Pedro is planning to model how changes in weather affect evaporation from lakes. for his second experiment, he wants to test how winds affect the evaporation rate. he places one beaker with 300 ml of water in an area away from any fans, and he places another beaker with 300 ml of water near a small fan.

what is the dependent variable in pedro's experiment?

a. volume of water
b. evaporation rate
c. temperature
d. movement of air

Your answer is 120miles 

The answer is d, you can easily test a theory! hope i you : )

Answerit decreases;

Friction force is equal to the net force of the car.             fn                           |ff< ·                       |                     fgfg and fn cancel out.55 km/h is 15.2778 m/s. this is the initial velocityfinal velocity is 0 m/sfind acceleration using kinematic equationv² = v₀² + 2adsince v = 00 = v₀² + 2ada = -v₀²/(2d)a = -(15.2778 m/s)/(2 * 38m) a = -3.2418 m/s²find net force and you find friction.f = ma f = (1165 .2418 m/s²)f = 3776.7 n = ffw = ff · dw = (3776.7 n)(38 m)w = -1.4 × 10^5 jthe friction forces do 1.4 × 10^5 j of work on the car
