Physics

SCORPION-xisa [38]3 years ago

Answer: Option (4) is the correct answer.

Explanation:

Number of waves that pass through a given point in a per unit time is defined as frequency.

Therefore, when each crest or trough of a wave are closer then it means frequency of the wave is greatest. Whereas when each crest or trough of a wave are far away from another crest or trough of the same wave then it means frequency of wave is the smallest.

Thus, we can conclude that out of the given waves, option four displays a wave with greatest frequency.

How much kinetic energy does a proton gain if it is accelerated, with no friction, through a potential difference of 1.00 V? The

ra1l [238]

Answer:

If energy is conserved, then the sum of the potential energy and the kinetic energy is a constant.

Assuming the proton starts from rest, so it's kineitc energy is zero, but it has a potential energy, PE equal to:

PE = qV

where q =1.6 x 10^-19 C

and V = 1.00 V

Assuming the proton no longer experiences the potential energy and it is all converted to kinetic energy then:

PE* = 0,

KE* = 1/(2mv^2)

Now since

PE + KE = Total energy =PE* + KE*

Therefore,

qV + 0 = 0 + 1/2mv^2

KE = qV = 1.6 10^-19 J

1.15) What distance will 650 joules of work move a box weighing 50 newtons?

son4ous [18]

Answer:

The answer is 13 however make sure if they ask for a certain measurement like meter answer it by saying 13 meters.

Explanation:

This basically turns into basic algebra if you know the formula for work. The formula for work is W=F*d

Here are the variables that you know 650J=50N*d so you need d.

All you do is divide 650J by 50N and you get a total of 13 (meters since I don't know what they want you to put it in).
