Answer:

B) Depends on launch speed.

Explanation:

This is true when considering the basketball player in a given basketball game. The speed at which the player jumps up is a strong factor which determines the acceleration of his acceleration. The direct co-relation show that, speed and acceleration of the basketball player are interrelated.

The primary coil of a transformer has N1 = 275 turns, and its secondary coil has N2 = 2,200 turns. If the input voltage across t
DedPeter [7]

Answer:

Secondary voltage of transformer is 905.23 volt  

Explanation:

It is given number of turns in primary of transformer N_1=275

Number of turns in secondary N_2=2200

Input voltage equation of the transformer

\Delta v=160sin\omega t

Here v_{max}=160volt

v_{rms}=\frac{160}{\sqrt{2}}=113.15volt

For transformer we know that

\frac{V_1}{V_2}=\frac{N_1}{N_2}

\frac{113.15}{V_2}=\frac{275}{2200}

V_2=905.23Volt

Therefore secondary voltage of transformer is 905.23 volt

how does electromagnetism effect the function of a generator (using magnetism to produce electrical energy)
Sati [7]

Explanation:

We know that a changing magnetic field induces a current in a conductor. For that reason a generator basically consist an element that produces a magnetic field that changes over time and a conductor where the current will be induced.

This element that produces a magnetic field can be one of the following:

- A permanent magnet: Which is basically like a regular magnet. The magnetic field that a permanent magnet produces does not change over time, we need a motor or any other external force to move the axis of the generator and cause the magnetic field to change.

- An electro-magnet. Which is basically a DC current flowing through a conductor. Basically, when current flows through a conductor it behaves exactly like a magnet. So what we commonly do, is to connect a conductor to a DC battery, and it will create a magnetic field.

Like we are using a DC battery to create a magnetic field, then the magnetic field won't change over time either. So we still need an external force to move the axis of the generator to produce AC electricity.
