Answer:
I have a screenshot of this.
Explanation:
Formula for potential energy is:
pe = m * g * h
Where:
m = mass of an object
g = gravitational acceleration
h = height at which object is placed
From this equation we can make conclusion that increasing mass also increases potential energy. Object b has double the mass so it has double the potential energy.
Object a:
pe = m * 9.81 * 1
pe = 9.81 J
Object b:
pe = 2m * 9.81 * 1
pe = 19.62 J
Answer:
You'll see it without noticing
Explanation:
for example: Magnets can pull to one thing, but using the other side of the magnet with the other magnet can push away the magnets, and turn it to their way of pulling, also electricity, movement, were making energy everyday, just by moving
The focal Length of the eye is 0.37cm.
The retina, which is always 2.70 cm away from the lens, serves as the image's primary imaging medium. Image distance is 2.70 cm as a result.
The object is located 265 cm away from the eye's lens.
Based on lens formula:
where the object distance is u, the image distance is v, and the focal length is f.
Consequently, u is 265.00 cm and v is 2.70 cm.
f = 0.37
Thus, the focal length of the eye is 0.37cm.
