Answer:
m=30.581kg
<em>If you use 10m/s/s for your value of g then the answer is 30kg)</em>
Explanation:
Assuming this is happening on earth, acceleration due to gravity (g) is 9.81m/s/s.
Force of gravity is the acceleration due to gravity multiplied by its mass:
F=mg
300=(9.81)m
m=30.581kg
<em>If you use 10m/s/s for your value of g then the answer is 30kg)</em>
Answer:
C.
Explanation:
Of the following activity best demonstrates the creativity of Rutherford: is making observations about the gold foil experiment.
Rutherford's Gold Foil Test confirmed the existence of a thin, enormous atom core that would later be recognized as an atom's nucleus. To examine the effect of alpha particles on material, Ernest Rutherford, Hans Geiger and Ernest Marsden conducted their Gold Foil Experiment.
Answer:
90 mAmps
Explanation:
V=IR
V/R = I
9 v / 100 ohm = .09 amps = 90 mAmps
Answer:
Second option 6.3 N at 162° counterclockwise from F1
Explanation:
<u><em>Observe the attached image</em></u>. We must calculate the sum of all the forces in the direction x and in the direction y and equal the sum of the forces to 0.
For the address x we have:
For the address and we have:
The forces and are known
We have 2 unknowns ( and b) and we have 2 equations.
Now we clear from the second equation and introduce it into the first equation.
Then
Then we find the value of
So the answer is 6.3 N at 162° counterclockwise from F1
