Identify what happens to the kinetic energy (KE) and gravitational potential energy (PE) of a rock as it falls.
KE and PE both increase.
KE and PE both decrease.
KE increases and PE decreases.
KE decreases and PE increases.
Answer:
KE increases and PE decreases.
Explanation:
POTENTIAL ENERGY (PE):
The potential energy of the rock depends upon the height of the rock, as given by the following formula:
P.E = mgh
Therefore, the potential energy will be highest at the initial point due to the highest height attained by rock. As the rock falls, its height will decrease as a result its potential energy will also decrease.
KINETIC ENERGY (KE):
The kinetic energy of the rock depends upon the velocity of the rock, as given by the following formula:
[tex]K.E = \frac{1}{2}mv^2[/tex]
Therefore, the kinetic energy will be zero at the initial point due to the zero velocity of the rock. As the rock falls, its velocity will increase as a result its kinetic energy will also increase.
Hence, the correct option will be:
KE increases and PE decreases.
explain the forces of that affect the soccer balls path.
Answer:
yeah its correct
Explanation:
As the ball spins, friction between the ball and air causes the air to react to the direction of spin of the ball. ... Therefore, when a soccer player kicks the ball right of center the ball spins counter-clockwise and the Magnus force acts left, causing the ball to curve left.

A friend says to you, “I’m the fastest runner in my class because I can run four miles without stopping.” Explain to your friend why her statement doesn’t make sense.
Answer:
Just because they can run doesn't mean they are fast
Explanation:
you could take a day to run across a football field, or you can take 5 minutes, which is faster?
You're friend in this equation has little to no braincells so they would have trouble seeing that running the length of a football field in five minutes is faster than a day, however, if they also said they did it in less than five minutes then it would mean your friend is fast
What is the rate at which velocity changes called?
Why the temperature of a resistor increase when a current pass through it
Answer:
So, when an electrical charge passes through a resistor, some of that electrical energy is transferred into heat, increasing the temperature. This extra energy causes the particles in the resistor to vibrate more. With these particles moving more, it is more difficult to for the electrons to move through the resistor.
The Atomic number tells us the number of ____ in an atom.
Answer:
Protons
Explanation:
Answer: protons
Explanation:
what are newtons laws of motion?
Answer:
In classical mechanics, Newton's laws of motion are three laws that describe the relationship between the motion of an object and the forces acting on it. The first law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force.

can anybody help me please?
Answer:
1,2,5
Explanation:
The EMF does not depend on which of the following?
A. The magnetic field strength
B. The number of electrons in the magnetic field
C. The velocity of the wire in the field
D. The length of the wire in the magnetic field
Answer:
Explanation:
When a wire of length L is moved with velocity v , perpendicular to magnetic field B , EMF will be produced at its two ends . EMF can be calculated with the help of following expression
EMF = BLv
As per this formula , EMF produced will not depend upon number of electrons in the magnetic field.
So B is the right choice.
A current of 2 A flows through a resistor. The voltage across the resistor is 18 V.
pls I need this
Answer:
[tex]R=9\ \Omega[/tex]
Explanation:
Given that,
Current, I = 2 A
Voltage across the resistor, V = 18 V
We need to find the value of resistance of the resistor. Let the resistance be R. We can find it using Ohm's law i.e.
V = IR
Where
R is the resistance of the resistor
[tex]R=\dfrac{V}{I}\\\\R=\dfrac{18}{2}\\\\R=9\ \Omega[/tex]
So, the resistance of the resistor is equal to [tex]9\ \Omega[/tex].

Which change happens in an endothermic chemical process??
Answer:
The thermal energy is absorbed
Explanation:
In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction.

15. What is the impedance of a series combination of a resistance of 1KM and a capacitance of a capacitor 2 µF at a frequency of 50 Hz? Nt
Answer:
Z = 1879.64 Ω = 1.879 KΩ
Explanation:
First, we will find the capacitive reactance of the capacitor:
[tex]X_{c} = \frac{1}{2\pi fc}\\[/tex]
where,
Xc = Capacitive Reactance = ?
f = frequency = 50 Hz
C = Capacitance = 2 μF = 2 x 10⁻⁶ F
Therefore,
[tex]X_{c} = \frac{1}{2\pi(50\ Hz)(2\ x\ 10^{-6} F)}\\X_{c} = 1591.55\ \Omega[/tex]
This is an RC series circuit. In the RC circuit the value of impedance is given by the following formula:
[tex]Z = \sqrt{R^2 + X_{c}^2}\\Z = \sqrt{(1000\ \Omega)^2 + (1591.55\ \Omega)^2}\\[/tex]
Z = 1879.64 Ω = 1.879 KΩ
