A current in a wire increases from 2 a to 6 a. how will the magnetic field 0.01 m from the wire change? it increases to four times its original value. it increases to three times its original value. it decreases to one-fourth its original value. it decreases to one-third its original value.
Answer:
It increases to three times it's original value.
Explanation:
B
Hi there!
Recall the equation for the magnetic field of a wire (assuming infinite):
[tex]B = \frac{\mu _0 i_{encl}}{2\pi r}[/tex]
B = Magnetic field (T)
μ₀ = Permeability of Free Space (Tm/A)
i = enclosed current (A)
r = distance from wire (m)
From the equation, we can see that there is a DIRECT relationship between the current and the magnetic field.
Therefore, if the current is increased by a factor of 3, the FIELD will also be increased by a factor of three.

Why is glass a good insulator? (1 point)
O The atoms in glass hold on tightly to their positively charged particles.
O The atoms in glass do not hold on tightly to their positivelycharged particles.
The atoms in glass do not hold on
Glass is known to be a good insulator because atoms in glass hold on tightly to their positively charged particles.
What is an insulator?Insulators are those substances that do not conduct heat or electricity like their conductor counterparts.
Conduction of electric charges is as a result of the free flow of electrons in the atom of the substance.
Hence, a good insulator holds on tightly to its electrons and prevent them from flowing freely to conduct electric charges.
Therefore, Glass is known to be a good insulator because atoms in glass hold on tightly to their positively charged particles.

The best answer is true. Yes, control rods are used to slow down the reaction in the reactor core when the core becomes too hot.
What is a nuclear reactor?A nuclear reactor, often known as an atomic pile, is a device that initiates and controls nuclear chain reactions or nuclear fusion processes.
Nuclear reactors are used in nuclear power plants to generate energy as well as in nuclear marine propulsion.
Control rods are employed in nuclear reactors because the processes that occur in a nuclear reactor are very exothermic.
As a result, when these control rods are infused into a nuclear reactor, they absorb neutrons and aid in the management of the chain reaction. As a result, the rate of the chain reaction is brought under control.
As a result, we may infer that the statement control rods are employed to slow down the reaction in the reactor core when it gets too hot is correct.
Hence the best answer is true. Yes, control rods are used to slow down the reaction in the reactor core when the core becomes too hot.

A car travels at an average speed of 60 km/h for 15 minutes.
How far does the car travel in 15 minutes?
D
900 km
C 240 km
4.0 km
A
В B 15 km
Answer:
(Option B)The car travels 15km in 15 minutes.
Explanation:
Notice that the speed is written using units of km/h and the time is written using units of minutes.
Convert the time interval to hours. Remember that 1 hour equals 60 minutes:
15 min = 15 min × [tex]\frac{1h}{60~min}=0.25h[/tex]
The distance d that a particle travels during a time t if it moves at an average speed v is given by the formula:
d = v · t
Replace v=60km/h and t=0.25h to find the distance traveled by car:
[tex]d=(60\frac{km}{h}) ~x~(0.25h)=15km[/tex]
Therefore, the car travels 15km in 15 minutes.

A 10-A current is maintained in a simple circuit with atotal resistance of 209 ohm. What net charge passes through any point in a circuit during a 1-minute interval?
Answer:
I = Q / t definition of current I
Q = i t = 10 Coul/sec * 60 sec = 600 Coul
A 10-A current is maintained in a simple circuit with a total resistance of 209 ohms, then the net charge passes through any point in a circuit during a 1-minute interval would be 6000 Coulombs.
What is an electric charge?Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge. You can have a positive or negative electric charge.
Electric current is defined as the charge per unit of time.
The mathematical relation between current and the electric charge
I =Q/T
Let us first convert the time period of minutes into seconds
1 min = 60 seconds
10 min = 10*60 seconds
=600 seconds
Q = I*t
=10*600
=6000 Amperes
Thus, the net charge that passes through any point in a circuit during a 1-minute interval would be 6000 Amperes.

what are seismic waves?
The seismic waves can be defined as the waves full of energy that travel through the Earth's layer, these waves are the result of earthquake.
They can further be divided into two types body wave and surface waves. The body waves travel in the interior of the Earth and the surface waves travel at the surface of the Earth.
The seismic waves can have an amplitude of few centimeters in large earthquake. They travel slower as compared to the body waves.

At what distance does the electric field produced by a charge of -15 μc have a magnitude equal to 8. 7×104n/c?
Answer:
we'll use the electric field formula. ı wrote the formula in the photo.
Explanation:
The electric field formula is obtained by multiplying force and charge. When you apply this process I mentioned, you will find an electric field. then it is to write the given values and find the result. achievements.
At the distance for which the electric field produced by a charge of -15 μc have a magnitude equal to 8. 7×104n/c is 3.93 meters.
What is electric force?Electric force is the force of attraction of repulsion between two bodies.
According to the Coulombs law, the force of attraction of repulsion between charged two bodies is directly proportional to the product of charges of them and inversely proportional to the square of distance between them.
It can be given as,
[tex]F=k\dfrac{Q}{r^2}[/tex]
Here, (k) is the coulombs constant, (Q) is the charges and (r) is the distance between the two charges.
The charge of -15 μc have a magnitude equal to 8. 7×104n/c. Put this value in the above formula,
[tex]8.7\times10^4=(8.98\times10^{9})\dfrac{15\times10^{-6}}{r^2}\\r=3.93\rm\; m[/tex]
