Answer:
It is -1.602 x 10^-19 C, and the smallest unit of charge
Step-by-step explanation:
The charge on an electron is
. The charge on electron is negative. The quantization of electric charge is :
q = ne
q is net charge
n is no of electrons
e is the electronic charge which is
. Hence, the correct option is (b).
Answer:
d ≈ 29.99 cm
Step-by-step explanation:
The volume of a cylinder can be calculated by the formula V = pi * r^2 * h.
V = pi * r^2 * h
We know the volume and the height, so we can use the formula to determine the radius, which can be used to determine the diameter.
4239 = pi * r^2 * 6 (I will add the units later | Divide both sides by 6)
706.5 = pi * r^2 (Divide both sides by pi)
706.5/pi = r^2 (Take the square root of both sides)
sqrt (706.5/pi) = r (r is the radius)
r ≈ 14.99619733762023
The diameter will be double this value.
d ≈ 29.99239467524046
d ≈ 29.99 cm
Answer:
t(99)= -2.89
Step-by-step explanation:
-To places after the decimal point is equivalent to rounding off to the nearest hundredth.
-To round off to the nearest hundredth, we check the thousandths digit:
- If the thousandths digit is less than5, we round down to the previous hundredth.
- If the thousandths digit is greater than 4, we round up to the next hundredth:
Hence,
