Power P = V^2/R = 24^2/8 = 576/8 = 72 W.

Total resistance R = 3Ω + 6Ω = 9Ω. Current I = V/R = 9V/9Ω = 1A.

Total resistance R_total = 3Ω + 6Ω = 9Ω. Current I = V/R_total = 9V/9Ω = 1A. Voltage across 6Ω = I * R = 1A * 6Ω = 6V.

Using Ohm's Law, R = V/I = 24V / 6A = 4Ω.

In a circuit with an inductor, the current increases gradually due to the inductor's opposition to changes in current.

Using Ohm's Law, V = I * R = 5A * 10Ω = 50V.

Using Ohm's Law, V = I * R = 5A * 10Ω = 50V.

According to Ohm's law, I = V/R. If R is doubled, I will be halved.

Using Ohm's Law, R = V / I = 24V / 3A = 8Ω.

According to Ohm's law, if V is tripled, I will also triple.

According to the first law of thermodynamics, if the internal energy increases, it implies that either work is done on the system or heat is added to the system.

According to the first law of thermodynamics, if the internal energy increases, it implies that heat is added to the system and/or work is done on the system.

The focal length of a concave lens is always negative, as it diverges light rays.

The focal length of a concave lens is considered negative as it diverges light rays.

The focal length of a concave lens is negative, indicating that it diverges light rays.

Decreasing the slit width increases the diffraction angle, causing the central maximum to become wider.

Power (P) of a lens is given by P = 1/f (in meters). Here, f = 15 cm = 0.15 m, so P = 1/0.15 = +6.67 D.

Increasing the slit separation d decreases the fringe width, causing the fringes to move closer together.

The distance between the fringes decreases as fringe width β = λD/d; increasing d reduces β.

Using polychromatic light results in overlapping patterns of different wavelengths, causing the overall pattern to become broader.

Moving the screen further away increases the fringe separation, as fringe width β = λD/d; increasing D increases β.

In a fluid at rest, the pressure at a point depends on the depth of the fluid above that point.

In a fluid at rest, the pressure at a point depends on the height of the fluid column above it, as described by hydrostatic pressure.

Laminar flow refers to fluid motion in parallel layers with no disruption between them.

In a fluid, pressure increases with depth due to the weight of the fluid above.

Hydrostatic head is the height of a fluid column that exerts a certain pressure, calculated as pressure divided by the density and gravitational acceleration.

Surface tension is the property of a fluid that causes its surface to behave like a stretched elastic membrane.

Systematic errors lead to biased results, consistently deviating from the true value.

Systematic errors indicate a consistent bias in measurements.

Systematic errors can be corrected by subtracting the known error from the measured value.
