Answer:
0.0815
Explanation:
Mechanical advantage is output force/input force. So all you have to do is 55.0N/675N ~ 0.0815
Hope this helped!
Answer:
Ah good question um no u dont have to be near it its a vr thing ur gonna have it on u the whole time. You can only be a few feet away from ur tv if u chose to do it on there or u can do it on ur phone but its also the same distance.
Explanation:
Answer: 63% of the final charge
Explanation:
When a capacitor is connected to a battery/power supply, the capacitor charges following the exponential law:
where
is the final charge of the capacitor, which is
where C is the capacitance and the potential difference of the battery
t is the time
is the time constant of the circuit
Re-writing the equation,
After a time equal to one time constant,
Therefore the charge on the capacitor will be
Which means 63% of the final charge.
Answer:2.5 mph
Explanation:
Total time for trip=6 hr
Speed of roy=5 mph
the trip 4 miles one side
Let v be the stream velocity
time=
Answer:
As it moves farther and farther away from Q, it's speed will keep increasing.
Explanation:
This is so because the point charges are both positive charges and positive charges repel.
As the charges repel, they do so at an increasing speed.
