The answer would be c because a surface wave travels between two different materials, like air and water.
Answer:
has a radius of 2439 km (1524 mi), and the metallic iron-nickel core is believed to make up about 75% of this distance. Measurements of the planet's magnetic field made by Mariner 10 as it flew by the planet indicates that this core is likely to be hot and fluid.
Answer: P = 40 W
Explanation: Power is defined as the amount of work per unit time or expressed in the formula of P = W /t
Work is the product of force and distance so W = Fd.
So the working equation will be:
P = Fd / t
= 20 N ( 2.0 m) / 1 s
= 40 W
Is the amount of power exerted.
Answer: After fusing helium in its core to carbon, the Sun will begin to collapse again, evolving into a compact white dwarf star after ejecting its outer atmosphere as a planetary nebula. The predicted final mass is 54.1% of the present value, most likely consisting primarily of carbon and oxygen.
