When an object is placed beyond the focal length of a convex lens, the image formed is real and inverted.

When the object is at 2f, the image is formed at 2f on the opposite side, making it real and inverted.

When the object is placed beyond 2f, the image formed by a convex lens is real and inverted.

When the object is at infinity, the rays converge at the focal point, forming a real and inverted image.

A convex mirror always forms a virtual image that is upright and smaller than the object.

A plane mirror always forms a virtual and erect image, as the image appears behind the mirror at the same distance as the object.

An object at rest has no net force acting on it, according to Newton's first law.

The significant figures are 1, 2, 3, and the trailing zero counts.

The significant figures are 4, 5, and 6. Leading zeros are not counted.

Nyquist rate = 2 * f_max = 2 * 1000 Hz = 2000 Hz = 2 kHz.

Nyquist rate = 2 * f_max = 2 * 5 kHz = 10 kHz.

The Nyquist rate is the minimum sampling rate required to avoid aliasing, which is twice the highest frequency of the signal.

The Nyquist rate is the minimum sampling rate required to avoid aliasing, which is twice the maximum frequency of the signal.

The Nyquist rate is defined as twice the maximum frequency of the signal, which is the minimum sampling rate required to avoid aliasing.

The Nyquist rate is the minimum sampling rate required to avoid aliasing, which is twice the maximum frequency of the signal.

The orbital speed v of a satellite in a circular orbit is given by v = sqrt(GM/(R+h)^2), where G is the gravitational constant, M is the mass of the Earth, R is the radius of the Earth, and h is the height of the satellite above the Earth's surface.

The orbital speed of a satellite in low Earth orbit is approximately 7.9 km/s.

In single-slit diffraction, the central maximum corresponds to m = 0, which is the first bright fringe.

A NAND gate outputs 0 only when both inputs are 1. Therefore, if both inputs are high (1), the output is 0.

A NAND gate outputs false when both inputs are true.

A NOR gate outputs true when both inputs are false.

A NOR gate outputs 1 only when both inputs are 0. Therefore, if both inputs are low (0), the output is 1.

A NOT gate inverts the input. Therefore, NOT 0 = 1.

A NOT gate outputs false when the input is true.

An AND gate outputs 1 only when both inputs are 1. Since one input is 0, the output is 0.

An AND gate outputs 1 only when both inputs are high. Since both A and B are 0, the output is 0.

An AND gate outputs 1 only when both inputs are high. Since A = 0, the output is 0.

An OR gate outputs true if at least one input is true.

An OR gate outputs 0 only when both inputs are low. Therefore, the output is 0.

An XOR gate outputs false when both inputs are the same.
