A bicycle odometer which counts revolutions and is calibrated to report distance traveled is attached near the wheel axle and is
1 answer:
Answer:
each rotation of the smaller wheel will show 84.382-75.3982=8.9838 inches more than the actual distance
Explanation:
d = Diameter of the wheel
The distance traveled in one rotation of the wheel is the circumference of the wheel
When diameter is 24 inches
Therefore, each rotation of the smaller wheel will show 84.382-75.3982=8.9838 inches more than the actual distance

Answer: The chemical formula for the compound of these two elements is
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here metal lead is having an oxidation state of +4 called as cation and sulphur non metal has oxidation state of -2 called as
. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral

Answer:
x' = 1.01 m
Explanation:
given,
mass suspended on the spring, m = 0.40 Kg
stretches to distance, x = 10 cm = 0. 1 m
now,
we know
m g = k x
where k is spring constant
0.4 x 9.8 = k x 0.1
k = 39.2 N/m
now, when second mass is attached to the spring work is equal to 20 J
work done by the spring is equal to
x'² = 1.0204
x' = 1.01 m
hence, the spring is stretched to 1.01 m from the second mass.
