Given that,
Speed of first bicycle = 9 mph
Speed of second bicycle = 5 mph
Suppose the length of the circle 24 miles.
We need to find the relative velocity
Using formula of relative velocity
Put the value into the formula
We need to calculate the time
Using formula of time
We need to calculate the distance of the points where the two bicycles meet
Using formula of distance
For first bicycles,
For second bicycles,
Hence, The points where the two bicycles meet after every 6hr at 30 miles and 54 miles.
Answer: where is the picture?
Step-by-step explanation:
Answer:
0.2 kilograms * 9 =
1.8 kilograms
Step-by-step explanation:) hope this helps
1.8 kilos=3.96832 pounds
Medium takes one seventh as much as a large, one seventh of eight ninths pints of milk.
What is 1/7 of 8/9?
Answer:
B. increase by a factor of 3.
Step-by-step explanation:
According to ohms law:
V ∝ R
Vo = IoR
R = Vo/Io ... (1)
Vo is the initial potential difference/voltage
Io is the initial current across the resistor
R is the resistance
If for an Ohmic conductor, we triple the voltage without changing the resistance:
New voltage V1 = 3Vo
New voltage V1 = I1R (resistance doesn't change)
I1 is the current after the voltage has tripled
3Vo = I1R
R = 3Vo/I1... (2)
Equating both resistances in 1 and 2 since resistance doesn't change we have:
Vo/Io = 3Vo/I1
1/Io = 3/I1
I1/Io = 3
New current I1 = 3Io
This shows that tripling the voltage increases the current by factor of 3
