A force of 40.0 N accelerates a 5.0-kg block at 6.0m/s^2 along a horizontal surface.

a. how large is the frictional force?
b. what is the coefficient of friction?

Please help me with these questions.
I'm having trouble understanding them.

I have posted this question before, and have seen many different, and varying answers. There seems to be a problem with this question.

My physics class has a large focus on learning from the textbook, yet I am not able to learn effectively this way. What is the best way to learn from the textbook? Are there any other books/materials that could assist me?

Is it possible that a future time travel experiment gone wrong could alter our space-time continium to the point that the Earth could get trapped in a never-ending time loop?

If we were, is there any possible way that we could break it?

Ok, so the question goes 'A photon has a frequency (v) of 9.73x10^14Hz. Use the relationships E=hv and c= (gamma sign - can't do it on here!) v to calculate the wavelength of the photon and the energy contained by 1mol of such photons. To what region of the electromagnetic spectrum does this photon belong?
c=2.9979x10^8 m s-1 h=6.626x10^34 J s-1 Na = 6.022x10^23 mol-1


Please please don't just tell me the answer because I already have that, I need to know How to do it. Also if you know any website that can explain all this stuff that would be a Great answer too! Thanks:)

I know it's possible to slow light down in a medium to a point where you can see it moving. However, the speed of light remaind 3x108... what's really going on?

Carefully balance an embroidery hoop vertically on the mouth of a narrow-mouth bottle. Stack the nuts on the top of the hoop. The idea is to get as many nuts as possible into the bottle by touching the hoop with only one hand..

my friends and i did that and LUCKILY we beat the class and got 10 in the bottle w/out dropping one...

I have to write a CONCLUSION and I'M CLUELESS.. How does this deal with inertia.. i got how my 6 other ones did but not this..



MUCHOS GRACIAS.. GOD BLESS :)

Ignoring attenuation by the Earth's atmosphere, how far out along the beam will the beam be travelling tangentially at the speed of light? Beyond this distance along the beam, will it be travelling tangentially faster than the speed of light? Remember, I am not refering to the speed radially, along the beam, but rather tangentially as it rotates. Also, please ignore the speed of rotation of the Earth, I am only interested in the rotation of the beam.

Can someone explain this in terms of inertia... finally, i think i'm starting to get what inertia is but how does this relate to it?

2. A sailboat with a mass of 2.0 * 10^3 kg experiences a tidal force of 3.0 * 10^3N directed to the east and a wind force against its sails with a magnitude of 6.0 *10^3N directed toward the northewest (45 degrees N of W). What is the magnitude of the resultant acceleration of the boat? (My answer was 4.7 m/s^2)

Has anyone ever witnessed a photon, or seen a photon cause things that only an inertial particle would cause? I read that photons are massless, so how can they have inertia? If photons are massless, why is it that they can't travel through all mediums? Why is it that the scientists seem to think there are an endless supply of photons.

I understand that sound won't travel through a vacuum. Therefore, light shouldn't be able to travel in a vacuum if it is simply a wave, right? I don't believe so. I believe that solid substances (in terms of particles like protons and electrons) are made of intensely grouped bundles of energy. A vacuum, in turn, would be a level, dispersed, sort of flat region of indifferent energy. Stephen Hawkings suggested this with the string theory.

Where is the proof that light is made of photons???

I understand the photoelectric effect, but it's possible that the particular frequency of the light actually affects the metal (like a resonant frequency) .
