Answer:
Momentum is conserved.
All of the others are not conserved because of heat loss caused by deformation, etc.
Answer:
W = 1.49 10⁻¹¹ kg
Explanation:
For this problem, let's use Newton's equation of equilibrium
F - W = 0
F = W (1)
Strength can be found from the definition of pressure
P = F / A
F = P A
The radiation pressure for a reflective surface is
P = 2 I / c)
We substitute in equation 1
2 I / c A = W
The intensity is defined by the ratio of the power between the area
I = P / A
P = I A
We substitute
2 P / c = W
W = 2 2.24 10-3 / 3 108
W = 1.49 10⁻¹¹ kg
Answer:
a = -04978 m / s²
Explanation:
For this exercise we can use the kinematics equations, as the initial speed, distance and time indicate, we can use
x = x₀ + v₀ t + 1 /2 a t²
½ a t² = x-x₀ - v₀ t
a = (x-x₀ - v₀ t) 2 / t²
let's reduce the magnitudes to the SI system
x₀ = 1000 mm = 1 m
x = 5000mm = 5m
let's calculate
a = (5 - 1 - 15 60) 2/60²
a = -04978 m / s²
negative sign indicates that braking is related
Swept-frequency pulses have found use in a variety of fields, including spectroscopic methods where effective spin control is necessary.
To find more, we have to study about the spectroscopic methods.
<h3>
What is homonuclear decoupling and broadband excitation?</h3>
- A thorough understanding of the evolution of spin systems during these pulses is crucial for many of these applications since it not only helps to describe how procedures work but also makes new methodologies possible.
- Broadband inversion, refocusing, and excitation employing these pulses are some of the most popular applications in NMR, ESR, MRI, and in vivo MRS in magnetic resonance spectroscopy.
- A generic expression for chirped pulses will be presented in this study, along with numerical methods for calculating the spin dynamics during chirped pulses using solutions along with extensive examples.
Thus, we can conclude that, the swept-frequency pulses have found use in a variety of fields, including spectroscopic methods where effective spin control is necessary.
