Explanation

In this context, λ refers to Planck's constant, which is a fundamental constant in quantum mechanics denoted by h.

It relates the energy of a photon to the frequency of its electromagnetic wave.

Explanation

The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.

Explanation

The induced electromotive force (emf) ($varepsilon$) in a moving conductor in a magnetic field can be calculated using the formula:

$$\epsilon =B\cdot L\cdot v$$

Where:

• $B$ is the magnetic field strength (in teslas),
• $L$ is the length of the conductor (in meters),
• $v$ is the velocity of the conductor (in meters per second).

Given:

• $B = 0.6 , text{T}$
• $L = 1 , text{m}$
• $v = 20 , text{m/s}$

Substituting the values into the formula:

$$\epsilon =0.6\text{T}\cdot 1\text{m}\cdot 20\text{m/s}=12\text{V}$$

Thus, the value of the induced emf is 12 V.

Explanation

Angstrom , unit of length used chiefly in measuring wavelengths of light, equal to 10−10 metre, or 0.1 nanometer.

It is named for the 19th-century Swedish physicist Anders Jonas Ångström.

Explanation

Oxygen in water (H₂O) has 2 bonding and 2 lone pairs, totaling 4 electron pairs.

Explanation

The sarcoplasm surrounds the muscle fiber of the skeletal muscle.

It is the cytoplasm of muscle cells.

Explanation

After an enzyme-catalyzed reaction, the enzyme is used for another reaction as enzymes are not consumed in the process.

Explanation

Explanation

Electricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber.
