Answer: The wheel's average rotational acceleration is -0.4 radians per second squared (rad/s^2)
Explanation: Please see the attachments below
Answer:
<em>a. ratio = 40</em>
<em>b. 4 houses can be supplied</em>
Explanation:
<u>Relations in a Transformer</u>
The pole-mounted transformers are mainly used to lower higher distribution voltages to residential-level voltages. It is done by using a combination of primary and secondary coils so the relation or ratio is correctly achieved.
a. The ratio between the number of turns in the primary coil to the secondary coil is
b. This ratio also applies to the primary and secondary currents, being the secondary current r times the primary current.
The ratio between the currents is given by
We can know the secondary current
Given each house requires 40 A rms, we can supply electricity to 160/40=4 houses
Because the molecules are vibrating. Also keep in mind that when a substance is a solid its molecules are tightly packed. When it is a liquid its molecules are less compact
B. Doldrums. I cant actually explain it i just know its the answer
