In a time of T seconds, a motorcycle can accelerate from rest to the speed v.
(a) Determine the amount of time (in terms of T) required for it to accelerate from v to 9v if the power output remains constant.
?t =
(b) Determine the speed of the motorcycle (in terms of v) 2T after starting.
vf =
A 90° inverted cone contains water as shown. The volume of the water in the cone is given by V = (p/3) h3. The original depth of the water is 10 cm. A block with a volume of 200 cm3 and a specific gravity of 0.6 is floated in the water. Find the c..
For this question, I got 196 nC but apparently its -196 nC and i was hoping you could explain why the answer is negative: A styrofoam ball of mass 0.120 g is placed in an electric field of 6000 N/C pointing downward. What charge must be placed on ..
