Answer:
a)27.3N
b)150.78N
Explanation:
Having in mind the conservation of energy, as the monkey goes up (gaining potential gravitational energy) the kinetic energy must be reduced, so reducing the velocity of the monkey. So the maximum velocity will be at this lower point with a velocity of 1.36m/s
From this velocity and the radius we can calculate the angular velocity for the monkey center of mass:
with this we can calculate the centripetal force magnitude:
On the mokey center of mass we have two opposite forces acting, the tension of the arm and the weight, in order for the monkey to continue swinging the resolt of this two forces must be equal to the centripetal force:
I think it is B because it seems like the most valid choice.
The best answer would be:
B. Epi pen
Here is more about it:
An epi pen injects epinephrine into the body to counteract the effects of an allergic reaction. Epinephrine helps narrow blood vessels and open up the airways. This can be used for food allergies, insect bites, and some other allergens. It is very effective and immediately works, but it is short-lived, so seeking medical attention after is still needed.
Answer:
Explanation:
As we know by the principle of uncertainty that the product of uncertainty in position and uncertainty in momentum is given as
so here we know that
so we have
Answer:
Work = F * s where s is the distance F moves
Since F is stationary, in this case, "no work" is done by either person
