Alisiya [41]

Density = 0.601 g/mL

Volume = 7.25 mL

D = m / V

0.601 = m / 7.25

m = 0.601 x 7.25 => 4.35725 g

hope this helps!

You push a shopping cart for fun with a force of 60N. If the shopping cart has a mass of 12kg, what is the acceleration on the c

ivann1987 [24]

Answer:

$\boxed {\boxed {\sf 5 \ m/s^2 }}$

Explanation:

We are asked to find the acceleration of a shopping cart, given the force and mass. According to Newton's Second Law of Motion, force is the product of mass and acceleration.

$F= m \times a$

The mass of the shopping cart is 12 kilograms and the force is 60 Newtons. Let's convert the units for force. 1 Newton is equal to 1 kilogram meter per second squared, so the force of 60 Newtons is also 60 kilogram meters per second squared.

F= 60 kg*m/s²
m= 12 kg

Substitute the values into the formula.

$60 \ kg *m/s^2 = 12 \ kg \times a$

We are solving for the acceleration, so we must isolate the variable a. It is being multiplied by 12 kilograms. The inverse operation of multiplication is division, so we divide both sides by 12 kg.

$\frac {60 \ kg *m/s^2 } { 12 \ kg}= \frac{12 \ kg \times a }{12 \ kg}$

$\frac {60 \ kg *m/s^2 } { 12 \ kg}=a$

The units of kilograms cancel.

$\frac {60 \ m/s^2 } { 12 }=a$

$5 \ m/s^2 =a$

The acceleration of the shopping cart is <u>5 meters per second squared.</u>

Keith_Richards [23]

Answer:

It is important because it separates the area that the process is happening from its surroundings, and it's easy to measure and make observations by doing that.

Explanation:

The system is the part of the universe that is separated for study. It has a frontier, which is the limitation of it, and the external area is the surroundings.

In the system the chemical and physical process is happening: reactions are taking place, gas is expanding, heat is being absorbed or lost, etc.

So, to understand the process that is happening, it's necessary to define the system under study because the measurements, analyze, and observation will be easily done.
