A particle smaller than an atom or a <span>cluster of such particles </span>
Given the time, the final velocity and the acceleration, we can calculate the initial velocity using the kinematic equation A:

A skateboarder flies horizontally off a cement planter. After a time of 3 seconds (Δt), he lands with a final velocity (v) of −4.5 m/s. Assuming the acceleration is -9.8 m/s² (a), we can calculate the initial velocity of the skateboarder (v₀) using the kinematic equation A.

Given the time, the final velocity and the acceleration, we can calculate the initial velocity using the kinematic equation A:

Answer:

Explanation:
The change in electrical potential energy of a charged particle moving through a potential difference is given by

where
q is the magnitude of the charge of the particle
is the potential difference
In this problem:
- the charge of the particle is 3.00 elementary charges, so

- the potential difference is

So, the change in electrical potential energy is

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.
