Answer:
h = 11.47 m
Explanation:
Initial speed pf the t-shirt gun is 15 m/s
We need to find the maximum distance covered by the t-shirt. It is based on the conservation of energy. The maximum distance covered is given by :
![h=\dfrac{u^2}{2g}\\\\h=\dfrac{(15)^2}{2\times 9.8}\\\\h=11.47\ m](https://tex.z-dn.net/?f=h%3D%5Cdfrac%7Bu%5E2%7D%7B2g%7D%5C%5C%5C%5Ch%3D%5Cdfrac%7B%2815%29%5E2%7D%7B2%5Ctimes%209.8%7D%5C%5C%5C%5Ch%3D11.47%5C%20m)
So, it will cover a distance of 11.47 m.
Answer:
Equilibrium. • When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero.
<span>c. low frequency and low energy</span>
Explanation:
Fgravity = G*(mass1*mass2)/D²
G is the gravitational constant throughout the universe.
D is the distance between the 2 objects.
the distance is now quadrupled.
Fgravitynew = G*(mass1*mass2)/(4D)² =
= G*(mass1*mass2)/(16D²) =
= (G*(mass1*mass2)/D²) / 16 = Fgravity/16
the new gravitational force will be 179/16 = 11.1875 units
No
Explanation:
Tap water will not boil and freeze at those exact temperature which are the boiling and freezing points.
O°C and 100°C are the boiling points of pure water.
Pure water is a pure substance with a definite composition made up of 2 atoms of hydrogen and 1 atom of oxygen.
Pure water boils at 100°C and freezes at O°C ,
- Tap water is not pure water.
- It has some impurities in it which causes causes the elevation of the boiling point of liquids and widening of the boiling range.
- Tap water is treated water that contains some other dissolved chemicals.
