The Earth is 1.5x10 11 m from the sun and has period of 365 days. Determine the magnitude of its centripetal acceleration.
A 7 meter long run of 16 gauge wire which consists of a 4 meter long piece of aluminum wire piggy-backed to a 3 meter long piece of copper wire. Calculate the current in the aluminum segment
A boy whirls a stone in a horizontal circle of radius 1.2 m and at height 1.5 m above level ground. What is the magnitude of the centripetal acceleration of the stone
A mass spectrometer has an adjustable magnetic field. When themagnetic field is 7.000e-2 T, a singly ionizedhydrogen atom (a proton) will strike the detector at a particularlocation. Suppose a triply-ionized carbon 12 atom, whose mass is bydefinit..
a slit 0.30 mm wide is illuminated by light of wavelength 426 nm. a diffraction pattern is seen on a screen 2.8 m from
the rubber worn from tires mostly enters the atmosphere as particulate pollution. estimate how much rubber in kg is put
When the reflected wave is superimposed on the original wave, it is found that the sum produces a beat frequency fbeat= 0.058Hz. Find the speed of the car. You may assume the speed of sound in air to be 340-ms-1.
A mass-spring system oscillates with an amplitude of 4.40 cm. If the spring constant is 237 N/m and the mass is 411 g, Determine the maximum speed of the object
A harvest mouse can detect sounds as quiet as -10 . Suppose you are sitting in a field on a very quiet day while a harvest mouse sits nearby at the entrance to its nest. A very gentle breeze causes a leaf 1.8 from your head to rustle, generating a..
A large circular capacitor with a radius of 5 m is separated by 3 mm of air. Suppose 9 V is placed across the capacitor. What is the charge magnitude that builds up on the two plates
AN ELECTRIC MOTOR ACCELERATES THE 6-in DIAMETER GRINDING WHEEL AT A RATE 0F 150 rad/s2 FROM REST UNTIL IT REACHES ITS OPERATING SPEED OF 3600 rpm. DETERMINE: The time in seconds required for the wheel to reach 3600rpm
A block has an initial speed V(o) > 0 on a linear trajectory on the surface with friction coefficient u and air resistance (F = cv^2). Derive an equation that will represent the velocity (V) as a function of the position of the block (x). So V(x).
An electron has a speed of 0.750c. Find the speed of a proton that has the same kinetic energy as the electron
