Astandard baseball has a circumference of approximately 23 cm. if a baseball had the same mass per unit volume (see tables in section 1-5) as a neutron or a proton, about what would its mass be?

The mass of A standard baseball is 1.13.10¹⁵ kg

The ball is a 3-dimensional space constructed by many circles of the same diameter and has the same center point

Protons and neutrons are basic particles forming atoms of other than electrons

The mass of 1 proton is equal to the mass of 1 neutron, equal to 1 atomic mass unit and electrons have a mass smaller than both.

electron mass = 9.11.10 g

proton mass = 1.6726.10⁻²⁴ g

neutron mass = 1,675.10⁻²⁴ g

While

Because the diameter of the proton is unknown then we use it from sources on the internet obtained = 0.84.10⁻¹⁵ m

proton radius = 4.2.10⁻¹⁶ m

ball radius = 23 / 2π

ball radius = 3.6624 cm = 3.6624.10⁻² m

From the above question shows the density of the proton = density of the ball to find the mass of the ball,

so we can compare them (protons are considered like balls)

proton density = ball density

m ball = 1.13.10¹⁵ kg

volleyball players can not touch the net while the ball is in play

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
