The force required to push the box upward is 145.3N and the force to pus the box downward is -109.3N
Data given;
- mass = 15kg
- angle = 30 degree
- acceleration = 1.2 m/s^2
- acceleration due to gravity = 9.8 m/s^2
<h3>Force against gravity</h3>
To move the plane upward, the box will move against gravity.
Let's solve for F
<h3>Force towards gravity</h3>
When the force pushes the box down the inclined plane, it moves towards gravity.
The force required to push the box upward is 145.3N and the force required to push the box downward is -109.3N

I think the correct answer from the choices listed above is option D. Scientists would use a control sample that has no dna from bighead carp in edna surveillance in order to to verify that no dna has contaminated the gel. It would eliminate certain errors in the experiment.
Answer:
748 treats.
Explanation:
If the trainer gives out 34 treats and gave them out for 22 shows, then to find the total you need to multiply 34 by 22, or (a longer but more simple way) add 34, 22 times.
Answer:
Explanation:
masie m = 20g = 20/1000 = 0.02kg
prędkość v = 50m/s
P.E = K.E = ½mv²
P.E = ½ × 0.02 × 50²
P.E = 25 J
pracę wykonana = P.E = 25J
