Answer:

<h2>If the forefinger points in the direction of the magnetic field and the middle finger in the direction of the current, then, the thumb points in the direction of the force exerted on the conductor.So, if the current is reversed in the conductor placed in a magnetic field the direction of force is also reversed..</h2>

The unit used to measure electric current is the ampere (A). Now, assume that the current delivered at a wall socket reaches the

pav-90 [236]

Answer:

T = 0.017s

Explanation:

period is the time it takes a particle to make one oscillation

An electric current is periodic in nature

The current reaches 3.8A ten times.

So there must have been 10 cycles (10 periods) in 0.17s. let 'T' be the period:

$T=\frac{t}{n}$

t is the total time interval

n is the number of oscillations

$T=\frac{0.17}{10}$

10T = 0.17

T = 0.17/10 = 0.017s

24 POINTS!!!!!!!!!!!!!!!

TEA [102]

Potential Energy (Initial one) = m * g * h
P.E. = 60 * 9.8 * 10
P.E. = 5880

Kinetic Energy (Final One) = 1/2 mv²
K.E. = 1/2 * 60 * (10)²
K.E. = 6000/2
K.E. = 3000

Lost Energy = 5880 - 3000 = 2880 J

In short, Your Answer would be 2880 Joules

Hope this helps!

Discuss the pros and cons of fission and fusion reactions.

Jet001 [13]

Fission: -

Pros:

- "It does not contribute to the air pollutants in the environment."

- "It does not need costly energy fuels."

- "It is capable of providing energy for 2 to 3 years."

- "It does not make global warming worse."

- "It produces a nuclear reaction that is important."

- "It helps with the field of astronomy."

Cons:

- "It can harm the environment in a way that it disposes waste."

- "It poses a risk to public health."

- "It can cause deadly and costly accidents."

- "It has the potential to open the door for terrorists to create powerful weapons."

Fusion Reactions: -

Pros:

- "Clean energy ."

- "Virtually limitless fuel available ."

- "No chain reaction. Easier to control or stop than fission ."

- "Nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei) ."

- "Little or no nuclear waste. Core remains radioactive for only 100 years. Possibly radioactive structural elements ."

- "Very low fuel cost."

Cons:

- "Unproven (it will take another years of research to explore it on commercial scale) ."

- "Commercial power plants will be very expensive to build ."

- "Requires extremely high temperatures .

If cold fusion could be achieved, it would be much easier to implement."

Which law applies to the picture? Newtons 1st Law? Newton's 2nd Law? Newton's 3rd Law?

jeka57 [31]

Answer:

Newtons 1st Law.

Explanation:

Because it states as every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

Why do you need to evaluate claims made on product labels?

KATRIN_1 [288]

Answer:

Option D, The claims may be biased, is the right answer.

Explanation:

Option D is the correct answer because the primary motive of a company is to earn more profit and it can misguide the consumer by making false and biased claims. Therefore, the evaluation of the claims is the responsibility of the buyers which help them to buy the product beneficial to them. For example, if a product claims that it will glow your skin within seconds then it is the awareness or activeness of the consumer to evaluate such claims which are written on the label and cross verify the ingredients that are used in it because such claims can be false to sell the product.
