Area because CM^2 is the unit used for Area
Answer:
36N
Explanation:
First draw a diagram so you can see which forces act in which direction.
Then define which is your positive direction. I chose the direction of accelleration (downward) to be positive. This means that the weight of the object is also acting in the positive direction but Tension is acting in the negative direction.
If the elevator which contains the object within is accellerating at 2.6 ms^-2 then the object and string system is also accellerating at the same rate.
F = ma where F is the resultant force.
Resultant for is Weight + Tension but tension is in the negative direction so
F = mg -T
F = 5g - T
F = ma so F = 5 x 2.6
13 = 5g-T
T = 5g - 13
T = 36N
(I've taken g = 9.8ms^-2 but if this is for a physics class I'd take it to be 9.81ms^-2)
Answer:
to make a magnet repel a metal, one must first understand the properties of a magnet. A magnet has two poles, a north pole and a south pole. When magnets are placed near each other, opposite poles attract and like poles repel one another.
1. T<span>he fields of science and mathematics are so interdependent because:
</span><span>Scientists need to be able to take careful measurements.
</span><span>Scientists need to be able to make precise measurements.
2. </span>T<span>he following questions can use science as a method of inquiry:
</span><span>How can we protect crops from drought?
</span><span>Did dinosaurs exist?
P.S. </span>No probs man, I will answer the same question over and over again, as long as you are willing to give away so many points. (Would be a real shame if I'm wrong, tho, but let's hope for the best :))
