<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>
Answer: B
Explanation:
1) Apply Ampere's Law to the loop
The loop has a circumference of 2pir.
The current enclosed is multiplied by N because there is N distinct loops.
Answer is B
Average speed = (total distance) / (total time).
Total distance = (100 miles + 30 miles + 75 miles) = 205 miles
Total time = (2 hours + 1 hour + 1 hour) = 4 hours
Average speed = (205 miles) / (4 hours) = 51.25 miles/hour
Rounded to the nearest whole number, that's 51 mph .
Answer:
The moment of inertia of the wheel is 0.593 kg-m².
Explanation:
Given that,
Force = 82.0 N
Radius r = 0.150 m
Angular speed = 12.8 rev/s
Time = 3.88 s
We need to calculate the torque
Using formula of torque
Now, The angular acceleration
We need to calculate the moment of inertia
Using relation between torque and moment of inertia
Hence, The moment of inertia of the wheel is 0.593 kg-m².
