Elaine can use a resistor in her circuit to reduce the rate of flow of charge(current), as a resistor resists the flow of charges, so it's amount would be reduced.
In short, Your Answer would be Option C) "A Resistor"
Hope this helps!
Answer:
V = 42187 m/s = 42.18 km/s
Explanation:
given data:
mass of sun is
radius of earth orbit is
minimum speed can be determined by using following formula
}
where G is
Plugging all value to get desired value
V = 42187 m/s = 42.18 km/s
Just multiply 9.8 m/s ( earths gravity ) by the time 3.5 seconds.
Answer:
W = 132,167.7 J
Explanation:
given
mass = 333 kg
distance = 9.00 m
angle = 30°
external force = 4575 N (parallel to plane )
(1) work done by the external force.
w = f.d
w = 4575 × 9 = 41175 J
(2) work done by gravity.
W = 132,167.7 J
Answer:
1.8m/s^2
Explanation:
Since the two ropes are going up, their combined force is 105+115=220N. With a gravitational force of 186N, the force of the two ropes pulling up the will be 220-186=34N.
Now we need the mass of the bucket itself in order to find the acceleration of the bucket (remember that F=ma and m is needed to find a). Since gravitational acceleration is 9.8m/s^2 and F=186N, 186/9.8=18.97959184 kg for the mass of the bucket.
Now that we have the mass of the bucket, we can find the acceleration of the bucket. Since F=34N from earlier, 34N/18.97959184kg=1.791397849m/s^2=1.8m/s^2 is the acceleration of the bucket.
Therefore, 1.8m/s^2 is the correct answer.
