Suppose you walk 16m straight west and then 22.5m straight north. How far are you in meters from your starting point (numeric value only, no expression)? What is the compass direction, in degrees measured West of North, of a line connecting your starting point to your final position?
Water is pumped into a storage tank from a well delivering 17 gallons of water in 33 seconds throughout a pipe of 1.0 in 0.2 cross-sectional area. What is the average velocity of the water in the pipe as the water is pumped from the well?
What deceleration would the car require to stop in time? What acceleration would the car require to clear the intersection before the light turns red?
A car which is traveling at a fix speed of 15.0 m/s, takes 11.0 sec to complete each lap as it travels around a circular track. Evaluate the centripetal acceleration of the car
A betatron is a charged particle accelerator that works by generating an induced electric field to accelerate the charged particles. What is the amplitude of the oscillating electric field at a distance 0.62 m from the axis of the betatron
A 100-turn square wire coil of area 0.04m2 rotates about a vertical axis at 1500 rev/min, as indicated. The horizontal component of the Earth's magnetic field at the location of the loop is 2.0 × 10-5 T. compute the maximum emf induced in the coil..
The stretched length of a spring is 4.28 m. A ribbon is tied aroundthe spring at a point near its center. A pulse created at one endof the spring makes 13 back-and-forth trips along the spring in6.59 s. With what frequency does the ribbon go up and..
A 200kg car is traveling 22 m/s. Find the kinetic energy in Joules. b) The same car is lifted vertically upward and then dropped from rest. Find the height from which it is dropped if it strikes the ground at 22 m/s (neglect air resistance).
Without weighing themselves or taking any other measurements, how could the girls use their superior knowledge of torque generation to complete the task success
A tennis ball of mass 57.0 g is held just above a basketballof mass 590 g. With their centers vertically aligned, bothballs are released from rest at the same time, to fall through adistance of 2.00 m. Find the magnitude of the downward velocity wi..
