Two semi-infinite grounded conducting planes intersect at 60 degrees. A point charge is situated inside this wedge-shaped region.
(a) Find image charges to obtain the potential between the conductors.
(b) Can you use the result of part (a) to obtain the Green function for the Dirichlet problem between the planes? No explicit calculation is required; just explain

1. A large, two-story office building has a first floor which measures 500 ft by 750 ft and a second story which is 500 ft by 500 ft. This building used 76,650 GWh of electricity last year and 120,035 therms of natural gas.

   1. a) What is the EUI of the building? How does this compare to similar buildings?

   2. b) Currently the office encourages carpooling and public transportation and therefore does not have a parking structure attached. They are considering adding this as an amenity to their employees. How does an unheated, 145,000 square feet parking garage change the EUI? How might this

      impact an energy audit of the building?

   3. c) By 2025, the company would like to add solar panels on the roof of the building to create on-site

      electricity. These panels are projected to create a minimum of 20,000 kWh, annually. What is thebuilding’s new EUI?

testing a scientific hypothesis involves four main steps. examine each of these steps in detail.

An accelerator in an automobile is defined as anything a person directly
interacts with, resulting in a change in motion of the vehicle. Your mission is to list at least 12
accelerators that you would find in any standard automobile. You must accurately describe
each accelerator and state the external force that the accelerator indirectly affects. You
should also show the external forces that directly cause each acceleration using adequate
diagrams and explanation. Please, only consider standard cars or trucks; the Batmobile,
monster trucks, or even police vehicles are not standard automobiles.

A spring that has a force constant of 1050 N/m is mounted vertically on the ground. A block of mass 1.40 kg is dropped from rest from height of 1.40 m above the free end of the spring. By what distance does the spring compress?

a. Two point charges each of magnitude +5.010-9 C are placed 8.0 cm apart in air. Calculate, i. the electric potential, and ii. the electric field strength at a point, P which is 5.0 cm away from each charge. b. An electron of charge 1.610-19 C moves from a point midway between the charges and on the line joining them, to point P. i. Calculate the work done. ii. Discuss the energy changes in the process

Research 3 types of technology that we have in our world that are related to either Kepler's Laws or The Universal Law of Gravity. The technology can be directly related to these topics or just a snowball effect and only somewhat related to them.
Yo should include:
3 examples of technology
Explanation how the technology helps humans (or will help them in future)
Explanation how the tecnology is related to Kepler's Laws or The Universal Law of Gravity

Indicate whether the following statements are true or false. (Select T-True, F-False. If the first is T and the rest F, enter TFFFFF).

A) A white dwarf is the remnant of the star's core visible after the outer layers have been ejected.

B) A planetary nebula is made of hot gas that shows emission line spectra.

C) A planetary nebula forms when a star violently explodes.

D) White dwarfs are small dense objects about the size of the Earth.

E) White dwarfs are composed mostly of hydrogen.

F) A planetary nebula is the remnant of the outer envelope of a star

Choose the correct statements from the following list referring to white dwarfs. (Give ALL correct answers, i.e., B, AC, BCD...)

A) White dwarfs are less dense than red giants.

B) White dwarfs cool slowly because they are small and eventually fade-out to become black dwarfs.

C) The pressure that balances gravity in a white dwarf is called degenerate electron pressure.

D) Stars with a mass like the Sun will end up as a white dwarf star.

E) White dwarfs with mass greater than 1.4 times the Sun's mass cannot exist.

F) The power source of white dwarfs is left-over heat. G) White dwarfs are the coolest main sequence stars.

A gigantic parallel plate capacitor with area of plates of 1.1x108 m 2 and separated by distance 1500 m connected to source of a potential difference 35 million volts. Define potential energy of the capacitor.

what will be transient telegrapher's equation solution using laplace transforms if R,G parameter is not zero.

Where R= RESISTOR OF WIRE AND G= conductance between line.

A converging lens forms an image 20 centimeters  high of an object that is 5 centimeters high.

part a calculate the magnification factor m of the lens

part b Explain how you can calculate the distance from the object if you know the lens has a focal length of  f centimeters.

part c If the lens has a focal length of 10 centimeters calculate the distance to the image if the object is placed at a distance of 25 centimeters from the lens.

part d Indicate if the image formed in part c is  real or virtual and if it is upright or inverted.

The mass of Uranus is 8.68 x 10²⁵ kg. That’s 14.536 times more than the mass of Earth.

What is the difference between the forces due to Uranus on a 1.0 kg mass located at the near side of Titania and at the far side of Titania? Titania has a mean radius of 789 km and a mean orbital radius about Uranus of 436,300 km. (Enter the magnitude in newtons.)

Compare this difference to the difference for Earth due to the Moon, 0.22 ✕ 10⁻⁵ N. (Tidal forces are the cause of volcanic activity on some moons.)

Calculate the mass (in kg) of the Sun based on data for Uranus's orbit. (Use G = 6.67 ✕ 10⁻¹¹ N · m²/kg² in your calculations. Round your answer to at least four significant figures.)

Compare the above calculated value with the Sun's actual mass. (Round your answer to at least three decimal places.)

A car drives around a curve with radius 420 m at a speed of 37 m/s. The road is banked at 5.4°. The mass of the car is 1500 kg. (a) What is the frictional force on the car? (b) At what speed could you drive around this curve so that the force of friction is zero?
