Mama L [17]3 years ago
7 0

Answer:

\large \boxed{\mathrm{C. \  \  \frac{500}{7 \times 15  \times 8} \ g/cm^3 }}

Explanation:

\displaystyle \sf Density = \frac{mass}{volume}

\displaystyle \rho = \frac{m}{V}

\sf mass=500 \ g

\sf volume \ of \ a \ cuboid=width  \times length  \times height=( 7 \times 15 \times 8) \ cm^3

\displaystyle \rho = \frac{500}{7 \times 15  \times 8}

How many protons does Aluminum have?
Lorico [155]

Answer:

The atomic number of Aluminum is "13"!

Explanation:

The 27 means the atomic mass is 27 . The number of protons plus the number of neutrons is 27. That means the number of neutrons is 27–13=14. Number of neutrons depends on the isotopic form of aluminium.

A series circuit that is connected to a 50 V, 60 Hz source is made up of 25 ohm resistor, capacite wieh X= 18 ohms, and inductor
Allisa [31]

Answer:

the impedance of the circuit is 25.7 ohms.

Explanation:

It is given that,

Voltage, V = 50 volts

Frequency, f = 60 Hz

Resistance, R = 25 ohms

Capacitive resistance, X_C=18\ ohms

Inductive resistance, X_L=24\ ohms

We need to find the impedance of the circuit. It is given by :

Z=\sqrt{R^2+(X_L-X_C)^2}

Z=\sqrt{25^2+(24-18)^2}

Z = 25.7 ohms

So, the impedance of the circuit is 25.7 ohms. Hence, this is the required solution.
