A longitudinal wave is observed. Exactly 6 crests are observed

1 answer:

3 0

The speed of the wave is 1.58 meters per second (or 1.584 if you don’t round it).
You multiply wavelength by frequency to get the speed of a wave.
2.4 times 0.66 = 1.548 meters per second.

If you didn’t have the frequency before hand, you would just divide the 6 crests by the 9.1 seconds.

As a rocket is launched, the net force on it stays constant even though the mass decreases (in the form of rocket fuel being con

Rus_ich [418]

Answer:

'acceleration will increase.'

Explanation:

We know that force on the rocket is given as follows

$F=m\dfrac{dv}{dt}$

m=mass

v=velocity

t=time

F=force

$F=m\dfrac{dv}{dt}$

F= m a

a=acceleration

$a=\dfrac{F}{m}$

If the mass m decreases then the acceleration of the rocket will increase.

Therefore we can say that if the mass m decreases then the acceleration a will increases to maintain the constant force F.

The answer will be 'acceleration will increase.'

Plz help!! If the mass of an object is 44 kilograms and its velocity is 10 meters per second east, how much Kinetic Energy does

stellarik [79]

KE = 1/2 * m * v^2
m = 44
v = 10

KE = 1/2 * 44 * (10)^2
KE = 22 * 100 = 2200 J or B

In terms of instrument sensitivity, explain why he choice of wavelength on the colorimeter is important

elena55 [62]

Colorimeters function by passing colored light through a specific optical filter. The choice of wavelength on the colorimeter is important in terms of instrument sensitivity since the device gives the most sensitivity which can be used as a test factor in determining the lower detection limit.
