Rudiy274 years ago
3 0

Answer:

we can say that wind energy is due to

D) Severe thunderstorms

Explanation:

As we know that wind energy is converted into kinetic energy of wind mills

This kinetic energy of wind mill is then converted into electrical energy using turbine

now we can consider here  energy conservation theory that energy is only converted from one form to other form

it neither be destroyed nor be created but it can transfer from one form to other form

So here we can say that wind energy is due to

D) Severe thunderstorms

A 4.0 cm object is 6.0 cm from a convex mirror that has a focal length of 8.0 cm. What is the distance of the image from the mir
ioda

Mirror formula

1/f = (1/p) + (1/q)    [ f= focal length  ,  p= object distance ,  q = image distance ]

as given convex mirror so

distance of object =p= 6cm

focal length =  -8cm

to find q=?

1/q =( 1/f) - (1/ p)

1/q = (1/ 8) -(1/6)

1/q =-1/24

q=-24  ( negative sign shows image is virtual and behind the mirror)

Question 30
stellarik [79]

Answer: 0.69\°

Explanation:

The angular diameter \delta of a spherical object is given by the following formula:

\delta=2 sin^{-1}(\frac{d}{2D})

Where:

d=16 m is the actual diameter

D=1338 m is the distance to the spherical object

Hence:

\delta=2 sin^{-1}(\frac{16 m}{2(1338 m)})

\delta=0.685\° \approx 0.69\° This is the angular diameter
