Question Theoretically, why does a decrease in resistance result in an increase in current?? Like not just referencing the equation V=IR but explain it with theory please…

A motorcyclist is trying to leap across a canyon by

Question A motorcyclist is trying to leap across a canyon by driving horizontally of the cliff that is 70.0 m high at 38.0 m/s. Ignoring air resistance, use energy conservation to find the speed with which the cycle strikes the ground at a height of 35.0m on the other side of the canyon. You do not need to know how wide the canyon is!

  1. During a rainstorm, rain comes straight down with a velocity

Question

  1. During a rainstorm, rain comes straight down with a velocity Vi = -15 m/s and hits the roof of a car perpendicularly. The mass of the rain per second that strikes the roof is 0.060 kg every second. Assuming that the rain comes to rest upon striking the car (Vf = 0 m/s), find the average force exerted by the rain on the roof during a 3 second time interval.

Question Your whole family has taken showers before you, dropping the temperature in the water heater to 18 degrees Celsius. If the water heater holds 150 kg of water, how much energy will it take to bring it to 50 degrees Celsius? If the energy is supplied by a 5 kW electric heating element, how long will it take? 

The left end of a long glass rod is 6.00

Question The left end of a long glass rod is 6.00 cm in diameter with an index of refraction of 1.60. It is ground and polished to a convex hemispherical surface with a radius of 4.00 cm. An object in the form of an arrow 1.50 mm tall, pointing up at right angles to the axis of the rod, is located on the axis 24.0 cm to the left of the vertex of the convex surface (similar to the situation in the class notes). Find the position and height of the image of the arrow formed by paraxial rays incident on the convex surface. Is the image erect or inverted?

An object is placed 16.0 cm from a thin lens.

Question An object is placed 16.0 cm from a thin lens. The image forms 12.0 cm from the lens on the same side as the object (a) What is the focal length of the lens? Is the lens converging or diverging? (b) If the object is 8.50 mm tall, how tall is the image? Is it erect or inverted (c) Draw a diagram indicating the principal rays involved your analysis of this situation.

Use the ruler and speed meter to take some measurements

Question Use the ruler and speed meter to take some measurements for the surface of the water inside the tank and the stream of water at its minimum height (with the hose at an angle). Plug these numbers into Bernoulli’s equation to see whether Bernoulli’s equation holds true in this case: What is Bernoulli’s equation, and how can I use it to take a measurement of a hose that’s coming out and down from a water tower and shooting water straight up out of the hoseo?

A pair of metal plates, mounted 1.0cm apart on insulators,

Question  A pair of metal plates, mounted 1.0cm apart on insulators, is charged oppositely. A test charge of 2.0 PC placed at the midpoint, M, between the plates experiences a force of6.0 x 104 N [W]a. what is the electric field intensity at M?b. what is the electric field intensity at a point 2.0mm from negative plate?c. what is the electric field intensity at a point 1.0mm from the positive plate?d. what are two possible ways in which you could double the strength of the electric field? An interference maximum is produced on a screen by two portions of a beam originally from the same source. If the light travelled entirely in air, what can be said about the path difference of the two beams?I need help with these question if you are able to help me please. I am currently enrolled in summer school so my teacher doesnt teach nor help much :/ thanks for the help, i really appreciate it.

Three long, parallel wires are located at the following coordinates in an x—y coordinate system: Wire 1 (x=0, y= 3cm), Wire 2 (11:0, y=0), and Wire 3 (x= 4cm, y=0). The currents are Il=1A into the xy-plane, 12=2A out of the xy—plane, and I3=4A into the xy- plane. (a) Draw a sketch of the situation and show the directions of the magnetic fields of wires 2 and 3 at the location of wire 1. The figure needs to be large enough to be able to neatly project those magnetic field vectors that need to be projected. (b) Find the X- and y—components of the net magnetic field in the xy—plane at the location of wire 1 due to the currents in wires 2 and 3. (c) Find the magnitude and direction of the net force exerted on a 1cm section of wire 1 by the other two wires. Draw the forces into a diagram separate from the one for point (a).

A deuteron (a proton and a neutron) has a mass of 3.34- 10‘27kg and a charge of e. The deuteron travels in a circular path with a radius of 6.96mm in a magnetic field with the magnitude 2.5T. (a) Draw the trajectory, and assuming that the magnetic field is pointing perpendicularly into the plane of the paper, mark the velocity and magnetic force. Find the speed of the deuteron. (b) Find the time required for it to make one half of a revolution. (c) Through what potential difference would the deuteron have to be accelerated to acquire this speed?

Discuss one type of wave that could be considered harmful

Question Discuss one type of wave that could be considered harmful or beneficial depending upon your viewpoint. For example, gamma knives are considered dangerous because they emit dangerous, high-energy radiation; however it is used in a medical capacity to remove tumors. In your initial post, identify the type of wave and describe both the dangers and benefits of it to society.
