Density can be calculated using the following rule:
density = mass/volume
plug the given mass and volume into the equation to calculate thr density:
density=57/4.2 = 13.57 g/cm^3

Its Mass divided by Volume. 57/4.2= 13.5g/cm3
if you have to round it, .5 and under :Leave it   .6 and up: round it up 1. 
so in this case, leave it at 13. Hope this helps

What wave phenomena best describes the reason for the dark and light bands that
pickupchik [31]

Answer:

Interference

Explanation:

Interference is the phenomenon in which two waves superimpose to form a wave with smaller, larger or same amplitude.

There are two types of interference namely, constructive interference and destructive interference.

Constructive interference occurs when the waves are in phase and destructive interference occurs when the waves are out of phase.

In a double slit experiment, the two slits acts as sources of light and thus the waves combine to produce interference patterns. When the waves are in phase, that is the angle between them is 0°, they form a constructive interference pattern which gives rise to a light band. When the waves are out of phase, that is the angle between them is 180°, they form a destructive interference pattern which gives rise to a dark band.

Note also that diffraction patterns are also observed for wide slits but can be neglected for smaller slits.

A solar panel is used to recharge a battery. The solar panel produces 0.80 W of electrical power. The panel is 20% efficient. Wh
Vlad [161]

Answer:

Input power, Ip = 4 Watts

Explanation:

Given the following data;

Power output = 0.8 Watts

Efficiency = 20%

To find the power input of the sunlight onto the solar panel;

Mathematically, the efficiency of a machine is given by the formula;

Efficiency = \frac {Out-put \; power}{In-put \; power} * 100

Substituting into the formula, we have;

20 = \frac {0.8}{Ip} * 100

20 = \frac {80}{Ip}

Cross-multiplying, we have;

20Ip = 80

Ip = \frac {80}{20}

Input power, Ip = 4 Watts
