Answer: A, B, and D,
C is incorrect because continental drift takes several centuries to move the tectonic plates witch is not an immediate impact leaving you with A,B, and D.
Think of it this way: If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference. Hope this helps :)
Answer:
Coefficient of static friction = 0.547
Explanation:
The maximum resistive force offered by the body(coin)against the applied force(turntable) to continue its state of motion is called Coefficient Of Static Friction
When given
The angular velocity which is 51.1rpm
We are going to calculate velocity of coin
= r*w(angular velocity) = 0.108*(51.1*2π/60) = 0.58
Coefficient=F/N
F= coefficient* N = coefficient*m*g
F= mv^2/r which is centripetal force
Therefore, mv^2/r = coefficient*m*g
coefficient = mv^2/mgr = v^2/rg
Where g,gravity = 9.81
Substitute into the equation coefficient = 0.58^2/9.81*0.108
= 0.547
I believe the correct answer is "B. Greater".
Answer:
Explanation:
As we know that heat given by the hot piece of iron = heat absorbed by water + ice
As we know that
also we have
now we have
