Answer:
The maximum potential energy of the net, compared to its unstretched potential energy, is:
Explanation:
From the question we are told that
The weight of the man is
The distance of the window to the net is
The distance stretched by net is
Generally from the of conservation energy , the total energy is conserved
This implies that
Where is the initial potential energy of the , man which is mathematically evaluated as
Substituting values
And is the unstretched potential energy of the net
And is the final potential energy of the man which is mathematically evaluated as
Substituting values
The negative show that the direction of the man is against the direction of gravitational pull
And is the maximum potential energy of the net when stretched
So the above equation becomes
So
The city monitors the steady rise of CO from various sources annually. In the year "C: 2019"<span> (rounded off to the nearest integer) will the CO level exceed the permissible limit.
If this isn't the answer, let me know and i'll figure out what it is. But I believe this is it. :) </span>
Answer:
Vectors have both magnitude and direction
Explanation:
Vectors show how strong the force in because the bigger the arrow, the stronger the force. Also, it obviously shows direction because its an arrow.
Answer:
0.4752 oz.
Explanation:
Length = 1000 ft
Converting ft to inches,
12 in = 1 ft
1000 ft = 1000 * 12
= 12000 in
0.05082 in = 0.12908 cm
Mass = 19.8 lb
Converting lb to oz,
1 ounce = 0.0625 lb
1 lb = 1/0.0625 oz
19.8 lb = 1/0.0625 * 19.8
= 316.8 ounce
Since, 12000 in of copper wire weighs 316.8 ounces.
Therefore, 1 in will weigh = 316.8/12000
= 0.0264 oz
18 in = 0.0264 * 18
= 0.4752 oz.
Answer:
E = 2k
Explanation:
Gauss's law states that the electric flux equals the wax charge between the dielectric permeability.
We must define a Gaussian surface that takes advantage of the symmetry of the problem, let's use a cylinder with the faces perpendicular to the line of charge. Therefore the angle between the cylinder side area has the same direction of the electric field which is radial.
Ф = ∫ E . dA = E ∫ dA = q_{int} /ε₀
tells us that the linear charge density is
λ = q_ {int} /l
q_ {int} = l λ
we substitute
E A = l λ /ε₀
is area of cylinder is
A = 2π r l
we substitute
E =
E =
the amount
k = 1 / 4πε₀
E = 2k
