The smallest unit that makes up matter is an atom!
Starting with the equation for newtons second law of motion:
Answer:
Explanation:
position
y(t) = 2.80t + 0.61t³
velocity is the derivative of position
v(t) = 2.80 + 1.83t²
acceleration is the derivative of velocity
a(t) = 3.66t
F = ma = 5.50(3.66(4.10)) = 82.533 N
which should be rounded to no more than three significant digits and arguably only two due to the 0.61 factor.
F = 82.5 N or 83 N
Yes the units are Newtons, cannot tell what your system will accept. May not want the units at all.
Answer:
1782.7 N/C, downward
Explanation:
Since the charged sphere is in static equilibrium, it means that the electric force acting is balanced with the weight of the sphere, so we can write:
where
m = 3.62 g = 0.00362 kg is the mass of the sphere
g = 9.8 m/s^2 is the acceleration of gravity
is the magnitude of the charge
E is the magnitude of the electric field
Solving for E,
In order for the sphere to be in equilibrium, the electric force must be in opposite direction to the weight, so the electric force must point upward. Since the sphere has a negative charge, the electric field has opposite direction to the electric force: so, the electric field direction is downward.
