12kN is equal to 12000 N
and the perpendicular component will be
[email protected] mg = 12000 N
cos10°= 0.984
thus it will be 12000*0.984 = 11808N
the frictional force will be
[email protected]sin10° = 0.1736
and hence it will be = 2083N
Answer:
No it can not
Explanation: Kinetic energy is the energy of motion so it can not be negative the kinetic energy can only be at a point of "0" which is when its not moving. (I hope this helped) :))
When conducting a hypothesis test there are two possible decisions that you can make: reject the null hypothesis or fail to reject the null hypothesis.
A statistical hypothesis test is a method of statistical inference used to decide whether the data at hand sufficiently support a particular hypothesis. Hypothesis testing allows us to make probabilistic statements about population parameters.
When conducting a hypothesis test there are two possible decisions: reject the null hypothesis or fail to reject the null hypothesis. You should remember though, hypothesis testing uses data from a sample to make an inference about a population. When conducting a hypothesis test we do not know the population parameters. In most cases, we don't know if our inference is correct or incorrect.
When we reject the null hypothesis there are two possibilities. There could really be a difference in the population, in which case we made a correct decision. Or, it is possible that there is not a difference in the population (i.e., is true) but our sample was different from the hypothesized value due to random sampling variation. In that case we made an error. This is known as a Type I error.
When we fail to reject the null hypothesis there are also two possibilities. If the null hypothesis is really true, and there is not a difference in the population, then we made the correct decision. If there is a difference in the population, and we failed to reject it, then we made a Type II error.

The DNA chain is 364 times smaller than the complex virus.
<h3>
How small if the DNA chain?</h3>
The size of the DNA chain is calculated as follows;
relative size of DNA chain = size of complex virus/size of DNA chain
relative size of DNA chain = 171 mm / 0.47 mm
relative size of DNA chain = 363.83 = 364
Thus, the DNA chain is 364 times smaller than the complex virus.

So, the force of gravity that the asteroid and the planet have on each other approximately
<h3>Introduction</h3>
Hi ! Now, I will help to discuss about the gravitational force between two objects. We already know that <u>gravitational force occurs when two or more objects interact with each other at a certain distance and generally orbit each other to their center of mass</u>. For the gravitational force between two objects, it can be calculated using the following formula :
With the following condition :
- F = gravitational force (N)
- G = gravity constant ≈
N.m²/kg² 
= mass of the first object (kg)
= mass of the second object (kg)- r = distance between two objects (m)
<h3>Problem Solving</h3>
We know that :
- G = gravity constant ≈ N.m²/kg²
- = mass of the first object =
kg. - = mass of the second object =
kg. - r = distance between two objects =
What was asked :
- F = gravitational force = ... N
Step by step :
<h3>Conclusion</h3>
So, the force of gravity that the asteroid and the planet have on each other approximately
