An aircraft travels 1400 km at a speed of 700 km/h

Physics
1 answer:
dolphi86 [110]3 years ago
7 0

Answer:

Total time of flight= 3.6 hours

Speed of flight= 611.1 Km/h

Explanation:

Time taken when moving at 700 Km/h

Since speed=distance/time then time=distance/speed=1400 Km/700 km/h=2 hours

Time taken when moving at a speed of 500 Km/h

Time=800 km/500 Km/h=1.6 hours

Total time taken=2 hours+ 1.6 hours=3.6 hours

Total distance covered= 1400 Km+ 800 Km=2200 Km

Average speed=distance/total time taken=2200 km/3.6 hours=611.1 Km/h

Therefore, average speed is 611.1 Km/h

A car interior is heated to 48 C by the sun What type of energy transfer?
Aneli [31]

Answer:

Radiation heat energy transfer

Explanation:

The type of heat transfer from the Sun is radiation heat transfer, which is the transfer of heat through electromagnetic radiation

The distance of the Sun to the Earth is several million kilometers away, with the space between being composes of vacuum and the nuclear reaction in the Sun's core generates vast amount of electromagnetic radiation that is transferred all across the universe and reaches the Earth as visible light and radiant energy at the speed of light

The radiant energy transferred from the Sun heats up the Earth, including the car's interior.

A body weighs 100newtons when submerged in water. calculate the upthrust action on the body​
Andrews [41]

Answer:

Upthrust = 20 N

Explanation:

The question says that "A body weighs 100N in air and 80N when submerged in water. Calculate the upthrust acting on the body ?"

Upthrust is defined as the force when a body is submerged in liquid, then liquid applies a force on it.

ATQ,

Weight of body in air is 100 N

Weight of body in water is 80 N

Upthrust is equal to the weight of body in air minus weight of body in water.

Upthrust = 100 N - 80 N

Upthrust = 20 N

So, 20 N of upthrust is acting on the body.
