if an object on a horizontal frictionless surface is attached to a spring, displaced, and then released, it will oscillate. if it is displaced a distance 0.120 m from its equilibrium position and released with zero initial speed, then after a time 0.785 s its displacement is found to be a distance 0.120 m on the opposite side, and it has passed the equilibrium position once during this interval. Part A Find the amplitude.
Part B Find the period.
Part C Find the frequency.
Answers
The frequency of the spring is 0.57 Hz, B. The time period 1.75 s C. The amplitude 0.120 m.
Given,
Distance = 0.120 m
Time = 0.785 s
a)To solve the amplitude in this problem, initial displacement A=0.120m was displaced and released with zero initial speed.
The amplitude is the maximum displacement from equilibrium and it was maximum at the moment t=0.(∴The object goes from x=+A to x=-A and back to complete one cycle)
So the amplitude will be equal to the initial displacement A=0.120m
Therefore, the amplitude of the spring is 0.120m
b) movement from +A( max positive displacement) to -A (max negative displacement) took place during half the period of SHM
therefore interval by the spring will be,
0.785 s= T/2 ---> by further solving for T
T= 0.785 x 2
T=1.57 s
The period of the spring is 1.75 s
c) As we know that frequency is inversely proportional to the time period.
To find frequency of the spring:
f=1/T (∴T=1.75)
f=1/1.75
f=0.57Hz
Therefore, the frequency of the spring is 0.57 Hz with the time period of 1.75 s and amplitude 0.120 m.

For the same angle of incidence, the angle of 'refraction in
three different media A, B and C are 10°, 25° and 40°,
respectively. In which medium the velocity of light will be
maximum?
Answers
Answer:
In the medium where the angle of incedence is 10°
Explanation:
This is because angle of incedence is directly proportional to refractive index of a medium.
Since refractive index is inversely proprtional to speed of light in medium, it will be the case.
The 800 kg roller coaster starts from rest at point W, which is 20 meters high. If 50,000 J of energy are "lost" to heat, how fast will the roller coaster be traveling at point X?
Answers
Answer:
11.18 m/s.
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 800 kg
Height (h) = 20 m
Energy (E) = 50000 J
Velocity (v) =?
The velocity of the roller coaster can be obtained as follow:
E = ½mv²
50000 = ½ × 800 × v²
50000 = 400 × v²
Divide both side by 400
v² = 50000 / 400
v² = 125
v = √125
v = 11.18 m/s
Therefore, the velocity of the roller coaster is 11.18 m/s.
what average force, in newtons, was exerted to slow him if he was moving horizontally? (the gravitational force is balanced by the buoyant force of the water.)
Answers
The average force that was exerted to slow the object is 0 N.
To find the average force that was exerted to slow the object, we can use the formula:
F = mΔv / Δt
Where:
F = force (in Newtons)
m = mass (in kilograms)
Δv = change in velocity (in meters per second)
Δt = change in time (in seconds)
Given that the gravitational force is balanced by the buoyant force of the water, the net force on the object is zero. This means that the average force exerted to slow the object is also zero.
Therefore:
F = 0 N

The effect of tornadoes on the environment is a path through a town with uprooted trees. This, option B is correct.
What are tornadoes?It is the typical weather event that contains strong winds and leaves a path of destruction up to 50 miles long. It is also defined as the violently rotating column of air that touches the ground and is usually attached to a thunderstorm.
It is developed from a severe thunderstorm in warm, moist, and unstable air and extended up to 300 miles. The thunderstorms also generate heavy damage and devastate the environment in seconds and cause more fatalities.
A swirling, funnel-shaped, whirling wind is called a tornado and it is accompanied by hurricanes and storms. Strong tornadoes last for twenty minutes and the winds are between 200 mph to 300mph. The United States and Canada are mostly tornado-affecting countries.
The effect of tornadoes is a path through a town with uprooted trees and hence, the ideal solution is option B.

Jose applies a force of 20 N North, Johnny applies a force of 10 N West and Janie applies a force of 25 N south on a heavy dresser. Find the resultant force on the dresser.
Answers
Answer:
Resultant force of the given forces: approximately \(11.2\; {\rm N}\) at approximately \(53^{\circ}\) west of south.
Explanation:
The resultant force of these forces will be:
\(25\; {\rm N} - 20\; {\rm N} = 5\; {\rm N}\) to the south (the \(20\; {\rm N}\) force to the north partially balances the \(25\; {\rm N}\) force to the south), and\(10\; {\rm N}\) to the west.Refer to the diagram attached. The resultant \(5\; {\rm N}\) force to the south and the \(10\; {\rm N}\) force to the west are perpendicular to each other, forming the two legs of a right triangle. The hypotenuse of this right triangle will be the net effect of these two forces.
Apply Pythagorean's Theorem on this triangle to find the magnitude of this net effect:
\(\begin{aligned}(\text{length of hypotenuse}) &= \sqrt{10^{2} + 5^{2}} \approx 11.2\end{aligned}\).
Hence, the magnitude of this net effect will be approximately \(11.2\; {\rm N}\).
Let \(\theta\) denote the angle between this resultant force and west. In this right triangle:
\(\begin{aligned} \tan(\theta) &= \frac{(\text{opposite})}{(\text{adjacent})} \\ &= \frac{5\; {\rm N}}{10\; {\rm N}} \\ &= \frac{1}{2}\end{aligned}\).
\(\begin{aligned} \theta &= \arctan\left(\frac{1}{2}\right) \approx 27^{\circ}\end{aligned}\).
Hence, the angle between this resultant force and south will be approximately \((90^{\circ} - 27^{\circ}) = 63^{\circ}\). This resultant force will be at approximately \(63^{\circ}\) west of south.

How much gravitational energy does a 65 kg skydiver have 650 m up in the sky?
Answers
Answer:
G.P.E = 414050 Joules or 414.05 Kilojoules
Explanation:
Given the following data;
Mass = 65 kg
Height = 650 m
We know that acceleration due to gravity is equal to 9.8m/s²
To find the gravitational potential energy;
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;
\( G.P.E = mgh\)
Where;
G.P.E represents potential energy measured in Joules.m represents the mass of an object. g represents acceleration due to gravity measured in meters per seconds square. h represents the height measured in meters.Substituting into the equation, we have;
\( G.P.E = 65 * 9.8 * 650 \)
\( G.P.E = 414050 \)
G.P.E = 414050 Joules or 414.05 Kilojoules.

When a wave is transmitted from one substance to another, its refraction will change. Unless it reaches the second substance at a right angle, its direction will also change.
What is Refraction?Refraction is the redirection of a wave as it passes from one medium to another medium. The redirection of wave can be caused by the wave's change in speed or by a change in the medium of wave.
The refraction of light or change in the direction of path of light in other medium occurs because the light wave travels with different speeds in different media. When a ray of light passes from one medium to another medium, the direction of the wave changes except for zero degrees because of the change in its speed.

Answers
a. Maximum intensity is transmitted through all polarizers at angles of 0 and 180 degrees, while minimum intensity occurs at 90 degrees. At 0 and 180 degrees, the components of the light waves pass through the polarizers without being blocked. At 90 degrees, both the magnetic and electric components are blocked by the F polarizer, leading to minimum intensity.
b. There are twice as many cycles with three polarizers compared to two because the third polarizer adds another level of filtering, causing more variation in the intensity of the transmitted light as the angle of the second polarizer changes.
c. The maximum amplitude for three polarizers is lower than the maximum amplitude for two polarizers because the additional polarizer blocks more of the light's components, reducing the overall intensity. This agrees with the theory that adding more polarizers will decrease the maximum transmitted intensity.

A motor cyclist travelling at 10 ms-1 decelerates at 2 ms-2.(a) How long does he take to come to rest?(b)How far does he travel in coming to rest?
Answers
Answer:
Explanation:
Formula
a = (vf - vi)/t
Givens
a = -2 m/s^2 Note, he is decelerating so the number must indicate he's slowing down. That's why it is minus.
vi = 10 m/s
vf = 0
Solution
-2 m/s^2 = (0 - 10)/t
-2 m/s^2 = -10 / t Multiply both sides by t
-2 m/s^2 * t = - 10 m/s / Divide by - 2
t = -10 / - 2
t = 5 seconds.
