Calculate the pressure exerted on the heel of a boy’s foot if the boy weighs 320 n and he lands on one heel which has an area of 0.16 m²

Carbon 14 is a naturally occurring stable

Which situation will produce the greatest change of momentum

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?
