A fire helicopter carries a 580-kg bucket of water at the end of a 20.0-m long cable. Flying back from a fire at a constant spee

d of 40.0 m/s, the cable makes an angle of 38.0° with respect to the vertical. Determine the force exerted by air resistance on the bucket.

Answer:

F = 41,954 N

Explanation:

given,

mass of bucket = 580 Kg

length of the cable = 20 m

velocity = 40 m/s

angle made = 38.0°

T cos 38° = m g..............(1)

T sin 38^0 = \dfrac{mv^2}{l} + F......(2)

dividing equation (2) by (1)

tan 38^0 = \dfrac{\dfrac{mv^2}{l} + F}{mg}

tan 38^0 = \dfrac{\dfrac{580\times 40^2}{20} + F}{580 \times 9.81}

4445.36 = \dfrac{580\times 40^2}{20} + F

F = -46400 + 4445.36

F = -41,954 N

hence, the force is acting in the opposite direction as assumed.

F = 41,954 N

Calculate the speed of light in glycerol (n = 1.47). Use the GRASS method, write your solution on paper and insert an image of i
Degger [83]

The velocity of light in glycerol is 2.04 × 10⁸ m/s.

To find the answer, we need to know about the expression of velocity of light in any medium.

<h3>What's the expression of the speed of light in any medium?</h3>
  • Mathematically, the speed of light in any medium= C/n
  • C = speed of light in vaccum, n = refractive index of the medium

<h3>What's the speed of light in glycerol having refractive index of 1.47?</h3>

Speed of light in glycerol= 3×10⁸/1.47 = 2.04 × 10⁸ m/s

Thus, we can conclude that the velocity of light in glycerol is 2.04 × 10⁸ m/s.
