Newton's First and Second Laws of Motion:Question 5
A student is subjected to a reaction force of 10 N northward from a 5
kg block while pushing the block over a smooth, level surface.
Ignoring friction, what is the acceleration of the block?
Select one:
2
northward
southward
m
0.5

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

i don't know that i agree with that but what's the question ?

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
