Which if the following is a requirement that units in a correct formula or equation must always satisfy?
a) each unit in the formula, expressed in si base units, must be the same.
b) all units must be units only of mass, length, or time.
c) the units on both sides of the equal sign, expressed in si base units, must be the same.
d) all masses must be in kilograms, all lengths in meters, and all times in seconds.

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

An object has a weight of 500 on earth what is the mass of this object

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?
