Alpha
Beta
Gamma
Alpha radiation is the energy carried by fast moving helium atoms.
Beta radiation is the energy of electrons released from atoms.
Gamma radiation is the energy released by radioactive or unstable atoms.

Answer:
The correct option is B)
Step-by-step explanation:
Consider the provided function.
and
We need to divide f(x) by d(x)
As we know: Dividend = Divisor × Quotient + Remainder
In the above function f(x) is dividend and divisor is d(x)
Divide the leading term of the dividend by the leading term of the divisor:
Write the calculated result in upper part of the table.
Multiply it by the divisor:
Now Subtract the dividend from the obtained result:
Again divide the leading term of the obtained remainder by the leading term of the divisor:
Write the calculated result in upper part of the table.
Multiply it by the divisor:
Subtract the dividend:
Divide the leading term of the obtained remainder by the leading term of the divisor:
Multiply it by the divisor:
Subtract the dividend:
Therefore,
Dividend =
Divisor =
Quotient =
Remainder = 0
Dividend = Divisor × Quotient + Remainder
Hence, the correct option is B)
Answer 20
Step-by-step explanation:
Answer:
The estimate of 100- year annual rainfall amount is 274.5cm
Step-by-step explanation:
From the question, x (mean) =152 ; Sx ( standard deviation) = 30, T (time) 100 years, P (period) = 1/T = 1/100 =0.01
The frequency factor is expressed as:
where w= for zero is less than P less than or equal to 0.5
w=
= 3.034
= 2.326
=2.18
=1.477
∴
=
=274.5cm
Where y represents the total number of coins and 0.5x represents the number of 5 cent coins and x represents the number of 1 cent coins...
y = 0.5x + x
= 1.5x
1/2x + 2x = 2.5x
If he exchanged 1 cent coins for 2 cent coins, he would have half the same number of 2 cent coins as he had for 5 cent coins. Instead of 2x, you would have "x" and...
y = 0.5x + 0.5x = x
y = 1x
Divide slopes..
1 / 1.5 = 2/3 or 0.67.
The answer is 2/3 so Choice B is the answer.
