A girl has a weight of 450 N and her feet have a total area of 300Cm2

snow_tiger [21]

Answer:

15000N/m²

Explanation:

Given parameters:

Force exerted by the girl = 450N

Area = 300cm²

Unknown:

Pressure exerted by her feet =?

Solution:

Pressure is the force per unit area on a body;

Pressure = $\frac{force }{area}$

We need to convert the given area to m²;

10000cm² = 1m²

300cm² = $\frac{300}{10000}$ = 0.03m²

Pressure = $\frac{450}{0.03}$ = 15000N/m²

A student makes a compound of sulfur and oxygen. She uses 5.00 g of sulfur and 4.99 g of oxygen, and all of the elemental substa

victus00 [196]

First, we apply the law of conservation of mass which states that the total mass in a system remains constant.
Therefore, there must be 5.00 g of sulfur and 4.99 g of oxygen in the product. Now, we determine the mass percentage using:

Mass % = (mass of sulfur x 100) / total mass of compound

Mass % = (5 * 100) / (5 + 4.99)

Mass % = 50.05%

The product contains 50.05% sulfur by mass.
