Answer:
F = Gm1m2/r^2 where G = 6.67x10^-11, m1 =1300, m2 = 7800, r = 0.23m
F = 6.67x10^-11 *1300*7800/(0.23)^2 = 0.0127852N
Explanation:
Using Newton's Second Law, we can find the air resistance. We know the net force is equal to mass times acceleration.
The answer is C. Bulimia. Osteoporosis is a bone condition. Alzheimer's disease is a mental disease. Menopause is when a women's reproductive organs become unable to bear a child (this usually happens around 40-50). Bulimia is an emotional disorder involving distortion of body image and an obsessive desire to lose weight.
<span>The answer is 6 kg the mass of the second
object. By using Inversely proportional formula it means that (14 kg) (3 m/s</span>²<span>)
= M (7 m/s</span>²<span>). Where M is the mass of the second object. For the
Newton’s second law of motion formula which is: Force = mass x acceleration, we
have:</span>
<span>F = (14 kg) (3 m/s</span>²<span>) = 42 N</span>
Therefore:
<span>42 N = M (7 m/s</span>²)
<span>M = (42 N) / (7 m/s</span>²<span>)</span>
M = 6 kg mass of the second object
Answer:
Explanation:
The ant is under an uniform motion. So, we get the time taken by the ant to cross the strip from the definition of speed:
In this case, we use the vertical speed of the ant (), since the ant crosses the strip that is 34.2 cm wide (vertically). So:
