We can conclude that as the mass on the right increases, the distance of the mass towards the right decreases. Also when the two masses balance, the net torque is zero.
<h3>What is torque</h3>
The torque experienced by an object a given position is the product of the applied force and the perpendicular distance of the object.
When 5 kg mass is at 2 m on the left, another 5 kg at 2 m on the right will balance it.
<h3>Position of 10 kg mass on the right</h3>
Apply principle of moment
<h3>Net torque</h3>
<h3>Position of the 20 kg mass</h3>
<h3>Net torque</h3>
Thus, we can conclude that as the mass on the right increases, the distance of the mass towards the right decreases. Also when the two masses balance, the net torque is zero.

Complete Question
A parallel plate capacitor contains a positively charged plate on the left, and a negatively charged plate on the right. An electron in between the plates is moving to the right. Which statement is true?
Group of answer choices
a The potential energy of the electron is decreasing and it is moving to a region having a higher potential
b The potential energy of the electron is decreasing and it is moving to a region having a lower potential.
c The potential energy of the electron is increasing and it is moving to a region having a lower potential
d The potential energy of the electron is increasing and it is moving to a region having a higher potential.
Answer:
The correct option is C
Explanation:
From the question we are told that
An electron in between the plates is moving to the right
Generally the potential energy of the electron is mathematically represented as
Here e is the charge on the electron and V is the electric potential of the electron
Generally the left side with the positive charge has a higher potential than the right side with the negative charge
Now when the potential energy of the electron increases it will move toward the plate with the lower potential which is the left plate
The answer is that it showed the scientist that on the area of the mantle from the subduction zones the slabs of the ocean floor remains or returns after such tectonic movement or earthquakes.
Answer:
a) Maximum altitude of the projectile,
b) v = 10885.7 m/s
Explanation:
a) Mass of the earth,
Mass of the projectile =
Launch speed, v = 2.31 * 10³ m/s
Earth radius, r = 6.36 ✕ 10⁶ m
Workdone by the projectile against gravity
...............(1)
Kinetic energy of the projectile:
...................(2)
Equating (1) and (2) based on the law of energy conservation
b) Smallest required change in the satellite speed
Altitude, h = 352 km = 352000 m
Earth radius, r = 6.38 * 10⁶ m
v = 10885.7 m/s
Horizontal angulation is Select one: a. the side-to-side angulation. b. different when using the paralleling and bisecting techniques.
Angles that are horizontal. relates to the central ray's placement in a horizontal, or side-to-side, plane.
A picture with an overlap of nearby structures in the horizontal plane is produced by situating the central ray such that the horizontal angulation is not directed through the interproximal contacts of the adjacent teeth (the contact areas of the teeth are superimposed over each other).
Fracture angulation refers to a particular kind of fracture displacement in which the bone's natural axis has been changed so that the distal end now points off in a different direction. When using a bite-wing tab, the x-ray beam's center ray must be pointed at the contact points between teeth. The x-ray beam must be centered on the receptor to guarantee that the receptor is exposed.
