A 16.2 cm diameter circular loop of wire is in a 1.44 T magnetic field. It is removed from the field in 0.140 s. What is the average induced emf?
If the current in a 100 mH coil changes steadily from

The calculated value is AO=3.2sec.

The limit of average velocity as elapsed time approaches zero, or the derivative of x with respect to t: v (t) = d d t x (t), is the instantaneous velocity of an object. v (t) equals d d t x (t). Instantaneous velocity is a vector having a dimension of length per time, similar to average velocity.

In contrast to instantaneous velocity, which is determined by the slope of the tangent line, average velocity is defined as the change in position (or displacement) during the course of transit.

So, we obtain

cosθ= 5/4

= 4AO

So, we obtain AO=3.2sec.

Answer:

Derived quantities depend on two or more physical quantity.

Answer:

v = 6t² + t + 2, s = 2t³ + ½ t² + 2t

59 m/s, 64.5 m

Explanation:

a = 12t + 1

v = ∫ a dt

v = 6t² + t + C

At t = 0, v = 2.

2 = 6(0)² + (0) + C

2 = C

Therefore, v = 6t² + t + 2.

s = ∫ v dt

s = 2t³ + ½ t² + 2t + C

At t = 0, s = 0.

0 = 2(0)³ + ½ (0)² + 2(0) + C

0 = C

Therefore, s = 2t³ + ½ t² + 2t.

At t = 3:

v = 6(3)² + (3) + 2 = 59

s = 2(3)³ + ½ (3)² + 2(3) = 64.5

The human vocal apparatus is an incredibly complex and efficient machine. The production of speech sounds begins with the diaphragm, a large, flat muscle located at the bottom of the lungs. When the diaphragm contracts, it increases the volume of the thoracic cavity and forces air into the lungs. The air then passes through the larynx, or voice box, which contains the vocal cords. The vocal cords are two thin bands of tissue that vibrate when air passes through them. The pitch of the resulting sound is determined by the tension of the vocal cords.

The sound of the vibrating vocal cords is then amplified by the resonating cavities of the head and mouth. The shape of the mouth cavity plays a significant role in the production of speech sounds. For example, the placement of the tongue, teeth, and lips all contribute to the creation of different vowel sounds. The hard and soft palate, along with the tongue, also help to create different consonant sounds.

Answer:

the final velocity of the car after 6 seconds of acceleration is 30 m/s.

Explanation:

The final velocity of the car can be found using the kinematic equation:

v = u + at

where u is the initial velocity (which is zero since the car starts from rest), a is the acceleration (which is 5 m/s^2), t is the time elapsed (which is 6 seconds).

Substituting the given values, we get:

v = 0 + 5 x 6

The best estimate of the magnitude of the box's acceleration rounded to two significant digits is 11 m/s².

Mass of the box = m = 2 Kg

Coefficient of static friction between the box and table = μ = 0.40

Coefficient of kinetic friction between the box and table = μ' = 0.20

Horizontal force = f = 25 N

The kinetic frictional force = f' =

= f' = μ' X f

= f' = μ' X m X g

= f' = 0.20 X 2 X 9.81

= f' = 3.924 N

By applying the Newton's second law of motion, the total or net force is given as =

= ∑Fx = Applied horizontal force - kinetic frictional force = m X a

= Applied horizontal force - kinetic frictional force = m X a

= ( f - f' )  = ma

Acceleration of the box = a =

= a = (25 - 3,924) / 2

= a = 10.538 m/s²

= a ≈ 11 m/s²

So, Wavelength = 2*.65=1.3m, frequency=248Hz

Speed=wavelength*frequency=1.3*248=322.4 m/s.

The wavelength, or spatial period, of a periodic wave in physics refers to the length over which the wave's structure repeats. It is the separation between neighbouring wave points that correspond to the same phase, such as two adjacent crests, troughs, or zero crossings. It is a property of both travelling waves and standing waves as well as other spatial wave patterns. The spatial frequency is the wavelength's reciprocal. The Greek letter lambda (), which represents wavelength, is frequently used. When describing modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids, the term wavelength is also occasionally used.

The correct position that the fuse should be to ensure safety from the image is b.

A fuse is a type of electrical safety device used to guard against excessive current flow in electrical circuits. When there is a surge or overload of power, its main purpose is to interrupt the electrical current and break the circuit.

The fuse wire or element inside the fuse warms up due to resistance when the current flowing through a circuit exceeds the rated limit of the fuse. This opens the circuit and destroys the electrical connection by causing the fuse wire to melt or burst. The fuse does this to stop an excessive amount of current from passing through the circuit, which may cause overheating, harm to electrical equipment, or even provide a fire risk.

Type Ia supernova is approximately 72.38 million parsecs away in the distant galaxy.

To determine the distance to a Type Ia supernova in a distant galaxy with an apparent magnitude of 10, we will use the distance modulus formula. The distance modulus formula relates the apparent magnitude (m), absolute magnitude (M), and distance (d) in parsecs. The formula is:

m - M = 5 * log10(d) - 5

For a Type Ia supernova, the absolute magnitude is roughly -19.3. Now, we have the values for m and M, and we can solve for d:

10 - (-19.3) = 5 * log10(d) - 5

Next, isolate log10(d):

29.3 = 5 * log10(d) - 5
34.3 = 5 * log10(d)

Now, divide by 5:

6.86 = log10(d)

To find d, raise 10 to the power of 6.86:

d = 10^6.86

Finally, calculate the distance:

d ≈ 72.38 million parsecs

So, the Type Ia supernova is approximately 72.38 million parsecs away in the distant galaxy.

Answer:

Ohm's law verifies that current directly varies with voltage, when resistance increases, current current decreases.

When temperature increases, the electrons gain more average kinetic energy increases and current increases as well.

In the same situation, resistance also increases because atoms of a component vibrate at higher amplitudes about their mean positions hence reducing the free path of electrons. This increases resistance, hence ohms law violated or disobeyed.

This generates the temperature coefficient of resistance

In Rutherford's famous set of experiments, the fact that some alpha particles were deflected at large angles indicated that the atom contains a dense, positively charged nucleus.

Rutherford conducted experiments where he bombarded a thin gold foil with alpha particles. According to the prevailing model at the time, the Thomson model, it was believed that the positive charge in an atom was spread uniformly throughout the atom, much like plum pudding.

However, Rutherford's observations revealed that some alpha particles experienced significant deflections and even bounced back at large angles. This unexpected result could not be explained by the Thomson model.

Rutherford proposed a new atomic model known as the nuclear model, suggesting that the atom consists of a tiny, dense, positively charged nucleus at the center and the majority of the atom is empty space. This explained the deflection of alpha particles, as they were repelled or deflected by the positive charge concentrated in the nucleus.

The deflection of alpha particles at large angles indicated the presence of a compact and positively charged nucleus within the atom, leading to a fundamental revision of the understanding of atomic structure.
