Answer:
2 g/cm³
Explanation:
m = Mass of object
v = Volume
ρ = Density
When ρ = 2 g/cm³ , v = 5 cm³
All the objects have same mass, which is 10 grams
When v = 5 cm³
Density of third object is 2 g/cm³
Answer:
No, there are always protons, neutrons, and electrons. When an object is neutral, it means the positive and negative charges sum to zero (are equal and opposite). NO, if an object has no net charge it simply means that the amount of positive and negative charges (protons and neutrons) are the same.

Answer:
Energy
A wave is a disturbance that carries energy from one place to another through matter and space.
Explanation:
A wave can be defined as a form of disturbance that carries energy from one place to another through matter and space.
The energy of wave depends on the frequency of the wave and the wavelength (lambda) of that particular wave.
Mathematically,
V = f × lambda
1 watt = 1 joule/sec
1800 watts = 1800 joules/sec
(1800 J/sec) x (20 min) x (60 sec/min)
= (1800 x 20 x 60) joules = 2,160,000 joules .
( 2.16 megajoules )
Answer:
You will cover a distance of 1569.06 metres. Or you could round down to 1,569m.
Explanation:
20.7*75.8=1563.06
