The correct answer is C. Since that really was a tricky question I made sure it was correct by checking on Google. Hope I helped! - Amber
Answer:
Passive solar heating uses building design to utilize sunlight, while active solar heating uses technology.
Explanation:
lol
Simply, apply the formula
and insert the values of m = mass, v = velocity and E = Energy.
The result will be
, m = 1 kg
The refractive index for glycerine is
, while for air it is
.
When the light travels from a medium with greater refractive index to a medium with lower refractive index, there is a critical angle over which there is no refraction, but all the light is reflected. This critical angle is given by:
where n1 and n2 are the refractive indices of the two mediums. If we susbtitute the refractive index of glycerine and air in the formula, we find the critical angle for this case:
Answer:
I'm pretty sure its B and C
Explanation:
B bc the weight is gravitational pull x mass so when the object has same mass the weight is smaller on moon
C bc mass is the same - you can't change it
