Answer:weak nuclear
Explanation:
There weak nuclear force is responsible for allowing carbon-14 to become stable
<h2>Answer: decibels
</h2>
The decibel is the relation between two values: the pressure produced by a sound wave and a pressure taken as a reference. Resulting in a dimensionless value.
It should be noted that itself<u> is not a unit of measure</u>, since in reality the unit is bel (which <u>is not part of the International System of Units</u>) in honor of Alexander Graham Bell.
However, given the amplitude of the measured elements in practice, its submultiple, the decibel, is used. That is, this quotient is a logarithmic expression, where

See explanation for step by step explanations.
Explanation:
Let X be the mass of a randomly selected resistor
The probability density function is given as
, 80<x<120
=0, otherwise
a) By using the given pdf we have to find the probability of the resistors having resistance less than 90
=
=
=0.0625
the probability of the resistors having resistance less than 90 is 0.0625
Step 2 of 4<
/p>
b) we have to find the mean resistance
Mean=
=
=
=106.67
The mean resistance is 106.67
The momentum of the first truck is 40,000 kgm/s.
The velocity of the second truck with equal momentum is 28.57 m/s.
The given parameters:
- Mass of the first truck, m = 4000 kg
- Velocity of the first truck, v = 10 m/s
- Mass of the second truck, m = 1,400 kg
<h3>What is momentum?</h3>
- Momentum is defined as the product of mass and velocity.
The momentum of the first truck is calculated as follows;
P = mv
P = 4000 x 10
P = 40,000 kgm/s
The velocity of the second truck with equal momentum is calculated as follows;
The <u>complete question</u> is below:
- A 4,000-kilogram truck travels in straight line at 10.0 m/s, What is its momentum?
- A 1,400-kilogram car is also traveling in a straight line. Its momentum is equal to that of the truck in the previous question. What is the velocity of the car?

Answer:
1.92×10^-9 microCoulomb
Explanation:
Elemental charge = 1.6×10^-19 Coulomb
Charge of balloon after 12,000 electrons have been removed from it = 12,000 × 1.6×10^-19 Coulomb = 1.92×10^-15 Coulomb = 1.92×10^-15/10^-6 = 1.92×10^-9 microCoulomb
