Answer: First, question 1 is radiant energy.
Question 2 is nuclear energy
Question 3 is thermal energy
Question 4 is potential energy
Explanation Radiation ( or radiant energy) is high-energy electromagnetic waves. Nuclear energy such as nuclear fusion or fission can change the structure of a nucleus therefore lowering the atomic mass. When molecules vibrate, they produce a lot of energy through friction. That energy is converted into heat. An object that is not in motion but it's position can be altered to be in motion contains potential energy. Once the object gets moving, potential energy is converted into kinetic energy.
Answer:
hmmm
Explanation:
error of parallax or poor measurement
poor structural material
The rms potential difference is defined as the peak value of the potential difference divided by the square root of 2:
where
is the peak value of the voltage (the maximum voltage).
The generator in our problem has a maximum voltage of
, so its rms potential difference is
Automobiles rust faster in wet climate because the chemical reaction between the metal and the iron, oxygen or water
breaks down, or oxidizes, the metal causing the appearance of rust.
Answer:
a) Maximum altitude of the projectile,
b) v = 10885.7 m/s
Explanation:
a) Mass of the earth,
Mass of the projectile =
Launch speed, v = 2.31 * 10³ m/s
Earth radius, r = 6.36 ✕ 10⁶ m
Workdone by the projectile against gravity
...............(1)
Kinetic energy of the projectile:
...................(2)
Equating (1) and (2) based on the law of energy conservation
b) Smallest required change in the satellite speed
Altitude, h = 352 km = 352000 m
Earth radius, r = 6.38 * 10⁶ m
v = 10885.7 m/s
