The electric field in an xy plane produced by a positively charged particle is 4.94(6.9i + 4.4j)N/C at the point (5.9, 5.8) cm and 131i N/C at point (2.8, 0)cm. What are (in cm) the
(a) x and
(b) y coordinates of the particle?
(c) What is the charge (in Coulombs) of the particle?
How many electrons would have to be added to one of these spheres to make it electrically neutral?
Immediately before the collision, the linebacker is slipping with a velocity of 8.6 m/s north and the halfback is sliding with a velocity of 7.4 m/s east. Illustrate what is the magnitude of the velocity at which the two players move together imm..
However, the current begins to decrease as the resistive element warms up. When the toaster reaches its final operating temperature, the current has dropped to 1.53 A.
Using and Atwood machine with masses m1 and m2, at first with m1 a distance 2h above m2, what is the speed of either mass they pass each other? Make use of energy to solve (hint they cross halfway between the starting positions of the two masses).
Assume that plane continues to fly with the similar velocity
The battery has internal resistance of 0.100 Ω, and the rod and rails have negligible resistance. A 2.02 T magnetic field is directed perpendicular to the plane of the circuit. Find the magnetic force on the rod. F= 38.78 N. Find out the rod's spe..
assume the current in the coaxial cable, see the figure , is not uniformly distributed, but instead the current density varies linearly with distance from the center: for the inner conductor and for the outer conductor. Each conductor still carrie..
Find out line linking the two point charges
After falling from rest from a height of 28 m, a 0.46 kg ball rebounds upward, reaching a height of 18 m. If the contact between ball and ground lasted 1.7 ms, illustrate what average force was exerted on the ball?
rate at which mechanical energy is transferred to the turbine blades, assuming 60 percent efficiency.
A proton is released from rest in a uniform electric field of magnitude 421 N/C. (a) Find the electric force on the proton. magnitude N direction (b) Find the acceleration of the proton. magnitude m/s2 direction (c) Find the distance it travels in..
How many revolutions does the ball make during its fall. Now assume that the ramp is frictionless, so that the ball slides instead of rolling. Through what horizontal distance d does the ball move before landing in this case.
