Since the magnetic field is into the page (as indicated by the dots), and the current is from A to B, the force on section BC will be perpendicular to and out of the page, which is option B.
To determine the direction of the force acting on section BC of the coil, we need to use the right-hand rule for magnetic fields.
With the fingers of your right hand pointing in the direction of the current (from A to B), curl your fingers towards the direction of the magnetic field (from north to south) and your thumb will point in the direction of the force on section BC.
The dimensions of the coil (length and width) are not relevant in determining the direction of the force in this scenario.

Explain how is the voltage across a resistor measured?
Answer:
You take the basic formula of E = I x R, solve for R -> R = E / I. In other words, take the required voltage drop (in volts) and divide by the current (in amps) in the resistor and determine the resistance (R) in ohms.

How are humidity and precipitation related?
A. When humidity is low, the chance of precipitation is high.
b.When humidity is high, the chance of precipitation is high.
c.When humidity is high, the chance of precipitation is low.
d.Changes in humidity do not cause precipitation.
Answer:
Relative humidity depends on the amount moisture actually in the air at some temperature to the amount of moisture that the air can hold.
For instance, at 25 deg C the air has a saturation pressure of 23.76 mm of Hg.
That means that if at that temperature the pressure of the water vapor in the air reaches 23.76 mm Hg then the air is 100% saturated.
I believe the standard air pressure at 25 deg C is 760 mm Hg.
Now if the pressure of the water vapor in the air is 1/2 * 23.76 = 11.88 mm then the air is 50% saturated and the relative hunidity is 50 %.
At 100% relative humidity rain occurs (the air can't hold any more water).
When humidity is high, the chance of precipitation is high. The correct answer is b. When humidity is high, the chance of precipitation is high.
The amount of moisture or water vapor in the air is referred to as humidity. Relative humidity is a common way to measure it since it shows how much moisture the air is holding relative to how much it could contain at a particular temperature.
Any type of water that falls from the atmosphere and makes it to the surface of the Earth is referred to as precipitation. Examples include rain, snow, sleet, and hail.
When humidity levels are high, there is a lot of moisture in the air, which increases the possibility that saturation will occur. Excess water vapor condenses into visible water droplets or ice crystals as the air gets saturated, creating clouds. Condensed moisture in the clouds eventually gains enough weight to return to Earth as precipitation.
Therefore, when humidity is high, the chance of precipitation is high. The correct answer is:
b. When humidity is high, the chance of precipitation is high.

4.72 x 106 m
Answer:
5.17 x 10^5
Explanation
The correct answer is (b) [tex]5.17*10^{5}m[/tex]
Let us consider an object of mass m on the planet Q.
On planet Q, let the acceleration due to gravity be g = 2.24 m/[tex]s^{2}[/tex]
Mass of the planet is M = [tex]8.96*10^{21} kg[/tex]
Let its radius be R
and the universal gravitational constant G = [tex]6.67*10^{-11} m/kg[/tex]
Gravitational Force acting on the object:
[tex]mg=\frac{GMm}{R^{2} }[/tex]
[tex]R=\sqrt{\frac{GM}{g} } \\R=\sqrt{\frac{6.67*10^{-11}*8.96*10^{21} }{2.24} }\\R=5.17*10^{5} m[/tex] is the radius of the planet Q.

Discuss how the motion of the stunt cyclist relates to the forces acting on the stunt cyclist during the collision
Answer:
hello your question is incomplete hence I will give you a general answer on how a stunt cyclist performs his stunts successfully
answer ;
The stunt cyclist trying to perform some sort of stunt with the bicycle will be faced with some forces like the static fiction between the tires of the bicycle and wall and also a centripetal force.
In order to overcome the centripetal force the minimal grip of the bicycle must be equal to the weight and the speed at which the cyclist must go can be represented as :
[tex]V_{min} = \sqrt{\frac{r.g}{u} }[/tex]

Why is the overall charge of the atom neutral or zero?
A. The zero charge on the neutrons in the nucleus create a neutral atom.
B. The number of protons is equal to the number of electrons
C. Equal numbers of neutrons, protons, and electrons work together to keep the charge of the atom neutral or zero.
D. Atoms are not electrical and therefore have no charge.
Answer:
B
Explanation:
this is because the neutrons do not have a charge, the things that have charge in an atom are electrons and protons.
and in the nucleus of an atom, there are protons and neutrons so you can see that A is not the answer
if you see the periodic table, you will know that the number of electrons and protons are equal, so the charges cancel each other out, hence the charge of an atom will be neutral
let me give you a tip which I got from my teacher, never write there is no charge in the atom, this suggests that there is no protons or electrons.
instead, write, the it is neutral

A 2 kg ball is thrown down with 50J of energy from a height of 10m, what is its velocity before it strikes the ground (neglect air resistance)
Answer:
Explanation:
Given the following data;
Mass = 2kg
Energy = 50J
Height = 10m
To find the speed
Kinetic energy can be defined as the energy possessed by a body due to its motion.
K.E = ½mv²
Substituting into the equation, we have;
50 = ½*2*v²
V² = 50
Taking the square root of both sides, we have;
V = 7.07m/s
A cyclist accelerates from 0 m/s to 8 m/s in 3 seconds. What is her acceleration? Is the acceleration higher of another cyclist who accelerates from 0 to 30 m/s in 8 seconds? How do you know?
Answer:
Acceleration of one cyclist=[tex]2.67m/s^2[/tex]
Yes, the acceleration is higher of another cyclist who accelerates from 0 to 30 m/s in 8 seconds.
Explanation:
We are given that
Initial velocity of one cyclist, u=0 m/s
Final velocity of one cyclist, v=8m/s
Time, t=3 s
Initial velocity of another cyclist, u'=0
Final velocity of another cyclist, v'=30m/s
Time, t'=8 s
We know that
Acceleration, [tex]a=\frac{v-u}{t}[/tex]
Using the formula
[tex]a=\frac{8-0}{3}=\frac{8}{3}=2.67m/s^2[/tex]
Acceleration of one cyclist=[tex]2.67m/s^2[/tex]
Acceleration of another cyclist, a'=[tex]\frac{30-0}{8}m/s^2[/tex]
Acceleration of another cyclist, a'=[tex]3.75m/s^2[/tex]
Yes, the acceleration of another cyclist is higher than the cyclist which accelerates from 0m/s to 8m/s.
