Earth's atmosphere is made up of several different elements,
nitrogen - 78%
oxygen - 21%
argon - 0.9%
carbon dioxide - 0.03%
and lastly water vapor with 0.0-4.0%
Answer:
It would eventually crash into the Sun
Explanation:
If the mars is orbiting around the sun, the gravitational force of attraction is between the sun and mars supply the necessary force required for the centripetal motion.
If a planet is in centripetal motion, it is constantly falling towards the sun with the acceleration equal to the gravitational strength at that point.
If the centripetal acceleration of the planet is removed, still the planet would accelerate linearly falling towards the sun.
Hence, if the planets tangential velocity was reduced to zero, It would eventually crash into the Sun
Answer:
306J
Explanation:
The formula for kinetic energy is given as ½mv².
Using this, we get our answer by substituting the values into the formula.
½ × 0.145kg × 65m/s
= 306.31J
can be rounded off to 306J
B. picking up a box off the floor
C.) chemical to electrical to light
