Explanation:
to test my hypothesis i put a plant in a room at room temp and repeat how i grew it,and observe what went wrong. hope this helps=)
Answer:
The simple harmonic wave function is
Explanation:
Generally a sine wave is mathematically represented as
Here A is the amplitude which is mathematically represented as
substituting 0.25 m for Z we have that
k is the wave number which is mathematically represented as
substituting 1.1 m for (wavelength ) we have
=>
w is the angular frequency which is mathematically represented as
Here T is the period which is mathematically represented as
substituting 13 wave pass for n and for t
So
So
Answer:
E) V=(m/M)v
Explanation:
Given that
Mass of the small ball = m
Initial velocity of the small ball = v
Mass of the larger ball = m
Initial velocity of the larger ball = 0
After the collision
The velocity of the small ball = 0
The velocity of the larger ball = V
There is no any external force that is why linear momentum will be conserve.
From linear momentum conservation
Pi=Pf
m v + M x 0 = m x 0 + M V
m v +0 = 0 + M V
Therefore the answer will be E.
E) V=(m/M)v
Ionic bonds with electrostatic attractions
Answer:
Part a)
Part B)
percentage increase is
%
Explanation:
Part a)
As we know that the beat frequency is
after increasing the tension the beat frequency is decreased and hence the tension in string B will increase
So we have
Part B)
percentage increase in the tension of the string will be given as
now we have
so we have
so we have
percentage increase is
