Answer:
a) the distance the ball moves up the ramp is approximately 9.35 meters
b) the tme required for the ball to return to the girls' hands is 6.34 seconds
Explanation:
The movement of the ball can be describe by a rectilinear movement with constant (negative) acceleration of 0.19 g = 1.862 m/s^2
Therefore the kinematic equations for the case the girl launches the ball at 5.9 m/s, we can write:
We use the second equation above to find the time it takes for the velocity to reduce to zero (and start the movement back down the ramp), and then use the time found to calculate the distance;
We use this time to find the distance the ball moves up the ramp:
so the distance the ball moves up the ramp is approximately 9.35 meters
The ball will return to the hands of the girl in the double of the time it took to reach the max distance, that is 2 times 3.17 sec = 6.34 sec
Answer:
At constant pressure
Explanation:
Enthalpy of a system may be defined as the system's internal energy in addition to the product of the volume and pressure of the system.
It can be regarded as the system's capacity of heat transfer and to do non- mechanical work.
The enthalpy of the system at constant pressure gives the amount of heat or energy that is either absorbed by the system or released by the system.
Answer:
If a chord had notes with frequencies of 100, 1,000, and 6,000 Hz, the basilar membran would vibrate at multiple positions, with peaks at A, B, and C.
