Calculate the wavelength associated with electrons moving with p.d of 1500v
Artist 52 [7]

Answer:

3.16X10∧-11 m

Explanation:

1/2 mv2 = qV (KE = Electric potential energy)

velocity = √2qV/m = √( 2X 1.6X10∧-19 X 1500/9.11X10∧-31)

2.3X10∧7m/s

now use De Broglie equation

λ = h/mv

= 6.62X10∧-34/( 9.11X10∧-31 X 2.3X10∧7)

3.16 X 10∧-11 m

or

use the above equations and substitute to get the final eqiation

λ = h/√(2mqV) = 3.16X 10∧-11 m

Help for 50 points thank you
Korolek [52]

Answer:

Explanation:

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. ... Therefore, the oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy. This energy propagates in the same direction as the wave.

Which object moves in simple harmonic motion?\
Rina8888 [55]
<h2>Answer:Stretched rubber band with an mass</h2>

Explanation:

Simple harmonic motion requires a restoring force.

Simple harmonic motion should be periodic.

Option A:

When a rubber band is stretched,the internal forces of the rubber band pulls the band inside.So,internal forces are the restoring forces in a rubber band.

The motion is periodic as well since the the rubber band makes to an fro motion expanding ans contracting.

So,this performs SHM.

Option B:

There is no restoring force and no periodicity.

So,this is not SHM.

Option C:

There is no restoring force and no periodicity.

So,this is not SHM.

Option D:

There is periodicity but no restoring force.

So,this is not SHM.

Your laundry basket Please 22 is in your room is 3.0 M above you on the second floor it takes you 6.0 seconds to carry the laund
Rainbow [258]

Power = (work done) / (time to do the work)

Work done = (force to lift the object) x (distance lifted)

In this question, the force is the (weight of the basket)+(your weight).

Work done = (weight of basket+you) x (3 meters)

Time to do the work = 6 seconds.

Power = (weights x 3 meters) / (6 seconds)

<em>Power = (1/2)·(weight of the basket+you, in Newtons) watts</em>
