What Is The Difference Between An Atom In The Ground State And An Atom In An Excited State? (2023)

Physics College

I will answer both versions assuming what you want to know is the distance it travels up from and over the ground. and how long until it reaches space. 540 meters per second up and over. to reach space which is 100km above sea level, it would take about 5400 minutes

It's not so much a "contradiction" as an approximation. Newton's law of gravitation is an inverse square law whose range is large. It keeps people on the ground, and it keeps satellites in orbit and that's some thousands of km. The force on someone on the ground - their weight - is probably a lot larger than the centripetal force keeping a satellite in orbit (though I've not actually done a calculation to totally verify this). The distance a falling body - a coin, say - travels is very small, and over such a small distance gravity is assumed/approximated to be constant.

Some guidance notes which may help.To calculate the current flow, Ohm's law can be used. This can be written as current=voltage/resistance, or I=V/R. V is 1.5V.R for the copper wire quoted would be calculated as R = resistivity x length/cross sectional area. The area would be calculated from the formula area = pi x diameter squared/4So, R=resistivity x length divided by (pi x diameter squared/4)Until is the resistivity of copper is known, that's about as far as can be gone.Any further questions, please ask.

C.
identify more prescriptive than descriptive premises.

Newtons third law of motion

The charge on the electron is 1.6x10^-19C. So, 10^24 of them will be a charge of 1.6x10^5C,F = q1xq2/[(4pi epsilon nought)r^2]

This question is related to inertia: To peel off a piece of paper from a roll, in what way is it better to do it?

a) Slowly pulling the roll

b) Slowly pulling the piece of paper

c) Pulling suddenly the roll

d)Pulling suddenly the piece of paper

The way I do it is suddenly, in the same sort of way that magicians try to pull a table cloth off a table when there's things on the table cloth.The sudden approach acts as an impulse of force and starts to accelerate the roll. But, the piece (assuming it has perforations) is off the roll before the roll can move, due to inertia. Then the roll will acclerate, move, slow down and stop. However, in accelerating, the roll will unravel. The bigger the impulse the more it will unravel.+++++++++++++++++++++++++++++++++++++++If on the other hand, the piece of paper is held firmly, and the roll is pulled, then the impulse is presumably given to the paper and the hand whose inertia is a lot more than that of the roll. So, I think I'd actually go for choice c)+++++++++++++++++++++++++++++++++++++This assumes that the roll is free to rotate.I think that a similar idea is behind the design and use of a "ballistic galvanometer". The charge is passed through the galvanometer quickly, as a current pulse. Then the needle starts to deflect, and the deflection is arranged to depend on the total charge that has passed through in the time of the current pulse.

True...A movingobjectwith a zeroresultant forcekeeps moving at the same speed and in the same direction. If theresultant forceacting on anobjectis not zero, a stationaryobjectbegins toacceleratein the same direction as theforce. A movingobjectspeeds up, slows down or changes direction

I have tried to answer this inverse square Coulomb's law question more fully, but have been blocked from doing so. I do not know why.

The city of Denver is located approximately one mile (1.61 km) above sea level. Assume you are standing on a beach in Los Angeles, California, at sea level; estimate the angle of the resultant vector with respect to the horizontal axis between your location in California and Denver. a) between 1 degrees and 2 degrees

b) between 0.5 degrees and 0.9 degrees

c) between 0.11 degrees and 0.45 degrees

d) between 0.06 degrees and 0.10 degrees

e) less than 0.05 degrees
the power-point says the answer is D, but how do i solve it?
thank you in advance

As a thought, I'd say that you need to know how far D and LA are apart in km. If the q doesn't give you that, then it's presumably down to a map, or some other such way of working out their separation distance. Once you've got that distance, and assume that it's a horizontal distance, then you' ve got a right angled triangle. in "normal" trigonometry, it would tan angle = opposite/adjacent. But for small angles, tan angle is approx equal to the angle, I think, as with the sine of a small angle.

They will fall together and land together, since there is no air resistance to slow the feather down. Classic experiment, I believe it was tried on the moon years ago.

Since a straight line on a distance time graph implies uniform speed, and falling is an acceleration - a non uniform speed - I woul not expect a straight line.I would expect to get a parabola.This is based on the kinematic equation s=ut+(1/2)at^2.If something is dropped from rest, u = 0; so s = (1/2)at^2Which is, I think, the equation of a parabola.

The ball's horizontal component of velocity (ie it's horizontal speed) is 20 cos 40degrees. Without knowing the distance of the ball to the wall it's difficult to go further ...
