Answer:
The minimum frequency required to ionize the photon is 111.31 × 
Hertz
Given:
Energy = 378 
To find:
Minimum frequency of light required to ionize magnesium = ?
Formula used:
The energy of photon of light is given by,
E = h v
Where E = Energy of magnesium
h = planks constant
v = minimum frequency of photon
Solution:
The energy of photon of light is given by,
E = h v
Where E = Energy of magnesium
h = planks constant
v = minimum frequency of photon
738 × 
= 6.63 × 
× v
v = 111.31 × Hertz
The minimum frequency required to ionize the photon is 111.31 × Hertz
G.P.E = mgh
Weight = mg = 200N
So G.P.E = 200 * 2 = 400 Joules
The force on the object has a constant strength, but its direction
keeps changing. The force is always directed from the object to
the center of the circle. It's called "centripetal force".

Explanation:
sigh its not that hard
Any liquid takes form of the shape of the container it goes into.
Gasses take the form of the whole thing because it spreads throughout it.
Solids are already a shape so it cant take the shape of the container if it already has one. yk
Answer:
In the visible spectrum of light, the color of the light depends on the frequency. The visible spectrum is always the same for a rainbow or the separated light from a prism. The order of colors is red, orange, yellow, green, blue, indigo, and violet.
