Answer:

The similarities between the mechanical and the electromagnetic waves are as follows-

  • Both these waves are responsible for carrying energy from one place to another in a particular direction in the form of waves.
  • These waves are characterized by a distinct crest as well as a trough.
  • They are comprised of a definite wavelength (λ), frequency (f) and amplitude (A).
  • Both the type of waves can propagate through a medium.

An asteroid is discovered in a nearly circular orbit around the Sun, with an orbital radius that is 3.83 times Earth's. What is
yKpoI14uk [10]

Answer:

About 7.5 years

Explanation:

The orbital period is proportional to the semimajor axis raised to the power of 3/2.

The orbital period is <em>also</em> inversely proportional to the square root of the sum of the masses of the sun and the asteroid; however, the sun's mass is a constant and the asteroid's mass is negligible in comparison with the sun's mass.

A 60-watt light bulb has a voltage of 120 bolts applied across it and a current of 0.5 amperes flows through the bulb. What is t
Andre45 [30]

Answer:

240 ohms

Explanation:

From Ohms law we deduce that V=IR and making R the subject of the formula then R=V/I where R is resistance, I is current and V is coltage across. Substituting 120 V for V and 0.5 A for A then

R=120/0.5=240 Ohms

Alternatively, resistance is equal to voltage squared divided by watts hence \frac {120^{2}}{60}=240
