Answer:
Joining a club and getting a hobby
Explanation:
Join a club if you want to meet people, and when they choose a hobby it should be more than just gardening, because gardening sucks in the long term and it doesn't fill that gap. I know because my grandma did it and she is still sad.
Explanation:
Given info: The Number of turns in the wire is 580 the diameter of
tube is
and the length of the tube up to which wire is wrapped is
.
Formula to calculate the inductance of the coil is,
Here,
is inductance of the coil.
is the permittivity.
is the number of turns.
is the length up to which wire is wrapped.
is the cross sectional area of the coil.
The expression for the area is,
Substitute
in equation (1).
Substitute 580 for
Conclusion:
Therefore, the inductance of the given single conductor wire is
Given info: The rate of increasing current
and the inductance of the coil
.
The generated emf is,
Here,
is the generated emf.
Conclusion:
Therefore, the generated emf is
.
Answer:
the ropeless skipping rope and many other
Explanation:
The given data is as follows.
Concentration of caffeine = 2.97 mg/oz
Number of oz in a can = 12 oz
Therefore, the concentration of caffeine in one can is calculated as follows.
=
mg
= 35.64 mg
= ![35.64 \times 10^{-3} g](https://tex.z-dn.net/?f=35.64%20%5Ctimes%2010%5E%7B-3%7D%20g)
Since, it is given that lethal dose is 10.0 g. Hence, number of cans are calculated as follows.
No. of cans = ![\frac{\text{Lethal dose}}{\text{concentration in one can}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BLethal%20dose%7D%7D%7B%5Ctext%7Bconcentration%20in%20one%20can%7D%7D)
= ![\frac{10 g}{35.64 \times 10^{-3} g}](https://tex.z-dn.net/?f=%5Cfrac%7B10%20g%7D%7B35.64%20%5Ctimes%2010%5E%7B-3%7D%20g%7D)
= 280.58
= 281 (approx)
Thus, we can conclude that 281 cans of soda would be lethal.
