Answer:
0.324 T
Explanation:
Parameters given:
Number of turns, N = 1850
Resistance, R = 30Ω
Area of each turn, A =
Charge in the circuit, q =
The induced EMF in the coil is given as:
EMF is also given in terms of current, I, and resistance, R, as:
V = IR =
=>
Charge, q, is the product of current and time. Hence:
It = q
=>
Hence, magnetic field, B, will be:
The magnitude of magnetic field, |B| will be |-0.324| = 0.324 T
A) Person A
B) Person B
C) Person C
D) Person D
Answer:B
Explanation:Making fast and simple :)
On a velocity time graph like this one, the slope tells you the acceleration of object.
Explanation:
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 :)
A. Controls and variables are chosen.
B. The initial experiment is designed.
C. The initial hypothesis is formed.
D. Conclusions are drawn.
B) Both are dwarf planets
C) Both liquefy due to heat
D) Both orbit around the sun
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.
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.
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).

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.
