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.

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.

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

Juan y Pedro transportan una caja que pesa 120,00 Lb sobre una tabla uniforme de 12 pies de largo y peso de 44,5 Lb. El peso de 120 Lb está a 4,9 pies de Pedro. ¿Cuál es el módulo de la fuerza en Lb que debe ejercer Pedro por el extremo derecho de la tabla horizontal para sostener este peso?
Answer:
F = 93.25 lb
Explanation:
To solve this problem let's use the rotational equilibrium condition
Σ τ = 0
let's fix a reference system located at the end of the table, the position of Juan and assume the counterclockwise turns as positive
F_jhon 0 - w l / 2 - W (l-4.9) + F l = 0
F = w l / 2 + W (l -4.9) / l
where w is the weight of the table and W the weight of the box
let's calculate
F = (44.5 12/2 + 120 (12- 4.9)) / 12
F = 93.25 lb

For maximum benefit, you should exercise 5-7 times a week for 60 minutes and your heart rate should be between _____________ of your max heart rate.
Answer:
60 to 80%
Explanation:
For maximum benefit, the heart rates during exercise regimes should be between 60 to 80% of an individual's maximum heart rate.
The maximum heart rate varies from individuals to individuals and largely depends on age. It is calculated by subtracting one's age from 220. For example, a person that is 40 years old would have a maximum heart rate of;
220 - 40 = 180 beats per minute.
Such a person's heart rates during exercises should be between 108 and 144 beats per minute for maximum benefits.

What quantities are needed to describe the position of a water fountain relative to where you are standing?
Answer:
D. the distance and direction to the water fountain
Explanation:
To describe the position of a water fountain relative to where one is standing, the distance and direction to the water fountain must be known.
This quantity is known as the displacement.
Displacement is a vector quantity with both magnitude and direction. To specify the magnitude of a displacement, we use the length of path and in this case the height or sometimes the distance. The direction attribute distinguishes distance from displacement The perfect quantity to solve this problem is the displacement and it specifies the distance of the path and the direction traveled.If a runner exerts 350 J of work to make 125 W of power, then how long did it take the runner to do the work?

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.
