The correct answer is C. 2, 1
Explanation:
In physics, protons along with neutrons and electrons are the particles that compose atoms which are the basic unit of matter. Protons different neutron have a positive charge and along with neutrons create the nucleus of the atoms. In terms of composition, protons are made up of three quarks (elementary particles) that are divided into two up quarks and one down quark that are two types of quarks with low mass. According to this, it can be concluded protons are made up fo 2 up quarks and 1 down quark.
find the anguler momentum of a body if K.E = 4 jule and M.I = 2kg m2.
Answers
Answer:
KE = 1/2 I ω^2
Given I = 2 kg m^2 and KE = 4 J
ω = (2 KE / I)^1/2 = (2 * 4 / 2)^1/2 = 2^1/2 sec
P = I ω definition of angular momentum
P = 2 kg m^2 * (2 KE / I)^1/2 / sec = 2 * 2^1/2 kg m^2 / sec
In real-life circuits, there will always be more than one capacitor or resistor included. In a circuit with multiple capacitors, the total or equivalent capacitance can be calculated to represent all the capacitors as a single one with a capacitance called either the "net capacitance" or "equivalent capacitance". The formula to use to calculate this net capacitance is dependent on whether the capacitors are in series or in parallel.
Answers
The equivalent capacitance of the three capacitors shown in the figure is equal to 7.5 microfarad.
Capacitance is the ability to store charge. It is visible from the figure that capacitance C1 = 10μF, C2 = 20μF and C3 = 10μF. The capacitors C1 and C2 are connected in parallel. Therefore we first take the equivalent capacitance of C1 and C2, which can be calculated as follows;
Now, the equivalent capacitance of C12 and C3 is calculated. Since they are connected in series, so the formula will be reciprocal sum of the capacitance C12 and C3, which is shown below:
Hence, the equivalent capacitance will be equal to 7.5 microfarad units.

Answer:
40g
Explanation:
Mass = density x volume
= 2 x 20
= 40g
Answer:
m = V × ρ
= 20 milliliter × 2 gram/cubic meter
= 2.0E-5 cubic meter × 2 gram/cubic meter
= 4.0E-5 gram
= 4.0E-8 kilogram
Explanation:
The density of a material, typically denoted using the Greek symbol ρ, is defined as its mass per unit volume.
ρ =
m
V
where:
ρ is the density
m is the mass
V is the volume
The calculation of density is quite straightforward. However, it is important to pay special attention to the units used for density calculations. There are many different ways to express density, and not using or converting into the proper units will result in an incorrect value. It is useful to carefully write out whatever values are being worked with, including units, and perform dimensional analysis to ensure that the final result has units of mass volume. Note that density is also affected by pressure and temperature.
