A motorcyclist is riding along a mountain trail that runs parallel to a road below. In fact the trail is 6 meters above the road. The motorcyclist then notices a flat bed truck directly below moving at the same speed and decides to drive off the trail, without changing speed. Fortunately, the motorcycle safely lands on the flatbed of the truck. What would the outcome have been if the trail was 12 meters above the road, but all other parameters remain the same?
The complete question reads:
A motorcyclist is riding along a mountain trail that runs parallel to a road below. In fact, the trail is 6 meters above the road. The motorcyclist then notices a flatbed truck directly below moving at the same speed and decides to drive off the trail, without changing speed. Fortunately, the motorcycle safely lands on the flatbed of the truck. What would the outcome have been if the trail was 12 meters above the road, but all other parameters remain the same?
a) The motorcycle would land slightly behind the truck.
b) The motorcycle would land in front of the truck.
c) The motorcycle would land on the flatbed of the truck as before.
d) The motorcycle would land several meters behind the truck
Answer:
c) The motorcycle would land on the flatbed of the truck as before.
Explanation:
Note that if the trail was 12 meters above the road, but all other parameters remain the same, it simply means that other parameters like the speed of both the motorcyclist and the flatbed truck are the same.
Also, remember we are told that the mountain trail runs parallel to the road below, thus, there is a greater likelihood that the motorcyclist who has a higher height (to his advantage) could land on the flatbed of the truck.

Tiana jogs 1.5 km along a straight path and then turns and jogs 2.4 km in the opposite direction. She then turns back and jogs 0.7 km in the original direction. Let Tiana's original direction be the positive direction. What are the displacement and distance she jogged?
Answer:
Distance: 4.6km Displacement= -0.2km
Explanation:
Total distance: 1.5+2.4+0.7= 4.6 km
Displacement: 1.5-2.4+0.7= -0.2km
The displacement may also be 0.2km, it just depends on if it wants it negative or not.
Tiana displacement is 0.2 km in the opposite direction, while her distance covered is 4.6 km
Given that Tiana's original direction be the positive direction.
Displacement is a vector quantity. That is, we will consider both the magnitude and direction.
As Tiana jogs 1.5 km along a straight path and then turns and jogs 2.4 km in the opposite direction, Her displacement = 1.5 - 2.4
As She then turns back and jogs 0.7 km in the original direction,
Displacement = 1.5 - 2.4 + 0.7
Displacement = - 0.2 km ( that is, in the opposite direction.)
Distance is a scalar quantity. That is, we will only consider the magnitude.
Tiana total distance = 1.5 + 2.4 + 0.7
Total distance = 4.6 km
Therefore, her displacement is 0.2 km in the opposite direction, while her distance covered is 4.6 km

Four students are each pushing on one side of a box. Mara is pushing to the west, Cindi is pushing to the east, Chris is pushing to the north, and Sammy is pushing to the south. If the box moves to the east, which student does work on the box?
Answer:
cindi
Explanation:
cindi's work done is larger than all the other students combined
If different forces acting on a body from opposite directions, they cancel each other in magnitude. Thus, if any force make a displacement on an object, it said to be work done. Here, Cindi pushes the box to east and if the boxy move to east Cindi done work on the box.
What is work done?Work done in physics is the dot product of force and displacement. Thus when a force results in the displacement of an object the force is said to be work done on the box.
Force, is an external agent acting on a body to change the state of it from rest or motion. Not all force results in work done. But those which make a movement or displacement of an object it is said to be work done.
Here box experience a force exerted from all four directions. If it move to any one direction the force towards that direction will be greater in magnitude. Thus, if the box moves to east, Cindi does work on the box and the force applied by Cindi will be greater than all other force.

A change in the gravitational force acting on an object will affect the object’s
A. Mass
B. Coefficient of static friction
C. Weight
D. Inertia
c. weight.
Explanation:
I had the exact same question
a change in gravitational force affects weight. The correct answer is: c. Weight
The gravitational force is given by the law of universal gravitation
F = [tex]G \frac{M m}{r^2}[/tex]
where F is the force, G the constant of universal attraction, M and m the mass of the two bodies, r the distance between the bodies
In the case that a body is lying on the surface of the planet, the distance is the radius of the planet, in this case the radius of the Earth
r = R_e
F = [tex]G \frac{M m}{R_e^2}[/tex]
For convenience we can define a new variable called acceleration of gravity (g)
g = [tex]G \frac{M}{R_e^2}[/tex]
we substitute
F = g m
This amount is called body weight, so a change in gravitational force creates a change in weight, therefore the correct answer is: C Weight
In conclusion a change in gravitational force affects weight, therefore the correct answer is: c. Weight

A car is accelerated from 40 m/s to 48 m/s in 6.5 seconds. What is the magnitude of the car’s
average acceleration during this period?
Answer:
Explanation:
AVerage acceleration is the cjange in velocity with time
a = v-u/t
v is the final velocity = 48m/s
u is the initial velocity = 40m/s
t is the time = 6.5s
a = 48-40/6.5
a = 8/6.5
a = 1.23m/s²
Hence the magnitude of the car’s average acceleration during this period is 1.23m/s²

Which best describes what occurs when an object takes in a wave as the wave hits it? O transmission O absorption O reflection O refraction
Answer:
Hello there hope you are having a great day! Your answer would most likely be B. Absorption
Explanation:
Absorption is when a wave comes into contact with a medium and causes the medium's molecules to vibrate and move. This vibration absorbs or takes some of the energy away from the wave and less of the energy is reflected. I hope this helps have a blessed day!
When an object takes in a wave as the wave hits it, then absorption occurs. The correct option is B.
What happens when a wave strikes an object?When a wave strikes an object, it can interact with the object in a variety of ways depending on the properties of the wave and the object.
One possibility is that the wave will be reflected by the object, bouncing back in the opposite direction. The amount of reflection that occurs will depend on the angle of incidence, the angle at which the wave strikes the object, and the properties of the object's surface. For example, a smooth, flat surface will reflect more of the wave than a rough, irregular surface.
Another possibility is that the wave will be absorbed by the object, causing the object to vibrate or heat up. The amount of absorption that occurs will depend on the frequency and intensity of the wave, as well as the material properties of the object.
Finally, in some cases, the wave may pass through the object, either partially or completely. This will depend on the material properties of both the wave and the object, as well as the wavelength and intensity of the wave.
The specific outcome of a wave striking an object will depend on a number of factors, including the type of wave, the properties of the object, and the angle and intensity of the wave.
Here in this question,
Absorption occurs when the energy of the wave is transferred to the object, causing it to vibrate or heat up. The amount of absorption that occurs depends on the properties of the wave and the object. For example, a soft, spongy material will absorb more of the wave than a hard, rigid material.
Therefore, When an object takes in a wave as the wave hits it, the best description for what occurs is absorption.
