A physicist performing a sensitive measurement wants to limit the magnetic force on a moving charge in her equipment to less tha

n 1.00 x 10 -12 N. What is the greatest the charge can be if it moves at a maximum speed of 30.0 m/s in the Earth’s field? You may assume the Earth’s magnetic field is 5.00 x 10 -5 T.

Answer:

Maximum charge will be 6.66\times 10^{-9}C

Explanation:

We have given force ion the moving charge F=10^{-12}N

Maximum speed of the moving charge v = 30 m /sec

Magnetic field B=5\times 10^{-5}T

We have to fond the charge

Force on moving charge is given by

F=qvB

So 10^{-12}=q\times 30\times 5\times 10^{-5}

q=6.66\times 10^{-9}C

Maximum charge will be 6.66\times 10^{-9}C

If you are using a wrench to loosen a very stubborn nut, you can make the job easier by using a "cheater pipe." This is a piece
pentagon [3]

Answer:

Explained

Explanation:

The cheater pipe extends the wrench in  radial direction, providing a larger momentum for the force you exert.

For a given force the torque exerted with the cheater pipe is larger.

Mathematically we can write that

τ = r×F and τ'= r'×F

now since r'> r

⇒ F'>F

During what era did the French and Indian War occur?
Thepotemich [5.8K]
<span>French and Indian War began in 1754 and ended with the Treaty of Paris in 1763. The war provided Great Britain enormous territorial gains in North America, but disputes over subsequent frontier policy and paying the war’s expenses led to colonial discontent, and ultimately to the American Revolution.</span>

What does the area between the line and the x-axis represent on a velocity vs. time graph?
Finger [1]

Answer:

It has been learned in this lesson that the area bounded by the line and the axes of a velocity-time graph is equal to the displacement of an object during that particular time period. ... Once calculated, this area represents the displacement of the object.

10 turns of wire are closely wound around a pencil as shown in the figure. when measured using a scale as shown, the length of t
Mila [183]

Answer:

a. The thickness of the wire is 2.5 mm.

b. The wire is 0.25 cm thick.

Explanation:

Number of turns of the wire = 10

The length of total turns = 25 mm

a. The thickness of the wire can be determined by;

thickness of the wire = \frac{length of total turns}{number of turns}

                           = \frac{25}{10}

                           = 2.5 mm

Therefore, the wire is 2.5 mm thick.

b. To determine the thickness of the wire in centimetre;

10 mm = 1 cm

So that,

2.5 mm = x

x  = \frac{2.5}{10}

   = 0.25 cm

The wire is 0.25 cm thick.
