A 7.12 µC charge is moving at one half the speed of light perpendicular to a magnetic field of 4.02 mT. How large is the force on the charge?


A.) 4.29 N


B.) 32.90 x 10^(1) N


C.) 4.29 x 10^(12) N


D.) 1.00 x 10^(16) N

Answers

Answer 1

Answer:

The correct option is A: 4.29 N.

Step-by-step explanation:

The magnetic force is given by:

[tex] F = qv\times B = qvBsin(\theta) [/tex]

Where:

q: is the charge = 7.12x10⁻⁶ C

v: is the speed = c/2 = 1.5x10⁸ m/s

B: is the magnetic field = 4.02x10⁻³ T

θ: is the angle = 90° (the speed is perpendicular to the magnetic field)

Hence, the force on the charge is:

[tex]F = qvBsin(90) = 7.12 \cdot 10^{-6} C*1.5 \cdot 10^{8} m/s*4.02 \cdot 10^{-3} T = 4.29 N[/tex]

Therefore, the correct option is A: 4.29 N.

I hope it helps you!

How many quarts are in 10 cups​

Answers

Answer:

There's 2.5

Step-by-step explanation:

4 cups is equal to 1 quart

So that means 8 cups is equal to 2 quarts

If we add 2 more cups then we would add 0.5 more quarts.

This means that 10 cups is 2.5 quarts.

Answer:

2.5 quarts

Step-by-step explanation:

since there are 0.25 quarts in one cup. you have to multiply 2.5 by 10. hope this helps*

Two planes A and B start from the same place and move in different directions making an angle of 50° between them the speed of plane A is 200 mph and the speed of plane B is 300 mph the two planes are blank miles apart after one hour?

Answers

Answer:

The distance between them is 230.65 miles

Step-by-step explanation:

Here we use the Cosine formula

[tex]a^2 = b^2 + c^2 - 2bc\ cos\ A\\\\a^2 = 200^2 + 300^2 - 2\times 200\times 300cos50^{\circ}\\\\= 40,000 + 90,000 - 120,000cos50^{\circ}\\\\= 130,000 - 120,000 \times 0.64\\\\= 130,000 - 76,800\\\\a^2= 53,200\\\\a = \sqrt{53,200} \\\\= 230.65\ miles\ per\ hour[/tex]

Now the distance for one hour is

= 230.65 ÷ 1

= 230.65 miles

if a loan is taken out for $991 at 3% and cost 267.57 dollars how long was the loan for

Answers

Answer:

9 years.

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

t = 267.57 / ( 991 × 0.03 ) = 9

t = 9 years

The time required to

accumulate simple interest of $ 267.57

from a principal of $ 991.00

at an interest rate of 3% per year

is 9 years.

Answer:

x = 26.4

Step-by-step explanation:

Here, we want to get the value of x

To get this, we are to use the appropriate trigonometric ratio

From the question, we have the opposite and the adjacent

The trigonometric ratio to use in this case is the tangent

Mathematically;

Tan 53 = 35/x

x = 35/tan 53

x = 26.37

Look below!

Step-by-step explanation:

Angle A = 180-47 = 133

Angle B = 180-32-Angle A = 180-32-47 = 101

Angle D = 90-32 = 58

Angle C = 180-47-58 = 75

Hope I helped!

Answer:

A=133 ,B=15, C=75  D= 58

Step-by-step explanation:

Angle 32, d, and right angle add up to 180. So 180=32+90+x. Then x = 58 (D). The all 3 angles in the triangle add up too 180 so 180=47+58+x. x=75 (C). The 47 and a equal to 180 degrees. 180-47=133. The 133+32+x=180. x=15 (B).

E 50°, 509,80"

Answers

Answer:A

Step-by-step explanation:

Interior angles of a triangle ALWAYS have to be equal to 180

The sum of A is 180, however, those angles wont work because they have to be more close to eachother for it to be possible

The Triangle Inequality Theorem states the longest side must be shorter than the sum of the other 2 sides

E since the sum of interior angles for a triangle is equal to 180 degrees.

What are polygons?

A polygon is often a plane figure in geometry that is enclosed by a closed chain made up of a finite number of straight-line segments that end in a loop. The spots where two of these segments meet are referred to as the polygon's vertices (plural: vertices) or corners. These segments are known as its edges or sides.

Given a shape,

the shape is a polygon,

to name a polygon first count the number of sides of the figure,

as we count there are 6 sides for the shape,

There are some specific names for the shapes according to their number of sides, like

Number of Sides Name          

3                      Triangle                    

4                 Quadrilateral

5                    Pentagon

6                     Hexagon

The name for the shape is Hexagon.

Hence the name of the figure is Hexagon.
