Answer:
there is an infinite number of images because it is reflected off of the mirrors. the images in the mirror will "move" if either mirror is shifted because the angle of reflection. the images are the same because its just a repeated reflection. i see the object on both sides, repeated as far as i can see in both mirrors.
Explanation:
C = Sqrt (17.4^2 - 12.2^2) = 12.4
ArcTan (12.4/12.2) = 45.47 degrees above vector a, which is 134.53 degrees measured on the xy-axis.
It would take 5.0 s for a racehorse to accelerate from rest to a speed of 15 m/s with an acceleration of 3.0 m/s.
Take 15 / 3.0 to get your answer of D. 5.0 s
Hope that helps u out!
The answer is C. Gravitational potential energy is a function of the weight and the height of an object.
Answer:
Explanation:
We will need to use the ideal gas equation. The equation is given by:
- P is the pressure
- V is the volume
- n is the amount of molecules
- R is the ideal gas constant
As we have the same amount of molecules in the initial and final steps, therefore we can do this:
(1)
- P(1) is the atmospheric pressure (P(1) = 1 atm) and P(2) is 0.028 atm
- T(1) is 300 K and T(2) is 190 K
- V(1) is the volume of the balloon in the first step, we can consider a spherical geometry so:
(2)
(3)
- D(2) = 32 m
So
Let's solve the equation (1) for V(1)
And using the equation (2) we can find D.
I hope it helps you!
