Why does the North star not move but the other stars move
Answers
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
An object moving with a speed of 35 m/a and has a kinetic energy of 1500j, what is the mass of the object
Answers
Explanation:
Speed or velocity (V) = 35 m/s
Kinetic energy (K. E) = 1500 Joule
mass (m) = ?
We know
K.E = 1/2 * m * v²
1500 = 1/2 * m * 35²
1500 * 2 = 1225m
m = 3000 / 1225
m = 2.45 kg
The mass of the object is 2.45 kg

Explain the challenges in developing an accurate rating system for earthquakes. What kinds of variables are there?
Answers
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.

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
Answers
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.

A construction worker pushes a wheelbarrow 15 m with a horizontal force of 17 N. How much work is done by the worker on the object?
Answers
Answer:
The work done by the worker on the object is 255 J
Explanation:
Work is defined as the force that is applied on a body to move it from one point to another.
When a net force is applied to the body or a system and this produces displacement, then that force is said to perform mechanical work. This work can be positive if the system gains energy or negative if the system loses energy.
In the International System of Units, work is measured in Joule. Joule is equivalent to Newton per meter.
The work is equal to the product of the force by the distance and by the cosine of the angle that exists between the direction of the force and the direction that travels the point or the object that moves.
In this case, the angle between the force and the displacement is 0 degrees. Then the cosine of 0 degrees will have a value of one. So work is calculated as the multiplication between force and distance:
W= 17 N* 15 m
Solving:
W= 255 J
The work done by the worker on the object is 255 J

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.
Answers
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.

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
Answers
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

Discuss a time when you made an impulsive decision. What was the decision? Why did you make your decision
impulsively? What were the consequences of the decision? If you had the decision to make all over again, how would you
change your decision?
Answers
ANSWER 2: The decision was taken because the car was limited and it was a huge stock clearance from the dealer's end after which the car's production was stopped and it won't be available. The car being my father's favorite, I wanted to gift it to my dad.
ANSWER 3: The consequence of the decision was I had to get loan from finance company with a tenure of 5 years. The car was well out of my budget. I made a down payment of whatever savings and I got my loan.
ANSWER 4: If the decision was to made all over again, I would prefer to calculate my finance first. I would prefer a used car to buy for me or my dad rather than running for last minute deals from the dealers. The used car will be well within my budget and would also be offering the same features as the new car would have been.

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???
Answers
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.
