A = p + n (2) where n is the number of neutrons. When using atomic mass units (a.m.u.), the mass of each nucleon (proton or neutron) is 1 a.m.u, so the mass number also corresponds to the mass number.
Answer:
14.0 cm
Explanation:
Draw a free body diagram of the block. There are three forces: weight force mg pulling down, elastic force k∆L pulling down, and buoyancy ρVg pushing up.
Sum of forces in the y direction:
∑F = ma
ρVg − mg − k∆L = 0
(1000 kg/m³) (4.63 kg / 648 kg/m³) (9.8 m/s²) − (4.63 kg) (9.8 m/s²) − (176 N/m) ∆L = 0
∆L = 0.140 m
∆L = 14.0 cm
Answer:
The capacitance of a capacitor depends on the charge and voltage of a system. It is also dependent, if present, on the dielectric as well.
General Formulas and Concepts:
<u>Gauss's Law</u>
Capacitance Formula:
- <em>Q</em> denotes charge
- <em>V</em> denotes voltage
Dielectric Capacitance Formula:
- <em>C₀</em> denotes original capacitance
- <em>κ</em> denotes the dialectic constant
Explanation:
A <u>capacitor</u> <em>stores</em> charge when run through an electrical current. The <u>capacitance</u> is <em>how much </em>charge a capacitor can hold.
We can define the relationship of capacitance by using the formula. Capacitance is <em>inversely proportional</em> to the potential energy, or <u>voltage</u>, of the system. Therefore, you will need to know what the <u>charge</u> Q of the system as well has voltage V in order to find the capacitance.
If there is a dielectric involved inside the capacitance, you also must incorporate the value of the <u>dielectric constant </u>into your capacitance. A dielectric is <em>directly proportional </em>to the capacitance; the bigger the dielectric constant, the bigger capacitance, as denoted in our equation.

Unit: Gauss's Law
Average Acceleration = (change in speed) / (time for the change)
Change in speed = (ending speed) - (starting speed)
= 15 m/s - 24 m/s = -9 m/s
Acceleration = (-9 m/s) / (12 sec) = - 0.75 m/s² .
Fat has a density of 0.92 g/cm3 and soap has a density of 0.84 g/cm3. These are all properties that make fat and soap different substances.
