The value of the thrust developed by the engine of a boeing 777 in N and Kgf are ;
i) 376616N
ii) 38430Kgf
<h3>What is force?</h3>
Force is a push or a pull. The reactive force always serve to balance the applied force. We are here asked to convert the the thrust developed by the engine of a boeing 777 which is about 85400 lbf to the following units;
i) N
ii)kgf
Thus;
1 Ib = 0.45 Kg
1 lbf = 0.45 Kg * 9.8 m/s^2 = 4.41 N
We know that;
1 lbf = 4.41 N
85400 lbf = 85400 lbf. * 4.41 N/1 lbf
= 376616N
Again;
1 lbf = 0.45 Kgf
85400 lbf = 85400 lbf * 0.45 Kgf/1 lbf
= 38430Kgf

Answer:
D.) Heat the jar in a microwave oven.
Explanation:
This is equivalent to asking the mass’s weight. Force=mass * acceleration. So 7*9.8= 68.6 N
False
Explanation:
Loudness is the human perception of sound intensity and not pitch. Pitch is a property of waves.
Loudness measures the intensity of sound to the hear and the frequency is often expressed in decibels.
- Pitch is how high or low a note is being played.
- It is a property that makes it to judge whether sounds are high or low.
- Loudness on the other hand is depends on the human perception of how high or low sound is to a person.
