Relative motion can best be defined as B<span> the motion of one object as it appears to another object.
An example is when you are in a car the car has the actual motion because it is the one moving but you are also moving because of relative motion.</span>
Answer:
(a) Acceleration = 0.1063 m/s^2 (Second team wins)
(b) Tension in rope = 65.106 N
Explanation:
Total mass of first team = 68 * 9 = 612 kg
Total force of first team = 1350 * 9 = 12150 N
Total mass of second team = 73 * 9 = 657 kg
Total force of seconds team = 1365 * 9 = 12285 N
Difference in force = 12285 - 12150 = 135 N (towards the second team as it has more force)
(a) For acceleration we get:
F = m * a
135 = (mass of both teams) * a
a = 135 / (612 + 657)
acceleration = 0.1063 m/s^2 (Second team wins)
(b) Since we know the acceleration of the first team (pulling being pulled towards the second team at an acceleration of 0.1063 m/s^2) , we can find out the force required to move them:
Force required for first team = mass of first team * acceleration
Force required = 612 * 0.1063
Force required = 65.106 N
This is the force exerted on the first team through the rope, so the tension in the rope will also be 65.106 N.
To help make sure information goes from short-term memory to long-term memory, you can use memory-enhancing strategies. One strategy is rehearsal, or the conscious repetition of information to be remembered. Think about how you learned your multiplication tables as a child.
Proven ways to protect memory include following a healthy diet, exercising regularly, not smoking, and keeping blood pressure, cholesterol, and blood sugar in check. Living a mentally active life is important, too. Just as muscles grow stronger with use, mental exercise helps keep mental skills and memory in tone.
According to one study, mental stimulation like reading can help protect memory and thinking skills, especially as you age. The authors even suggest that reading every day can slow down the late-life cognitive decline. ... The act of reading helps to heighten overall brain function and increase memory.
Let's take a deeper dive into evidence-based exercises that offer the best brain-boosting benefits.
