Answer:
<h3>0.445</h3>
Explanation:
In friction, the coefficient of friction formula is expressed as;
![\mu = \frac{F_f}{R}](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%5Cfrac%7BF_f%7D%7BR%7D)
Ff is the frictional force = Wsinθ
R is the reaction = Wcosθ
Substitute inti the equation;
![\mu = \frac{Wsin \theta}{W cos\theta} \\\mu = \frac{sin \theta}{cos\theta} \\\mu = tan \theta](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%5Cfrac%7BWsin%20%5Ctheta%7D%7BW%20cos%5Ctheta%7D%20%5C%5C%5Cmu%20%3D%20%5Cfrac%7Bsin%20%5Ctheta%7D%7Bcos%5Ctheta%7D%20%5C%5C%5Cmu%20%3D%20tan%20%5Ctheta)
Given
θ = 24°
![\mu = tan 24^0\\\mu = 0.445\\](https://tex.z-dn.net/?f=%5Cmu%20%3D%20tan%2024%5E0%5C%5C%5Cmu%20%3D%200.445%5C%5C)
Hence the coefficient of kinetic friction between the box and the ramp is 0.445
Answer:
The correct answer is - A matter that has an ordered arrangement of atoms, molecules, or ions.
Explanation:
In physics, a crystal is a type of solid matter in which a highly arranged molecule or atoms present to form a lattice that extended in all directions. It is a lightweight clear solid which is normally is colorless.
It can be cubic, hexagonal, triclinic, monoclinic, orthorhombic, tetragonal, and trigonal that are ordered arrangments. Its internal symmetry is visible to its surface.

Answer:
54.67 N
Explanation:
The total energy produced is the product of power and time duration:
E = Pt = 82 * 1 = 82 J
Which is converted from work, product of forced extended over a displacement
W = E = Fs = F*1.5 = 82
F = 82 / 1.5 = 54.67 N
So the magnitude of the force exerting on the handle is 54.67 N
Time period remains the same in both the experiment as change in amplitude does not affect time period.
What are the factors on which time period depends in SHM?
Time period is given by:
![T=2\pi \sqrt{\frac{m}{k} }](https://tex.z-dn.net/?f=T%3D2%5Cpi%20%5Csqrt%7B%5Cfrac%7Bm%7D%7Bk%7D%20%7D)
where,
T = time period
m = mass
k = spring constant
In a straightforward harmonic motion, we see from the preceding formula that the time period depends only on the object's mass and spring constant (SHM). The time period will adjust to any variations in the object's mass or the spring constant.
What is Spring Constant?
A spring's "spring constant" is a property that quantifies the relationship between the force acting on the spring and the displacement it produces. In other words, it characterises a spring's stiffness and the extent of its range of motion.
