Answer:
By using observations from the Atacama Cosmology Telescope (ACT) in Chile, the new findings match the measurements of the Planck satellite data of the same ancient light.
Explanation:
The correct answer is C, right-side up and smaller.
It is the most common example of spherical mirrors. The inside of the spoon acts like a concave mirror and the back side of it like a convex mirror.
A convex mirror always forms a real and diminished image. That is, the image formed is erect or right-side up and smaller in size. Therefore, Lin Yao should describe her reflection on the back side of the mirror to be right-side up and smaller.
A change that would most improve his results would be; D) Connecting the galvanometer to the coil
Answer: One thing magnetism and electricity have in common is that they are related.
Explanation: Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow.
Potential energy is defined by formula
here
m = mass
g = acceleration due to gravity
h = height
Now here two different stones are located at same height
while mass of stone A is twice that of stone B
so here we can say potential energy of A is
Similarly potential energy of B is
now if we take the ratio of two energy
so we can say potential energy of stone A is two times the potential energy of B
