Answer:
c. turn downward
Explanation:
From the information given:
To find the tendency of the sander;
We need to apply the right-hand rule torque; whereby we consider the direction of the flywheel, the direction at which the torque is acting, and the movement of the sander toward the right.
Since the flywheel of the sander is in counterclockwise movement, hence the torque direction will be outward placing on the wall. However, provided that the movement of the sander is toward the right, then there exists an opposite force that turns downward which showcases the tendency in the sander is downward.
Answer:
Force = mass × acceleration
Acceleration:
From first Newton's equation of motion:
Change = v - u:
Answer:
I = 20 A
Explanation:
The question says that, "A load of 6,000 C is conducted through a cross section in 5 minutes. Determining-if a current is not correct, we will find the value of?"
We have,
Charge, q = 6,000 C
Time, t = 5 minutes = 300 s
We need to find the current. We know that, the charge flowing per unit time is equal to current. So,
So, the current flowing through the circuit is 20 A.
Answer:
f=4Hz
Explanation:
frequency of a wave if it has a wavelength of 3.0 m and a wave speed of 12m/s
v=fλ → f=v/λ
f=12/3
f=4Hz
