I think it’s R=U/I = 120/5 = 24
Because less energy is being wasted. non-renewable resources will last longer.
the cost is kept lower. hope it helps :)
If the acceleration is constant, and the starting velocity is zero, the relationship between the acceleration of a falling body (a), the time it takes to fall (t), and instantaneous velocity when it hits the ground (v) is:
the general equation of acceleration is:
vf = vi + at
assuming the initial velocity (vi) is zero, the equation becomes:
vf = at
v = at
Answer;
All the above
Explanation;
The element carbon is the most important chemical constituent of many organic matter, ranging from fossil fuels to complex molecules such as DNA and RNA, that control genetic reproduction in organisms.
This element is found stored in major sinks found on the earth;
- as organic molecules in living and dead organisms found in the biosphere;
- as the gas carbon dioxide in the atmosphere;
- as organic matter in soils;
- in the lithosphere as fossil fuels and sedimentary rock deposits in the oceans as dissolved atmospheric carbon dioxide and
- as calcium carbonate shells in marine organisms.
Answer:
t = 0.97 s
Explanation:
Given that,
height, h = 4.7 m
We need to find the time taken by the object to fall 4.7 m.
Let it is t. Using second equation of kinematics to solve it such that,
u is initial velocity, u = 0
So,
So, the required time is equal to 0.97 seconds.
