Where on the track would the cart have the most kinetic energy?
Group of answer choices
Position A
Position B
Position C
Position D
Answer:
Position C
Explanation:
Position A has the highest amount of potential energy. At position C, most of that potential energy was transformed to kinetic energy. Because it is at the bottom part of the hill, and is beginning to reclimb, point C has the highest kinetic energy.
The energy of the body by the virtue of its motion is known as the kinetic energy of the body. At position C on the track would the cart have the most kinetic energy.
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 can not be created nor be destroyed can be transferred from one form to another form.
The total energy is defined as the sum of kinetic energy and potential energy.
Total energy = kinetic energy+potential energy
Position A contains the most potential energy. The majority of that potential energy was converted to kinetic energy at location C.
Point C has the most kinetic energy since it is at the bottom of the slope and is starting to climb again.
Hence at position C on the track would the cart have the most kinetic energy.

A person is standing on a raft; their
combined mass is 233 kg. What is the
volume of water displaced by the raft?
[?] m3
Pwater = 1,000 kg/m3
Answer:
The volume of water displaced by the raft is 0.233 m³
Explanation:
The question relates to Archimedes' principle which states that the buoyant force experienced by an object immersed in a fluid is equal to the weight of (the force of gravity on) the displaced fluid
The given parameters are;
The combined mass of the person and the raft, m = 233 kg
The liquid on which the raft is located = Water
The density of water, [tex]\rho _{water}[/tex] = 1000 kg/m³
Weight = Mass, m × g
Where;
m = The mass of the object
g = The acceleration due to gravity = 9.8 m/s²
Given that the raft is on the surface of the water (floating), the buoyant force is equal to the combined weight of the person and the raft = 233 kg
The combined weight of the person and the raft, [tex]W_{combined}[/tex] = 233 kg × 9.8 m/s² = 2,283.4 N
Therefore;
The buoyant force = 2,283.4 N = The weight of the water displaced
The mass of the water displaced, [tex]m_{water}[/tex], = 2,283.4 N/(9.8 m/s²) = 233 kg
Density = Mass/Volume
The volume of water displaced by the raft = The mass of the water displaced/(The density of the water) = 233 kg/(1,000 kg/m³) = 0.233 m³.
Answer:
the volume displaced by the raft = 0.233 m3

Which of the following actions will always decrease voltage?
A. Decreasing resistance and increasing current
B. Increasing resistance and decreasing current
C. Decreasing resistance and keeping current constant
D. Increasing resistance and keeping current constant
Answer:
D. Increasing resistance and keeping current from A P E X :))
Explanation:
The decreasing resistance and keeping current constant leads decreasing in voltage option (C) is correct.
What is voltage?Voltage is the force applied by the power source to charged electrons in a conducting loop, allowing them to perform tasks such as igniting light.
As we know according to the ohm's law:
V = IR
Where 'V' is the volatge,
'I' is the current.
'R' is the resistance.
If we assume 'I' is constant
Then V∝R
As the resistance increases the voltage increases and vice versa.
Thus, the decreasing resistance and keeping current constant leads decreasing in voltage option (C) is correct.

Michael's car ran over a nail which made a hole in one of the tires letting the pressurized air in the tire out of it at what point will it stop pouring out of the hole in the tire
Answer:
The air will stop pouring out of the hole in the tire when the pressure inside the tire is equal to atmospheric pressure
Explanation:
The question relates to equilibrium conditions
The given parameters are;
The condition of the pressure of the air in the tire, P = Pressurized, P > Atmospheric pressure
The pressurized air is let out of the tire through a hole made by a nail
Therefore;
When the pressure inside the tire is more than atmospheric pressure, the force per unit area of the air from the side of the hole inside the tire is more than the force per unit area acting in the opposite direction and the pressure forces the air out of the tire
Therefore, the air continues pouring out of the hole in the tire up to the point when the pressure inside the tire becomes equal to atmospheric pressure, at which point the force per unit area of the air on either side of the hole are equal.

A crate of toys remains at rest on a sleigh as the sleigh is pulled up a hill with an increasing speed. The crate is not fastened down to the sleigh. What force is responsible for the crates increase in speed up the hill
Answer: the force of static friction of the sleigh on the crate
Explanation:
The force that is responsible for the crates increase in speed up the hill is the force of static friction of the sleigh on the crate.
When a light horizontal push is applied and which isn't enough to move the box, the static friction force will also be directly opposite to the push.
When an individual pushes harder, the force of the friction will then be enough to create a push.
Your friend says that if Newton’s third law is correct, no object would ever start moving. Here is his argument: You pull a sled exerting a 50 N force on it. According to Newton’s third law the sled exerts the force of 50 N on you in the opposite direction. The total force is zero, thus the sled should never start moving. But it does. Thus Newton’s third law is wrong. What is your opinion about this answer? How can you convince your friend of your opinion?
pls help
Answer:
Explanation:
You pull a sled exerting a 50 N force on it , sled also exerts a force on you . These forces are action and reaction force , as per third law of Newton . These two forces are equal and opposite . But they do not act on the same object so they do not cancel each other . They act on different objects , one on the sledge and the other on you . Due to force on sledge , sledge moves in the direction of force or towards you . You will start moving in opposite direction if frictional force of ground is nil or less .

A circuit contains two 1.5 volt battery and a bulb with a resistance of 3 ohms. Calculate the current
Answer:
The current is 1 A
Explanation:
Current in a Series Connection
When two or more elements are connected in series, all of them have the same current, and the sum of their individual voltages is the total voltage applied to the circuit.
According to Ohm's law:
V=R.I
Where V is the voltage, R is the resistance and I is the current of a circuit.
We have a voltage of V=1.5 V + 1.5 V = 3 V and a resistance of R=3 ohms.
We can calculate the current by solving for I:
[tex]\displaystyle I=\frac{V}{R}=\frac{3}{3}=1\ A[/tex]
The current is 1 A
