stepan [7]

The unit of measurement is best to estimate the volume of a juice box will be kilogram.

<h3>What is volume?</h3>

The capacity of a container like how much quantity of liquid can be filled in that container is called the volume.

The juice bottle is estimated by liter as it contains the liquid. The juice box is a solid cardboard with some volume into which juice bottles are kept. So, the weight will be shown in kilograms.

Thus, the unit of measurement is best to estimate the volume of a juice box will be kilogram.

In the design of a supermarket, there are to be several ramps connecting different parts of the store. Customers will have to pu
tatuchka [14]

Answer:

3.90 degrees

Explanation:

Let g= 9.81 m/s2. The gravity of the 30kg grocery cart is

W = mg = 30*9.81 = 294.3 N

This gravity is split into 2 components on the ramp, 1 parallel and the other perpendicular to the ramp.

We can calculate the parallel one since it's the one that affects the force required to push up

F = WsinΘ

Since customer would not complain if the force is no more than 20N

F = 20

294.3sin\theta = 20

sin\theta = 20/294.3 = 0.068

\theta = sin^{-1}0.068 = 0.068 rad = 0.068*180/\pi \approx 3.90^0

So the ramp cannot be larger than 3.9 degrees
