Answer:

You've probably noticed that static electricity is more noticeable during the winter months. This is because the air is very dry. In the summer, the humidity and moisture in the air help electrons move more quickly, which makes it harder to build up a big static charge.

Answer: Vegetable oil has a higher heat capacity than water. Option C is correct.

It is given 10 grams of water and 10 grams of vegetable oil in separate containers. Both liquids have a temperature of 24°C. Now Jeff heats both liquids over a flame for five minutes.

It is required to find why the temperature of the oil increased more than the temperature of the water.

Heat capacity determines the heat that is supplied to the body that will be caused by heat of the body.

The vegetable oil warmed more when Jeff increased the temperature. This is because the hydrogen bonding present is responsible for this as oil catches fire easily.

Also to change the temperature of the water, we need more energy per gram of particular liquid.

Therefore, Vegetable oil has a higher heat capacity than water as water requires more energy.

The galaxy comprises of various stars. We are unlikely to find earth-like planets around halo stars in the galaxy because Halo stars need few heavy elements to create rocky planets.

A galaxy is a massive cluster of stars held together by t he effect of gravity.

Halo stars formed in an environment where there were few heavy elements to create rocky planets.

Thus, we are unlikely to find earth-like planets around halo stars in the galaxy because Halo stars need few heavy elements to create rocky planets.

Pick your direction of the perpendicular forces.

Let down be negative and up be positive.

Remember that sum of all the forces is the net force,

So for the vertical forces, we have

[tex]45 + ( - 45) = 0[/tex]

Next, pick your direction of the parallel forces.

Let right be positive and left be negative so we have

[tex]15 + ( - 45) = - 30[/tex]

So our net force is 30 N to the left

Two equivalent hybridized orbitals will form from the mixing of one s-orbital and one p-orbital, that is (sp) orbital.

Orbital is the place around nucleus where mostly the electrons are present. There are four types of orbitals are present, s, p, d, and f.

The orbitals that are formed by the mixing of these orbitals are called hybrid orbitals.

Thus, two equivalent hybridized orbitals will form from the mixing of one s-orbital and one p-orbital, that is (sp) orbital.

The charge on the particle when the 4000 v equipotential surface is 26. 0 cm farther from a positively charged particle than the 5000 v equipotential surface is 2.89×10⁻⁵ nC.

The point charge can be found using the following expression.

[tex]q=\dfrac{Vr}{K}[/tex]

Here, V is the potential of a point charge, r is the distance and K is the coulombs constant.

This equation can also be given as,

[tex]r=K\dfrac{q}{V}[/tex]

The 4000 V equipotential surface is 26.0 cm farther from a positively charged particle than the 5000 v equipotential surface. For this case, the distance at both point is,

[tex]r_1=K\dfrac{q}{V_1}\\r_2=K\dfrac{q}{V_2}[/tex]

Subtract both the distance which is equal to 26 cm.

[tex]r_1-r_2=K\dfrac{q}{V_1}-K\dfrac{q}{V_2}\\26=Kq(\dfrac{1}{V_1}-\dfrac{1}{V_2})\\26=(9\times10^9)q(\dfrac{1}{4000}-\dfrac{1}{5000})\\q=2.89\times10^{-14}\rm\; C\\q=2.89\times10^{-5}\rm\; nC[/tex]

Thus, the charge on the particle when the 4000 v equipotential surface is 26. 0 cm farther from a positively charged particle than the 5000 v equipotential surface is 2.89×10⁻⁵ nC.

The given statement is false. Because the induced emf is dependent on the number of coil.  

According to  Faraday's law of electromagnetic induction the rate of change of magnetic flux link with coil is responsible for generating emf in the coil result in the flow of amount of current .

So in order to increase the current we need to increase the EMF;

so we can increase it by;

1) Increasing the number of turns

2) Increase the area of the loop

3) By moving the magnet faster

The magnitude of the circuit current is 0.20 A. The value of the current in the circuit is found with the help of the ohm's law.

Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

All the resistance combined in the series so that the equivalent resistance is;

[tex]\rm R_{eq}= R_1+R_2+R_3 \\\\ R_{eq}=15+21+24 \\\\ R_{eq}=60 \ ohm[/tex]

This current-voltage connection may be expressed mathematically by the Ohm's Law;

V=IR

[tex]\rm I_{total} = \frac{V}{R_{total}} \\\\ \rm I_{total} = \frac{12}{60} \\\\ I_{total} = 0.20 \ A[/tex]

Hence, the magnitude of the circuit current is 0.20 A.

Answer:

The frequency of the sound wave is 800Hz

The speed of sound in a is about 340m/s.

Velocity = frequency x wavelength

making wavelength the subject formula

wavelength = Velocity/frequency.

wavelength = 340/800

wavelength = 0.425m.

The equivalent capacitance of the combination is  [tex]\dfrac{1}{C} = \dfrac{1}{C_1}+\dfrac{1}{C_2}[/tex]  where C1 and C2 are the capacitance of both capacitors in series.

Let the capacitance of both capacitors be C1 and C2. For a series connected capacitors, same charge flows through the capacitors but different voltage flows through them.

Let Q be the amount of charge in each capacitors,

V be the voltage across each capacitors

C be the capacitance of the capacitor.

Using the formula Q = CV where V = Q/C... (1)

For the large capacitor with capacitance of the capacitor C1,

[tex]Q = C_1V_1;[/tex]

[tex]V_1 = \dfrac{Q}{C_1}...(2)[/tex]

where [tex]V_1[/tex] is the voltage across [tex]C_1,[/tex]

For the small capacitor with capacitance of the capacitor [tex]C_2[/tex],

[tex]Q = C_2V_2[/tex];

[tex]V_2 = \dfrac{Q}{C_2} ... (3)[/tex]

where [tex]V_2[/tex] is the voltage across [tex]C_2[/tex],

Total voltage V in the circuit will be;

[tex]V = V_1+V_2... (4)[/tex]

Substituting equation 1, 2 and 3 in equation 4, we have;

[tex]\dfrac{Q}{C} = \dfrac{Q}{C_1} +\dfrac{ Q}{C_2}[/tex]

[tex]\dfrac{Q}{C} = Q({\dfrac{1}{C_1}+\dfrac{1}{C_2})[/tex]

Since change Q is the same for both capacitors since they are in series, they will cancel out to finally have;

[tex]\dfrac{1}{C} = ({\dfrac{1}{C_1}+\dfrac{1}{C_2})[/tex]

This gives the equivalent capacitance of the combination.

Cesium has 37 isotopes. One of Cesium's most stable isotopes undergoes beta decay to form Barium-135. 135 Cs 55 is the correct isotopic notation for the original Cesium isotope before it decayed.

Beta decay is a radioactive decay in which a proton is converted into a neutron or vice versa inside the nucleus of the radioactive sample.

In beta decay, an electron is ejected which increases the atomic number.
