A 0.200-kilogram ball A is traveling at a velocity of 2 meters/second. It hits a 1-kilogram stationary ball B. Which statement i
ioda

As we know that collision is elastic  so we will have

e = 1 = \frac{v_2 - v_1}{2 - 0}

v_2 - v_1 = 2 m/s

also we can use momentum conservation

P_{1i} + P_{2i} = P_{1f} + P_{2f}

0.200(2m/s) + 0 = 0.200 v_1 + 1v_2

0.4 = 0.2v_1 + v_2

now from above two equations we will have

1.2 v_1 = -1.6

v_1 = -1.33 m/s

also we have

v_2 = 0.66 m/s

so both balls will separate after collision and move in opposite direction as the final velocities are opposite in sign

So correct answer will be

<em>D. The balls separate and move in opposite directions.</em>

The outside air pressure changes from 1.0 atm to 1.1 atm. The mass density of mercury is 13,534 kg/m3.By how much does mercury i
mezya [45]

Answer:

The mercury in the barometer rises by a height of 0.0764 m = 76.4 cm = 764 mm

Explanation:

The change in pressure is related to the density of fluid and height risen by the fluid through the relation

ΔP = ρgh

ΔP = change in pressure = P₂ - P₁ = 1.1 - 1.0 = 0.1 atm = 0.1 × 101325 Pa = 10132.5 Pa

ρ = density of the fluid = 13,534 kg/m³

g = acceleration due to gravity = 9.8 m/s²

h = height through which the mercury in barometer rises = ?

10132.5 = 13534 × 9.8 × h

h = (10132.5) ÷ (13534 × 9.8)

h = 0.0763948996 = 0.0764 m = 76.4 cm = 764 mm

Hope this Helps!!!
