A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it

Marina86 [1]

Answer:

Density of rock will be equal to $3.13g/cm^3$

Explanation:

It is given that mass of the rock $m=260gram$

Volume displaced bu rock $V=83cm^3$

We have to find the density of rock

Density is equal to ratio of mass and volume

Therefore density of rock $\rho =\frac{m}{V}$

$\rho =\frac{260}{83}=3.13g/cm^3$

So density of rock will be equal to $3.13g/cm^3$

A 6.0 kg bowling ball moving at 3.5m/s to the right makes a collision, head-on, with a stationary 0.70 kg bowling pin. If the ba

devlian [24]

Answer:

The velocity of the pin will be 6.26 m/s in the right direction.

Explanation:

Let's use the momentum conservation equation.

$p_{i}=p_{f}$

Initially, we have:

$p_{i}=m_{b}*v_{ib}$

Where:

m(b) is the ball mass
v(ib) is the initial velocity of the ball

Now, the final momentum will be:

$p_{f}=m_{b}*v_{fb}+m_{p}*v_{fp}$

Where:

m(p) is the pin mass
v(fb) is the final velocity of the ball

v(fp) is the final velocity of the pin

Then, using the equation of the conservation we have:

$m_{b}*v_{ib}=m_{b}*v_{fb}+m_{p}*v_{fp}$

$6*3.5=6*2.77+0.7*v_{fp}$

$v_{fp}=6.26 m/s$

Therefore the velocity of the pin will be 6.26 m/s in the right direction.

I hope it helps you!
