Speed v = initial speed u + acceleration a x time t
v=u+at = 2 + 4*3 = 14 m/s
The answer completely depends on the number that belongs in the space before the word "microfarad".
Gravity ALWAYS does that, and electrostatic force does it when two objects have opposite charges.
Answer:
W = 19.845 J
Explanation:
Work is defined as W = Fdcos
, where F is the force exerted and d is the distance. Because the direction the ball is falling is the same direction as the force itself, = 0 deg, and since cos(0) = 1, this equation is equivalent to W = Fd. In this case, the force exerted is the weight force, which is equivalent to m * g. Substituting you get:
W = mgd = 0.810 kg * 9.8 m/s^2 * 2.5m
W = 19.845 J
B.temperature is an indirect measurement of the heat energy in a substance
