Answer:

A force that is able to act at a distance best describes a noncontact force.

Explanation:

A non-contact force is a force that is exerted between two objects that are not in contact with each other. It is also the force that comes into play when there is no physical interaction between two objects. Gravity is an example of non-contact force.

Consider a situation where you throw an object into the air. This object reaches the maximum height and falls back to the ground. This is due to the non-contract force(Gravity). Hence a non-contract force is a force that acts at distance. The other examples of non-contact forces are magnetic force, electrostatic force, nuclear force.

IRINA_888 [86]

Answer:

Inertia

Explanation:

When the planes moves downward a speed, the weight of the person will decrease a bit due to the amount of g decreases for that particular instant. The person is now experiencing a less than actual weight called as apparent weight due to the upward superposition of inertia on the body as we can see in w = m g .

Group of physics students are asked to demonstrate Ohm’s Law in parallel circuits. Using their knowledge of Ohm’s Law and the r

astra-53 [7]

The student’s suggestion who provides enough evidence to be able to determine the value of each resistor is student D.

<h3>What is current?</h3>

The current is the stream of charges which flow inside the conductors when connected across the end of voltage.

For the given set of parallel resistors, we need to find the resistance of each resistor.

From the Ohm's law, V =IR

R = V/I

Resistance value depends upon the voltage difference across the resistor and the current flowing through that resistance.

Thus, the student D gives enough evidence to find resistance of the circuit is

How much energy does the electron have initially in the n=4 excited state?what is the change in energy if the electron from part

Ierofanga [76]

What it looks to be that you found in A was the "initial"...b/c the question asks:
"how much energy does the electron have 'initially' in the n=4 excited state?" 

"final" would be where it 'finally' ends up at, ie. its last stop...as for this question...the 'ground state' as in its lowest energy level. 

The answer comes to: −1.36×10^−19 J

You use the same equation for the second part as for part a.
just have to subract the 2 as in the only diff for part 2 is that you use 1squared rather than 4squared & subract "final -initial" & you should get -2.05*10^-18 as your answer.

Why is nuclear energy an important discussion in today's world?

aksik [14]

Answer:

Nuclear energy is not limited to the generation of electricity, but may equally well be used for such important tasks as desalination, production of hydrogen, space heating and process-heat applications in industry as well as for extraction of carbon from CO2 to combine with hydrogen to create synthetic liquid fuels.

Lorico [155]

Answer:

675 A

Explanation:

B = 1.5 x 10^-8 T

r = 9 km = 9000 m

Let the current be i

The formula for the magnetic filed due to a very long straight conductor is given by

$B =\frac{\mu_{0}}{4\pi }\times \frac{2i}{r}$

$1.5\times 10^{-8} =10^{-7}\times \frac{2i}{9000}$

i = 675 A
