The mechanical advantage of the bicycle is 0.1.
<u>Explanation:</u>
A simple machine is a machine that produces the output if we give the required input, and so the output always depends on the input force. Sometimes machines can also reduce the input force to get the required output and the ratio of output to input force is called as the mechanical advantage.
MA =
Now we have the input force = 697 N
Output force = 93 N
So Mechanical advantage can be calculated by inserting those values as, MA =
= 0.1
So the mechanical advantage of the bicycle is 0.1.
Answer:
Option (2) : Sixteen times the first cube
Explanation:
Answer:
I think the answer is electric potential.
Answer: Decreases in mass cause decreases in kinetic energy due to the aforementioned positive relationship between the two. Therefore when mass is decreased, an increase in kinetic energy is possible if velocity increases.
Answer:
BI/BII = 1
Explanation:
The magnetic field due to a solenoid is given by the following formula:
where,
B = Magnetic Field due to solenoid
μ = permeability of free space
n = No. of turns per unit length
I = current passing through the solenoid
Now for the first solenoid:
For the second solenoid:
Dividing both equations:
here, no. of turns and the current passing through each solenoid is same:
n₁ = n₂ and I₁ = I₂
Therefore,
<u>BI/BII = 1</u>
