A student conducts an investigation to study the impact of solar energy on land and water surfaces. He places a cup of soil and a beaker filled with water of the same mass on a plastic tray beside a window. After 10 minutes, he measures that the temperature of the water in the beaker is lower than the temperature of the soil. He places the plastic tray in the shade of a tree, and after another 10 minutes, he measures that the temperature of the water in the beaker is higher than the temperature of the soil.

What can the student conclude from his investigation?

Lucia is playing with magnetic toy vehicles. She has two identical toy vehicles (purple and pink) that start on opposite sides of a center magnet that cannot move. She moves both vehicles one space closer to the center magnet Please explain what would happen if Lucia released hold on the two magnet cars. How do you know?

Answers

Answer:

They would connect

Explanation:

The cars are magnetic

Answer:

The potential energy of both toy vehicles, purple and pink, increased. The potential energy of the two vehicles increased because they were moved against the magnatic forces. The potential energy of the pink car increased more then the potential energy of the purple car because the pink car was closer to the center magnet. Since the pink toy was moved closer to the magnet, it will have more potential energy because of the short distance between it and the centre magnet. As we know, potential energy does not increase linearly. Meaning when because the pink magnet is closer to the centre magnet than the purple it will have a greater potential energy increase than the purple. The purple toy as well is now closer to the magnet and will have a potential energy change, but not as large as the pink's change.

(a) Waves P and Q have the same frequency, but wave P has twice the wavelength of wave Q

(b) Waves Q and R have the same wavelength, but wave R has twice the frequency of wave Q.

(c) Wave T shows a steady frequency but changing amplitude

(d) Wave S shows a steady amplitude but changing frequency

(e) Waves Q and R have a low amplitude and a steady frequency

HOPE THESE ARE RIGHT

a. wavelength,amplitude
b. Amplitude, wavelength
c. T
d. S
e. Q and R
hope they are fine for you to understand.
For more info,
Frequency are the number of waves passing a single point per second.
Amplitude is the distance from the equilibrium position to the maximum displacement.
Wavelength is the distance from one point of a wave to the same point of the next wave.

I have two questions
1. "Explain the relationship between amplitude and energy"

2."Explain the relationship between frequency and energy"

Answers

Answer:

1)The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy

2)Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.

Explanation:

The correct answer to the question is : C) A pendulum swings back and forth.
EXPLANATION:
Before answering this question, first we have to understand the law of conservation of energy.
As per law of conservation of energy, energy can neither be created not be destroyed. It can only change from one form to another form, and the total energy of the universe is always constant.
As per the question, we have a pendulum which is moving back and forth.
Let us consider a pendulum which is taken to some height from its equilibrium or mean point. The energy possessed by the pendulum at this height is gravitational potential energy. When the pendulum is released, the potential energy is converted into kinetic energy. At mean point, whole of its potential energy is converted into kinetic energy.
Due to inertia, the pendulum reaches at the other extreme point. During its movement from mean point to extreme point, the kinetic energy is converted into potential energy. At extreme point, whole of its kinetic energy must have converted into potential energy. The same process will be repeated.
Hence, it obeys law of conservation of energy.
Hence, swinging of pendulum back and forth is the best example to demonstrate the law of conservation of energy.
