The greater the amplitude of a wave, the greater its D) energy

Explanation:

- The amplitude of a wave is the maximum displacement of the wave with respect to the equilibrium position. It is generally indicated with A.

The energy of a wave is proportional to the square of its amplitude:

E=\propto A^2

Therefore, we immediately see that option D) is the correct one: the greater  amplitude of the wave, the greater its energy.

The other quantities of a wave are:

- Frequency: it is the number of complete cycles of the wave per second

- Wavelength: it is the distance between two crests of the wave

- Speed: the speed of a wave is calculated using the equation

v=f \lambda

where f is the frequency and \lambda is the wavelength.

After landing on an unexplored Klingon planet, Spock tests for the direction of the magnetic field by firing a beam of electrons
BARSIC [14]

Answer:

Magnetic field is in south west direction .

Explanation:

Let us represent various direction by  i , j, k . i representing east , j representing north and k representing vertically upward direction .

magnetic field is represented vectorially as follows

B = B₀ ( - i - j )

In the first case velocity of electron

v = v k

Force = q ( v x B )

= -e [ vk x B₀ ( - i - j ) ]

= evB₀ ( j -i )

Direction of force is north -west .

In the second case velocity of electron

v = vj

Force = -e [ vj x B₀ ( - i - j ) ]

= - evB₀ k

force is downward

In the third case, velocity of electron

v = v( -j +i )

Force = -e [ v( -j +i ) x B₀ ( - i - j ) ]

= 2 evB₀ k

Force is upward.
