(a) Space vehicles traveling through Earth's radiation belts can intercept a significant number of electrons. The resulting charge buildup can damage electronic components and disrupt operations. Suppose a spherical metallic satellite 1.28 m in diameter accumulates 3.70?C of charge in one orbital revolution. Find the resulting surface charge density.
(b) Calculate the magnitude of the resulting electric field just outside the surface of the satellite due to the surface charge.
The quartz crystal in a digital watch has a frequency of 32.8 kHz. What is its period of oscillation?
Concept to find certain type of electronic devices & circuits.
A 2.30 N force pushes it to the left, and a 0.800 N force pushes it to the right. (a) Taking right to be positive, what is the net force acting on it? (b) What is its acceleration?
A motorcycle has a constant speed of 21.0 m/s as it passes over the top of a hill whose radius of curvature is 132 m. The mass of the motorcycle and driver is 343 kg. Determine the magnitude of the normal force that acts on the cycle.
Two people stand 3 m away from a large plane mirror and spaced 3.8 m apart in a dark room. At what angle of incidence should one of them shine a flashlight on mirror so that the reflected beam directly strikes the other person.
A copper laboratory tank has a diameter of 0.48 m at 20degree celcius. what would be the new diameter if the tank is filled with 80degree celcius alcohol.
Two wheels have the same mass and radius of 4.5 kg and 0.39 m, respectively. One has (a) the shape of a hoop and the other (b) the shape of a solid disk. The wheels start from rest and have a constant angular acceleration with respect to a rotatio..
A positive point charge Q is on the y axis at y = D; a negative point charge -2Q is at the point x = D, y = D. Find the potential for points on the x axis
suppose that both cars start at the same point, how much sooner does the faster car arrive at a destination 35 km away.
A force acts on a block weighing 45N. The block is initially at rest on a plane inclined at angle θ = 18.0° to the horizontal. The positive direction of x axis is up the plane.
A 55kg pole vaulter running at 10m/s vaults over the bar. If the vaulter's horizontal component of velocity over the bar is 1.10m/s and air resistance is disregarded, how high was jump.
