While standing on a balcony a child drops a penny. The penny lands on the ground floor 1.5 s later. How fast was the penny traveling vertically when it struck the ground floor? *The height of the balcony is 11.025 meters

​

Answers

Answer:

14.7 m/s.

Explanation:

From the question given above, the following data were obtained:

Time (t) = 1.5 s

Acceleration due to gravity (g) = 9.8 m/s².

Height = 11.025 m

Final velocity (v) = 0 m/s

Initial velocity (u) =?

We, can obtain the initial velocity of the penny as follow:

H = ½(v + u) t

11.025 = ½ (0 + u) × 1.5

11.025 = ½ × u × 1.5

11.025 = u × 0.75

Divide both side by 0.75

u = 11.025/0.75

u = 14.7 m/s

Therefore, the penny was travelling at 14.7 m/s before hitting the ground.

What is the acceleration of all objects due to gravity? What does this mean?

Answers

Every body that has larger mass has a field of attraction called gravitational field. All objects abandoned in the region of this great body is attracted to its center. The large body prints the object an acceleration which is called the acceleration of gravity.
Gravity acts on everything. The force if gravity is equal to 9.8 m/s^2

I am really struggling with this question because I can't find anything on aphelion and perihelion, it's not a topic we went over because it is an extra assignment. 4. How far away from the sun was Mercury at aphelion? On what day did aphelion occur?
5. How far away from the sun was Mercury at perihelion? On what day did it occur?
6. How many days elapsed between aphelion and perihelion? What percent of the time to complete one orbit was this?
7. What was the average radius of Mercury in its orbit that you calculated? How does it compare to the accepted value of 0.387 AU? Calculate the percent error using the following equation. Show your work.

If someone could explain it to me I would really appreciate it!

Answers


I have a strange hunch that there's some more material or previous work
that goes along with this question, which you haven't included here.

I can't easily find the dates of Mercury's extremes, but here's some of the
other data you're looking for:

Distance at Aphelion (point in it's orbit that's farthest from the sun):
69,816,900 km
0. 466 697 AU

Distance at Perihelion(point in it's orbit that's closest to the sun):
46,001,200 km
0.307 499 AU

Perihelion and aphelion are always directly opposite each other in
the orbit, so the time between them is  1/2  of the orbital period.

Mercury's Orbital period = 87.9691 Earth days

1/2 (50%) of that is  43.9845  Earth days

The average of the aphelion and perihelion distances is

     1/2 ( 69,816,900 + 46,001,200 ) = 57,909,050 km
or
     1/2 ( 0.466697 + 0.307499) = 0.387 098  AU
 
This also happens to be 1/2 of the major axis of the elliptical orbit.

In a transverse wave ,if you increase of the wave you will get what kind of wavelength

Answers

using the formula v = f λ, 
where v is the velocity of the wave, f is the frequency of the wave and λ is the wavelength of the wave. 

assuming that the velocity of the wave remains constant, by increasing the wavelength the frequency must decrease.
