U = m * g * h
350 = 17 * 9.8 * h
h = 350 / 166.6
h = 2.10
Nearest whole number = 2.00
In short, Your Answer would be 2 meter
Hope this helps!
Answer:
Explanation:
Since the surface is frictionless therefore there will be no friction force on block but there will be weight of block which we can divide in to two components i.e. mgcosθ &mgsinθ which is perpendicular and parallel to the surface respectively.
In response to mgcosθ ramp will apply a normal force to the block which will be of equal magnitude to that of mgcosθ.
Therefore Ramp will apply a Force of mgcosθ on block where m is the mass of block.
Answer:
Answer
Explanation:
The very first generation of star systems in the universe probably consisted only of hydrogen and helium. This means that,
There were no comets or asteroids in these first-generation star systems. As the comets and asteroids were the only soruce of elements other than Hydrogen and Heliums ( As starts mainly consists of helium and hydrogen).
The characteristics of stars that can be determined by analyzing a star's spectrum - Doppler shift, temperature, size, composition, and rotation.
1- Rotation: The star's rotation creates a broadening of the spectral lines, which can be used to determine the star's rotation.
2- Temperature: Measure the relative strengths of spectral lines to determine a star's spectral class which corresponds to temperature.
3- Doppler shift: The Doppler shift of the star is determined by its radial velocity.
4- Size: Measure the width of spectral lines. If the lines are narrow, the star's diameter is large. If the lines are wider, the star's diameter is smaller.
5- Composition: Computer models and temperature are used to determine elemental abundances from relative strengths of absorption lines in a star's spectrum.

2nd stone time = 13.0/9.8 = 1.33 seconds
distance = 0.5*9.8*1.33^2 = 8.67 meters
1st stone time = 1.33+1.5 = 2.83 seconds
distance = 0.5*9.8*2.83^2 = 39.24 meters
39.24-8.67 = 30.57 meters apart
