Answer:
False
Explanation:
Think about every warning on electrical products, which is 'DO NOT KEEP NEAR WATER'
Answer:
As we know that science is based upon logic. So the scientific theories have a logical reasoning behind them. So considering that in mind, scientific hypothesis include the motion of sailing rocks by animals, wind, flowing water, magnetic field, humans and gravity. The motion of the rocks by ghosts, God and magic are not scientific theories as we can not prove them logicaly.

Answer: The mass of the jet is 26,225
Explanation: Convert 250km to m =250,000
1 hour = 3600
Velocity = 69.4 m/s
a= change in v/change in t
69.4/2 = 34.7
9.10×105 / 34.7 = 26,225 KG
Yw and pls mark me as brainiest
Answer:
See Explanation
Explanation:
a) We know that;
v = λf
Where;
λ = wavelength of the wave
f = frequency of the wave
v = velocity of the wave
So;
T = 2 * 2.10 s = 4.2 s
Hence f = 1/4.2 s
f = 0.24 Hz
The wavelength = 6.5 m
Hence;
v = 6.5 m * 0.24 Hz
v = 1.56 m/s
b)The amplitude of the wave is;
A = 0.600 m/2 = 0.300 m
c) Since the wave speed does not depend on the amplitude of the wave then the answer in (a) above remains the same
Where d = 0.30 m
A = 0.30 m/2 = 0.15 m
