Answer:
b. amplitude
Explanation:
An electromagnetic waveconsists of electrical oscillations and magnetic fields. The frequency of the wave is directly proportional to its energy and its speed and inversely proportional to its wavelength. Therefore, with the only magnitude with which it has no relation is with its amplitude.
Power = (voltage) x (current)
100w = 220v x current
Current = 100w / 220v = <u>0.455 Ampere</u> (rounded)
Answer:
4. A 10-kilogram sled at rest
Explanation:
The object with most inertia is a 10-kilogram sled at rest.
Inertia is the tendency of a body to remain at rest or continue with uniform motion.
Now, this is better highlighted by Newton's first law of motion which states that "an object will remain in a state of rest or of uniform motion unless it is acted upon by an external force".
- The more the mass of a body, the greater its inertia
- So, the choice with the most mass will have the highest inertia and will be the most reluctant to change position.
