If you found yourself on the see-through side of this one-way mirror what is the best way you could prevent someone on the other
Taya2010 [7]

Answer:

If there is any sheets or padded material in this room you can cover the window, you could turn off all the lights if there is a light switch in the room,   you could try to bring a bright flashlight in and shine it into the other room(try to annoy the person watching you so they leave), act really boring and hopefully make the other person lose interest.

Explanation:

(hint) If you actually get in a situation like this place your fingernail against the mirror or glass you think could possibly be a one-way mirror. If there's a gap between your nail and the mirror, it's most likely a genuine mirror :)

An ice block measuring 5cm by 5cm by 5cm has a desity of 5g/cm3. What is the mass of the ice block?
Svetradugi [14.3K]


Density = (mass) / (volume)

Volume of your block = (5cm x 5cm x 5cm) = 125 cm³

5 gm/cm³ = (mass) / (125 cm³)

Multiply each side by (125 cm³):  Mass = 625 gm

Note: 
I don't know what kind of frozen substance you're working with,
but maybe you ought to be careful handling it ... I know that's
not water ice you have there.  The density of water ice is not
5 gm/cm³.  In fact, it's a little less than 1 gm/cm³.  That's why
the ice floats in your soda.

You are explaining to your friends why astronauts feel weightless while orbiting in the space shuttle. They ask you to prove thi
meriva

Answer:

Explanation:

Force of gravity = GMm/r^2 = ma

a being the acceleration due to gravity at some distance r from the center of the Earth.  I'll use 6400 km for the radius of the Earth so r = 6734 km or 6734000 meters

a = GM/r^2

plugging in G = 6.67 x 10^-11

M is the mass of the Earth = 6 x 10^24

and r is from above

a = 8.825 m/s^2  = 0.9g

so 90% the acceleration of gravity on the surface.
