Two large crates, with masses 640kg and 490kg , are connected by a stiff, massless spring (K=8.1kN/m) and propelled along an essentially frictionless, level factory floor by a force applied horizontally to the more massive crate. If the spring compresses 5.1 from its equilibrium length, what is the applied force? Express your answer using two significant figures. The answer is suppose to be 950N

Answers

Answer:

950.7 N

Explanation:

m1 = 640kg

m2 = 490kg

k = 8.1 kN/m

the spring is compressed by 5.1cm

5.1/100 = 0.051m

F = kx

F = 8100 * 0.051

F = 413.1 N

F is the force of the small crate.

F(small) = ma

431.1 = 490a

a = 431.1/490

a = 0.84 m/s^2

The acceleration for the smaller crate is the same for the large create.

F(large) = ma

= 640 * 0.84

= 537.6N

Total force = F(small) + F(large)

= 413.1 + 537.6

= 950.7N

If you want to decrease the current created by a generator what can you do?

Answers

Answer:

To decrease the current;

1) Use fewer loops or number of turns

2) Use a lower speed of rotation of the coil in the magnetic field

3) Use a weaker magnetic

Explanation:

According to Faraday's Law of induction, which is the basis of the electromagnetism, electromagnetic induction and therefore the basis of the electric generator, can be written as follows;

$\epsilon = -N \cdot (\Delta \phi)/(\Delta t)$

Where;

ε = The induced voltage

N = The number of turns (loops)

ΔФ = The change in the magnetic flux

Δt = The change in the time (the duration)

Given that voltage is directly related to the current, decreasing the voltage, decreases the current

To decrease the voltage, and therefore, the current we can;

1) Reduce the number of loops in the coil

2) Increase the time change per unit change in flux by slowing down the speed of rotation of the generator

3) Decrease the amount of change in the magnetic field per turn, by using a weaker magnetic

The kinetic energy of the diver is 5040 J. The speed of the diver is 12 m/s. Calculate the mass of the diver.What's the mass of the diver?

Answers

Answer:

70 kg

Explanation:

We know that,

Kinetic energy = 1/2 mv²

Where m is mass and v is velocity or speed.

Putting the required values,

5040 = 1/2 × m ( 12 × 12)
5040 × 2 = m × 144
10080 = m × 144

divide both side by 144

m = 70 kg

So the mass of the diver is 70 kg respectively.

Which one of the following statements about vitamins is most accurate? A. Vitamins help produce the immune response. B. Vitamins store energy from carbohydrates, lipids, and proteins. C. Vitamins restrict new tissue growth. D. Vitamin overdose restricts reproductive capacity.

Answers

Answer: Option (A) is the correct answer.

Explanation:

Vitamins are the organic compounds which are necessary for normal growth and provide nutrition to the body.

Vitamins help in conversion of food into energy and repair cellular damage.

For example, Vitamin C helps in boosting immune system. Vitamin B6 helps in the biochemical reactions occurring in the immune system.

Thus, we can conclude that out of the given options, the statement Vitamins help produce the immune response is most accurate.

The most accurate statement about vitamins is vitamins help produce the immune response. (Option A)

What are the functions of vitamins?

Vitamins play a crucial role in supporting the immune system by promoting the production and functioning of immune cells, aiding in the synthesis of antibodies, and assisting in the maintenance of overall immune health.

They act as cofactors or coenzymes in various biochemical reactions that are essential for the immune response.

While all vitamins are important for overall health, certain vitamins, such as;

vitamin C
vitamin D, and
the B vitamins

are particularly known for their immune-supporting properties.
