Answer:

No, The Moon, on the other hand, rotates once around its every 28 days, and once around the Earth in that same 28 days. The result of this combination is that the same side of the Moon is always facing the Earth.

True [87]

1). the total voltage between the ends of the series circuit was constant.
The resistance of the circuit and the current through the circuit changed.

2). The voltage between the end terminals of the parallel circuit is constant.
The resistance of the circuit and the current through the circuit changed.

3). So that you can avoid building a circuit that needs more current
than your battery can supply, and also to be sure and choose a battery
or power supply that's able to deliver the amount of current that your
circuit needs.

A long, thin solenoid has 950 turns per meter and radius 3.00 cm. The current in the solenoid is increasing at a uniform rate of

REY [17]

Answer:

Part a)

$E = 0.188 \times 10^{-3} N/CPart b)[tex]E = 0.376 \times 10^{-3}$ N/C

Explanation:

As we know that the magnetic field near the center of the solenoid is given as

$B = \mu_0 ni$

Also we know by equation of Faraday's law

EMF induced in the closed loop will be equal to rate of change in magnetic flux

so we have

$EMF = A\frac{dB}{dt}$

so we have

$\int E. dL = \pi r^2 (\mu_0 n \frac{di}{dt})$

$E. (2\pi r) = \pi r^2 (\mu_0 n \frac{di}{dt})$

$E = \frac{\mu_0 n r}{2} \frac{di}{dt}$

Part a)

At r = 0.500 cm

we have

$E = \frac{4\pi \times 10^{-7} (950) (0.500 \times 10^{-2})}{2}(63)$

$E = 0.188 \times 10^{-3} N/C$

Part b)

At r = 1.00 cm

we have

$E = \frac{4\pi \times 10^{-7} (950) (1.00 \times 10^{-2})}{2}(63)$

$E = 0.376 \times 10^{-3}$ N/C

What comes before Action-reaction?

Anarel [89]

These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

Suppose you must design an experiment to test how a paper airplane's shape affects the distance it will fly. Your plane must fly

Rina8888 [55]

Answer:

Explanation:

Your plane must fly halfway across your classroom to get the best grade. The teacher reminds you to use both imagination and logical reasoning in your design. Write a procedure for an experiment that tests how a paper airplane's shape affects the distance it will fly. Then, describe how you might use both ...
