Answer:
The use of renewable sources of energy help to solve the problem of energy crisis is discussed below in details.
Explanation:
Environmental and economic advantages of adopting renewable energy incorporate: Creating energy that originates no greenhouse gas discharges from fossil fuels and decreases some kinds of air pollution. Increasing energy stocks and decreasing dependency on shipped fuels.
Here are 5 actionable suggestions you can follow to make a decent utilization of renewable energy on your bases:
- Embrace Solar-Powered Technologies.
- Crowdfund Clean Energy Projects.
- Establish the Society of Concerned Scientists.
Answer:
D, the lithosphere. (CRUST AND UPPER MANTLE)
Explanation:
A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest. Plate thickness also varies greatly, ranging from less than 15 km for young oceanic lithosphere to about 200 km or more for ancient continental lithosphere (for example, the interior parts of North and South America).

Answer:
the work done by the 30N force is 4156.92 J.
For this problem, they don´t ask you to determine the work of the total force applied in the block. They only want the work done for the force of 30N, with an angle of 30º respectively of the displacement and a traveled distance of 160m. So:
W=F·s·cos(α)=30N·160m·cos(30º)=4156.92J
Answer: a) 8.2 * 10^-8 N or 82 nN and b) is repulsive
Explanation: To solve this problem we have to use the Coulomb force for two point charged, it is given by:
Replacing the dat we obtain F=82 nN.
The force is repulsive because the points charged have the same sign.
