Do you support trucks are identical each box loaded on the truck has the same mask choose the truck that has the greatest force
of gravity acting on it?helpppppp
1 answer:
gravitational force of earth is given by
so here the force will depend on the product of mass and gravity
so here force will be more if we took the condition of more masses
so here in 3rd figure
there will be maximum force of gravity on it
because it will have 6 boxes so there will be maximum mass
So figure of truck with 6 boxes on it is correct answer

Answer:
dr/dt = -2 cm/s.
Explanation:
The volume of a cone is given by:
(1)
- r is the radius
- h is the height
Let's take the derivative with respect to time in each side of (1).
(2)
We know that:
- dh/dt = 10 cm / s (rate increasing of height)
- dV/dt = 0 (constant volume means no variation with respect of time)
- r = 4 cm
- h = 10 cm
We can calculate how fast is the radius changing using the above information.
Therefore dr/dt will be:
The minus signs means that r is decreasing.
I hope it helps you!
