4 0

Answer:

Technician A and Technician B both are right.

Explanation:

In an AC alternator,  there are two windings

1. Stator winding (stationary)

2. Rotor winding (rotating)

The current is induced in the stationary coils due to the magnetic field produced by the rotor. The DC suppy is provided to the rotor winding via slip rings and brushes and a voltage regulator precisely controls this supply to control the current flow through the rotor.

Therefore, both technicians are right.

Answer:

Biodiesel is considered a renewable energy source because it is made with animal fat

Explanation:

Biodiesel is a fuel generated from animal fats, vegetable fats, using a catalyst for chemical formulation of biodisel.

It is a renewable source of fuel, as it can be replenished (renewed) easily & in shorter time, since it is made of animal fats & vegetable fats. Unlike non renewable fuels which take long periods to replenish (renew), like fossil fuels.

So, Biodiesel is considered a renewable energy source because it is made with animal fat

The less mass an object has, the --- its gravitational f
BaLLatris [955]

Answer:

<em>The less mass an object has, the </em><u>less</u><em> its gravitational  [force.]</em>

Explanation:

Newton's Law of Gravity states that F_G=\frac{Gm_1m_2}{r^{2}}. The two <em>m</em> values are the objects' masses, G is the gravitational constant, and <em>r</em> is the distance between the objects' centers. Notice how the mass values are in the fraction's <em>numerator</em>? That means <em>increasing</em> the mass of one or both objects <em>increases</em> F_G. That also implies the inverse; <em>decreasing</em> the mass of one or both objects <em>decreases</em> F_G!

I hope this helps you understand this concept a little more! Have yourself a fantastic day, 'kay?

marin [14]
Using conservation of momentum, we can solve for the force that the air bag exerts on the person.

Recall the equation for momentum (p):

p = mv = F*dt

We can solve for total momentum, then divide by out time interval. This gets us:

(60kg)(16m/s) = F(0.2s)&#10;&#10;&#10;F = 4800N

F = 4800N
