Answer:
Height reached will be 28.35 m
Explanation:
Here we can use the work energy theorem to find the maximum height
As we know by work energy theorem
Work done by gravity + work done by friction = change in kinetic energy
![-mgh - F_f h = 0 - \frac{1}{2}mv_i^2](https://tex.z-dn.net/?f=-mgh%20-%20F_f%20h%20%3D%200%20-%20%5Cfrac%7B1%7D%7B2%7Dmv_i%5E2)
now we will have
![-1.60(9.8)(h) - 0.900(h) = - 470](https://tex.z-dn.net/?f=-1.60%289.8%29%28h%29%20-%200.900%28h%29%20%3D%20-%20470)
![-16.58 h = -470](https://tex.z-dn.net/?f=-16.58%20h%20%3D%20-470)
![h = 28.35 m](https://tex.z-dn.net/?f=h%20%3D%2028.35%20m)
so here the height raised by the stone will be 28.35 m from the ground after projection in upward direction
D. The molecules in water are constantly moving.
They are able to do this because they move around to take whatever shape of the container.
Answer:
The temperature is 90.4°C
Explanation:
See the attached for explanation
When an object's atoms move faster, its thermal energy increases and the object becomes warmer.
Wavelength = (speed) / (frequency)
Wavelength = (300 thousand km per second) / (10.5 billion per second)
Wavelength = (300 / 10.5) (thousand km per second) / (billion per second)
Wavelength = (28.57) (million meters / second) / (thousand million / second)
Wavelength = (28.57) (meters / second) / (thousand / second)
Wavelength = (28.57) (meters / thousand)
<em>Wavelength = (28.57) (millimeters) </em>
