Hey, I need help can someone help me out, please?

Answer:

the answer is b temperature

Answer:

[tex]\boxed {\boxed {\sf v \approx 33.088 \ mL}}[/tex]

Explanation:

The formula for density is:

[tex]d= \frac{m}{v}[/tex]

where m is the mass and v is the volume.

The mass is 0.45 kilograms and the density is 13.6 grams per milliliter. The density is given in grams, so we must convert the mass.

There are 1000 grams in 1 kilogram or [tex]\frac{1000 \ g} {1 \ kg}[/tex]. We can multiply the mass by this ratio.

[tex]0.45 \ kg * \frac{1000 \ g} {1 \ kg} = 0.45 * 1000 \ g = 450 \ g[/tex]

Now we have values for the mass and density:

[tex]13.6 \ g/mL =\frac{450 \ g}{ v}[/tex]

Cross multiply.

[tex]\frac {13.6 \ g/mL}{1} =\frac{450 \ g}{ v}[/tex]

[tex]13.6 \ g/mL * v=450 \ g * 1 \\13.6 \ g/mL * v=450 \ g[/tex]

We are trying to find the volume, so we must isolate that variable.

13.6 and v are being multiplied. The inverse of multiplication is division. Divide both sides by 13.6

[tex]\frac {13.6 \ g/mL*v } { 13.6 \ g/mL} = \frac{ 450 \ g} {13.6 \ g/mL}[/tex]

[tex]v= \frac{ 450 \ g} {13.6 \ g/mL}[/tex]

The grams will cancel.

[tex]v= 33.0882353 \ mL\\v \approx 33.088 \ mL[/tex]

The volume is about 33.088 milliliters.

Answer: 21 kg x m/s

Momentum can be found using the equation p = mv, or momentum = mass times velocity.

Therefore, to find the momentum of the bowling bowl, you can plug the mass and velocity values into the equation to get p = (7kg)(3m/s)

Solve the equation to get a momentum of 21kg x m/s

I hope I could help :)
