The tension in the rope is 490 N.
The force balancing principle can be used to determine each strand's tension. The girl must be subject to zero forces overall because she is hanging vertically and not moving at all. This indicates that the tension in the ropes acting upward balances the force of gravity acting downward.
Let's refer to each rope's tension as T. In that case, the force balance equation would look like this:
T + T = m * g
where g is the acceleration caused by gravity (9.8 m/s2) and m is the girl's mass (200 N).
2T = m * g 2T = 200 N * 9.8 m/s2 2T = 980 N / 2T = 490 N 2T = m * g
Thus, there is 490 N of strain in each strand.

an inquisitive physics student and mountian climber climbs a 44.3 m cliff that overhangs a calm pool of water. he throws two stones vertically downward, 0.75 s apart and observes that they cause a single splash. the first stone has an initial velocity of 1.75 m/s. how long after release of the first stone do the two stones hit the water?
It will take 6.7secs to hit second stone after the first stone of velocity 1.75m/s.
We set [tex]y_{i}[/tex] =0 at the top of the cliff, and find the time interval required for the first stone to reach the water using the particle under constant acceleration model:
[tex]y_{r} = y_{i} + v_{yi}t + \frac{1}{2} a_{y} t^{2}[/tex]
If we take the direction downward to be negative,
[tex]y_{f} = -44.3 m, v_{yi} = -1.75 m/s, and a_{y} = -9.80m/s^{2}[/tex]
Substituting these values into the equation, we find
[tex](4.90m/s^{2} )t^{2} + (1.75m/s)t - 44.3m = 0\\[/tex]
We now use the quadratic formula. The stone reaches the pool after it is thrown, so time must be positive and only the positive root describes the physical situation:
[tex]t = -1.75m/s + \sqrt{1.75m/s^{2} - 4(4.90m/s^{2} (- 44.3m)} / 2(4.90m/s^{2} )[/tex]

(d) Electric field lines point outwards from positive charge.
(e) Electric field lines point inwards towards negative charge.
(f) Where the electric field lines are dense the electric field must be weak.
(g) A positive point charge released from rest will initially accelerate.
1) A things along the way charge will initially accelerate down an E-field line when it is released from rest: TRUE.
When the force of the electrostatic potential that generates the field is applied to the electric field lines, they all point in the exact direction that will produce a positive test charge.
2) E-Field lines encircle positive charges in circles: FALSE.
With the exception of infinity, E-Field lines begin with positive charges and end with negative charges.
3) E-field lines are oriented inward and toward electrostatic repulsion: TRUE
Negative charges attract positive charges, therefore the positive test charging will move in the direction of the negative charges as the E-field lines move along trajectory that would include a positive drug test charge.
4) E-Field vector may intersect: FALSE
If they crossed, it would imply that the electric potential may be developing variably at the exact spot, which is not conceivable because the E-Field seems to be the gradient of both the electrostatic attraction (thus they have always had the direction of the highest change of potential).
5) Positive charges have E-Field lines pointing outward: TRUE
According to the previous explanation, the E-field traces follow the path that a positive test charges would take if it were to produce the field. As a result, if a positive charge creates the field, the analysis suggests would move away from it, and the field lines would then point outward.
6) The E-field must really be weak when the E-field margins are dense: FALSE

the acceleration due to gravity on the moon is 1.62 m/s2, approximately a sixth of the value on earth. for a given initial velocity v0, and a given launch angle θ0, the ratio of the range of an ideal projectile on the moon to the range of the same projectile on earth, rmoon/rearth, will be approximately?
Answer:
approximately 1/6
Explanation:
The range of an ideal projectile depends on the initial velocity, the launch angle, and the acceleration due to gravity. The formula for the range of an ideal projectile is given by:
R = (v0^2 sin(2θ0)) / g
Where v0 is the initial velocity, θ0 is the launch angle, and g is the acceleration due to gravity.
For the moon, the acceleration due to gravity is 1.62 m/s^2, and for the earth, it is 9.8 m/s^2. The ratio of the ranges on the moon to the range on the earth can be expressed as:
rmoon/rearth = (1.62 * sin(2θ0)) / (9.8 * sin(2θ0)) = 1.62 / 9.8 = approximately 1/6
So, the range of an ideal projectile on the moon is approximately a sixth of the range of the same projectile on earth.

How long is my lens's focal length?The focal length of the lens, which is often expressed in millimeters, is the space between the lens as well as the image sensor whenever the subject is in focus .The maximum and minimum focal lengths of zoom lenses are specified, for instance, 18-55 mm.
How should I pick my focus length?The focal length that isolates the topic, or hero, in your image and keeps out all the distractions, or villains, is the optimal focal length. Select a long depth of field lens, such as one with a 70, 135 or 200mm aperture, to separate textures and far-off details to pace of innovation backgrounds.

) if a conductor is in electrostatic equilibrium near an electric charge 4) a) the force between the conductor and the charge must be zero. b) the electric field on the surface of the conductor is perpendicular to the surface. c) the total electric field of the conductor must be zero. d) the total charge on the conductor must be zero
Contrary to what we assumed, moving charges by definition indicate nonstatic situations. To put it another way, when electrostatic equilibrium is established, the charge is dispersed such that the electric field inside the conductor disappears.
Why does an electrical field in a conductor equal 0?Because in a good conductor, the charges always go and settle on the conductor's surface, leaving zero charge within and producing zero electric field, the strength of the electric field in a charged conductor is zero.
If an electrical charge is present near a conductor in electrostatic equilibrium, the charges within the conductor will rearrange, resulting in a zero net electric field inside the conductor.

ich of the following materials would you choose for optimal performance in the charge storage layer of a capacitor? which of the following materials would you choose for optimal performance in the charge storage layer of a capacitor? material a: high dielectric constant low electrical resistivity material b: low dielectric constant high electrical resistivity material c: low dielectric constant low electrical resistivity material d: high dielectric constant high electrical resistivity question at position 2 2 3 points
"Material A: high dielectric constant low electrical resistivity is best for optimal performance."
A capacitor is a device used to store electrical energy and it consists of two conductive plates separated by a dielectric material. The choice of material for the charge storage layer is important for determining the performance of the capacitor. The dielectric constant is a measure of a material's ability to store electrical energy and the electrical resistivity is a measure of a material's ability to conduct electrical current. For optimal performance in the charge storage layer of a capacitor, material A is the best choice as it has a high dielectric constant and low electrical resistivity. This means that the material has a high ability to store electrical energy and a low resistance to electrical current, making it ideal for use in a capacitor. Material B would not be an optimal choice for a charge storage layer as it has a low dielectric constant and high electrical resistivity, meaning that it is not an efficient material for storing electrical energy and has high resistance to electrical current.
