Answer:
a) m_v = m_s (()² - 1) , b) m_v = 1.07 10⁻¹⁴ g
Explanation:
a) The angular velocity of a simple harmonic motion is
w² = k / m
where k is the spring constant and m is the mass of the oscillator
let's apply this expression to our case,
silicon only
w₉² =
k = w₀² m_s
silicon with virus
w² =
k = w² (m_v + m_s)
in the two expressions the constant k is the same and q as the one property of the silicon bar, let us equal
w₀² m_s = w² (m_v + m_s)
m_v = ()² m_s - m_s
m_v = m_s (()² - 1)
b) let's calculate
m_v = 2.13 10⁻¹⁶ [()² - 1)]
m_v = 1.07 10⁻¹⁴ g
Answer:
d. displacement
Explanation:
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Sublimation is a type of printing that involves heat and a special type of printer. You use specialized ink to print onto transfer paper then place the paper on the item you are sublimating and then you heat press it for the allotted time.
Ashley ran with a speed of 12 feet per second.
Speed is measured as the ratio of the distance travelled to the time it took to cover that distance.
Since speed simply has a magnitude and no direction, it is a scalar quantity.
The formula for the speed of an object/body is given as-
where, d is the distance travelled by the body/object and t is the time taken by the body/object to cover the distance
Ashley has covered a distance of 264 feet and the time taken to cover this distance is 22 seconds.
Now, Ashley’s speed can be calculated by dividing the distance of 264 feet to the time taken by Ashley cover this distance, i.e.
Thus, the speed with which Ashley ran was 12 feet per second.

Answer:
Explanation:
We need to find the energy for an electron to jump from n = 1 to n = 4.
The energy in transition from 1 state to another is given by :
The difference in energy for n = 1 to n = 4 is:
So, the required energy is equal to .
