In several of the questions you've posted during the past day, we've already said that a wave with larger amplitude carries more energy. That idea is easy to apply to this question.

Answer: ' A wave with a large amplitude".

Explanation :

A rogue wave is a random monstrous wave that occurs unexpectedly in the ocean.

The wave having higher amplitude will transmit more energy because the energy of the wave depends directly on the amplitude.

The amplitude of a wave is measured from the rest position to the top of a crest or from the rest position to the bottom of the trough. It is measured in meters.

So, the correct option is (B) ' A wave with a large amplitude".

Answer:

Force / mass

Explanation:

Divide mass on both sides to get acceleration by itself leaving you with mass below force hence divide force by mass

How fast is a ball going when it hits the ground after being dropped from a

Umnica [9.8K]

Answer:

Option D.

Explanation:

Data:

Height (h) = 9 m
Gravity (g) = 9.8 m/s²
Velocity Final (Vf) = ?

Use formula:

Vf² = 2 * g * h

Replace:

Vf² = 2 * 9.8 m/s² * 9 m

Multiply gravity with height:

Vf² = 2 * 88.2

Multiply:

Vf² = 176.4

Solve the square root:

Vf = 13.3

How fast is the ball going?

The speed is going at a speed of <u>13.3 meters per second.</u>

The magnitude of the velocity vector of the car is ∣∣v→∣∣ = 78 ft/s. If the vector v→ forms an angle θ = 0.09 rad with the horiz

kotegsom [21]

Answer:

$\vec{v} = (77.68~{\rm ft/s})\^i + (7.01~{\rm ft/s})\^j$

Explanation:

The x- and y- components of the velocity vector can be written as following:

$\vec{v}_x = ||\vec{v}||\cos(\theta)\^i$

$\vec{v}_y = ||\vec{v}||\sin(\theta)\^j$

Since the angle θ and the magnitude of the velocity is given, the vector representation can be written as follows:

$\vec{v} = 78\cos(0.09)\^i + 78\sin(0.09)\^j\\\vec{v} = (77.68~{\rm ft/s})\^i + (7.01~{\rm ft/s})\^j$

Answer:

D. 3.0 × 10^-6 m

Explanation:

Wavelength is found by dividing the speed of light by the frequency:

λ = c/f = (3·10^8 m/s)/(1.0·10^14 Hz) = 3.0·10^-6 m
