Answer: 300 m/s
Explanation:
Given that:
length of water wave (λ) = 10 metres
Frequency of water wave (F) = 30 Hertz
Velocity of water wave (V) = ?
The velocity of a wave is the distance covered by the wave in one second. It is measured in metre per second, and represented by the symbol V. It is related to frequency and wave length by the formula: V = F λ
V = 30 Hertz x 10 metres
V = 300 m/s
Thus, the velocity of the water wave is 300 m/s
A deciliter is 1/10 of a liter, so 82 deciliters is 8.2 liters<span>.</span>
A horizontal line on a distance-time graph indicates that an object is stationary.
dharna is said to be concentration.. it is true
<span>While
modern humans first evolved approximately 200,000 years ago,
the age of
the Earth, the Sun, and the rest of the solar system is believed
to be approximately 4.6 billion years.
That makes the Earth, the Sun, and the rest of the solar system
something like 23 thousand times as old as the human species !
