Answer:
The ratio of the energy stored by spring #1 to that stored by spring #2 is 2:1
Explanation:
Let the weight that is hooked to two springs be w.
Spring#1:
Force constant= k
let x1 be the extension in spring#1
Therefore by balancing the forces, we get
Spring force= weight
⇒k·x1=w
⇒x1=w/k
Energy stored in a spring is given by where k is the force constant and x is the extension in spring.
Therefore Energy stored in spring#1 is,
⇒
⇒
Spring #2:
Force constant= 2k
let x2 be the extension in spring#2
Therefore by balancing the forces, we get
Spring force= weight
⇒2k·x2=w
⇒x2=w/2k
Therefore Energy stored in spring#2 is,
⇒
⇒
∴The ratio of the energy stored by spring #1 to that stored by spring #2 is 2:1

R = spool of radius
The equation is:
(eq. 1)
The sum of forces in y:
∑Fy = Mg - T = Ma
Replacing in eq. 1
Answer:b) atoms
Explanation:which are in turn made up of protons, neutrons and electrons
Answer:
The value of tangential acceleration 40
The value of radial acceleration
Explanation:
Angular acceleration = 50
Radius of the disk = 0.8 m
Angular velocity = 10
We know that tangential acceleration is given by the formula
Where r = radius of the disk
= angular acceleration
⇒ 0.8 × 50
⇒ 40
This is the value of tangential acceleration.
Radial acceleration is given by
Where V = velocity of the disk = r
⇒ V = 0.8 × 10
⇒ V = 8
Radial acceleration
This is the value of radial acceleration.
