Answer:
The value of the spring constant of this spring is 1000 N/m
Explanation:
Given;
equilibrium length of the spring, L = 10.0 cm
new length of the spring, L₀ = 14 cm
applied force on the spring, F = 40 N
extension of the spring due to applied force, e = L₀ - L = 14 cm - 10 cm = 4 cm
From Hook's law
Force applied to a spring is directly proportional to the extension produced, provided the elastic limit is not exceeded.
F ∝ e
F = ke
where;
k is the spring constant
k = F / e
k = 40 / 0.04
k = 1000 N/m
Therefore, the value of the spring constant of this spring is 1000 N/m
Explanation:
Assuming a uniform mass, let's say ρ is the mass per area density.
ρ = M / (πR²)
Let's look at this as the difference of two disks, a large one and a small one.
The moment of inertia of the large disk is:
I = 1/2 MR²
The mass of the small disk is:
m = ρ πr²
m = M / (πR²) πr²
m = M (r/R)²
Using parallel axis theorem, the moment of inertia of the small disk is:
I = 1/2 mr² + md²
I = 1/2 M (r/R)² r² + M (r/R)² d²
I = 1/2 M (r²/R)² + M (rd/R)²
The total moment of inertia is:
I = 1/2 MR² − 1/2 M (r²/R)² − M (rd/R)²
The displacement is the straight-line distance it flew when everything is over. We don't count all of the turns that it made in the displacement. So if it's in an opposite corner we just need to know how far it is from one corner of a box to the opposite corner with the given dimensions. We use the Pythagorean Theorem for part a):
b). Since the displacement is the straight line path, there are no shorter paths that this.
c)All other paths are greater
d) if the fly flies this path, then they would be equal
in cartesian coordinates, the vector is the sum of the 3 components whose magnitudes are the wall lengths and whose directions are parallel to that wall:
The shortest walking path is 7.96m.
Answer;
Amount of time the two substances are in contact
Area in contact between the two substances
Specific heat of the material that makes up the substances
Explanation;
The change in temperature of a substance is caused by heat energy. The change in temperature will depend on factors such as mass of the substance, the type of material it is made from, the time taken , specific heat of the material that makes the substance, and also the area of contact.
The amount of time the two substances are in contact affect the change in temperature such that if the two bodies are in contact for a longer time then a bigger change in temperature will be observed.
Specific heat capacity also determines the change in temperature that will be observed, such that a substance with a bigger specific heat capacity will record a small change in temperature.
