7 0

Answer: 120N

Explanation:

Given variables are:

force needed = ?

mass of object = 60 kg

acceleration = 2.0 m/s²

Since the magnitude of force depends on the mass of the object and the acceleration by which it moves.

i.e Force = mass x acceleration

Force = 60 kg x 2.0 m/s²

Force = 120 N

Thus, 120 Newton of force is needed to make 60 kg object accelerate at a rate of 2.0 m/s²

Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under
Radda [10]

Answer:

O Charles's law .

Explanation:

Hello!

In this case, since the use of gas laws leads to a good comprehension of how gases behave towards volume, pressure and temperature, we can review that the Boyle's law explains the pressure-volume variation, the Dalton's law the partial pressure effect, the Gay-Lussac's law that of pressure and temperature and the Charles' that of temperature and volume at constant pressure; thus, the answer for the asked question is:

O Charles's law

100.0 mL of a 0.500 M solution of KBr is diluted to 500.0 mL. What is the new concentration of the solution
andreyandreev [35.5K]

Answer:

0.1 M

Explanation:

The following data were obtained from the question:

Initial volume (V1) = 100 mL

Initial concentration (C1) = 0.5 M

Final volume (V2) = 500 mL

Final concentration (C2) =?

Using the dilution formula C1V1 = C2V2, the new concentration of the solution can be obtained as follow:

C1V1 = C2V2

0.5 × 100 = C2 × 500

50 = C2 × 500

Divide both side by 500

C2 = 50/500

C2 = 0.1 M

Therefore, the new concentration of the solution is 0.1 M
