Answer: clean out the wound before putting a bandage on
Explanation:
Answer: 75.8 %
Explanation:
Half-life of tritium= 12.33 years
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the age of the sample:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = age of sample = 5 years
a = let initial amount of the reactant = 100 g
a - x = amount left after decay process = a g
Now put all the given values in above equation, we get
Thus 75.8 percentage of a sample will remain after 5 years have passed.
You need to know the capacitance of the capacitor, C.
The voltage after time t is equal to the original voltage times e^(t/RC) where R is the resistance that you are trying to find.
Hi there!
We can use the following equation to calculate the magnetic field inside of a solenoid:
B = Magnetic Field Strength (T)
n = number of loops PER LENGTH
i = current through solenoid (A)
μ₀ = Permeability of free space (4π × 10⁻⁷ Tm/A)
First, we can solve for 'n' given 'N' (total # of loops) and L (length of solenoid).
Now, we can calculate the magnetic field:
