Part A What is the speed of light in ethyl alcohol (n = 1.36)?
Part B What is the speed of light in lucite (n = 1.50)?
Part C What is the speed of light in crown glass (n = 1.52)?
A pulsed proton beam is fireat a target each last 45.0ns and there 3.00 X 10^9 protons in each pulse, What is the average pressure on the beam spot during the pulse if the protons are absorbed by the target
It takes a minimum distance of 48.96 m to stop a car moving at 12.0 m/s by applying the brakes (without locking the wheels). Assume that the same frictional forces apply and find the minimum stopping distance when the car is moving at 26.0 m/s.
At one instant a bicyclist is 25m due east of a park's flagpole, going due south with a speed of 8 m/s. Then, 11 s later, the cyclist is 65m due north of flagpole, going due east with a speed of 10 m/s.
Analyse the instantaneous velocity of the car
Suppose the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you found in part A. Illustrate what should be the maximum speed of the car so it can round the curve safely?
The density of the sea water is 1025 kg/m3. The density of ice is 917 kg/m3. Explain how high does the top of the ice block float above the water level?
A standing wave in a pipe with both ends open has a frequency of 680 Hz. The next higher harmonic has a frequency of 1020 Hz, How long is the pipe
What are (a) x component and (b) y component of a vector in the xy plane if its direction is 329° counter clockwise from the positive direction of the x axis and its magnitude is 9.0 m.
If the curve were not banked, elucidate the minimum coefficient of friction between tires and road that would keep traffic from skidding out of the turn when traveling at 97 km/h?
The centripetal and tangential accelerations are equal
An object of mass 45.0 g is initially placed in boiling water so that it is at 111° C. Then the object is dropped into a calorimeter, Find the specific heat of the object
