Answer:
0 J
Explanation:
If it's at the same temperature then it doesn't need more heat. So it'd be 0 J since it's already at 0C.
(a) The initial vertical velocity of the stone is 16.85 m/s and the initial horizontal velocity is 14.14 m/s.
(b) The final vertical velocity is 0 and the final horizontal velocity is 14.14 m/s.
<h3>
Initial vertical velocity</h3>
The initial vertical velocity of the stone is calculated as follows;
Vi = Vsinθ
Vi = 22 x sin(50)
Vi = 16.85 m/s
<h3>Initial horizontal velocity</h3>
Vxi = V cosθ
Vxi = 22 x cos(50)
Vxi = 14.14 m/s
<h3>Final vertical velocity of the stone</h3>
Vf = Vi - gt
where;
- Vf is the final vertical velocity = 0 at maximum height
<h3 /><h3>Final horizontal velocity of the stone</h3>
Vfx = Vxi = 14.14 m/s
Thus, the initial vertical velocity of the stone is 16.85 m/s and the initial horizontal velocity is 14.14 m/s.
The final vertical velocity is 0 and the final horizontal velocity is 14.14 m/s.

Answer:
Frequency, f = 0.2 Hz
Explanation:
We have,
A baseball player throws 4 balls every 20 seconds.
It is required to find the frequency of the baseball.
Frequency of an object is defined as the number of times an event occurs. It is given by number of throws per unit time. It can be given by :
So, the frequency of his throw is 0.2 Hz.
Answer:
the formula given out a Distance x force you get work done
Answer:
306.08 kPa
Explanation:
Given data
Average stress of first wave = 3811 kPa
amplitude of first wave ( A1 ) = 430 kPa
Frequency of first wave = 6 Hz
<u>Determine the average stress of the second sinusoidal component in kPa </u>
Amplitude of the additional wave (A2add) = = 430 / 2 = 215 kPa
next we will determine the resultant amplitude of the second wave
A2 =
=
=
= = 480.79
hence the average stress of the second sinusoidal component
=
= = 306.08 kPa
