Answer:
113 miles
Explanation:
45.00 x 2.50= 1.12.5 so 113 miles in 2.50 hours
Answer:
v=0.816 m/s
Explanation:
The force of the spring and the motion of the block are in equilibrium so without any force of friction the motion is


First determinate the constant of the spring that produce the kinetic energy of the bloc



Now the motion with the force of friction in the kinetic


Resolve to v



Answer:
The visible light frequency is 400 THz to 700 THz, approximately. A THz is a Terahertz, which is a unit of frequency equal to one trillion Hertz.
A) Starting from rest, we have the entire cycle determined by 0.8s.
If we assume a constant movement, half of that time is when it reaches the highest point, that is, in 0.4s.
The distance as a function of speed and acceleration is given by,

At the initial point the speed is zero and the acceleration is equivalent to gravity.


B) When returning to the ground, the final speed is zero. Therefore, the equation that relates velocity to acceleration is given by,



All of the above , because it could be all of those answers and etc
