I believe the answer is two convex lenses. A compound microscope has two systems of lenses for greater magnification, the ocular, or eyepiece lens that one looks into and the objective lens, or the lens closest to the object. Both the ocular lens and the objective lens are convex lens.
Answer:
C) either of these depending on speed
Explanation:
In classical mechanics, the momentum of a body is defined as the product of its mass and its velocity at a given time. Although the bullet has a smaller mass than the container ship, its momentum may be greater or lesser than container ship's, depending on its speed.
Answer:
Schrodinger's cat explains that the state of an object is not known until
an observer observes the state - therefor if the cat is in an enclosed box and the probability of some toxic substance escaping is 1/2, the cat is 1/2 dead and 1/2 alive until its actual state is observed by an external observer. An old saying "is the moon really there if no one is looking at it"
Answer:
10.95 minute
Explanation:
V = 120 V, I = 2 A, m = 0.489 kg, c = 4186 J/kgC, T1 = 23 C , T2 = 100 C
Let time be the t.
Heat energy is equal to electrical energy
m x c (T2 - T1) = V x I x t
0.489 x 4186 x (100 - 23) = 120 x 2 x t
t = 656.73 second
t = 10.95 minute
