A magnetic field of 14 x 10^-3 T exists at the corner of a circular coil of radius 20cm having 15

Physics

The current in the coil is 297 A

Explanation:

The magnetic field of a circular coil carrying a current is given by

B=\frac{\mu_0 NI}{2R}

where

\mu_0 =4\pi \cdot 10^{-7} Tm/A is the vacuum permeability

N is the number of turns in the coil

I is the current in the coil

R is the radius of the coil

For the coil in this problem, we have:

B=14\cdot 10^{-3} T

R = 20 cm = 0.20 m

N = 15

Solving the equation for I, we find the current in the coil:

I=\frac{2BR}{\mu_0 N}=\frac{2(14\cdot 10^{-3})(0.20)}{(4\pi \cdot 10^{-7})(15)}=297 A

What type of galaxy is M82 based on its appearance in the visible-light view?
SSSSS [86.1K]
<h2>Answer: irregular</h2>

According to Hubble  galaxies are classified into elliptical, spiral and irregular.

 

It should be noted this classification is based only on the visual appearance of the galaxy, and does not take into account other aspects, such as the rate of star formation or the activity of the galactic nucleus.  

The classification is as follows:  

1. Elliptical galaxies: Their main characteristic is that the concentration of stars decreases from the nucleus, which is small and very bright, towards its edges. In addition, they contain a large population of old stars, usually little gas and dust, and some newly formed stars.  

2. Spiral galaxies: They have the shape of flattened disks containing some old stars and also a large population of young stars, enough gas and dust, and molecular clouds that are the birthplace of the stars.  

3. Irregular Galaxies:  Galaxies that do not have well-defined structure and symmetry.  

In this context, galaxy M82 does not match with the first two types of galaxies, because it has not a defined shape.

Therefore, M82 is an  irregular galaxy.

Is it possible for an object that has a constant negative acceleration to change the direction in which it is moving? Explain wh
lozanna [386]
Yes! I think there are two ways you could go with this answer: 1) Acceleration is the change in velocity over time, it can be negative or positive. If you have an object that is already moving forwards in a straight line and give it a constant negative acceleration, it will slow down and then start going in reverse. 2)Velocity is a vector, meaning it has both magnitude and direction. In the example above, the acceleration is due to a change in magnitude, or speed (from +ve to -ve) but not a change in direction. Something that has constant speed but is changing direction is also accelerating (like something that is orbiting). You could use the earth as an example, which is constantly accelerating due to moving in a circle around the sun. At any time in the year you can say that in half a year's time the earth's direction will be reversed.
