The average speed is 615.7 mph (275.2 m/s)
Explanation:
The average speed of an object gives a measure of how fast an object is moving over a certain time interval. It is a scalar quantity, and it is calculated as follows
where
v is the average speed
d is the distance covered
t is the time interval
For the jet in this problem, we have:
d = 1293 mi is the distance covered
t = 2.1 h is the time interval
Therefore, the average speed is:
We can also convert into SI units (m/s), keeping in mind that:
And so

Answer: Heat
Explanation: Heat is a form of energy, and it is exchanged between bodys when they are not at the same temperature.
Heat is transferred from the body with higher temperature to the one with lower tempertature, this is so that in time they end up being at the same temperature.
This means that the one with lower temperature is the one who absorbs the heat, and the one with higher temperature transfer it.
Answer:
They are temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness. Together, these components describe the weather at any given time.
Answer:
the balloon is filled with the 8.5 litre of helium. temperature is 294 kelvin.
party starts at 4 p.m.
the temperature rises 305 kelvin.
the new volume = 4 litres
Answer:
5 km
Explanation:
displacement is the straight line distance from a particular point. since north and south are in opposite directions, it means that he has taken a u-turn
thus, 10 - 5 = 5km displacement
