<h2>Density of the unknown liquid is 771.93 kg/m³</h2>

Explanation:

An empty graduated cylinder weighs 55.26 g

Weight of empty cylinder = 55.26 g = 0.05526 kg

Volume of liquid filled = 48.1 mL = 48.1 x 10⁻⁶ m³

Weight of cylinder plus liquid = 92.39 g = 0.09239 kg

Weight of liquid = 0.09239 - 0.05526

Weight of liquid = 0.03713 kg

We have

        Mass = Volume x Density

        0.03713 = 48.1 x 10⁻⁶ x Density

        Density = 771.93 kg/m³

Density of the unknown liquid is 771.93 kg/m³

A large cube (mass = 25 kg) being accelerated across a horizontal frictionless surface by a horizontal force . A small cube mass
belka [17]

Answer:F=400.28 N

Explanation:

Given

mass of large cube M=25 kg

mass of small cube m=4 kg

coefficient of static friction \mu =0.71

acceleration a of the system is given by

F=(M+m)a

a=\frac{F}{M+m}

Now Normal reaction between two blocks is given by

N=ma

friction tries to balance weight

thus f_r=mg

and f_r=\mu N

f_r=\mu ma

\mu ma=mg

\mu \frac{F}{M+m}=g

F=\frac{(M+m)g}{\mu }

F=\frac{29\times 9.8}{0.71}

F=400.28 N

Which of the following capacitor can store more data in DRAM?
Neko [114]

Answer:

Stacked - Cell

Explanation:

DRAM is an acronym that means Dynamic Random access memory. It is a type of random access semiconductor memory that stores it's data in a memory cell where a tiny capacitor and a transistor are.

A Trench Capacitor, or otherwise called Deep Trench Capacitor(DTC). They can store only between 4 mb and 256 mb

Stacked Cells occur when individual batteries are stacked together, to achieve a higher voltage and or Power. They can store up to 1 GB of data.

Planar Capacitor, unlike stacked cells and trench capacitors, can only store data of not more than 1 mb. Planar Capacitor happens to be the smallest out of the three.

From the above explanation, it is obvious that Stacked Cells is the answer.
