Answer:
As an object moves faster, its mass increases. ... Because masses approach infinity with increasing speed, it is impossible to accelerate a material object to (or past) the speed of light. To do so would require an infinite force.
Expectations relate to future schooling by choosing classes that are at your skill level.
Answer: Option B
<u>Explanation:
</u>
Each individual has a different set of skills blessed by the Mighty and each should enhance them according to his/her will and interest. For the future prospects of schooling and teaching, there is one noticeable point to be acted is that students should not be forced to study the subject beyond their skills and capability.
We should remember that a fish cannot fly and a bird cannot swim. They both cannot be trained under the same study programmes. Although they both can know how to swim and fly but it’s their capability and interest over the subjects that can lead them further to rule over either the sky or the oceans.
So, the future school programming should be done in such a way that individuals have an authority to choose their subjects accordingly and learn more about their skills.
A free body diagram is a diagram showing all of the forces acting on a system. It shows the relative magnitude and direction of each of the forces. Is that what you're looking for? I don't fully understand what you're asking
Answer:
The minimum power the motor would need is 2035 Watts.
Explanation:
the minimum power motor needed is given by the total work done on the load, Wtot and the total time it takes the load to be lifted, given by:
P = Wtot/t
the forces doing works on the load is the gravitational force, Wfg and the frictional force, Wf the total work done on the load is:
Wtot = Wfg + Wf
= m×g×d + f×d
= d×(m×g + f)
= (30)×(200×9.8 + 75)
= 61050 J
it takes t = 30s for the load to be lifted high the building, the minimum power neeed is then:
P = Wtot/t
= (61050)/(30)
= 2035 Watts
Therefore, the minimum power the motor would need is 2035 Watts.
A force that cannot produce equilibrium with these two forces must be less than 7 N or greater 7 N.
The given parameters;
- <em>3 Newton force </em>
- <em>4 Newton force</em>
A body is said to be in equilibrium state when the net force on the body is zero.
A force that produce equilibrium among two forces acting concurrently is known as equilibrant force. This force is usually equal to sum of the two concurrent forces.
where;
- F₁ and F₂ are the concurrent forces
- F₃ is the equilibrant force
From the given parameters;
Thus, a force that cannot produce equilibrium with these two forces must be less than 7 N or greater 7 N.
