Every substance has a specific value of heat required to change the temperature of 1 gram of the substance by 1 degree celsius. specific heat is found by using the equation q=mcδt, where q represents heat in joules, m represents mass in grams, δt is the change in temperature in celsius, and c is the coefficient constant for a substance. find the units for the coefficient c.

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false
