Suppose that you are carrying a suitcase that contains a gyroscope whose large angular velocity is directed horizontally forward. As you attempt to turn the suitcase to the left, explain what happens to the suitcase? And why?
An ultralight plane and pilot have a total mass of 168 kg, what is the net force acting on the plane and pilot
At a distance r1 from a point charge, magnitude of the electric field created by the charge is 296 N/C. At a distance r2 from the charge, the field has a magnitude of 168 N/C. Find the ratior2/r1.
A ball is dropped from height of 20 m above the surface of water in a lake. The refractive index of water is 4 / 3. A fish inside the lake, in the line of fall of the ball, is looking at the ball. At an instant, when the ball is 12.8 m above the wate..
An electron that is moving through a uniform magnetic field has a velocity v = (30 km/s)i + 18 km/s)j when it experiences a force F = (-4.000×10-15 N)i + (6.667×10-15 N)j due to the magnetic field. If Bx = 0, calculate the magnitude of the magnetic f..
A man enters a tall tower, needing to know its height. If this pendulum is taken to the Moon, where the free-fallacceleration is 1.67 m/s2, what is the period there
Two flat surfaces are exposed to a uniform, horizontalmagnetic field of magnitude 0.49 T. When viewed edge-on, the firstsurface is tilted at an angle of 11° from the horizontal, and anet magnetic flux of 8.00 10-3 Wb passes through it. The same ne..
A 23 meter long log of irregular cross section is lying horizontally, supported by a wall at one end and a cable attached 4.0 meter from the other end. Find where is the log's center of gravity
house painter stands 3 m above the ground on a 5.2-m-long ladder that leans against the wall at a point 4.7 m above the ground. find the force of friction that the driveway exerts on the bottom of the ladder
The syringe must be heated to high temperatures to sterilize it. When the syringe is at its maximum temperature, what is the rms speed of the oxygen molecules
A 700 N man stands in the middle of a frozen pond of radius 5.0 m. He is unable to get to the other side because of a lack of friction between his shoes and the ice. To overcome this difficulty, he throws his 1.2 kg physics textbook horizontally t..
Caluculate the radius of the path of this electron if itsvelocity is erpendicular to the magnetic field
A tungsten target is struck by electrons that have been accelerated from rest through a 67.8-kV potential difference. Find the shortest wavelength of the radiation emitted
