The kinetic energy (in joules ) of a moving object can be calculated from the expression 1/2mv to the second power, where m is t

yulyashka [42]

E = 1/2 m v^2

E = 1/2 (0.145) (40)^2

E = 0.0725 x 1600

E = 116 kg m^2/s^2

1 joule = 1 kg m^2/s^2

so here E in joules is 116 joules

so E = 116 joules

To find the density:

⇒ must find the relationship between the density, mass, and volume

⇒ $Density = \frac{mass}{volume}$

Let's examine the information given:

weight: 1890g
dimensions: 8cm * 5cm* 5cm

Let's first find the volume:

⇒ the volume is the dimensions multiplied together

$Volume = 8cm * 5cm * 5cm = 200cm^3$

LEt's calculate the density now:

$Density = \frac{1890g}{200cm^3} =9.45g/cm^3$

Answer: The density of the copper is 9.45g/cm^3 or Choice (A)

Hope that helps!

Which is an equation of the line that passes through the points (5, 2) and (10, -3)?

sashaice [31]

Answer:

y = -x + 7

Step-by-step explanation:

Hi there!

We are given the following points:
(5,2) and (10,-3)

We want to find the equation of the line that passes through these 2 points

There are 3 ways to write the equation of the line, yet the most common way is slope-intercept form, which is y=mx+b (m is the slope and b is the y intercept).

First, let's find the slope of the line.

The slope can be calculated from 2 points using the equation $\frac{y_2-y_1}{x_2-x_1}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points

We have everything we need to find the slope, but let's label the values of the points to avoid confusion and mistakes.

$x_1=5\\y_1=2\\x_2=10\\y_2=-3$

Now substitute these values into the formula to find the slope

m= $\frac{y_2-y_1}{x_2-x_1}$

m= $\frac{-3-2}{10-5}$

Simplify

m= $\frac{-5}{5}$

Divide

m=-1

The slope of the line is -1

We can substitute this value as m in y=mx+b.

Here's the equation of our line so far:

y=-x+b

Now we need to find b

As the equation passes through the points (5,2) and (10,-3), we can use either point to find the value of b

Taking (5,2) for example:

Substitute 5 as x and 2 as y

2=-5+b

Add 5 to both sides

7=b

Substitute 7 as b in the equation

y = -x + 7

Hope this helps!
