Monochromatic light falls on two very narrow slits0.042mm apart. Successive fringes on a screen6.50m away are 8.4cm apart near the center of the pattern.
A. Determine the wavelength of the light.
B. Determine the frequency of the light.
If the string is 9.5 m long, has a mass of 45 g and is pulled taut with the tension of 8.0 N, how much time does it take for a wave to travel from one end of the string to the other.
What stage of the scientific method would someone be at if they make a prediction that drinking alcohol will make people more violent throughout a sporting event.
A 2.20 kg frictionless block is attached to an ideal spring with forces constant 314N/m. At first the block has velocity -3.60 m/s and displacement 0.300-m.
In response to a stimulus, membrane can become permeable to Na ions. As Na ions rush into the cell, the interior of the cell reaches an electric potential of about 40 rm mV.
One long wire lies along an x axis and carries a current of 42 A in the positive x direction, What is the magnitude of the resulting magnetic field at the point (0, 2.0 m, 0)
What is the net charge inside the sphere.
Two boxes A and B are connected to each end of a light vertical rope. A constant upward force 80.0 is applied to box. Starting from rest, box descends 10.4 in 3.40. The tension in the rope connecting the two boxes is 37.0
Dizziness. Our balance is maintained, at least in part, by the endolymph fluid in the inner ear. Spinning displaces this fluid, causing dizziness, What is the radical acceleration (in m/s^2) of the endolymph fluid
A 2700 kg truck traveling north at 42 km/h turns east and accelerates to 53 km/h. What is the change in the truck's kinetic energy
A 225-m length of wire stretches between two towers and carries a 180-A current. Determine the magnitude of the force on the wire due to the Earth's magnetic field
Let us use the uncertainty principle to (very roughly) estimate the size of a hydro- gen atom. Picture the hydrogen atom as an electron orbiting a proton at close to the speed of light.
A car of mass m moving at a speed v1 collides and couples with the back of a truck of mass 3m moving initially in the same direction, What is the change in kinetic energy of the car-truck system in the collision
