Answer:
8 mph
Explanation:
4 miles in half hour so you add 4 more for the second half
Answer:
This difference is kept to a minimum because the resistance in transformers is a few tens of ohms and the resistance of modern voltmeters is of the order of MΩ.
Explanation:
A voltmeter is built by a galvanometer and a resistance in series, this set is connected in parallel to the resistance where the voltage is to be measured, therefore the voltage is divided between the voltmeter and the element to be measured, consequently the measured voltage It is less than the calculated one, since for them the resistance of the voltmeter is assumed infinite.
This difference is kept to a minimum because the resistance in transformers is a few tens of ohms and the resistance of modern voltmeters is of the order of MΩ.
It will be 49 Newtons of force in the down direction. To find the force in newtons, you multiply the mass (5 kg) by the gravity (which if 9.8).
Answer:
The electric flux is zero because charge is zero.
Explanation:
Given that,
Positive charge
Negative charge
We need to calculate the total charged
Using formula of charge
Put the value into the formula
We need to calculate the electric flux
Using formula of electric flux
Put the value into the formula
Hence, The electric flux is zero because charge is zero.
