How many leptons are in ⁷₃Li?
shutvik [7]

-- Electrons are leptons.  There are <em>three</em> electrons in each neutral Lithium atom.

The last two parts of the question are absurd.

-- Bonbons are candy, not atomic particles.  A bonbon cannot fit into a Lithium atom.

-- A pentagon is a closed geometric figure that has five sides.  Although you could, in principle, have a pentagon small enough to fit into a Lithium atom, you could never find a piece of paper small enough to draw it on.

Which would be the least effective medium for traveling sound waves? A) gas B) solid C) liquid D) vacuum
Delvig [45]

Answer: The correct answer is vacuum.

Explanation:

Sound wave is a longitudinal wave in which the particles vibrate parallel to the direction of the motion of the wave. Sound wave consists of compression and rarefaction.

It needs a medium to travel. It can travel in solid, liquid and gas. It cannot travel in vacuum.

Denser the medium, more will be the speed of the wave.

Solid is more denser in comparison to liquid.

The speed of the sound in the solid medium is more in comparison to the liquid. The speed of the sound in liquid is more than the speed in the gas.

Therefore, vacuum is least effective medium for traveling sound waves.

a bicyclist initially at rest speeds up steadily during this time interval she averages 3.50 miles per second determine the init
Kobotan [32]

Answer:

Explanation:

Given parameters:

Average speed  = 3.5miles per second

Unknown:

Initial speed  = ?

Average speed  = ?

Final speed in the interval = ?

Solution:

Since the bicyclist started from rest and speeds up steadily, it is correct to assume that her starting or initial speed is 0m/s.

At a state of rest, a body has no speed.

Average speed is the sum total of the speed covered at each time interval. This value is given already to be 3.5miles per second.

Final speed is the speed before the bicycle halts. This speed will be the same as the average speed here which is 3.5miles per second.

Speed is the rate of change of distance with time.
