Explanation

• The high resolution of the electron microscope is primarily due to the short wavelength of the electron beam.
• This shorter wavelength allows for higher resolution and the ability to visualize smaller structures.

Explanation

• Felis catus is the scientific name for the domestic cat.
• It belongs to the family Felidae and is a member of the order Carnivora.

Explanation

• The speed of sound is maximum in solids.
• Because the particles are closely packed, allowing for efficient transmission of vibrations.

Explanation

The pigment responsible for the red color inside a watermelon is lycopene.

Lycopene is also found in tomatoes and other red fruits and vegetables.

Explanation

Homologous pairs are chromosomes that are similar in shape, size, and genetic content, and contain the same genes in the same order.

They are pairs of chromosomes that are inherited one from each parent.

They are responsible for determining the traits and characteristics of an organism.

Explanation

When capacitors are connected in parallel, the total capacitance (Ct) increases, as the effective plate area and charge storage capacity increase.

The formula for total capacitance in parallel is: Ct = C1 + C2 + ... + Cn

In series connection, the total capacitance decreases, as the effective plate area and charge storage capacity decrease.

The formula for total capacitance in series is: 1/Ct = 1/C1 + 1/C2 + ... + 1/Cn

Explanation

The critical angle is the angle of incidence above which total internal reflection occurs.

It can be calculated using Snell's law:

n1 sin(θ1) = n2 sin(θ2)

where n1 = 1.33 (refractive index of water), θ1 = critical angle, n2 = 1 (refractive index of air), and θ2 = 90° (angle of refraction).

Rearranging the equation to solve for θ1, we get:

θ1 = arcsin(n2 / n1)

Substituting the values, we get:

θ1 = arcsin(1 / 1.33) ≈ 48.8°

So, the critical angle is approximately 48.8°.

Explanation

When white light passes through a prism, it is refracted, or bent, and split into its individual colors, a process known as dispersion.

The order of deviation is:

• Violet (most deviated)
• Blue
• Green
• Yellow
• Red (least deviated)

Explanation

• Television remote controllers use infrared (IR) waves to transmit commands to the TV.
• IR waves are a type of electromagnetic radiation with a frequency too low to be seen by the human eye.
• They are widely used in remote control applications, such as:
• TV remote controls
• Air conditioners
• DVD players
• Garage door openers
