You could attach both springs to the ceiling and hang the same mass from both. The one that stretches less has the larger spring constant value.

Consider two displacements, one of magnitude 3 m and another of magnitude 4 m. Show how the displacement vectors may be combined

Rufina [12.5K]

Answer:

Explanation:

A = 3m

B = 4 m

let the angle between the two vectors is θ.

the resultant of two vectors is given by

$R=\sqrt{A^{2}+B^{2}+2ABCos\theta }$

(a) R = 7 m

So, $7=\sqrt{3^{2}+4^{2}+2\times 3\times 4 Cos\theta }$

49 = 9 + 16 + 24 Cosθ

Cosθ = 1

θ = 0°

Thus, the two vectors are inclined at 0°.

(b) R = 1 m

So, $1=\sqrt{3^{2}+4^{2}+2\times 3\times 4 Cos\theta }$

1 = 9 + 16 + 24 Cosθ

Cosθ = - 1

θ = 180°

Thus, the two vectors are inclined at 180°.

So, $5=\sqrt{3^{2}+4^{2}+2\times 3\times 4 Cos\theta }$

25 = 9 + 16 + 24 Cosθ

Cosθ = 0

θ = 90°

Thus, the two vectors are inclined at 90°.

A businesswoman is rushing out of a hotel through a revolving door with a force of 80 N applied at the edge of the 3 m wide door

mel-nik [20]

Answer:

Explanation:

Given

Force applied $F=80\ N$

Door is $d=3\ m$ wide

for gate to revolve Properly Pivot Point must be at center i.e. 1.5 from either end

Torque applied is $T=force\times distance$

Maximum torque

$T_{max}=F\times \frac{d}{2}$

$T_{max}=80\times \frac{3}{2}$

$T_{max}=120\ N-m$

What percentage of the intensity gets through both polarizers?

sp2606 [1]

Answer:

if the two polarizers have the same direction the transmitted light is 50% of the incident and if the two polarizers are at 90º the transmitted light is zero

Explanation:

The incident light is generally random, that is, it does not have a polarization plane, when the first polarized stops by half, this already polarized light arrives at the second polarizer and the causticity passes

I = I₀ cos² θ

therefore if the two polarizers have the same direction the transmitted light is 50% of the incident and if the two polarizers are at 90º the transmitted light is zero
