A common urban legend propped up in the 1930’s with the opening of the Empire State Building. The legend says that if you throw a penny off the top of the building, it will fall all the way to the ground gaining speed all the way.
1) Calculate the time of flight of the penny (neglect air resistance). Show all work.
2) Calculate the final speed of the penny. Show all work.
3) Convert the final speed of the penny to miles per hour.
When a body is thrown downwards, it falls freely under gravity.
Acceleration under gravityThe question is incomplete as the values are missing but I will try to help you the much I can. We must note that the acceleration of a body refers to the rate at which its velocity changes per unit time.
When an object is thrown down from a height. It gains speed due to acceleration due to gravity which acts on the body as it falls freely.

The force needed to move a body in a curved way is understood as centripetal force. The centripetal force on Miguel will be 224 N.
What is centripetal force?The force needed to move a body in a curved way is understood as centripetal force. This is a force that can be sensed from both the fixed frame and the spinning body's frame of concern.
The direction of centripetal force is always in the path of the center of the course.
The given data in the problem is
v is the tangential speed = 3.50 m/sec.
r is the radius of circle= 0. 600 m
m is mass of Miguel = 11. 0 kg

The Galileo spacecraft measured that the moon Ganymede had a magnetic field, indicating that its interior was at least partly melted and warm. What do scientists think is the most likely reason for this
Scientists think the most likely reason is that it was heated by tidal forces from Jupiter.
What is Tidal force?This is known as the gravitational effect that stretches an object along the line towards the center of mass of another object as a result of gradient in gravitational field from the other body.

The bulb is at full brightness when the potential difference across the bulb is 12v
The current through the bulb is then 3A
Calculate the power of the bulb when it is at the full brightness and give the unit?
SOMEONE PLEASE HELP MEE <33
Answer:
36W
Explanation:
Using P=VI
Where:
P = Power of the light bulb (in Watts W)
V = Voltage of the light bulb (in Volts V)
I = Current passing through the light bulb (in Ampere A)
P = 12V * 3A = 36W

Consider the following debate between two students about the cause of the phases of the Moon and answer the question: Student 1: The phase of the Moon depends on how the Moon, Sun, and Earth are aligned with one another. During some alignments only a small portion of the entire Moon's surface will receive light from the Sun, in which case we would see a crescent moon. Student 2: I disagree. The Moon would always get the same amount of sunlight; it's just that in some alignments Earth casts a larger shadow on the Moon. That's why the Moon isn't always a full moon.
Do you agree or disagree with either or both of the students?
The moon rotates round Earth, we see it as crescent moon.Hence, I agree with the initial student.
Sun, Moon, Earth and RotationsGenerally, due to the fact he rightly stated that the positions of the Earth, Sun and moon continues on altering consistently due to the motion of moon round Earth.
Now, when the moon comes in between the Sun and the Earth about 1/2 component of the moon receives sunlight.
Similarly, as the moon rotates round Earth, a Earth will see the Sun-rays on the Moon coming from distinct angles and when solely a small element of the moon is illuminated via sunlight, we see it as crescent moon.
Therefore,I agree with the initial student

A trumpet player on a moving railroad flatcar moves toward a second trumpet player standing alongside the track both play a 660 Hz note. The sound waves heard by a stationary observer between the two players have a beat frequency of 2.0 beats/s. What is the flatcar's speed?
Answer:
Since the beat frequency is 2/sec and one of the players is moving towards the stationary observer (he will hear 660 / sec from the trumpet player that is also stationary), the player moving towards the observer will produce a frequency of 662/sec as heard by the observer.
f' = f * v / (v - vs) where vs is the speed of the source
We can use 331 m/s as the speed of sound in dry air
f' v - f' vs = f v rearranging
vs = v (f' - f) / f'
vs = 331 m/s * (662 - 660) / 662 = 1 m/s
What is the value of a charge that has an electric potential of 325 V and an electric potential energy of 0. 025 J?.
The value of the charge will be 7.69 ×10⁻⁵ C. When the matter is subjected to an electromagnetic field, it acquires an electric charge, which causes it to experience a force.
What is electric potential?Electric potential is the amount of work needed to move a unit charge from a point to a specific point against an electric field.
The given data in the problem is;
[tex]\rm E_p[/tex] is the electric potential energy = 0. 025 J
V is the electric potential = 325 V
Q is the charge =?
Electric potential energy is the product of the charge and the voltage. So the value of the charge is given as;
[tex]\rm E_p= Q \times V \\\\ \rm Q= \frac{ E_p}{V} \\\\ Q= \frac{ 0.025}{325} \\\\ \rm Q = 7.69 \times 10^{-5} \ C[/tex]
Hence the value of the charge will be 7.69 ×10⁻⁵ C.
