A car with a mass of 1,000 kg is moving at a speed of 20 m/s. What is the car's kinetic energy?
shtirl [24]

The answer would be 200000 J. the equation for kinetic energy is 1/2 mass times velocity squared. 1/2 of 1,000 is 500. and 20*20 is 400. So, multiply 400 by 500, and that gives you your answer,

An object has a density of 10.00 g/mL. If the object has a volume of<br> 25.00 ml, what is the mass?
SVEN [57.7K]

Answer:

The answer is

<h2>250 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of object = 25 mL

Density = 10 g/mL

The mass of the object is

mass = 25 × 10

We have the final answer as

<h3>250 g</h3>

Hope this helps you

Study the graph in Figure 6.32 and answer to these questions. (see attached image)
Dimas [21]

Hey there :)

We can see that the solubility of salt increases with increasing temperature. This happens with most substances.

To find out the maximum mass of copper sulfate that can be dissolved in water at these temperatures, just interpret the graph.

Considering Y-axis as g copper sulfate/100 g water and the X-axis as the temperature in °C:-

<u>1)</u>

a: <u>0 °C - 14 g of copper sulfate/100 g of water</u>

b: <u>50 °C - 34 g of copper sulfate/100 g of water</u>

c: <u>90 °C - 66 g of copper sulfate/100 g of </u><u>water</u>

<u>2)</u> From the graph, we can infer that temperature affects the solubility of the salt.
