if you were to expend 10 J of work to push a 1-C charge against an electric field, what would be its change of voltage?
nd the electric field at the origin, point O. Give the x and y components of the electric field as an ordered pair. Express your answer in newtons per coulomb to three significant figures. Keep in mind that an x component that points to the right is positive and a y component that points upward...
A plane flies 335 km due south, then turns and flies 616 km at a heading north of east, until it's due east of its starting point. If the plane now turns and heads for home, how far will it have to go?
A sportscar, Fiasco I, can accelerate uniformly to 12mi/h in 30s. Its maximum braking rate cannot exceed .7g. What is the minimum time required to go 1/2mi, assuming it begins and ends at rest?
A small steel ball bearing with a mass of 13.0 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.33 m. Calculate the horizontal distance the ball would travel if the same spring were aimed 32.0 deg from the horizontal.
A plastic rod is rubbed against a wool shirt,thereby acquiring a charge of 4.9 C.The charge on an electron is 1.6 10 19 C.How many electrons are transferred from the wool shirt to the plastic rod?
A rifle is aimed horizontally at a target 46.0 m away. The bullet hits the target 1.90 cm below the aim point.What was the bullet's flight time?What was the bullet's speed as it left the barrel?
Figure 21-35 shows electrons 1 and 2 on an x-axis and charged ions 3 and 4 of identical charge -q and at identical angles . electron 2 free to move the other three particles are fixed

Tips for Asking Questions
- Provide any and all relevant background materials. Attach any necessary files to ensure your Tutor has all the required information to answer your question as completely as possible.
- Set a compelling price. While our Tutors are eager to answer your questions, offering a compelling price speeds up the process by avoiding any unnecessary price negotiations.
1. Can you show me step by step how to solve this problem?:
- The Earth’s rate of rotation is constantly decreasing, causing the day to increase in duration. In the year 2000 the Earth takes about 0.548 s longer to complete 365 revolutions than it did in the year 1900.
- (a) What is the average angular acceleration of the Earth?
- (b) If this average acceleration remains constant, in what year will the Earths rotation come to rest?
2. I do not understand this Ideal Gas Law and Kinetic Theory question. Can you help me set it up?
- A spherical balloon is made from a material whose mass is 3.00-kg. The thickness of the material is negligible compared to the 1.5-m radius of the balloon. The balloon is filled with helium (He) at a temperature of 305-degrees K and just floats in the air, neither rising nor falling. The density of the surrounding air is 1.19-kg/m^3. Find the absolute pressure of the helium gas
