Apacking crate rests on a horizontal surface. it is acted on by three horizontal forces: 600 n to the left, 200 n to the right, and friction. the weight of the crate is 400 n. if the 600-n force is removed, the resultant force acting on the block is?
zero.
200 n to the right.
200 n to the left.
impossible to determine from the information given.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyerβs error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
