Ask any outdoor photographer.... Polarizing filters are useful for pulling up colors or making the cloud/sky brightness balance shift.
This is also how bees navigate.
The light from the sky is polariz
I was a physics major at USF with abysmal grades some time ago and I sort of panicked and got a degree from Thomas Edison State College (not prestigious, but I figured any B.A. is better than none). I
A stalled car is being pushed up a hill by three people, and it is moving at a constant speed. The net force on the car is:
a. zero.
b. in the opposite direction of the cars motion.
c. in the same di
Im not understanding this problem in the book and why the answer is what it is.
Concider an 8-Newton object that is 2 meters above the floor.
A) What is tis PE with reference to the floor.(16J)
B) Ho
How can i figure out the velocity of an object with knowing only the time which is 6.0s and the distance which is 50m???-Velocity is the motion of an object in a direction right. Therefore its equatio
can anyone help me please... i cant do it-v = u - gt = 32.1 - 9.81 * 4 = -7.1 m/s-Now to answer this question apply equations of motion that is v=u+at.
But u=32.1m/s
v=?
t=4s
g=9.8m/s square
so v=32.1
8. What power is needed to lift a loaded elevator of 1500 kg ten stories (30 m) in 2.0 min?
9. A sled is pulled with a rope which makes a 40.00 angle with the ground. The average tension in the rope
when a weight (500g) is attached to the lower end, it descends 10 cm and comes to rest. the weight is pulled down 20 cm, where it touches the floor. The strings force is proportional to the strings ex
Im probably being very thick-sculled right now and sound like a complete idiot..... So I was hoping someone could help me correct that. I get that you cant know the exact location of a particle, (say
It has only been fairly recently that 1.0-F capacitors have been readily available. A typical 1.0-F capacitor can withstand up to 5.00 V. To get an idea why it isnt easy to make a 1.0-F capacitor, ima
The body in Fig. 10-37 is pivoted at O. Three forces act on it in the directions shown: FA = 8.8 N at point A, 9.8 m from O; FB = 15 N at point B, 2.4 m from O; and FC = 23 N at point C, 3.0 m from O.
How fast would a 6-g fly have to be traveling to slow a 1910-kg car traveling at 59 mph by 9 mph if the fly hit the car in a totally inelastic head-on collision?
Please I am trying to learn, so dont
A relief airplane is delivering a food package to a group of people stranded on a very small island. The island is too small for the plane to land on, and the only way to deliver the package is by dro
A Hookes law spring has a spring constant of 10,000 N/m. How far must the spring be compressed from its equilibrium position to store 100 J of potential energy?-p.e = (1/2)*k*x^2 = 100 J
k = 1e4 N/m

my teacher states that
1: torque = BANI . sin theta
2: torque = BANI . cos phi(where phi is the angle between the coil and the field).
B = magnetic flux density
A= area of coil
N = number of turns
