What is the size of the force acting on a copper wire with a magnetic flux density of 3.6 x 10 2 T acting at
right angles to the wire of length 19 m and current of 0.043 A? Round your answer to 2 significant
figures.
Answer:
2900 N
Explanation:
We are given;
Magnetic flux density; B = 3.6 × 10² T
Length of wire; L = 19 m
Current; I = 0.043 A
Formula for force in this regards is;
F = BIL
Where;
B is Magnetic flux density
I is current
L is length
Thus;
F = 3.6 × 10² × 0.043 × 19
F = 2941.2
To 2 significant figures gives;
F = 2900 N

Naoki's bicycle has a mass of 9 kg. If Naoki sits on her bicycle and starts pedaling with a force of 107.2 N, causing an acceleration of 1.6 m/s2, what is Naoki's mass?
A.
69 kg
B.
58 kg
C.
67 kg
D.
14 kg
PLZ HELP ME........thank you
Answer:
Explanation:
F = ma
m = F/a
m = 107.2/1.6 = 67 kg
so Naoki's mass must be the total mass - mass of the bike
so her mass is 67 - 9 = 58 kg...B

Why did you need to heat the water to make the nectar?
A. Heating the water increases the solubility of the sugar.
B. Heating the water decreases the melting point of the sugar.
C. Heating the water increases the boiling point of the sugar.
D. Heating the water increases the particle motion of the sugar.
Answer:
D
Explanation:
Heating up the solvent gives the molecules more kinetic energy. The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves.

Why does the North star not move but the other stars move
Answer:
it's the star in the center of the star field
Explanation:
Why Doesn't Polaris Move? Polaris is very distant from Earth, and located in a position very near Earth's north celestial pole. ... Polaris is the star in the center of the star field; it shows essentially no movement. Earth's axis points almost directly to Polaris, so this star is observed to show the least movement

Explain the challenges in developing an accurate rating system for earthquakes. What kinds of variables are there?
Answer:
In turn, the main factors affecting earthquake shaking intensity are earthquake depth, proximity to the fault, the underlying soil, and building characteristics—particularly height. Let's take a look at the latter two (soil and buildings) and how they interact.
The challenge in developing an accurate rating system for earthquakes is due to complicated relationship between variables such as magnitude and intensity of earthquake.
Earthquakes are associated with magnitude and intensity.
The challenge in developing an accurate rating system for earthquake is due to complicated relationship and dependency between the magnitude and intensity of the earthquake.
Intensity of earthquake is the observed effects resulting from the earthquake such as; shaking of buildings, people etc. This intensity of the earthquake depends on the location of the observer with respect to earthquake epicenter.The magnitude of the earthquake relates to the amount of energy released during the earthquake.Thus, the challenge in developing an accurate rating system for earthquakes is due to complicated relationship between variables such as magnitude and intensity of earthquake.

How does density affect refraction?
Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from the air through a diamond.
Answer:
The density of a material affects the speed that a wave will be transmitted through it. In general, the denser the transparent material, the more slowly light travels through it.
A spring is compressed between two blocks, one with a mass of 2 kg and the other with a mass of 3 kg. If the 2 kg block has an average acceleration of 6 m/s^2 when the spring acts on it, what will be the average acceleration of the 3 kg block???
Answer:
2=6
3=9
Explanation:
I think this is right I'm not sure but I have done problems like this and did based on what I remember.
The average acceleration of the 3 kg block is 4 m/s².
The given parameters;
mass of first block = 2 kgmass of second block = 3 kgacceleration of the first block, = 6 m/s/sAccording to Newton's third law of motion, action and reaction are equal and opposite.
The force exerted on both blocks are equal and opposite.
[tex]F = ma\\\\m_1 a_1 = m_2a_2\\\\a_2 = \frac{m_1 a_1}{m_2}\\\\a _2 = \frac{2\times 6}{3} \\\\a_2 = 4 \ m/s^2[/tex]
Thus, the average acceleration of the 3 kg block is 4 m/s².

Moving a spring toy up and down will create what kind of disturbance?
parallel to the wave motion
in a circular motion
in the same direction as the wave motion
perpedicular to the wave motion
Answer:
Perpindicular to the wave motion.
Explanation:
Moving a spring toy up and down will create a disturbance in the same direction as the wave motion.
We can classify waves by the direction of wave motion in which case waves are classified into;
Transverse wavesLongitudinal wavesLongitudinal waves are waves in which the direction of disturbance is in the same direction as the wave motion. The wave along a spring is a longitudinal wave therefore; moving a spring toy up and down will create a disturbance in the same direction as the wave motion.

How does the intensity of a sound wave change if the distance from the source increases by a factor of 2?
If the distance from the source is doubled or increased by a factor of 2, then the intensity is quartered decreased by a factor of 4.
What is the intensity of sound wave?A sound wave's intensity is inversely related to density and speed and proportionate to the change in pressure squared.
The region that the sound waves cover grows as one gets farther from the source of the sound. The intensity and loudness of the sound are reduced because the same quantity of energy is dispersed over a larger region.
Inversely proportional to the square of the source's distance, the intensity varies.
Therefore, if the distance from the source is doubled or multiplied by a factor of 2, the intensity is reduced by a factor of 4 and then by a fourth.
When a time difference is twice, intensity is reduced by a factor of 4 each time.
