A conducting coil of 1850 turns is connected to a galvanometer, and the total resistance of the circuit is 30 Ω. The area of each turn is 4.00 × 10-4 m2. This coil is moved from a region where the magnetic field is zero into a region where it is nonzero, the normal to the coil being kept parallel to the magnetic field. The amount of charge that is induced to flow around the circuit is measured to be 8.0 × 10-3 C. Find the magnitude of the magnetic field.

Answers

Answer:

0.324 T

Explanation:

Parameters given:

Number of turns, N = 1850

Resistance, R = 30Ω

Area of each turn, A = $4.00 * 10^(-4) m^2$

Charge in the circuit, q = $8.0 * 10^(-3) C$

The induced EMF in the coil is given as:

$V = (-NBA)/(t)$

EMF is also given in terms of current, I, and resistance, R, as:

V = IR = $(-NBA)/(t)$

=> $I*R*t = -NBA$

Charge, q, is the product of current and time. Hence:

It = q

=> $q*R = -NBA$

Hence, magnetic field, B, will be:

$B = (qR)/(-NA)$

$B = (8 * 10^(-3) * 30)/(-1850 * 4 * 10^(-4)) \n\n\nB = -0.324 T$

The magnitude of magnetic field, |B| will be |-0.324| = 0.324 T

Trumpeter A holds a B-flat note on the trumpet for a long time. Person C is running towards the trumpeter at a constant velocity. Person B is running away from the trumpeter at the same rate. Person D is standing still the whole time.Which person hears a frequency that is lower than the B-flat?
A) Person A
B) Person B
C) Person C
D) Person D

Answers

The person running towards the trumpet, Mr. C,
hears a higher frequency.

The person running away from the trumpet, Mrs. B,
hears a lower frequency.

The trumpeter, Mr. A, and the person who is just standing still
and listening, Miss D, both hears the beautiful perfect B-flat.

On a velocity time graph like this one, the slope tells you the ______ of the object.

Answers

Answer:

On a velocity time graph like this one, the slope tells you the acceleration of object.

Explanation:

On a velocity time graph, velocity is on y-axis while time on x-axis.
Slope on graph shows the change in velocity with time which is equal to the acceleration of object.

Acceleration

On a velocity time graph, the y-axis is velocity, and the x-axis is time. So the slope is the change in velocity for every unit of change in time.

acceleration- the rate of change of velocity per unit of time.

hope this helps :)

Within a single use of the scientific method, which of the following steps can only be performed afterdata is collected?
A. Controls and variables are chosen.
B. The initial experiment is designed.
C. The initial hypothesis is formed.
D. Conclusions are drawn.

Answers

Within a single use of the scientific method, the step which would be performed after we collect data, would be the drawing of a conclusion out of the answers that you've presented - D.

It is usually the case that you first have to analyze the data after you've gather it and then you base your conclusions on it. This isn't, however, always the case.

Which of these statements best describes a similarity between asteroids and comets? A) Both consist of gases
B) Both are dwarf planets
C) Both liquefy due to heat
D) Both orbit around the sun

Answers

Answer:

D) Both orbit around the sun

Explanation:

Asteroids are rocky bodies having irregular shape and of irregular size. Asteroids are revolve around the sun in elliptical paths. Most asteroids are found in the asteroid belt between orbits of Mars and Jupiter. Ceres is the largest asteroid. Since, it is round in shape also, so it is a dwarf planet.

Comets are composed of rock, dust, ice and frozen gases. Comets lie in Kuiper belt and Oort cloud. Comets liquefy due to heat. Comets orbit the sun in elliptical paths. Comets in Kuiper belt have smaller periods than comets found in the Oort cloud.

Thus, the similarity between asteroids and comets is both orbit around the sun.

Final answer:

Asteroids and comets, both types of 'small bodies' in the solar system, share a similarity in that they both orbit around the sun. However, their orbits differ as asteroids tend to have more circular orbits while comets have more elliptical ones. The correct option is D.

Explanation:

The best statement that describes a similarity between asteroidsandcomets is 'Both orbit around the sun'. An asteroid and a comet are both types of 'small bodies' in the solar system, and they both orbit the sun, although their paths, called orbits, are different. Basically, asteroids tend to have more circular orbits while comets have more ellipticalones. Also, unlike the first three options, option D is the only one that is correct for both asteroids and comets. Neither asteroids nor comets are made mostly of gas (option A), are considered dwarf planets (option B), or liquefied due to heat (option C).

A balloon drifts 140m toward the west in 45s ; then the wind suddenly changes and the balloon flies 90m toward the east in the next 25s. What distance did it travel during the first 45s?

Answers

Answer: 140 m

Explanation:

Let's begin by stating clear that motiont is the change of position of a body at a certain time. So, during this motion, the balloon will have a trajectory and a displacement, being both different:

The trajectory is the path followed by the body, the distance it travelled (is a scalar quantity).

The displacement is the distance in a straight line between the initial and final position (is a vector quantity).

So, according to this, the distance the balloon traveled during the first 45 s (its trajectory) is 140 m.

But, if we talk about displacement, we have to draw a straight line between the initial position of the balloon (point 0) to its final position (point 90 m). Being its displacement 95 m.
