T = 3 h = 3 x 3600s = 10800s
d = 100 x 10800 = 1080000km to The east.
In a circuit, if the resistors were decreased by a factor of 1,000, it is true that the current would increase by a factor of 1,000, according to Ohm's Law.
<h3>What is Ohm's Law?</h3><h3 />
It is a law in electricity that posits that the voltage that goes through a conductor is directly proportional to the current.
<h3>How does Ohm'slaw explain the change in current?</h3>
One formula in Ohm's law is:
Voltage = Current x Resistance
If the resistance were to decrease by a factor of 1,000, the current would have to increase by a factor of 1,000 as well in order to give the same voltage.

Answer:
a) 4.0 rad/s2
Explanation:
- For rigid bodies, Newton's 2nd law becomes :
τ = I * α (1)
where τ is the net external torque applied, I is the rotational inertia
of the body with respect to the axis of rotation, and α is the angular
acceleration caused by the torque.
- At the same time, we can apply the definition of torque to the left side of (1), as follows:
where τ = external net torque applied by Fnet, r is the distance
between the axis of rotation and the line of Fnet, and θ is the
angle between both vectors.
In this particular case, as Fnet is applied tangentially to the disk, Fnet
and r are perpendicular each other.
- Since left sides of (1) and (2) are equal each other, right sides are equal too, so we can solve for the angular acceleration as follows:
Answer:
Work hasn't been done by Michael because no distance was covered.
Explanation:
Workdone is given by the formula;
Where;
W is the work done
F represents the force acting on a body.
s represents the distance covered by the body.
Hence, work hasn't been done by Michael because no distance was covered, as the table didn't move at all. Therefore, work done is zero.
Answer is B, it can be positive or negative, as long as it has a charge.
