To solve this problem it is necessary to apply the concepts related to the kinetic energy expressed in terms of simple harmonic movement, as well as the concepts related to angular velocity and acceleration and linear acceleration and velocity.
By definition we know that the angular velocity of a body can be described as a function of mass and spring constant as
Where,
k = Spring constant
m = mass
From the given values the angular velocity would be
The kinetic energy on its part is expressed as
Where,
A = Amplitude
= Angular Velocity
PART A) Replacing previously given values the energy in the system would be
PART B) Through the amplitude and angular velocity it is possible to know the linear velocity by means of the relation
PART C) Finally, the relationship between linear acceleration and angular velocity is subject to
Answer:
2.36 μ H
Explanation:
Given,
Number of turns= 90
diameter = 1.3 cm = 0.013 m
unscratched length = 57 cm = 0.57 m
Area, A = π r²
= π x 0.0065² = 1.32 x 10⁻⁴ m²
we know,
L = 2.36 μ H
Hence, the inductance of the unstretched cord is equal to 2.36 μ H
Answer:
New gravitational force would be: 
Explanation:
Recall the general form of the gravitational force between two objects of masses m1 and m2 separated a distance "d":
which for the 2000 kg trucks becomes:
when we add 1000 kg of bricks to one truck, we get the following unknown force (x) that we need to find:
Now we divide term by term the last equation by the previous one, in order to cancel out common factors to both equation (G, d^2) and get the following equation:
Answer:
Glucose, starch and cellulose are all carbohydrates.
Answer:
The space surrounding a charged object is affected by the presence of the charge; an electric field is established in that space. A charged object creates an electric field - an alteration of the space or field in the region that surrounds it. Other charges in that field would feel the unusual alteration of the space.
