The kinetic energy of a ball with a mass of 0.5kg and a velocity of 10 m/s is ?
KATRIN_1 [288]

Answer:

K.E = 25 J

Explanation:

Given data:

Mass of ball = 0.5 g

Velocity of ball = 10 m/s

Kinetic energy = ?

Solution:

Formula:

K.E = 1/2 mv²

m = mass

v = velocity

Now we will put the values in formula.

K.E = 1/2 mv²

K.E = 1/2× 0.5kg × (10m/s)²

K.E = 1/2 ×0.5kg × 100m²/s²

K.E = 25 Kg.m²/s²

Kg.m²/s² = J

K.E = 25 J

A solution of aqueous ammonium sulfate has a mass of 482 grams. Calculate the mass of ammonium sulfate in solution if the mass p
umka2103 [35]

Answer:

The answer to your question is the mass of solute = 53.5 g

Explanation:

Data

mass of solution = 482 g

mass of solute = ?

mass percent = 11.1 %

Mass percent is a unit of concentration. It measures the mass of the solute divided by the total mass of the solution

Process

1.- Write the formula

        Mass percent = mass of solute / mass of solution x 100

-Solve for mass of solute

          mass of solute = Mass percent x mass of solution / 100

2.- Substitution

          mass of solute = 11.1 x 482 / 100

3.- Simplification

          mass of solute = 5350.2 / 100

4.- Result

          mass of solute = 53.5g
