Two long, charged, thin-walled, concentric cylindrical shells have radii of 4.3 and 7.0 cm. the charge per unit length is 4.8 × 10^-6 c/m on the inner shell and -6.4 × 10^-6 c/m on the outer shell. what are the (a) magnitude e and (b) direction (radially inward or outward) of the electric field at radial distance r = 6.1 cm? what are (c) e and (d) the direction at r = 12 cm?

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

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?
