s2008m [1.1K]

Answer:

63.1 seconds.

Explanation:

Hello!

In this case, since the average adult heart pumps 84.0 mL/s of blood, it means 84.0 mL each second, as we have 5300. mL, the following mathematical set up help us to compute the required time:

$t=5300.mL*\frac{1s}{84.mL}\\\\t=63.1s$

Which is about 1.05 min.

Best regards!

Two shopping carts are pushed with the same force. One cart has a larger mass than the other. How does the mass of the shopping

Harman [31]

This would problem will be answered using the concept of momentum. Momentum is the mass times the velocity, where mass is inversely proportional to the velocity. This would mean that an object with greater mass will travel at a much lesser velocity, or vice versa.

Hence, the cart with the smaller mass will accelerate faster.

Romashka [77]

Answer:

30 μmol/L

Explanation:

A chemist prepares a solution of barium chloride by measuring out 8.9 μmol of barium chloride into a 300mL volumetric flask and filling the flask to the mark with water.

Calculate the concentration in μmol L of the chemist's barium chloride solution. Round your answer to 2 significant digits.

The chemist has 8.9 μmol of solute (barium chloride) and he adds water until the mark of 300 mL in the container, which is the volume of the solution. We will need the conversion factor 1 L = 1000 mL. The concentration of barium chloride in μmol/L is:

$\frac{8.9\mu mol}{300mL} .\frac{1000mL}{1L} =30\mu mol/L$
