Answer:
Explanation:
Density = Mass / Volume = 850 / 40*10*5 = 0.425 g /cm^3
The answer is Maria or Lunar mare because they are both made of basalt. Hope this helps.
Answer:
24.531 m
Explanation:
t = Time taken = 1.7 s
u = Initial velocity = 6.1 m/s
v = Final velocity
s = Displacement
g = Acceleration due to gravity = 9.81 m/s² = a
Equation of motion

The initial height of the rock above the ground is 24.531 m
Total resistance=R1+ R2= 6Ω
Voltage=12v
Current =

Current= 2A
In a series circuit, equal current passes through every resistance.
Answer is option A
