Photograph E shows a rechargeable torch. When a student shakes the torch, the magnet moves through the coil and back again. This induces a voltage across the ends of the coil. The voltage is used to provide current to recharge the battery. (a) Explain why a voltage is induced (b) State one way to increase this voltage
Answer:
a) according to Faraday's law , b) creating a faster movement, placing more turns on coil
Explanation:
a) The voltage is induced in the coil by the relative movement between it and the magnet, therefore according to Faraday's law
E = - d (B A) / dt
In this case, the magnet is involved, so the value of the magnetic field varies with time, since the number of lines that pass through the loop changes with movement.
This voltage creates a current that charges the battery
b) There are several ways to increase the voltage
* creating a faster movement, can be done by the user
* placing more turns on the coil, must be done by the manufacturer

All objects, regardless of their mass, fall with the same rate of acceleration on
the moon.
A. True
B. False
Answer:
A -TRUE
Explanation:
The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration.

As shown in the figure below, April enters a race. She runs leftward 100 m to her horse, then she rides 500m to her truck, then she drives 1000m in a total time of 120s. What is her average velocity over the 120s period?
Answer:
The answer is below
Explanation:
The average velocity is the ratio of total distance traveled to the total time taken to complete the distance. The International System of Units (SI) unit of velocity is the meter per second (m/s). The Velocity is given by the equation:
Velocity = total distance traveled / total time taken
The total distance traveled = Distance traveled by horse + distance traveled by truck + remaining distance traveled = 100 m + 500 m + 1000 m = 1600 m
Total time taken = 120 s
Velocity = total distance traveled / total time taken = 1600 m / 120 s = 13.33 m/s
Velocity = 13.33 m/s

As the skydiver falls to Earth, her parachute helps her land safely by:
C. warming the
a. increasing air resistance
surrounding air
b. acting like a helium-filled balloon
d. blocking the Sun's rays
Answer: A
Explanation: How large a parachute is (in other words, the parachute's surface area) affects its air resistance, or drag force. ... In the case of these parachutes, the drag force is opposite to the force of gravity, so the drag force slows the parachutes down as they fall.
Answer:
a
Explanation:
a is the answer to that question, increasing air resistance surrounding air

HOPE YOU RATE THE ANSWER..A TV set shoots out a beam of electrons. The beam current is 10A. How many electrons strike the TV screen in a minute.
Answer:
600 mC
Explanation:
The charge of an electron is 1.6 x 10-19C so for a current with 10 mA, the charge going to screen in one second is 10 mC
so number of electrons, n = (10 x 10-3)/(1.6 x 10-19) = 6.25 x 1016 so in a minute the charge is 10 * 60 = 600 mC
Answer:
Total charge, q = It = 10 A x 60 s = 600 C
We know that, q = ne
So no. of electrons, n = q/e = 600 / (1.6×10-19) = 375x1019
Suppose a tank filled with water has a liquid column with a height of 10 meters. If the area is 2 square meters (2 m²), what's the force of gravity acting on the column of water?
Answer:
196000 N
Explanation:
The following data were obtained from the question:
Height (h) = 10 m
Area (A) = 2 m²
Force (F) =.?
Next, we shall determine the pressure in the tank.
This can be obtained as follow:
P = dgh
Where
P is the pressure.
d is the density of the liquid.
g is acceleration due to gravity
h is the height.
Height (h) = 10 m
Density (d) of water = 1000 kg/m³
Acceleration due to gravity (g) = 9.8 m/s²
Pressure (P) =...?
P = dgh
P = 1000 × 9.8 × 10
P = 98000 N/m²
Therefore, the pressure acting on the tank is 98000 N/m²
Finally, we shall determine the force of gravity acting on the column of water as follow:
Area (A) = 2 m²
Pressure (P) = 98000 N/m²
Force (F) =.?
Pressure (P) = Force (F) /Area (A)
P = F /A
98000 = F/ 2
Cross multiply
F = 98000 × 2
F = 196000 N
Therefore, the force of gravity acting on the column of water is 196000 N

If it were not for this, your car would be unable to move.
torque and traction
O centrifugal force and kinetic energy
centrifugal force and gravity
torque and centrifugal force
Answer:
centrifugal force and kinetic energy
Explanation:
Without centrifugal force and kinetic energy, a car would be unable to move.
A centrifugal force regulates the speed of the engine using spinning masses and causes radial movement when the engine changes speed.
The kinetic energy is the energy which an object possesses due to its motion and car also require kinetic energy to move.
Hence, the correct answer is centrifugal force and kinetic energy.

Answer:
C deceive participants
Explanation:
It is ethical practice to come clean or tell the truth about being deceptive at the end of the study. They need to be told that they were deceived.
In order to stop experimental subjects from trying to confirm the scientist's hypothesis, psychologists sometimes deceive participants about the true purpose of the experiment. The correct option is C.
What is psychologists?Psychologists can help people learn to cope with stressful situations, overcome addictions, manage chronic illnesses, and administer tests and assessments that can aid in the diagnosis of a condition or reveal more about a person's thoughts, feelings, and behaviors.
Psychotherapy can be aided by both psychologists and psychiatrists.
However, most psychiatrists treat patients primarily through medication, whereas psychologists primarily treat patients through talk and/or behavioral therapy.
People seek the help of a clinical psychologist to deal with mood-related issues such as depression, mania, anger, or anxiety.
Psychologists sometimes deceive participants about the true purpose of the experiment in order to prevent experimental subjects from attempting to confirm the scientist's hypothesis.
Thus, the correct option is C.
