A plane mirror forms a virtual image. give reasons ​
xenn [34]

Answer:

1. The reason why a plane mirror forms a virtual image is because it doesn't let the light go through it, but it reflects the light, so if you go behind the plane mirror, then you won't see the rays of light since it's not letting the rays of light go behind it.

2. The image cannot be projected onto a screen also.

3. Also, the Rays of light never meet at a focus point, so hence, this is why the plane mirror forms a virtual image.

Thanks!

Can anyone define thermostat and list electrical appliances that have a thermostat?
Tresset [83]
A thermostat is a switch that operates itself when the temperature
goes above or below a temperature that the user can set.

-- Before you go to bed, you set the thermostat for 65° .
If the temperature in the house goes below 65° during the night,
the thermostat turns on the furnace, and keeps it running until
the house warms up to 65°.  Then it shuts the furnace off.

-- After breakfast, you set the thermostat for 75°.
If the temperature in the house goes above 75°, during the day, 
the thermostat turns on the air conditioner, and keeps it running until
the house cools down to 75°.  Then it shuts the air conditioner off.  

-- On Sunday morning, you put the slow cooker on the kitchen counter,
and you throw in a big roast, a sliced onion, some baby carrots, some
sliced potatoes, some vegetable stock, salt, pepper, garlic, chili powder,
and tomato paste.  Then you put the cover on, turn the power on, and
set the slow cooker to "LOW".  The heater in the slow cooker turns on.
  Whenever the temperature in the crock gets higher than 160°, the
thermostat in the slow cooker turns off the heater, and keeps it off
until the crock cools down to 160°.  Then the thermostat turns the
heater on again.
  By dinner time, you have a hot, juicy, scrumptious pot roast, ready
to eat.  It's not too hot, not too cold, not too tough, not dried out, and
it melts in your mouth.
You're still thinking about it when you go to bed, and your mom gives you
a slice to take to school for your lunch on Monday.

Flying against the wind, an airplane travels 2670 km in 3 hours. Flying with the wind, the same plane travels 11,070 km in 9 hou
xxMikexx [17]

Answer:

speed of plane in still air = 1060 km/h

speed of wind = 170 km/h

Explanation:

Let teh speed of plane in still air is vp and the speed of air is va.

Irt travels 2670 km in 3 hours against the wind

So,

vp - va = 2670 / 3 = 890 km/h ..... (1)

It travels 11070 km in 9 hours along the wind.

vp + va = 11070 / 9 = 1230 km/h .... (2)

Adding both the equations

2 vp = 2120

vp = 1060 km/h

and va = 1230 - vp = 1230 - 1060 = 170 km/h
