The density of the baseball is $0.875 g/cm^3$

Explanation:

The density of an object is given by the equation

$d=\frac{m}{V}$

where

m is the mass of the object

V is its volume

For the baseball in this problem, we have:

m = 350 g is its mass

$V=400 mL = 400 cm^3$ is the volume

Substituting into the equation, we find the density:

$d=\frac{350}{400}=0.875 g/cm^3$

Therefore, the ball's density is outside the acceptable range.

$F=342.9+32$

$F=374.9$

$374.9F=190.5C$

A 30,000-kg freight car is coasting at 0.850 m/s with negligible friction under a hopper that dumps 110,000 kg of scrap metal in

erica [24]

Explanation:

Given that,

Mass of a freight car, $m_1=30,000-kg$

Speed of a freight car, $u_1=0.85\ m/s$

Mass of a scrap metal, $m_2=110,000\ kg$

(a) Let us assume that the final velocity of the loaded freight car is V. The momentum of the system will remain conserved as follows :

$30000\times 0.85=(30000+110000)V\\\\V=\dfrac{30000\times 0.85}{30000+110000}\\\\=0.182\ m/s$

So, the final velocity of the loaded freight car is 0.182 m/s.

(b) Lost on kinetic energy = final kinetic energy - initial kinetic energy

$\Delta K=\dfrac{1}{2}[(m_1+m_2)V^2-m_1u_1^2)]\\\\=\dfrac{1}{2}\times [(30,000+110,000 )0.182^2-30000(0.85)^2]\\\\=-8518.82\ J$

Lost in kinetic energy is 8518.82. Negative sign shows loss.

Sally goes on a hike. The distance she walks compared to the amount of time she walks is shown on the graph. Which statement is

Neko [114]

According to the task there should be the graph that supports Sally's hike, but after looking on the options it seems that Sally doesn't walks at a constant rate and there is the negative option that coincides with my thoughts. So, I bet the false statement is the third option represented in the scale above.
