Q. plan,design and conduct a practical investigation to determine the value of an unknown resistor 2.hand in your draft plan and design prior to conducting your investigation. 3.write a scientific report and hand it in for assessment.Q. Suppose the current in the coaxial cable, see the figure , is not uniformly distributed, but instead the current density varies linearly with distance from the center: for the inner conductor and for the outer conductor. Each conductor still carries the same total current in opposite directions. Determine the magnetic field at a distance R from the axis.
In the lungs there are tiny sacs of air that are called alveoli. An oxygen molecule (mass = 5.30 x 10-26 kg) is trapped within a sac, and the uncertainty in its position is 0.140mm. What is the minimum improbability in the velocity of this oxygen ..
Find out the frequency of a sound wave moving through iron at 25 degrees Celsius with a wavelength of 0.601m.
Introductory Mechanics: Calculate the smallest coefficient of static friction
A kayaker needs to paddle north across a 200 wide harbor. The tide is going out, creating a tidal current that flows east at 2.0. The kayaker can paddle with a speed of 3.0. In which direction must he paddle in order to travel straight across the har..
A compound microscope has an objective lens of focal length 10.50 with an eyepiece of focal length 14.80, and it produces its final image at infinity. The object to be viewed is placed 2.00 beyond the focal point of objective lens.
What are speed and direction of the ball after the collision
An electron moves in the positive x-direction a distance of 2.38 m in 2.95 x10-8 s, bounces off a moving proton, and then moves in the opposite direction a distance of 1.63m in 3.53x 10-8 s.
A lighthouse that rises 49 above the surface of water sits on a rocky cliff that extends 19 from its base. A sailor on the deck of a ship sights the top of the lighthouse at the angle of 30.0 above the horizontal.
If coefficient of kinetic friction between the box and the floor is 0.570, how long does it take to move the box 4.00 m, starting from rest.
Elucidate the spacing between peaks
In the figure, suppose that the separation between speakers A and B is 5.90 m and the speakers are vibrating in phase. They are playing identical 110-Hz tones, and the speed of sound is 343 m/s.
A luge and its rider, with a total mass of 104 kg, emerges from a downhill track onto a horizontal straight track with the initial speed of 53 m/s. suppose they stop with the constant deceleration of 2.30 m/s2.
