Explanation:
Nuclear fusion can be more reliable than nuclear fission in energy generation due to the following reasons: There are no radioactive waste products obtained as a result of nuclear fusion, unlike nuclear fission. This is because the elements involved in Nuclear fusion are relatively radioactively stable elements.
Answer:
1438.4 N
Explanation:
Applying,
F = kqq'/r²................... Equation 1
Where F = Electrostatic force on the balloons, k = coulomb's constant, q = charge on the first balloon, q' = charge on the second balloon, r = distance between the two ballons.
From the question,
Given: q = q' = 4.0×10⁻⁵ C, r = 0.1 m
Constant: k = 8.99×10⁹ Nm²/C²
Substitute these values into equation 1
F = ( 4.0×10⁻⁵×4.0×10⁻⁵×8.99×10⁹)/0.1²
F = 14.384/0.01
F = 1438.4 N
Answer:
226.6 N
Explanation:
The work done by the push is given by:
where
p is the magnitude of the push
d is the displacement of the crate
is the angle between the direction of the push and the displacement of the crate
On the contrary, the work done by the frictional force is:
where
is the frictional force, with m=1.00x102 kg being the mass of the crate ang g=9.81 m/s^2 the gravitational acceleration
d is the displacement of the crate
the negative sign is due to the fact that the frictional force acts in the opposite direction to the displacement of the crate.
The net work must be zero, so:
Substituting the previous equations into this one, we find:
which we can solve to find p:
The answer is c.1,000 inches
