Some springs are wound with the wire under torsion, so that they are naturally tightly compressed. The plot of extension vs. app
ANEK [815]

The "unstretched length" is shorter than the actual unloaded length because the load applied to the material caused the extension of the material thereby increasing its length.

<h3>Hooke's law</h3>

Hooke's law states that the force applied to an elastic material is directly proportional to the extension of the elastic material.

F = kx

where;

  • F is the applied force
  • k is the spring constant
  • x is the extension

Thus, we can conclude that, the "unstretched length" is shorter than the actual unloaded length because the load applied to the material caused extension of the material thereby increasing the length of the material.

The force per meter between the two wires of a jumper cable being used to start a stalled car is 0.244 N/m. (a) What is the curr
MakcuM [25]

Answer: current I is 144amp(A)

Explanation: The force per lenght F/L, current l, and separation distance r are related by the formula

F/L = permeability of space* I²/2*pi*r

Permeability of free space is 1.257*EXP {-6} Henry/meter

F/L is 0.244 N/m, pi is 3.142,

r is 1.7cm which is equal to 0.017meter.

I is what we are looking for.

Now we have after substitution,

0.244

= 1.257*EXP {-6} * I²/(2*3.142*0.017)

After cross multiplying and making I² subject of formula we have,

0.0261/(1.257*EXP {-6}) = I²

I = √{20736.7} =144ampere(A)

That means in each of the jumper wire there is 144amp(A)

What is a current potential difference graphs?
alexandr402 [8]

Answer:

Explanation:

Voltage and current in resistors

A graph of current against potential difference shows you how the current flowing through a component varies with the potential difference across it. The current flowing through a resistor at a constant temperature is directly proportional to the potential difference across it.

At the local swimming pool, the diving board is elevated h = 8.5 m above the pool surface and overhangs the pool edge by L = 2 m
Tasya [4]

Answer:

Part a)

t_w = \sqrt{\frac{2h}{g}}

Part b)

t_w = 1.32 s

Part c)

d_w = 6.88 m

Explanation:

Part a)

As we know that the diver will have zero velocity in vertical direction

so here we can say that

\Delta y = v_y t + \frac{1}{2}a_y t^2

h = \frac{1}{2}gt^2

t_w = \sqrt{\frac{2h}{g}}

Part b)

as we know that

h = 8.5 m

g = 9.81 m/s^2

so we will have

t_w = \sqrt{\frac{2(8.5)}{9.81}}

t_w = 1.32 s

Part c)

Distance covered by diver from the edge of the pool is given as

d_w = L + v_w t_w

d_w = 2 + (3.7)(1.32)

d_w = 6.88 m
