C. A combined circuit
That’s the answer
Answer:
Mid-Ocean Ridges
Explanation:
The mid-ocean ridges is an underwater mountain system formed by diverging oceanic plates.
- This mid - ocean ridge is one of the prominent land mass on the earth surface.
- At a diverging center, two tectonic plates are pulling apart from one another.
- This creates a space which allows for magma to rise up.
- The magma then crystallize to form an extensive ridge network known as the mid - oceanic ridge.
- The continental expression of the ridge can only be found in Iceland
Remember opposites attract and same charges repel each other.
Object A= negatively charged.
Object A and B attract so B must be positively charged.
Object B and C repel so because B is positively charged C must also be positively charged.
Object C and D attract and because C is positively charged, D must be negatively charged.
Answer: Molecules of H202, H20 and 02 are still forming. ( A P E X )
Explanation: I know this is late but for anyone looking at this later
55 J
Explanation:
Kinetic energy is given as: 0.5MV^2 where M is the mass and V is the speed of rotation. Since the masses are point masses, we calculate the point mass for each mass.
M1 = 30*0.2^2 = 1.2kgm^2
M2 = 20*0.4^2 = 3.2kgm^2
V = 5 rad/s
Calculating using the formula above, we obtain :
0.5(1.2+3.2)5^2 =0.5*4.4*25 = 55 J
