Given parameters:
Initial velocity of eraser = 5.0m/s
Time = 7.0s
Unknown:
Final velocity = ?
Solution:
Since we have been given the initial velocity and duration of the throw, we can apply the appropriate motion equation to solve this problem.
V = U - 2gt
where V is the final velocity
U is the initial velocity
g is the acceleration due to gravity = 9.8m/s²
t is the time taken
V = U - gt
V = 5 - (9.8)(7)
V = -63.6 or -64m/s
The velocity is -64m/s
Hi the answer is cumulonimbus clouds. Hope this helps.
When the core temperature rises, stars start burning helium to carbon. Hydrogen and helium are fused in a shell surrounding the core, raising the temperature.
The most prevalent method of generating energy in the cosmos is hydrogen fusion. The gravitational force is utilised to fuse hydrogen at the centres of our Sun and other stars, where it has a density more than 70 times greater than that of steel. Thus, all of the heat and light on earth comes from fusion. Helium is a chemical element with the atomic number 2 and the symbol He. The first member of the noble gas group in the periodic table, it is a colourless, odourless, tasteless, inert, monatomic gas that is not harmful.

Answer:
3600
Explanation:
90 of 120 is 3/4 so 4800 - 1200 is 3600.
