Answer:

32.5

Explanation:

Choose the normal force acting between the object and the ground. Let's assume a normal force of 250 N .

Determine the friction coefficient. ...

Multiply these values by each other: (250 N) * 0.13 = 32.5 N .

You just found the force of friction!

Answer:

Option A is correct

Explanation:

Direction of spin can be measured because of the behaviours of the particle as it goes through a magnetic field and the size of the spin is dependant on type of particle.

Producing a current by moving a wire through a magnetic field is called “BLANK” induction
NeX [460]
Producing a current by moving a wire through a magnetic field is called ELECTROMAGNETIC INDUCTION.
Electromagnetic induction refers to the production of an electromotive force across an electrical conductor in a changing magnetic field. The process was discovered by Micheal Faraday in 1831.

Which of the following values represents an index of refraction of an actual material?
serg [7]

Sadly, we're forced to answer the question without the benefit of the
list of choices, which, for some reason, you decided not to let us see.

Index of refraction of a substance =

               (speed of light in vacuum) / (speed of light in the substance).

Any number greater than  ' 1 ' can be an index of refraction.  A number
less than ' 1 ' can't be . . . that would be saying that the speed of light
in this substance is greater than the speed of light in vacuum.

It is desired to construct a solenoid that will have a resistance of 4.10 Ω (at 20°C) and produce a magnetic field of 4.00 ✕ 10^
Nikolay [14]

Answer:

Part a)

N = 754 turns

Part b)

L = 0.376 m

Explanation:

Resistance of the solenoid is given as

R = 4.10 ohm

now we have

R = \rho \frac{L}{A}

here we know that

\rho = 1.7 \times 10^{-8} ohm-m

A = \pi r^2 = \pi (\frac{0.5 \times 10^{-3}}{2})^2

A = 1.96 \times 10^{-7} m^2

now from above formula

4.10 = (1.7 \times 10^{-8})\frac{L}{1.96 \times 10^{-7}}

L = 47.35 m

Part a)

now we know that it is wounded over the solenoid

so here we can say

N(2\pi R) = L

N(2 \pi (0.01)) = 47.35

N = 754 turns

Part b)

now length of solenoid is given as

L = N(diameter\: of\: the\: wire)

L = 754(0.5 \times 10^{-3})

L = 0.376 m
