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!

Answer:
d. both b and c are not functions, and a is just a chart, not a function.
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?
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
f(x) = -x² + x + 14
Find f (2)
Answer:
Step-by-step explanation:
f(2) = -2^2 + 2 + 14 = -4 + 2 + 14 = 12
Answer:
f(2) = 20
Step-by-step explanation:
f(x) = -x^2 + x + 14
f(2) = (2)^2 + (2) + 14
f(2) = 4 + 2 + 14
f(2) = 20

if a loan is taken out for $991 at 3% and cost 267.57 dollars how long was the loan for
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.
£16.80 in the ratio 2:1
Answer:
1u--> 5.60
2u--> 11.20
Step-by-step explanation:
3u--> 16.80
1u--> 5.60
2u--> 11.20
£16.80 in the ratio 2 : 1
add both sides of the ratio together to get 3
now divide £16.80 by 3 to get £5.60

Answer:
the cube is bc 6 times 5 is 30 and the triangle is 2 because its the same length as the height
Step-by-step explanation:
Which does NOT represent the interior angle measures of a triangle?
O A. 5°, 75°. 100°
B. 10°,80°, 90°
OC. 20°, 60°, 100
O D. 45°, 45°, 45.
ос
E 50°, 509,80"
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

Answer:
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).
A paperweight in the shape of a rectangular prism is shown: A right rectangular prism is shown with length 10 cm, width 4 cm, and height 4 cm. If a cross section of the paperweight is cut diagonal to the base, which shape describes the cross section?
Answer:
Square
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE FIQURE OF THE QUESTION
✓We were given the dimension of the rectangular prism as 10cm × 4cm × 4cm,
✓The cross section of the paperweight can be cut into half to it's base. Then the new dimension will be 4cm × 4cm which is a quadrilateral.
✓ Then width= 4cm, and height=4 cm are of the same values, hence the shape it forms is a SQUARE. and also the their angles is 90° each.

The name of the shape in the figure is a hexagon.
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.

Find the value of x. Round your answer to the nearest tenth.
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
which is 26.4
Someone pleaseee help me on this :( what is the slope of the line that contains these points.
Answer:
6/1
Step-by-step explanation:
the reason is because the x is increasing by 1 which is the denominator, and the y is also increasing by 6 which is the numerator. if you were to imagine those lines on a graph you would get a straight line and use rise over run to see that the slop is in fact 6/1
How many quarts are in 10 cups
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*
