Chemical energy (calories) is converted by your body walking on the surface into mechanical/kinetic energy
Answer:
B.The linear velocity of the gears is the same. The linear velocity is 432π centimeters per minute.
Explanation:
As we know that the small gear completes 24 revolutions in 20 seconds
so the angular speed of the smaller gear is given as


Now we know that the tangential speed of the chain is given as

so we have



Since both gears are connected by same chain so both have same linear speed and hence correct answer will be
B.The linear velocity of the gears is the same. The linear velocity is 432π centimeters per minute.
You would divide 6 into 1000 so your answer is B. 166
Answer:
Part a)
Rate of charge flow is known as electric current
Part b)
Average current flow is

Part c)
As we know that current density is current per unit area

Explanation:
As we know that angular frequency of rotation is

now by basic definition of electric current
Part a)
Rate of charge flow is known as electric current

so here we have


Part b)
here we know that



now we have


Part c)
As we know that current density is current per unit area
So we have
