Answer:
The water makes a cloud when the warm moist air meets the colder air. This demonstrates the formation of what we know as "clouds". Then precipitation happens when the clouds gets to full of water droplets. Finally, accumulation happens when the water forms puddles and goes back to the lakes and streams.
Find the equivalent resistance of this circuit.
Step-by-step explanation :
Here we just need to see the resistors which are connected in series combination. (Remember that you need not to use the potential difference in this question because we aren't asked to calculate the current).
As we know that,
Rs = R1 + R2 ... Rn>> Rs = 50 + 100
>> Rs = 150Ω
Therefore,
Resistance in series combination is of 150Ω.Water flows into a vertical cylindrical tank at the rate of 24 cubic ft per minute. If the radius of the tank is 4 ft, how fast is the surface rising?
per min= 24 cubic ft
radius= 4 ft
to find:how fast the surface rises.
solution:[tex]area = \pi {r}^{2} [/tex]
[tex]a = \pi \times {4}^{2} [/tex]
[tex]a = 50.24 \: {ft}^{2} [/tex]
[tex]v = 24 \: {ft}^{3} [/tex]
[tex] = \frac{24}{50.24} [/tex]
[tex] = 0.48[/tex]
therefore, the rising in the surface area is 0.48 feet per minute.
24 / 50.24 = 0.48 feet per minute
so the answer to your question is 0.48 feet per minute.

What is the energy of a photon with a wavelength of 245 nm
The energy of a photon with a wavelength of 245 nm will be 8.08 ×10⁻¹⁹ J. De Broglie relation is used to find out the energy.
What is wavelength?The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The relationship between the wave's wavelength,energy is;
[tex]\rm E = \frac{hc }{\lambda} \\\\ \rm E = \frac{6.6 \times 10^{-34} \times 3 \times 10^8}{245 \times 10^{-9}} \\\\ \rm E=8.08 \times 10^{-19}\ J[/tex]
Hence, the energy of a photon will be 8.08 ×10⁻¹⁹ J.

A 30 ohm resistor and a 20 ohm resistor are
connected in series with a 100 volt battery. What is
the electrical current that would pass through the
30 ohm resistor?
The current that would pass through the 30 ohms resistor is 2 A.
What is electric current?Electric current is the rate of flow of electric charge round a conductor.
To calculate the electric current that would pass through the 30 ohms resistor, we use the formula below
Formula:
I = V/Rt........... Equation 1Where:
I = Electric current passing through the 30 ohms resistorV = VoltageRt = Total or effective resistance of the resistors.From the question,
Given:
V = 100 voltsRt = (30+20) ohms (since both resistors are connected in series)Rt = 50 ohmsSubstitute these values into equation 1

What is the worst type of schizophrenia?
Schizophrenia called hebephrenic is the most serious of all and affects more young individuals, between 15 and 25 years of age. The disorder is marked by symptoms such as disturbed affect, irresponsible and unpredictable behavior, disorganized thinking, and incoherent speech.
Undifferentiated schizophrenia — this is the case for patients who may develop some of the characteristics of the other types, but do not fit neatly into any of them.

a ball on a string is swung overhead in a horizontal circle with a radius of 0.66 m. what speed (in m/s) does the ball need to maintain for there to be a centripetal acceleration of 23 m/s2?
Answer:
The ball is moving in a horizontal circle.
The force acting towards the center of the circle is
F = M a = M * V^2 / R
a = V^2 / R simplifying equation
V = (a / R)^1/2 = (23 / .66)^1/2 = 5.90 m/s

What is the relation between electric intensity dn flux
The relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.
What is the relation between electric intensity and flux?The electric field is the field, which is surrounded by the electric charged. The electric field is the electric force per unit charge.
The intensity of this electric field is the number of electric field lines which are pass perpendicular to the unit element of fixed area.The flux of this electric field is the number of electric field lines which are pass normally to the fixed area.The electric flux can be given as,
[tex]d\phi =\vec E \;dA\cos \theta[/tex]
When angle is zero,
[tex]d\phi =\vec E \;dA\times1\\d\phi =\vec E \;dA[/tex]
Thus, the total flux is,
[tex]\phi=\oint_{}^{}\vec E.d\vec A[/tex]
Thus, the relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.

What is Snell's law?It states that the ratio of sine of angle of incidence and angle of refraction is equal to the refractive index of second medium to the first medium.
sini/sinr = n₁/n₂
Given the angle of incidence i = 25 degrees, angle of refraction r =40 degrees, refractive index of air n₁ =1, then refractive index of medium X is

A 4.4 nC charge exerts a repulsive force of 36 mN on a second charge which is located
a distance of 0.70 m away from it. What is the charge (magnitude and sign) of the
second charge?
The magnitude and sign of the second charge will be + 8.6241×10⁻¹⁹ C. The principal of the Columb's law is used in the given problem.
What is Columb's law?The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Charges that are similar repel each other, whereas charges that are diametrically opposed attract each other.
They will repel, moving in opposite directions at the same speed. Because the magnitude and nature of the charge are the same.
The given data in the problem is;
q₁ is the charge 1 = 4.4 nC = 4.4 ×10⁻⁹ C
F is the repulsive force = 36 mN =36 ×10⁶ N
d is the distance = 0.70 m
The Coulomb force is found as;
[tex]\rm F = \frac{Kq_1q_2}{r^2}\\\\\ \rm 36\times 10^6 = \frac{9 \times 10^9 }{(0.7)^2} \times 4.4 \times 10^{-9} \times q_2\\\\\ q_2 = 8.6241 \times 10^{-19 } \ C[/tex]
Hence, the magnitude and sign of the second charge will be + 8.6241×10⁻¹⁹ C.
