Answer:
The period of oscillation is 1.33 sec.
Explanation:
Given that,
Mass = 275.0 g
Suppose value of spring constant is 6.2 N/m.
We need to calculate the angular frequency
Using formula of angular frequency
Where, m = mass
k = spring constant
Put the value into the formula
We need to calculate the period of oscillation,
Using formula of time period
Put the value into the formula
Hence, The period of oscillation is 1.33 sec.
Explanation:
One of the takeaways of the General Theory of Relativity (GTR) was that the light can be curved because of the gravity of a massive object. Einstein had proposed the idea of <em>space-time</em> fabric. Every object having mass will create depression in this fabric. Heavier the object, bigger the depression. Thus when light will pass near a heavy object lets say our Sun, it will deflect. He also gave mathematical formula to calculate the deflection.
The same was proved during the Total Solar Eclipse of 29 May 1919. Two scientists named Arthur Eddington and Frank Dyson conducted an experiment. In this eclipse the Sun was to be in front of Hyades in Taurus constellation. They took the measurement of stars of Hyades visible during the eclipse and then compared them with the actual readings. The deflection was clearly visible and the amount of deflection was very close to the values predicted by General Theory of Relativity. Thus they proved the theory right.
The net force simply the sum of two forces:
Negative and positive are assigned to those forces to show direction because it is a vector.
So, given that left is negative and right is positive;
<em>a)</em>
2.30N - .800N = 1.50 N
Given the equation F = ma, where m= 0.125 (mass) and F = 1.50 (force), we can solve for a (acceleration).
<em>b)</em>
1.50 N = (0.125 kg) a
a = 12.0 ms^-2
The expanded-function dental assistant (EFDA) can play a
major role in the fabrication and temporary cementation of a provisional crown
or bridge. It is the dentist’s and the EFDA’s responsibility to remain current
with the new provisional materials and techniques that are available. It is
essential that a provisional crown or bridge remain cemented while the fixed
prosthesis is being prepared and delivered to the dental office. When the
patient returns for final cementation of a fixed crown or bridge, the
provisional should be cautiously removed without causing any fracture or harm,
just in case it will need to be recemented if the final prostheses needs to be
sent back to the lab for adjustments and remake.
I believe so, yes.
