For fundamental frequency of a string to occur, the length of the string has to be half the wavelength. That is,
1/2y = L, where L = length of the string, y = wavelength.
Therefore,
y = 2L = 2*0.75 =1.5 m
Additionally,
y = v/f Where v = wave speed, and f = ferquncy
Then,
v = y*f = 1.5*220 = 330 m/s
The overall arrangements of the atoms produce crystals
The answer is False because HIV spreads through contact between HIV-infected blood or blood-contaminated body fluids and broken skin, wounds, or mucous membranes. Deep, open-mouth kissing if both partners have sores or bleeding gums and blood from the HIV-positive partner enters the HIV-negative partner's bloodstream.
The objects that look black are all tied for first place.
Answer:
The second engine with no cars will accelerate more.
Explanation:
Since the engines are identical so they hacve the same mass. The first engine has 10 cars attached which adds more mass to it whereas second engine has no cars attached.
Therefore second engine is lighter in mass than the first one.
<u>We know from the Newton's second law of motion:</u>


Now, according to question both the engines exert same force for moving.
We see that :

So more is the mass, lesser is the acceleration, hence the second engine with no cars will accelerate more.
