A 0.30-kg flying pig toy is attached to the ceiling with a string. When the pig’s wings flap, it moves at a constant speed of �

= 2.00 m/s in a horizontal circle of radius � = 0.25 m. Find the angle � the string makes with the vertical.

Answer:

58.5 deg

Explanation:

v = mass of the pig toy = 0.30 kg

v = speed of the toy = 2 m/s

r = radius of the circle = 0.25 m

\theta = Angle of the string with the vertical = ?

T = Tension force in the string

Using equilibrium of force in vertical direction

T Cos\theta = mg                                     eq-1

Along the horizontal direction, the component of tension force provides the necessary centripetal force, hence

T Sin\theta = \frac{mv^{2}}{r}                                  eq-2

Dividing eq-2 by eq-1

\frac{T Sin\theta}{T Cos\theta} = \frac{\frac{mv^{2}}{r}}{mg}

tan\theta= \frac{v^{2}}{rg}

tan\theta= \frac{(2)^{2}}{(0.25)(9.8)}

tan\theta = 1.63

\theta = 58.5 deg

What material parameters determine resistivity?
sleet_krkn [62]

Answer:

Resistivity \rho =\frac{RA}{l}

It depends upon cross sectional area and length of material

Explanation:

The resistance of any material is given by R=\frac{\rho l}{A}, here \rho is the resistivity of material , l is length of material and A is cross sectional area

So resistivity \rho =\frac{RA}{l}

So resistuivity of any material depends upon area of cross section and length of material

If cross sectional area will be more then resistivity will be more. And is length of the material will be more then resistivity will be less

A circus act involves a trapeze artist and a baby elephant. They are going to balance on a teeter-totter that is 10 meters long
elena-s [515]

Answer:

Explanation:

Balance point will be achieved as soon as the weight of the baby elephant creates torque equal to torque created by weight of woman about the pivot. torque by weight of woman

weight x distance from pivot

= 500x 5

= 2500 Nm

torque by weight of baby woman , d be distance of baby elephant from pivot at the time of balance

= 2500x d

for equilibrium

2500 d = 2500

d = 1 m

So elephant will have to walk up to 1 m close to pivot or middle point.
