-- there's no normal force acting on the diving falcon

-- drag IS kinetic friction; both terms refer to the same single force

-- it might be a bit more elegant if you referred to a force as "gravity" instead of "weight"

Answer:

i think its because u gave the almost every answer the same exact thing. all the questions have different ways of moving which means different forces for each one i hope this helps :)

A 3,65 kg mass attached to a
motikmotik

This question involves the concepts of tension, weight, and centripetal force.

The maximum speed, the mass can have before the string breaks is "10.26 m/s".

First, we will find the maximum tension force:

Tension = Weight

T = W = mg = (32.4 kg)(9.81 m/s²)

T = 317.84 N

Now, this tension force must be equal to the centripetal force:

T = \frac{mv^2}{r}\\v=\sqrt{\frac{Tr}{m}}

where,

v = maximum speed = ?

r = radius = 1.21 m

m = mass = 3.65 kg

Therefore,

v=\sqrt{\frac{(317.84\ N)(1.21\ m)}{3.65\ kg}}\\

<u>v = 10.26 m/s</u>

The attached picture shows the centripetal force.

The critical angle between a medium and air is 430. What is the speed of light in that medium?
vagabundo [1.1K]

Answer:

The speed of light is that medium is 281907786.2 m/s.

Explanation:

since the critical angle is Фc = 430, we know that the refractive index is given by:

n = 1/sin(Фc)

  = 1/sin(430)

  = 1.06

then if n is the refractive index of the medium and c is the speed of light, then the speed of light in the medium is given by:

v = c/n

  = (3×10^8)/(1.06)

  = 281907786.2 m/s

Therefore, the speed of light is that medium is 281907786.2 m/s.
