A dock worker pushes a 150.0 kg crate up a ramp that is 3.00 m high and 15.00 m long into the cargo bay of a ship. He exerts a 900.0 N force parallel to the ramp. a. Find both the mechanical advantage and ideal mechanical advantage of the ramp. Show your calculations

b. What is the efficiency of the ramp? Show your calculations

c. Include a diagram

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
