Given :
A 2450 kg stunt airplane accelerates from 120 m/s to 162 m/s in 2.10 s.
If the airplane is putting out an average force of .
To Find :
The average friction force exerted on the airplane by the air.
Solution :
Acceleration is given by :
Now, force equation is given by :
Therefore, frictional force exerted in the airplane by the air is 9810 N.
<h2>Answer: Temperature
</h2>
Temperature is a physical quantity that reflects the amount of heat in a body or medium. This amount of heat is related to the internal energy of a system (thermodynamically speaking), <u>according to the movement (speed) of each of the particles that compose it</u>, this means that it is related to its kinetic energy.
Therefore, the higher the kinetic energy, the higher the thermal energy in the system and the higher the temperature.
Answer:
its the teal/second from the left one
Explanation:
Answer:
Option A
Multiplanar step-up to balance
Explanation:
Resistance training exercises are the exercises that cause the muscles to contract against an external resistance leading to an increase in strength and endurance. Resistance training increases muscle strength by making your muscles work against a weight or force. Considering the options given, it's only Multiplanar step-up to balance which is an example of a strength level resistance training exercise for legs.
