B A spring whose original length is 7 mm (to the nearest mm) lengthens to 10 mm (to the nearest mm) when a force of 0.4 N pulls on it. Calculate the
spring constant of the spring.

Estimate the spring constant of the spring in a school newtonmeter with a
measurement range of 0–10 N. Show your reasoning.

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?

There are 3 ways heat can be transferred: through solids, called , through liquids and gases , called , and through electromagnetic waves, called
