Answer:
F = 1480.77N
Explanation:
In order to calculate the required force to push the container with a constant velocity, you take into account the the sum of force on the container is equal to zero. Furthermore, you have for an incline the following sum of forces:
(1)
F: required force = ?
W: weight of the container = 1800N
N: normal force = weigth
α: angle of the incline = 28°
g: gravitational acceleration = 9.8m/s^2
μ: coefficient of friction = 0.4
You solve the equation (1) for F and replace the values of the other parameters:
The required force to push the container for the incline with a constant velocity is 1480.77N
I believe the answer is "The new theory is an explanation accepted worldwide."
The electric field strength will be 0.6252 V/m. It is the strength at which the field is created by charges.
<h3>What is electric file strength?</h3>
The electric field strength is defined as the ratio of electric force and charge.
The electric field strength is found as;
Hence, the electric field strength will be 0.6252 V/m.

The correct answer is - D. 1 percent.
The United States are the biggest consumer of electricity in the world. Because of that the United States are using multiple different sources in order to satisfy the demand for the electricity. The solar energy though accounts for only 1% of the total amount of produced electricity in the country and that is concerning. The biggest concern of course is the environmental one as the majority of the electricity is produced by sources that are polluting the environment. The other concern is that the United States are not using their potential in gaining more electricity from the solar radiation when taken in account that they have very large areas in the country that have a lot of intense solar radiation and clear skies throughout most of the year.
