The acceleration of a sprinter is 10 m/s2. The force exerted on the starting blocks is 650 N. What is the mass of the sprinter?

jek_recluse [69]

The relation between force, mass of an object and its acceleration is given by following equation

F = mass of object X acceleration

The unit of Force is Newton (N)

unit of acceleration is ms⁻²

unit of mass if Kg

[all these are SI units]

Mass of object = $\frac{Force}{acceleration}$

mass of sprinter = $\frac{650}{10}=65kg$

A sample of air at 58.6 kPa is expanded from 250 mL to 655 mL. If thetemperature remains constant, what is the final pressure in

kati45 [8]

Answer:

Explanation:

The final pressure can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we are finding the final pressure

$P_2 = \frac{P_1V_1}{V_2} \\$

From the question

58.6 kPa = 58600 Pa

We have

$P_2 = \frac{58600 \times 250}{655} = \frac{14650000}{655} \\ = 22366.4122... \\ = 22366$

We have the final answer as
