Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions (Au2+), each with a mass of 3.27 × 10-25 kg. The ions are accelerated from rest through a potential difference of 2.30 kV. Then, a 0.470-T magnetic field causes the ions to follow a circular path. Determine the radius of the path.
Find the position of an object in front of a screen to obtain an image of size twice larger than its original size on the screen.
Two cesium-133 atomic clocks differ by one second in 6000 years. Assume one of the clocks gains one second in six thousand years, approximately what is the change in the number of oscillations of the light each second?
find out the angular speed after the grindstone has made.
The Mariana trench is located in the Pacific Ocean at a depth of about 11 000 m below the surface of the water. For comparison, determine the weight of a jetliner whose mass is 8.19 × 105 kg
A loudspeaker of mass 19.0 kg is suspended a distance of h = 2.00m below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l= 3.50m. Illustrate what is the tension T in each of the cables?
Barometric pressure in the eye of a hurricane is 0.91atm (27.2 in of mercury). How does the level of the ocean surface under the eye compare with the level under the distant fair-weather region where the pressure is 1.0atm.
Consider a bar (L=3.00m) is sliding to the right on 2 rails with a velocity (0.75 m/s) towards a resistor (20 ohms), calculate the "Magnetic Braking force"
During a panic stop, a car decelerates at 7.00 m/s^2. What distance does the car travel in this time
