What is a gyroscope? Discuess the role of angular momentum in operation of a gyrosope. Provide examples of pratical applications of gyryscopes.
You push on the chair with a force of = 37.0 directed at an angle of 43.0 below the horizontal and the chair slides along the floor. Using Newton's laws, compute the magnitude of the normal force that the floor exerts on the chair.
A metal sphere with radius r_a is supported on an insulating stand at the center of a hollow, metal spherical shell with radius r_b. There is charge + q on the inner sphere and charge - q on the outer spherical shell. Take potential V to be zero w..
Explain how many atoms strike the umbrella each second? Assume that the wind blows horizontally so that the gravity can be neglected.
The largest apple pie ever made was rectangular in shape and had an area of 7m× 12m. Consider a parallel-plate capacitor with this area. Imagine that the capacitor is filled with air and the distance between the plates is 1mm. a.
At each of the designated points, rotate the given vector to indicate the direction of the force exerted by the water on either the inside of fishbowl (for points A and B) or the outside of the goldfish (for points C, D, and E).
What is the least thickness of a soap bubble film (n = 1.38) on which light of wave length 610nm shines, assuming one observes constructive interference of the reflected light.
When the Sun is directly overhead, a hawk dives toward the ground with a constant velocity of 5.30 m/s at 68.5° below the horizontal
Assume that the volume of the empty spaces between the candes is negligible. If the height of the candes in the container increases at the rate of 0.270 cm/s, at what rate (kilograms per minute) does the mass of the candies in the container increa..
Consider an angular motion. If the displacement is given as 250teθ, and the radius r is constant, derive the expressions for the angular velocity θ=ω, angular accelerationα, linear displacements, linear velocitytv, normal accelerationna, and tange..
Suppose the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you found in part A. What should be maximum speed of the car so it can round the curve safely?
Why is it better for some purposes to use a medium size telescope on a mountain instead of a telescope in space?
What is the minimum coefficient of friction between tires and road.
