Instrument locations around Earth record seismic wave activity during an earthquake. The epicenter of the earthquake and locations of 4 instruments stations around Earth are shown. Which stations will record fewer waves than the others?
Answers
Answer:
explanations below
Explanation:
From the attached document, it can be seen that Stations 2 and 3 are further away from the epicenter unlike stations 1 and 4. Stations 2 and 3 are likely going to record fewer waves than the others because as the wave travel such distances, part of it are bent by the earth’s interior and some of the materials in earth also reflect some of the waves.

Two masses are placed close to each other. How will the gravitational force acting on the masses change if the distance between the two masses is doubled?
Answers
Answer:
If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.The snow fell on me is my excuse so my mom won’t know that I’m getting bullied

A student moves a box across the floor by exerting 56.7 N of force and doing 195 J of
work on the box. How far does the student move the box?
A.3.4 m
B. 11,056 m
C.138 m
D.0.29 m
Answers
Answer:
A. 3.4 m
Explanation:
Given the following data;
Force = 56.7N
Workdone = 195J
To find the distance
Workdone is given by the formula;
[tex] Workdone = force * distance[/tex]
Making "distance" the subject of formula, we have;
[tex] Distance = \frac {workdone}{force} [/tex]
Substituting into the equation, we have;
[tex] Distance = \frac {195}{56.7} [/tex]
Distance = 3.4 meters.

You have a 100 N object with a normal force of 100 N. You apply a 50 N push to the right, but a friend is hiding on the other side of the object and is also pushing with a force of 60 N. What is the net force on the object?
Answers
Answer:
100.49N
Explanation:
First we must know that the normal force acts in the vertical direction;
The force required to push to the right and left acts in the horizontal direction;
Sum of force along the horizontal Fx = 50N - 60 N = -10N
Force along the vertical Fy = 100N
The net force on the object is calculated as;
F = √(Fx)² + (Fy)²
F = √(-10)² + (100)²
F = √100 + 10000
F = √10,100
F = 100.49N
Hence the net force on the object is 100.49N
What has more energy a 2 kg mass at 10 m/s or a 2 kg mass 5 m above the ground
Answers
Answer:
Both have same energy
Explanation:
Given:
Sample 1
Mass m = 2 kg
Velocity v = 10 m/s
Sample 2
Mass m = 2 kg
Height h = 5 m
Assume g = 10 m/s²
Find:
What has more energy
Computation:
In sample 1
Ke = 1/2(m)(v)²
Ke = 1/2(2)(10)²
Ke = 100 joule
In sample 2
Pe = mgh
Pe = (2)(10)(5)
Pe = 100 joules
Both have same energy
An object is moving east, and its velocity changes from 66 mvs to 26 mvs in 10 seconds. Which describes the
acceleration?
negative acceleration of 4 mvs
positive acceleration of 4 ms
positive acceleration of 9 m/a
negatlveo acceleration of 9 m/s
Answers
Answer:
negative acceleration of 4m/s²
Explanation:
Given parameters:
Initial velocity = 66m/s
Final velocity = 26m/s
Time taken = 10s
Unknown:
Description of the acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time.
It is mathematically expressed as;
acceleration = [tex]\frac{v - u}{t}[/tex]
v is the final velocity
u is the initial velocity
t is the time taken
Now insert the parameters and solve;
Acceleration = [tex]\frac{26 - 66}{10}[/tex] = -4m/s²
So, we see a negative acceleration of 4m/s²

A student wearing a frictionless roller skates on a horizontal is pushed by a friend with a constant force of 55N. How far must the student be pushed, starting from rest, so that her final kinetic energy is 362 J
Answers
Answer:
6.58m
Explanation:
The kinetic energy = Workdone on the roller
Workdone = Force * distance
Given
KE = Workdone = 362J
Force = 55N
Required
Distance
Substitute into the formula;
Workdone = Force * distance
362 = 55d
d = 362/55
d = 6.58m
Hence the student must push at a distance of 6.58m
Which type of friction opposes motion?
Answers
Answer:
Friction does not oppose motion, it oppose relative motion.
Explanation:
static friction opposes relative motion
Answer:
there are three types or friction
1) Static friction
2) Rolling Friction
3) Sliding friction
Static friction comes to end when the object starts moving(or starts motion ) so Sliding Friction and Rolling Friction opposes motion l.
9. An object moving at a constant velocity accelerates at a constant rate of 20 m/s for a distance of
100 m. At the end of the acceleration the object has a velocity of 80 m/s. What was its velocity
before accelerating?
Answers
Answer:
I believe the answer is roughly 49m/s
Explanation:
List all given variables:
Accel=20m/s^2
Dist=100m
Final velocity=80m/s
Initial velocity=?
Using the equation i=sqrt(f^2-2a*d) where i =initial velocity, f=final velocity, a=acceleration, and d=distance, we can plug in the known values and solve for initial velocity
i=sqrt(80^2-2*20*100)
i=sqrt(6400-4000)
i=sqrt(2400)
i=48.99, rounded up to 49m/s as the initial velocity
This is my speculation about this answer would appreciate if anyone can confirm this.

Ceiling fan
Explanation:
A ceiling fan is an example of electrical energy being converted to mechanical energy.
The blades of the fan are driven by motor within the system.
Energy in a system is converted from one form to the other. Energy is neither created nor destroyed as we know from the law of conservation of energy. In this regard, the electrical energy from the outlet powers the motor. As the motor inside the fan spins, the blade in turn begins to rotate. The motion of the blade is the expression of mechanical energy.an arrow is shot horizontally at a target 5 meters away with a velocity of 5 m/s. the target and bow are both 3 meters above the ground. will the arrow fall short, hit the target head on, or go above and past the target and by how much

In which case will an object float on a fluid? A) Buoyant force is greater than weight. B) Buoyant force is less than weight. C) Buoyant force equals weight. D) Buoyant force equals zero.
Answers
Answer:
The correct option is A
Explanation:
Buoyancy can be described as the upward force that causes an object to float on water. When the buoyant force of a liquid is greater than the weight of an object, the object will move to the surface of the liquid and float (because the buoyant force would be able to push it upwards). If the buoyant force is lesser than the weight of the object, the object will sink (because the buoyant force would not be able to push the object upwards). And when the buoyant force and weight of an object cancel out, the object would be suspended at the depth that this occurs.
Thus, from the explanation above, it can be deduced that for an object to float, buoyant force must be greater than weight of the object. Thus, the correct option is A.
An object will float on a fluid when the buoyant force acting on the object is equal to the weight of the object. This condition is described by option C: Buoyant force equals weight.
When an object is placed in a fluid, it experiences an upward force called the buoyant force. The buoyant force is a result of the pressure difference between the top and bottom surfaces of the object. It depends on the density of the fluid and the volume of the object submerged in the fluid.
For an object to float, the buoyant force must be equal to the weight of the object. If the buoyant force is greater than the weight, the object will experience a net upward force and will rise to the surface. In this case, the object will not remain floating, but rather float upwards.
If the buoyant force is less than the weight, the object will experience a net downward force and will sink in the fluid. The object will not float but instead submerge into the fluid.
