A hydraulic lift has two connected pistons with cross-sectional areas 15 cm2 and 670 cm2. It is filled with oil of density 510 k
BigorU [14]

Answer:

Explanation:

Given

Cross-sectional area of two areas is

A_1=15\ cm^2

A_2=670\ cm^2

It is filled with oil of density \rho _0=510\ kg/m^3

mass of car place on Large area M=1100\ kg

Suppose a mass of m kg is placed on smaller area

According to pascal law's intensity of pressure is same at every point on Liquid

P_1=P_2

\frac{F_1}{A_1}=\frac{F_2}{A_2}

\frac{mg}{15}=\frac{Mg}{670}

m=1100\times \frac{15}{670}

m=24.62\ kg

On a distance-versus-time graph, _____.
babymother [125]

Answer:

A

Explanation:

The slope of the graph has the units of vertical axis divided by horizontal axis. This means that the slope of a distance vs time graph is distance/time, or velocity.

Slope is calculated by "rise over run" so C is incorrect.

Since the slope represents velocity, a constant slope equates to a constant velocity, hence B is incorrect. Same reasoning for D being incorrect: if the slope is zero, the object is not moving.
