Answer:
Friction
Explanation:
Friction is wasted energy in the form of heat and or destruction.....this is why combustion engines have oil lubriction ====> reduce friction and wear
Answer:
a 10.6 m/s²
Explanation:
Since F = ma (Force = mass * acceleration), acceleration would be...
a = F/m
a = 302 N/28.6
a 10.6 m/s²
Friction made it difficult because an object in motion may not always stay in motion due to the friction caused by its movement. For instance, if you roll a ball down a straight platform, it will not go on forever. The friction of the platform and the ball with eventually slow it down and stop it.
Hope this helps!!
Kinda but a football field is 100 yds. (91.4m), so not really because a Wide Receiver doesn't usually run down the entire field in one play. Also they have to pace themselves because they have to run more than one play in a whole game.
Answer:
F₁ = 10.64 N
Explanation:
The pressure is transmitted equally from the first piston to the second piston:
where,
F₁ = Force applied by compressed air on first piston = ?
F₂ = Weight lifted by second piston = 66.5 N
r₁ = radius of first piston = 10 cm
r₂ = radius of second piston = 25 cm
Therefore,
<u>F₁ = 10.64 N</u>
