A drone, flying 300m above ground, observes a man walking on a road in a cold night (0°C). how many photons/sec does it receive from the man and from a similar surface of road
The experiment you did in lab is repeated, using a uniform metal bar that is 80.0 cm long instead of the meterstick. Since the bar is uniform, What is the mass of the bar?
A uniform electric field of magnitude 256 V/m is directed in the negative y direction. A +12.9 uC charge moves from the origin to the point (x, y) = (20.0cm, 45.6 cm). What was the change in the potential energy of this charge? Through what potent..
Can anyone please help me figure out this question, thanks in advance. What is the magnetic force exerted on a 2.85 m length of wire carrying a current of 0.595 A
A 41 kg crate, starting from rest, is pulled across a floor with the constant horizontal force of 250 N. For the first 10m the floor is frictionless, and for the next 11.00 m the coefficient of friction is 0.17. What is the final speed of the crat..
After the right string is cut, the meterstick swings down to where it is vertical for an instant before it swings back up in the other direction. What is the angular speed when the meterstick is vertical
David is driving a steady 25 m/s when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.8 m/s^2 at the instant when David passes.
A helicopter is ascending vertically with a speed of 5.02m/s. At a height of 140m above the Earth, a package is dropped from the window. How much time does it take for the package to reach ground.
When the cylinder is rotating at 2.0 revolutions per second, determine the magnitude of the centripetal acceleration at the outer wall?
Three wires are arranged parallel to each other. Wire 1 sits at x = -2.5m with a current I1 = 3.0A directed into the page, Determine the location of wire 3 and the direction of the current such that the net magnetic force acting on wire 3 is zero
Two students are on a balcony a distance h above the street. One student throws a ball vertically downward at a speed vi; at the same time, the other student throws a ball vertically upward at the same speed. Answer the following symbolically in t..
A mass-spring system oscillates with an amplitude of 5.50cm. If the spring constant is 247N/m and the mass is 584g, determine the mechanical energy of the system
