=IF(F3>=21,"Yes","No") This formula uses the IF function to compare the value in the Age column (F3) to the minimum age requirement (21). If the value in F3 is greater than or equal to 21, the function will return "Yes", otherwise it will return "No".

IF stands for "If Then" or "If-Else" and it is an important part of many programming languages. It is a type of conditional statement that allows you to set conditions and execute different sets of instructions depending on the outcome of the condition. For example, if an input is equal to a certain value, then a specific set of instructions will be executed. If the input is not equal to the value then a different set of instructions will be executed. IF statements are used to help create logic, control flow, and decision-making within a program.

The correct answer is 3.37 x 10-19 Joules.E= hc/lambda is the formula used to calculate the energy contained in a mole of photons, where h is the Planck constant, c is the speed of light, and is the wavelength of light.

The wavelengths of visible light split into the rainbow's hues as it passes through a prism because each color has a unique wavelength. Red has a wavelength of around 700 nanometers, whereas violet has a wavelength of about 380 nanometers. The wavelength and frequency of red light are 700 nm and 4.3*1014 Hz, respectively. Only a small portion of the entire electromagnetic spectrum is visible light. UV, X, and gamma rays are examples of electromagnetic waves with shorter wavelengths and higher frequency.

The maximum voltage across C1 is 10V in the circuit.

To calculate the maximum voltage across C1, we can use the following formula:

Vmax = Vp / √2

Where Vp is the peak voltage of the transformer output, and √2 is the square root of 2.

Given that the output of the transformer has an amplitude of 10V, we can calculate Vp as follows:

Vp = 10V * √2 = 14.14V

Therefore, the maximum voltage across C1 is:

Vmax = 14.14V / √2 = 10V

So the maximum voltage across C1 is 10V.

It is important to note that this calculation assumes mathematically ideal diodes, which means that there is no voltage drop across the diodes. In reality, there will be a small voltage drop across the diodes, which will slightly reduce the maximum voltage across C1.

Math is made more fascinating and enjoyable using Speed Maths (Vedic Maths). by assisting the child in quickly performing some improbable computations. By combining the correct amount of enjoyment, memory, skills, memory recall, and formula application, your child will become a superstar performer.

We can use the equations of motion in cylindrical coordinates to identify the parts of force that the slide applies to the youngster at the point t = 2 s. The boy's speed and acceleration can be determined as follows:

v = (dr/dt) e_r + (r dθ/dt) e_θ + (dz/dt) e_z

a = ((d² r)/(dt²) - r (dθ/dt)^2) e_r + (r d² θ/dt² + 2 (dr/dt) (dθ/dt)) e_θ + (d²z/dt²) e_z

where e_r, e_θ, and e_z are the unit vectors in the radial, tangential, and vertical directions, respectively.

At t = 2 s, we have:

r = 1.5 m

u = (0.7t) rad = 1.4 rad

z = (-0.5t) m = -1 m

Therefore,

dr/dt = 0

dθ/dt = 0.7 rad/s

dz/dt = -0.5 m/s

Substituting these values, we get:

v = (0) e_r + (1.05 m/s) e_θ + (-0.5 m/s) e_z

a = (-0.49 m/s²) e_r + (0) e_θ + (-0.5 m/s²) e_z

The components of force that the slide exerts on the boy can be found using Newton's second law:

F = m a

where m is the mass of the boy, which is 40 kg. Substituting this value, we get:

1. The equivalent capacitance between terminals a-c is 2.4 μF

2. The equivalent capacitance between terminals b-c is 6μF

3. The equivalent capacitance between terminals c-d is 12 μF

Capacitance is the ability for a device to store charge

Given that the capacitance bewteen terminals a-c = a-b + b-c

Now, the capacitance between terminals b-c are in parallel.

So, for capacitances in parallel, we add their capacitances to get the equvalent capacitance.

So, the equivalent capapcitance between b-c is C = 1 μF + 2μF + 3µF = 6μF

Now C is in series with the capapcitance between terminals a-b.

Since they are in series, their equivalent capapcitance C' is

1/C' = 1/4μF + 1/C

= 1/4μF + 1/6μF

= (3 + 2)/12 μF

1/C' = 5/12 μF

C' = 12/5 μF

= 2.4 μF

So, the equivalent capacitance between terminals a-c is 2.4 μF

To find the equivalent capacitance between terminals b-c, we see that the capacitance between terminals b-c are in parallel.

So, for capacitances in parallel, we add their capacitances to get the equvalent capacitance.

So, the equivalent capapcitance between b-c is C = 1 μF + 2μF + 3µF = 6μF

So, the equivalent capacitance between terminals b-c is 6μF

Since there is only one capacitor between terminals c-d, the equivalent capacitance is equal to the value of that capacitor which is 12 μF

So, the equivalent capacitance between terminals c-d is 12 μF
