0.400 c; it is gaining on a proton ejected at 0.330 c. According to the slower proton, with what speed is the faster proton gaining on it? Express your answer in the units of the speed of light.
A high energy proton from the sun enters the Earths magnetic
field at a speed of 6.0x10^6 m/s perpendicular to the field lines.
The field is uniform and with strength B=4.5x10^-5 T.
a) What is the magnetic force on the proton when it first
enters the B-field?
b) Calculate the radius of the protons path in the B
field.
c) determine the frequency and the period of the protons
orbit.
The Earth absorbs energy emitted from the sun. If the sun emits energy at a rate such that the emitted power is 3.9x1026W how much power is incident on the earth? (Hint, you may need to look up the Earth-Sun distance and radius of the Earth.)
The Earth receives energy from the Sun at the rate of 1.4 kW/m . A sister planet orbits a star at the same distance as the Earth’s distance from the Sun. If the sister planet’s star has a temperature 2.1 times that of the Sun’s temperature, what is the rate that the sister planet receives energy from its sun?
In its core the Sun changed, hydrogen into helium and produces energy by this nuclear fusion process. Each hydrogen atom has a positively charged center (a proton) and a negatively charged electron that exists around the periphery of the atom. The heat of the Sun pulls the electrons off the hydrogen atoms, leaving positively charged protons behind. To make energy the sun has to force these positively charged particles very close together so that a very strong but short range...
Warm Up The surface of the Earth receives approximately 1000 W/m2 (Watts per square meter) of energy from the Sun. This number rises to about 1386 W/m2 in the upper atmosphere (r 6.4 x 106 m) The sun is 1 AU (1.496 x 1011 m) away Over what area is the Sun's energy spread at the Earth's distance? How much power is the Sun releasing?

What is the angular kinetic energy of the Earth due to its orbit around the sun? In Homework 10, you found the two main angular velocities of the Earth: one due to the Earth's motion around the sun, and one due to its rotation about its own axis. Now let's figure out the energy and momentum associated with that motion. IVO ALV O a ? For the purposes of this problem, treat the Earth as a solid, uniform sphere with...
Consider potential radiative energy balance at the surface of the Earth, with the Sun directly overhead in the sky. Assume that the incident solar radiative flux is reduced passing through the atmosphere to 0.85 times the TOA value, and that 20% of this is reflected at the ground. Calculate the temperature that the surface (radiating as a blackbody) would need to be at in order to be in instantaneous radiative energy balance with the solar radiation. What would you say...
1 What is the Earth's orbital speed as it orbits the Sun. Take the Earth/Sun distance to be 93 million miles (taking the Earth's orbit to be circular), the mass of the Earth to be 5.97 X 102 kg and the mass of the Sun to be 1.987 X 10*0 kg. Solve this problem using Newton's 2nd law directly 2. A 55.7 kg mass is lifted (at a constant velocity) from the ground to a vertical height of 1275 m....
11. How much energy from the Sun would the Curiosity Rover collect at Mars' average distance from the Sun of 1.52 AU, compared to how much that solar panel would collect at Earth? (Ignore any losses in energy due to the atmospheres of either body.) (The /is the division symbol.) a. 1/1.52 = 0.66) as much as received at Earth b. 1/(1.52 x 2) as much (= 0.33) as received at Earth c. 1/1.52 times as much (= 0.43) as...
