Select the correct answer. Which feature of a wave determines its color in the visible spectrum? A. Amplitude B. Composition C. Temperature D. Wavelength.
Answers
Answer:
D. Wavelength
Explanation:
Explanation: the colour of visible light depends on the wavelength of the wave. The visible light spectrum goes approximately from wavelength of 380 nm (corresponding to violet light) to 750 nm (corresponding to red light), and the different colours in between correspond to different wavelengths.
A pendulum is released from a high position Because of friction, the pendulum eventually stops swinging Which of the following actions occur as the pendulum stops swinging?
a) Kinetic energy increases
b) Potential energy decreases
c) Kinetic energy remains the same
d) Potential energy remains the same
Answers
Answer:
b) Potential energy decreases
Explanation:
The reason why Potential energy decreases here is because you know that if you bounce a ball without applying any force to it, then it falls, and then comes back up, but does it come all the way up to where it was fallen from? NO! So that's why, each time the ball bounces, the potential energy goes down.
Thanks!

A car is moving with a lot of momentum. If it were moving at the same speed but had five times as much mass, its momentum would be
Answers
Answer:
5 times as much
Explanation:
the equation for momentum is p=mv
p(momentum)=m(mass)xv(velocity)
So if the velocity is the same, but the mass is multiplied by 5 the total momentum would be 5 times greater than the previous scenario.

A sphere of 0.047 kg aluminum is placed for sufficient time in a vessel containing boiling water, so that the sphere is at 100°C. It is then immediately transferred to a0.14 kg copper calorimeter containing 0.25 kg water at 20°C. The temperature of water rises and attains a steady state at 23°C. Find specific heat capacity of aluminum.
Answers
We know that,
Heat lost by the sphere = Heat gained by H₂O & Calorimeter
=> m₁ x c₁ x ∆T₁ = m₂ x c₂ x ∆T₂ + c₃ x m₃ x ∆T₂
=> 0.047 kg x c₁ x 77°C = 0.25 kg x 4.18 x 3°C+0.14 x 0.386 x 3°C
=> c₁ = ( 0.25 kg x 4.18 kg^-1 k^-1 x 3°C + 0.14kg x 0.386 kg^-1 k^-1 x 3°C ) / 0.047 kg x 77°C
=> c₁ = 3.30/ 0.047 x 77
=> c₁ = 0.913 KJ kg^-1 k^-1
Hence , the specific heat capacity of aluminum would be 0.913 KJ kg^-1 k^-1
A particle with charge q, mass m, and initial speed v0 in the x direction enters a region where the electric field is uniform in the x direction. How much time does it take for the particle to cross the region of length d
Answers
Answer:
S = 1/2 Vo t + 1/2 a t^2 = d time for particle to travel distance d
F = E q force acting on particle
a = F / m = E q / m
d = Vo t + E q / (2 m) t^2
One would need to solve the quadratic equation shown to find the time t
t^2 + (2 m) / E q * V0 t - (2 m) / E q * d = 0
or t^2 + A V0 t - A d = 0 where A = (2 m) / E q

The energy to the position is known as potential energy. The maximum potential energy is in case 2. Hence the maximum height will be in case 2.
What is kinetic energy?The energy of the body by the virtue of its motion is known as the kinetic energy of the body. It is defined as the product of half of mass and square of the velocity.
According to the law of conservation of energy, the total energy is defined as the sum of kinetic energy and potential energy.
Mechanical energy = kinetic energy+potential energy
Potential Energy = Mechanical Energy - Kinetic Energy
As a result, if an object has greater potential energy, it will have a higher height.
The formula for the kinetic energy is given by;
The potential energy for the different cases will be;
Case-1;
[tex]\rm KE_1=\frac{1}{2}mv^2 \\\\ \rm KE_1=\frac{1}{2}\times2.4(7)^2 \\\\ \rm KE_1=58.8 J[/tex]

Case-2;
[tex]\rm KE_2=\frac{1}{2}mv^2 \\\\ \rm KE_2=\frac{1}{2}\times2.4(2)^2 \\\\ \rm KE_2=4.8 J[/tex]

Case-4;

simulation
Respond in the space provided
Part B
Ruth used a spinner to perform 10 trials to simulate the probability of having three children with blue eyes She observed 1 outcome of having three children with blue eyes.
• Is Ruth's estimated probability representative of the theoretical probability of having three children with blue eyes? Explain why or why not.
• Provide the estimated probability from Ruth's simulation and the theoretical probability of having three children with blue eyes
Respond in the space provided
Answers
Answer: There is two event that needs to be made: 1. blue eyes, and 2. brown eyes. A spinner is made with a circle. A full circle has 360 degrees and it would be divided based on the probability of the event.
Blue eyes have 25% chance, so the angle of the spinner would be 25%*360°= 90°
Brown eyes have 75% chance, so the angle of the spinner would be 25%*360°= 270°
So, the 90° of the circle would be written as 1(blue eyes) and 270° of the circle will be written as 2(brown eyes).
