The correct answer to the question is : Air resistance.
EXPLANATION:
Before coming into any conclusion, first we have to understand the terminal velocity.
An object is said to be moving with terminal velocity if the net force acting on the object is zero i.e the body is non accelerating.
As per the question, the object is falling under gravity. The force of gravity acts in vertical downward direction.
Except gravity, the object is also under air resistance. It is the force which opposes the motion of the object, and acts in vertical upward direction.
If the air resistance becomes equal to force of gravity, then the net force acting on the object is zero . It is so because two forces act in opposite direction.
In case of liquids, the resistance force is called as viscosity.
Hence, the correct answer to the question is air resistance.
Answer:
The observed temperature was 10º Celsius or 50º Fahrenheit.
Explanation:
The traveler observed that the temperature in Fahrenheit is five times the value of the temperature in Celsius, therefore:
A Fahrenheit temperature relates to a Celsius one by the following expression:
Using the second expression on the first, we can solve for the temperature in Celsius, this is done below:
The observed temperature was 10º Celsius or 50º Fahrenheit.
B. The Earth radiates an amount of energy into space equal to the amount it receives.
Part of the solar energy is reflected by the Earth into space, this is known as albedo. The other part of the energy radiated by the Earth in the form of infrared radiation, is absorbed by the greenhouse gases, which cause most of this infrared radiation to be emitted into space. Therefore, the net flow of energy is zero.
Answer:
1.
Jupiter is the largest planet in the solar system. (Image credit: NASA)
The largest planet in the solar system, the gas giant Jupiter is approximately 318 times as massive as Earth. If the mass of all of the other planets in the solar system were combined into one "super planet," Jupiter would still be two and a half times as large.
2.Rotation of Jupiter

Jupiter has the fastest rotation of all the planets in the Solar System, completing one rotation on its axis every 9.9 hours.
3.Jupiter, the King of the Planets, is a gas giant, which means that it's made mostly of gases like hydrogen and helium, and that it doesn't have a solid surface in the way that rocky planets like Earth do. With a temperature of 130 K (-140 C, -230 F), it's so cold that it gives off most of its energy in the infrared. In fact, Jupiter gives off almost twice as much heat as it receives from the Sun. It's able to do this because it has its own internal heat source, powered by the slow gravitational collapse that started when the planet first formed. Astronomers estimate that Jupiter is currently shrinking by almost 2 cm per year
