<span>The correct option is C. Energy cannot be created or destroyed. This statement is known as law of conservation of energy, and it implies that whenever a certain form of energy does change, the loss of this form of energy must have converted into an another type of energy. A typical example is an object falling to the ground: initially, the object has gravitational potential energy. As the object falls down, it loses potential energy (since its altitude from the grounf decreases), but it acquires kinetic energy (because its velocity increases). In this example, potential energy has converted into kinetic energy, but the total energy of the object has remained constant.</span>

Answer: He didn't invent printing. He didn't even invent movable type. He often ran into legal trouble and, when he died in 1468, he did so with little money or glory.
Explanation:
Answer:
a)
14 rad/s
b)
11.2 m/s
Explanation:
a)
d = diameter of tire = 0.80 m
r = radius of tire = (0.5) d = (0.5) (0.80) = 0.40 m
v = speed of bicycle = 5.6 m/s
w = angular speed of the tire
Speed of cycle is given as
v = r w
5.6 = (0.40) w
w = 14 rad/s
b)
v' = speed of blue dot
Speed blue of dot is given as
v' = v + rw
v' = 5.6 + (0.40) (14)
v' = 11.2 m/s
