A light wave travels through glass (n=1.50) at an angle of 35°. What angle
does it have when it passes from the glass into the air (n = 1.0)?
A. 59.4
B. 0.860
C. 22.5
D. 0.382
Answer:
A. 59.4
Explanation:
The refractive index of the glass, n₁ = 1.50
The angle of incidence of the light, θ₁ = 35°
The refractive index of air, n₂ = 1.0
Snell's law states that n₁·sin(θ₁) = n₂·sin(θ₂)
Where;
θ₂ = The angle of refraction of the light, which is the angle the light will have when it passes from the glass into the air
Therefore;
θ₂ = arcsin(n₁·sin(θ₁)/n₂)
Plugging in the values of n₁, n₂ and θ₁ gives;
θ₂ = arcsin(1.50 × sin(35°)/1.0) ≈ 59.357551° ≈ 59.4°
The angle the light will have when it passes from the glass into the air, θ₂ ≈ 59.4°.

A cyclist traveling at 30.0m/s along a straight road comes uniformly to stop in 5.00s. Determine the stopping acceleration, the stopping distance.
Answer:
I. Stopping acceleration = 6 m/s²
II. Stopping distance, S = 75 meters
Explanation:
Given the following data;
Final velocity = 30 m/s
Time = 5 seconds
To find the stopping acceleration;
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
Substituting into the equation;
[tex]a = \frac{30 - 0}{5}[/tex]
[tex]a = \frac{30}{5}[/tex]
Acceleration = 6 m/s²
II. To find the stopping distance, we would use the third equation of motion;
[tex] V^{2} = U^{2} + 2aS [/tex]
Where;
V represents the final velocity measured in meter per seconds.
U represents the initial velocity measured in meter per seconds.
a represents acceleration measured in meters per seconds square.
Substituting into the equation, we have;
30² = 0² + 2*6*S
900 = 12S
S = 900/12
S = 75 meters
Magali exerts a force of 4.5 N to slide her Blackberry across the table (so she can hide it from Hina!). If she does 2.7 J of work in the process, how far has the Blackberry moved?
Work is equal to the magnitude of the force multiplied by the displacement x. Assuming Magali is pushing the phone, so that the force and displacement point in the same direction, then the work done is positive, and
2.7 J = (4.5 N) x ==> x = (2.7 J) / (4.5 N) = 0.60 m
Even if she was pulling the phone instead, the displacement would be the same, but the work done would be negative and the force would point in the opposite direction, thus also having a negative sign:
-2.7 J = (-4.5 N) x ==> x = 0.60 m
Arches National Park is a desert landscape located in Utah. The park is filled with arches that have been formed by nature. The arches were once solid rock.

Which of these processes is responsible for the formation of the arches?
a.cooling magma
b.weathering and erosion
c.compaction and cementation
d.increased geological pressures
Two forces that make up 3rd law of motion can: 1)Act on the same object 2)do not act on same time 3)Act on different objects 4)Do not act oppositely
Answer:
3) Act on different objects
Explanation:
Newton's third law of motion states that for every action there is an equal and opposite reaction.
Action-reaction force pairs make it possible for fishes to swim, birds to fly, cars to move, etc.
Basically, action-reaction force pairs are characterized by the following statements;
I. The forces are the same type such as magnetic force, contact force or gravitational force.
II. The forces are equal in magnitude but opposite in direction.
III. They act up on two different bodies.
Hence, the two forces that make up 3rd law of motion can act on different objects.
For example, while driving down the road, a bug strikes the windshield of a vehicle (Action) and makes a quite obvious mess in front of the face of the driver of the vehicle (Reaction) i.e the bug hit the vehicle and the vehicle hits the bug.

47.206,432 - 6 = 47.200,432
What is the answer to this question?
Answer:
Explanation:
In a velocity/time (aka acceleration) graph, the slope of a line indicates the value of the acceleration in m/s/s. Acceleration is the change in velocity over the change in time. From 0 - 2 seconds, there is no change in velocity, so the acceleration during this interval is 0 (which is the same as the slope of the line). From 2 - 4 seconds, the slope of the line is -2, so the acceleration during the time interval from 2 to 4 seconds is -2 (negative because David is slowing down but is still going the same direction: to the right).

Mike roller skates with a constant speed of 10 miles per hour. How long will he take to travel a distance of 15 miles.
Answer:
So every hour he makes 10 miles. So he would take 1 and a half hours to go to Mcdonalds 15 miles away.
Explanation:
[tex]\huge\boxed{{\textsf{90 minutes}}}[/tex]
We know that Mike's speed is [tex]\dfrac{10\ \text{miles}}{60\ \text{minutes}}[/tex] since there are [tex]60[/tex] minutes in an hour, and we know that MIke needs to travel [tex]15[/tex] miles. We'll model this using fractions:
[tex]\dfrac{10\ \text{miles}}{60\ \text{minutes}}=\dfrac{15\ \text{miles}}{x\ \text{minutes}}[/tex]
We can see that there is a [tex]2:3[/tex] ratio here, so we'll divide the left fraction by [tex]2[/tex] and multiply it by [tex]3[/tex] to get the right fraction.
[tex]\dfrac{10}{60}\Rightarrow\dfrac{5}{30}\Rightarrow\dfrac{15\ \text{miles}}{\boxed{90\ \text{minutes}}}[/tex]

The speed of light in vinegar is 2.30 x 10^8 m/s. Determine the index of refraction. (2
Answer:
[tex]n _{v} = \frac{c}{v} \\ = \frac{3 \times {10}^{8} }{2.30 \times {10}^{8} } \\ = 1.30[/tex]
This question involves the concept of refractive index.
The refractive index of the vinegar is "1.3".
What is the Refractive Index?The refractive index is defined as the ratio of the speed of light in air and the speed of light in the given medium which is vinegar here.
[tex]\eta = \frac{c}{v}[/tex]
where,
[tex]\eta[/tex] = refractive index = ?c = speed of light in air = 3 x 10⁸ m/sv = speed of light in vinegar = 2.3 x 10⁸ m/sTherefore,
[tex]\eta = \frac{3\ x\ 10^8\ m/s}{2.3\ x \10^8\ m/s}[/tex]
η = 1.3

what will happen to satellite if the linear speed is reduced?. give a reason for your answer
Explanation:
If the satellite is moving too quickly then the gravitational attraction between the Earth and the satellite is too weak to keep it in orbit. If this is the case, the satellite will move off into space. This occurs at speeds around or above 11,200 metres per second (m/s).
If a wire with current 5.0A has 12 coulombs of charge pass through it how much has passed
Answer:
2.4 secs.
Explanation:
Current (A) = Charge (coulomb)/Time(sec)
We are looking for time. So:
Time (sec) = Charge (coulomb)/Current (A)
↓
12coulombs/5.0A = 2.4 secs

Spaceship 1 and Spaceship 2 have equal masses of 150 kg. Spaceship 1 has an initial momentum magnitude of 900 kg-m/s. What is its initial speed?
A. 9 m/s
B. 6 m/s
C. 90 m/s
D. 60 m/s
Answer:
ans: 6 m/s
Explanation:
spaceship 1 has mass= 150kg
initial momentum of spaceship 1 = 900 kg•m/s
we know,
momentum = mass × velocity
so,
velocity = momentum/mass
= 900 / 150
= 6 m/s
since we know it was initial momentum so, velocity is initial speed,
Which car safety features absorb kinetic energy?
A. Seat belts and air bags
B. Seat belts and crumple zones
C. Seat belts, crumple zones and air bags
Answer:
C
Explanation:
Seat belts absorb kinetic energy when a car crashes because it pulls you back from falling forward given the kinetic energy (and momentum) you had before the crash.
Air bags absorb kinetic energy when a car crashes because it pushes you back from falling forward given the kinetic energy (and momentum) you had before the crash.
Crumple zones absorb kinetic energy when a car crashes because it provides a cushion when the cars crash. Kind of like dropping your phone into a pillow.

A sled drops 20 mts in height on a hill. The rider is going 20 m/s at the bottom of the hill. Where can you find kinetic and potential energy? In which moments?
Explanation:
Potential energy is the energy occupied by an object or substance due to its position.
For example, a sled drops 20 meters in height on a hill shows that a decrease in height is taking place.
Hence, potential energy is involved there.
Kinetic energy is the energy acquired by an object due to its motion.
For example, a rider is going 20 m/s at the bottom of the hill shows that rider is in motion due to which it has kinetic energy.

You lift a 44 N box from the floor and place it on a shelf that is 1.5 m above the ground . How much work did you use in lifting the box ?
Answer:
W = 66 J
Explanation:
Given that,
The weight of the box, W = 44 N
It is placed on a shelf that is 1.5 m above the ground.
We need to find the work done in lifting the box.
We know that,
Work done, W = Fd
So,
W = 44 N × 1.5 m
= 66 J
So, the required work done is equal to 66 J.
