Wanswer is ''sedimentary'' rocks
Answer:
Explanation:
The figure is not provided and we don't know the force applied to the books.
Therefore, here we are going to assume the force applied is 3 N:
F = 3 N
We can find the acceleration of the stack of books by using Newton's second law of motion, which states that the net force on an object is equal to the product between its mass and its acceleration:
where
F is the force
m is the mass
a is the acceleration
In this problem we have
m = 1.5 kg is the mass of the books
Therefore, the acceleration is:
Answer:
a. 0.18Hz
b. 0.56m/s
Explanation:
From the question we can deduct the following parameters
The wavelength, λ is define as the distance between two successful crest or trough and from the question we conclude that wavelength is 3.17m.
Also the period of the wave T can be computed as
T=22.6/4
T=5.65secs.
a. To compute the frequency, recall that frequency, F=1/period.
Hence,
F=1/5.65
F=0.18Hz
b. Next we compute the wave speed.
Wave speed=frequency *wavelength
Wave speed =0.18*3.17
Wave speed =0.56m/s
Refract mean to break. the quarter would look broken. hope this helps
Answer: B.)He should wire each room in parallel with the next
Explanation:
The voltage across each component connected in parallel is same. When a component in a parallel circuit, it does not effect working of other components. On the other hand, when a component in series circuit is switched off, whole circuit breaks and other components stop working as well. Thus, in order to create a plan that will allow the homeowners to turn off lights in one room without turning the light off the lights in another, he should wire each room in parallel with the next. Option B is correct.
