Answer:
Explanation:
Volume of cube=side³
=2*2*2
=8 cm³
Mass of cube=40g
Its density=mass/volume
=5g/cm³
which differs the value given in the text hence it is not gold and u should not bye it...
Instead u should call the police for arresting the person lol...
C
The atomic mass is the sum of the number of neutrons and protons.
Answer:
3.6*10^18s
Explanation:
To find the period of the satellite
We need to apply kephler's third law
Which is
MP² = (4π²/G) d³
d=semi-major axis which is the distance from center of moon = 98km+1740km = 1838km
where M= mass of the moon = 7.3x10^22kg
P=period
G=newtonian gravatational constant= 6.67x10^-11
To find the Period solve for P
P = √[(4π²/G M)xd³]
P=√(4 π²/6.67x10^-22*7.3x10^22kg) x (1.838x10^6m)³]
= 3.6*10^18s
