Prior to determining the
experimental design, a scientist typically forms a hypothesis. The answer is
letter B. this is to prepare the scientist, the possible outcome of their
research before the experimental design whether they are wrong or not.
Running on sand requires 1.6 times more energy spent than running on hard surface, so the force applied by our foot on sand is less.
The nicotine in cigarette smoke<span> is a big part of hypertension. It </span>raises<span> your </span>blood pressure<span> and heart rate, makes your arteries more narrow and hardens their walls, and also makes your </span>blood<span> more likely to clot. Hope this answers the question.</span>
Answer:
wavelength = v/f or wavelength equals to velocity over frequency
frequency= v/w or velocity over wavelength
frequency= 1/p or one over period or time
The gravitational force between the Earth and the satellite (its "weight") is inversely proportional to the distance between the centers of both objects.
On the surface, their centers are separated by 1 Earth radius.
12,000 miles above the surface, they're separated by 4 Earth radiii.
(4/1) = 4
So after the move, the satellite's weight is (1/4²) = 1/16 of its surface weight.
(321 lb) / (16) = (20 and a hair) lb
The correct choice from the given list is " <em>>20 lb "</em> .
