A balling rolling with initial velocity 5m/s on a table 6m high rolls of the table, find the distance from table to where it lands.-Assuming no air friction:
Time for an object to fall 6 m = t =√2d/g
To hold a block up against a while with your hand pushing at an angle, I know force in y direction plus friction must equal m*g. However if the angle is 0, does that mean to hold up the block, force m
thxx-150 meters bro. Uniform velocity means one direction, and 15 x 10 = 150 m.-150m in the same direction as the velocity.
(A complete answer needs information on the direction, as displacement is a
I was reading today’s paper when I came across this question somebody had asked in the readers’ column: Why does a constantly rotating ceiling fan gather more dust than a stationary table fan? It was,
A rectangular wire loop (dimensions of h = 14.0 cm and w = 6.00 cm) with resistance R = 4.00 Ω is mounted on a door. The Earth’s magnetic field, BE = 5.83 ·10–5 T, is uniform and perpendicular to the
A 345 g chunk of gold (c= .126 J/gK) at 235 C is dropped into 826 g of water at 20.5 C. What will the final temperature of the gold be after the system reaches equilibrium?-Let T = final temperature i
Hi, Im doing a paper on physics and life after death. Im almost finished, I just need some quotes from scientists dealing with the issue. I cant seem to find any quotes on the subject, and I need some
a)What is the change in entropy of 2 g of steam at 100° C as it condenses to water at 100° C?
b) What is the most that you can say about the amount (ΔS) by which the entropy of the rest of the univer
If a 1.6 Vbattery stores 5.4 kJof energy (a reasonable value for an inexpensive C cell), for how many minutes could it sustain a current of 1.4 A ?-First find the power produced by the battery:

Mercury is poured into a U-tube. Left arm has a A1= 10cm^2, and the right arm has a A2=5cm^2. 100g of water is poured into the right arm. The length of the water column is 20cm. Given the density of m
Sure, that would be no problem.

Two lasers are shining on a double slit, with slit separation d. Laser 1 has a wavelength of d/20, whereas laser 2 has a wavelength of d/15. The lasers produce separate interference patterns on a scre
In the circuit figure the emf, epsilon, is 9V, R1 is 2 ohms, and R2 is 6 ohms. What is the magnitude of the current that passes through the wire that is marked A?
To solve this I know you need the ci
