Not exactly sure what the last part of the question is but in regular scientific notation it would be " 8.0123x10 (to the 4th power)"
there wasnt a sign for the exponent lol
Answer:
age of the site is 15411.75 years old
Explanation:
Given data
plant or animal dies = 14C
time period = 5730 year
carbon = 15.5%
to find out
age (in years) of the ancient site
solution
we know that Final value = Initial value ×
here n is half life passed
so for 15.5%
15.5% = 100% of
0.155 = 1 ×
now take log both side
log 0.155 = log
n = log 0.155 / log 0.5
n = 2.68966
we know here 5730 years in half life
so for 2.68966 half-lives = 2.68966 × 5730 = 15411.7518
age of the site is 15411.75 years old
If the bulbs are in series, then there are no 'branches' ... just
a single current path all the way around.
If the two bulbs have equal resistance, then no matter what their
actual resistance is, the supply voltage will divide equally between
them ... 6 volts across each bulb.
Answer:
<h2>300 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
PE = 2 × 10 × 15
We have the final answer as
<h3>300 J</h3>

The charge on each coin is equal to
Given the following data:
Force = 2.0 Newton
Radius = 1.5 meters
To determine the charge on each coin, we would apply the law of electrostatic forces:
Mathematically, the law of electrostatic forces is given by the formula:
Note: (since the coin carry identical electric charges).
Therefore, the formula becomes:
Making q the subject of formula, we have:
Substituting the given parameters into the formula, we have;
