Physics

The graph below plots the temperature and luminosity of stars on the main sequence. (2 points)Four locations (A, B, C and D) are graphed on a curve representing luminosity vs temperature. The curve begins are high luminosity and high temperature decreasing in luminosity and temperature as it approaches the right side of the curve. From left to right are points representing Location A, Location B, Location C and Location D.At what location is the star with the least initial mass most likely to be found?Location ALocation BLocation CLocation D

A proton travels through uniform magnetic and electric fields. The magnetic field is in the negative x direction and has a magnitude of 2.48 mT. At one instant the velocity of the proton is in the positive y direction and has a magnitude of 1840 m/s. At that instant, what is the magnitude of the net force acting on the proton if the electric field is (a) in the positive z direction and has a magnitude of 5.19 V/m, (b) in the negative z direction and has a magnitude of 5.19 V/m, and (c) in the positive x direction and has a magnitude of 5.19 V/m

The length of stereocilia actually vary from 10 to 50 micrometers. Again, assuming that they behave like simple pendula, over what frequency range of sound waves would they resonate. (The actual frequency range of human hearing is 20 Hz - 20,000 Hz, so there certainly must be other mechanisms involved in determining the frequency of these being the pendular model is rather oversimplified.)a. About 70 Hz -160 Hz. b. About 440 Hz - 1000 Hz. c. About 20 Hz - 50 Hz. d. About 0.07 to 0.16 Hz.

The driver of a car wishes to pass a truck that is traveling at a constant speed of 19.3 m/s . Initially, the car is also traveling at a speed 19.3m/s and its front bumper is a distance 25.0m behind the truck's rear bumper. The car begins accelerating at a constant acceleration 0.560m/s^2 , then pulls back into the truck's lane when the rear of the car is a distance 26.5m ahead of the front of the truck. The car is of length 4.50m and the truck is of length 20.7m . Part A) How much time is required for the car to pass the truck? Part B ) What distance does the car travel during this time? Part C) What is the final speed of the car?
