Earth distance to the Sun is about 40 times the Moon's distance from earth.

Explanation:

The Earth's distance from the Sun is about 93 million miles. When it expressed in Km, it is 150 million Km.
The Moon's distance from Earth is 238,855 miles. When it is 40 times then it will approximately equal to 93 million miles.
The Sun's distance from Venus is 67.237 million miles. The Sun's distance from mercury is 35.832 million miles.

An electron is moving at a constant speed of 61 m/s on a circle of radius 3.8 m.

alexira [117]

Charge on electron is 1.6x10^-19 Coulombs.In uniform circular motion v = r omega. omega = v/r. omega= 61/3.8 radians per second - cycle is 2pi radians. (61/3.8)x2pi cycles per second. A charge circulation rate of (61/3.8)x2pix1.6x10^-19 Coulombs/second, or Amps. Which is a pretty small value of a current. Usually there many more electrons moving much faster, I think.

Define average velocity and instantaneous velocity when are they same

Vlada [557]

Answer:

Look to the explanation

Explanation:

Average velocity: is the average rate of change of displacement with

respect to time

Average velocity is a measure for distance traveled in a given time

We can calculate the average velocity by the rule $v=\frac{s}{t}$

where s is the displacement and t is the time

Instantaneous velocity: is the velocity of an object in motion at a

specific point (x , t)

instantaneous velocity is the limit of velocity as the change in time

approaches zero

We can calculate the instantaneous velocity by the rule $v=\frac{ds}{dt}$

Average velocity is equal to the instantaneous velocity when

acceleration is zero
