Many people love roller coasters. Some people call them scream machines. They agree that
riding a roller coaster is a thrilling experience. What you may not realize while you are going 60 miles an hour is that a roller coaster has no
engine. You are not being propelled around the track by a motor or pulled by anything. A roller coaster moves on its own. How do you think that
can happen?
Answer:
There is some sort of "rollers" on the trail part that is used to make the roller coaster move when it is going up. Then because of that, the speed gets quicker when it drops down, so then it could move for a longer time until it reaches the next arch.

Total distance does not take into account the direction of the object, but displacement always includes direction.
Question 1 options:
True
False
Answer: True
Explanation:
Distance is a scalar, which means it has no direction. It is the sum of the entire path traveled.
Displacement is a vector, which means it does have direction. It is the shortest path from the start to the end. It is defined as [tex]x_f-x_i[/tex].
Why does the layer of glass in a solar cell need an antireflective coating?
A. To maximize the energy absorbed by the solar cell
B. To help the cell conduct the charge that is produced
C. To give the layer a negative charge
D. To give the layer a positive charge
the answer is A
Answer:
The Anti Reflective Coating on a solar cells helps to increase the amount of light absorbed into the cell. This anti reflective coating is very much needed as the reflection of a bare silicon solar cells is over 30%. For the thin AR Coating, silicon nitride or titanium oxide is used.

What is the weight of a dog that has a mass of 47.0 kg?
Answer:
while we often confuse mass with weight, 47 kg is 47 x 9.8 = 460.6 Newtons. 9.8 is acceleration of gravity in m/sec/sec
What work is done when a person lifts a 1.6 kg package and places it on a shelf 2.4m high?
Answer:
Explanation:
Work is the dot product of force and distance
[tex]W = F*d=Fd*\cos(theta)[/tex]
The only force acting on this box is the force of gravity (weight) which is mass*gravity
F = (1.6)(9.8) = 15.68N
The angle is the angle between the force and distance. In this case it is zero, therefore cos(Ф) = 1
[tex]W=15.68*2.4=37.6J[/tex]

Heart Rate During Aerobic Activity?
Answer:
It is recommended that you exercise within 55 to 85 percent of your maximum heart rate for at least 20 to 30 minutes to get the best results from aerobic exercise. The MHR (roughly calculated as 220 minus your age) is the upper limit of what your cardiovascular system can handle during physical activity.

Determine the stopping location of the prize wheel. At this moment it is centered on the number 5. It is spinning with an energy of 6.19 J. It is slowing at a rate of 1.800 rad/s/s.
The disk is made from a wood with a density of 478.0 kg/m^3. The disk is 29.0 mm thick and has a radius of 33.0 cm.
Predict the angular displacement it will go through and predict the number on which the wheel will stop. To be safe, you will also get one number the right and to the left of the number you chose.
The wheel will spin clockwise. The wheel goes from 1 to 36.
Answer:
Thanks for the 50 points. Answer eill be always 29.0m

A man driving a car sees a deer crossing the road and brakes the car with a force of 100 N. The car stops after traveling 5m. What is the work done on the car?
Answer:
Workdone = 500Nm
Explanation:
Given the following data;
Force = 100N
Distance = 5m
To find the workdone;
Workdone is given by the formula;
[tex] Workdone = force * distance[/tex]
Substituting into the equation, we have
[tex] Workdone = 100 * 5 [/tex]
Workdone = 500Nm
An object moving with a speed of 35 m/a and has a kinetic energy of 1500j, what is the mass of the object
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
Hope it will help :)
How does Earth's movement affect how the Sun is seen? The Sun is stationary, but Earth's rotation makes it appear to move east to west across the sky. Earth's rotation around the Sun makes the Sun appear to move across the sky every 365 days. The Sun and Earth move around each other, so the Sun moves east to west across the sky. The Sun is stationary, but Earth's clockwise rotation makes it appear to move west to east across the sky.
Answer:
The manner in which the Earth's movement affect how the Sun is seen is;
The Sun is stationary, but Earth's rotation makes it appear to move East to West across the sky
Explanation:
The Earth's movement affect the way the Sun is seen
The Sun appears to rise in the Eastern part of the sky and continues in motion till the it sets at the Western part of the sky
However, the Sun does not actually move relative to the Earth as seen in the sky. The observed motion of the Sun is due to the counterclockwise rotation of the Earth about its axis
Therefore, the Earth's movement affect the way the Sun is seen by making the Sun appear to move across the sky from East to West
Answer:
The sun stays still but the rotation of the earth makes it look like it goes east to west.

the law of inertia states that an object in motion will stay in motion, and an object at rest will stay in rest unless acted upon by an unbalanced force which law of motion is this describing
Answer:
newton's first law of motion
Explanation:
this is because newton's first law of motion states that every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it so...
isn't this similar to the law of inertia?
yes it is
