## If a battery .charger delivers 5 amp into a battery for 2.2 hours, what charge is transferred in the bane*?

ELECTRIC CHARGE Charge on 1 electron = 1.6 x 10-19 coulomb If a current of 6.0 amp flows for 7.0 seconds, how much charge .has moved? If ~a current of 7.2 amp flows for 25 seconds, how much charge has been transferred? What is the current flowing if 96 coulomb pass a point in a […]

## The two objects shown are both positively charged. Which position could possibly have zero electric field?

Electric Fields 1) The two objects shown are both positively charged. Which position could possibly have zero electric field? – A – B – C – D – They could all have zero electric field   2) What were the two most important forces that Milikan worked with in the oil-drop experiment? – frictional, electrical […]

## Calculate the zero-point vibrational energy for H2 (that is, the vibrational energy the molecule has in the n = 0 ground vibrational level).

ASSIGNMENT The force constant for the internuclear force in a hydrogen molecule 1H22 is kʹ = 576 N/m. A hydrogen atom has mass 1.67 x 10-27 kg. Calculate the zero-point vibrational energy for H2 (that is, the vibrational energy the molecule has in the n = 0 ground vibrational level). How does this energy compare […]

## Devise another way to run this experiment without using a mass on the other end of the balance, but still using a current balance.

Writing Physics lab write up Questions: 1. Derive the final expression from the theory section using torque instead of force. 2. What is the net force on the wires in the balance that run parallel to the solenoid? 3. Devise another way to run this experiment without using a mass on the other end of […]

## What is the angular speed of the system after the piece of putty is dropped on the disk?

Physics M10A, Exam #4, Ch. 9 – Ch. 10 Directions: There 20 multiple choice questions. Each question is 5 points, and the exam is 100 points. The exam is open book, open notes. However, you may not discuss the exam with your classmates. Submit your work for each question in Canvas. 𝜏 = 𝑟𝐹 sin […]

## Determine the magnitude and direction of the magnetic force acting on the length of 1 m of wires, if the currents are carried a) in the same direction, b) in the opposite direction.

Physics Homework#1, T,3 Answer the following questions (show your full work) Use the diagram given to find the force per unit length between the two wires shown.   The distance between two parallel wires carrying currents of 10 A and 20 A is 10 cm. Determine the magnitude and direction of the magnetic force acting […]

## Comment on the widespread use of wave and tidal power as a source of renewable energy. Does it seem reasonable? Can it be a significant part of our future energy budget?

ASSIGNMENT Consider and address any one (1) of the three (3) issues below. You may only choose one. You must argue in favor of a specific position. For example, if the issue were to consider the possibility of solar panels to generate a sufficiently large amount of electricity to reduce significantly our reliance on fossil […]

## Velocity and Acceleration-Distinguish between the terms uniform velocity and uniform acceleration.

Velocity and Acceleration Distinguish between the terms uniform velocity and uniform acceleration.

## What as the apparent separation of the slits when the dial gauge read 75 based on the millimeter scale in the image?

Interference of light Explain why the separation of the two slits is 2h. If the two beams have paths that differ by exactly one wavelength λ in Young’s double slit, do they add constructively to make a bright interference region, or destructively to make a dark one? If the two beams have paths that differ […]
