A muon and an antimuon are moving in opposite directions with velocities of -0.4 c and 0.4 c, respectively. When they collide, they can annihilate each other and turn into two photons. Both muon and antimuon have a mass of 105.66 MeV/c2.A) What is the total energy before the collision?
B) What is the energy of each photon?
C) What is the wavelength of each photon?
An uncharged nonconductive hollow sphere of radius16.0cm surrounds a17.0µC charge located at the origin of a cartesian coordinate system. A drill with a radius of 1.00 mm is aligned along thezaxis, and a hole is drilled in the sphere. Calculate th..
With an average mass of only 30.0 g, the ouse lemur of Madagascar is the smallest primate on the earth. What is the lemur's tangential speed at that point
The potential difference across a cell membrane form outside to inside is initially at -90 mV (when in its resting phase). How many ions move through the membrane
An airplane is flying with a velocity of 95m/s at an angle of 19.0^circ above the horizontal. When the plane is a distance 124m straight above a dog that is standing on level ground, suitcase drops out of luggage compartment.
A glass sheet 1.10 ?m thick is suspended in air. Calculate the minimum value of the index of refraction of the glass sheet that produces this effect
while the other terminal of the ammeter is connected to the other wire, ammeter shows that the current through the wire is 1 A. You then disconnect everything and travel to the other end of the telephone line, where you repeat the process and find ..

An athlete crosses a 28 m-wide river by swimming perpendicular to the water current at a speed of 0.8 m/s relative to the water, How fast is the water in the river flowing with respect to the ground in m/s
a parallel-plate capacitor with plate are A and separation x has charges +Q and -Q on its plates. The capacitor is disconnected from the source of charge, what is the total energy stored in the capacitor
A 1.5kg weight hangs from a 8.0kg, solid wheel with a 20 cm circumfrence by a thin string wrapped several times around the circumfrence. How fast (in radians/second) is the wheel turning just before the weight hits the floor
you're designing a prosthetic ankle that includes a miniature electric motor containing a 150-turn circular coil 15 mm in diameter. The motor needs to develop a maximum torque of 3.1 mN-m. what current do you need in your motors coil
A low-voltage device like an electric bell obtains its electricity from a 120 V source, but requires only 4–8 V. Thus,it requires a small transformer. This often takes the form of an autotransformer, which has only one winding around a single core..
