Answer:
work accomplished = 300*30
= 9,000 J
applied work = 9,000 + 2,000 = 11,000 Joules
efficiency = 100 * work accomplished/work applied
= (9/11)100 = 81.8 %
force applied = (300/6)/.818
= 61.1 N
assuming that the 6 in your question refers to mechanical advantage
They signed the <em>Halibut</em> Treaty of 1937.
Answer:
D. The friction force increases by 9600 N.
Explanation:
Frictional force is directly proportional to kinetic coefient of friction.
<h3><u>Answer;</u></h3>
A. Their bodies will move forward.
<h3><u>Explanation</u>;</h3>
- <em><u>When a train or a bus comes to a sudden stop everything including the passengers that is not directly attached to the train or the vehicle will tend to continue in the direction of travel, thus the bodies of the passengers will move forward.</u></em>
- This is<em><u> due to the forces of inertia.</u></em> From the second Newton's law of motion, a body will main at its state of rest or constant speed unless acted upon by an unbalanced external force.
- <em><u>When the train suddenly stops the tendency of inertia of motion of the passengers results in the forward motion throwing them from their seats.</u></em>
