Answer:
66m/s
Explanation:
because 10 meters/per second is going to be 22 mph/35 km, and 20m/s is 44 mph/70 km and in 3 seconds it would boost its mph/km(m/s) to 66 only because from 22 mph to 44 mph is 22 but 44/22 = 22, however you have top multiply that by 3 seconds which will coem out to 66 m/s, mph, km.
Answer:
Explanation:
= Mass of Bonzo
= Mass of Ender
= Initial Velocity of Bonzo = 2.2 m/s
= Initial Velocity of Ender = -2.6 m/s
From conservation of linear momentum
Pitch is directly related to the frequency of the sound. In this item, we are given that the frequency of the sound is higher compared to those which are audible to the human being's ears. The pitch therefore of the dog's whistle is high.
On the other hand, the frequency and the wavelength of a certain wave are inversely proportional. This means that the high frequency wave will have a short wavelength.
Hence, the answer to this item would have to be "high pitch with a short wavelength"
The answer to this item is the second option.
Answer:
As per the fossil fuel records, magnetic field reversal does not impact living beings. It will take almost a century for the poles to complete the shift. Meanwhile, the earth is left with almost zero magnetic field.
