19 g of helium gas are placed in a cylinder with a movable piston. The gas is compressed very slowly from a state of ( p1 = 5atm; v1 = 32 x 10^-3m^3) to a state of (p2 = 17atm; v2 = 9 x 10^-3m^3 ). The compression is such that the system moves along a straight line in the (p,v) diagram. What is the maximum temperature reached during the compression?
A lens which is 40.0 cm from an object forms an image of the object on a card 20.0 cm away. Determine what is the focal length of the lens? If the height of the image is .75 cm, what is the height of the object?
Charge of -3.30 nC and a charge of -6.25 nC are separated by a distance of 40.0 cm. Find out the position at which a third charge of +7.60 nC can be placed so that the net electrostatic force on it is zero.
A pair of narrow slits, separated by 1.8 mm, is illuminated by a monochromatic light source. Light waves arrive at the two slits in phase. What is the wavelength of the monochromatic light
According to legend, to determine whether the king's crown was made of pure gold, Archimedes measured the crown's volume by find out how much water it displaced. The density of gold is 19.3g/cm^3. If the crown's mass was 6.00 * 10^2g, what volume ..
An archer shoots an arrow with a velocity of 46.0 m/s at an angle of 45.5° with the horizontal. What is the initial speed of the apple
A civil engineer wishes to plan a curved exit ramp for a highway in a way that a car will not have to rely on friction to round the curve without skidding. In the other words, a car moving at the designated speed can negotiate the curve even while th..
