Question 1 1 out of 1 points Two small metallic spheres of mass 0.2g are suspended as pendulums by light strings of length L. The spheres are given the same electric charge so they repel each other. They come to equilibrium when each string is at an angle of 5 degrees from vertical. There are three forces: tension, weight, and electric force. Find the electric force required for equilibrium. Do this like a Physics 251 problem. Selected Answer: 000172 Question...
please answer d & e with full explanations, thanks!
1. This problem investigates the use of the Hall effect to study blood flow. When a current / travels along a conducting plate of width w, which lies perpendicular to a magnetic field B, a potential difference V develops across the plate as shown in the figure below. + + + + + + a. Show the direction of the electric field on the diagram. (Either copy the diagram from this...
3. Fill the blanks and the Proof - J.J. Thomson's experiment to fine the charge-to-mass ratio of the tt) (25 points) electron (i.e. e/m; The first is the experiment of Joseph John Thomson, who first demonstrated that atoms are actually composed of aggregates of charged particles. Prior to his work, it was believed that atoms were the fundamental building blocks of matter. The first evidence contrary to this notion came when people began studying the properties of atoms in large...
I need help with all these please! Thanks!
1. Two identical metal balls are suspended by insulating threads. Both balls have the same net charge. In this problem, do not assume the balls are point charges Ball 2 a. Draw a separate free-body diagram for each ball. Label the forces to indicate: . the object exerting the force, the object on which the force is exerted, • the type of force (gravitational, normal etc.), and • whether the force is...
please answer all I beg you ASAP! and please try solving most of
them thabk you so much
Question 23 (1 point) At an instant a traffic light turns green, a truck starts with a constant acceleration of 1.8 m/s2. At the same moment a taxi travelling with a constant speed of 8.5 m/s overtakes and passes the truck. Which two equations properly describe the position of the truck and the taxi? a) dtruck = 8.5at dtaxi = 8.5at b)...
please help and answer all ASAP please thank you so much
Question 49 (1 point) When light travelling in glass enters glass with a higher index of refraction, the wave will be: a) partially transmitted with a change in phase b) transmitted forming a standing wave pattern in air c) reflected so as to form a node at the junction d) totally reflected at the junction e) partially reflected without a change in phase Question 38 (1 point) The charge,...
