During a mountain climbing trip it is observed that the water used to cook a meal boils at 93 °c rather than the standard 100 °c at sea level. at what altitude are the climbers preparing their meal? (see physical properties of water (si units) and properties of the u. s. standard atmosphere (si units) for data needed to solve this problem.)

it would be kevlar ^^

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
