what is the net electric potential, in volts, at the point where the 7 nc charge is placed in the drawing below?
The electric potential of a point charge is V=kQ/r. A scalar is an electric potential, while a vector is an electric field.
The voltage due to a combination of point charges is obtained by adding voltages as integers, whereas the overall electric field is obtained by adding individual fields as vectors. When electrostatic forces are applied, the electric potential at a place in an electric field is the amount of work done transferring a unit positive charge from infinity to that point along any path. Because the work done on the item is equal to mgh, the energy gained by the object Equals mgh, which in this case is the potential energy E, according to the rule of conservation of energy.

Classify statements about total internal reflection true or fal False Answer Bank When light hits a boundary at less than the critical angle, it will undergo total internal reflection Simple reflection of light off a silvered mirror is more efficient than total internal reflection, so mirrors are often used instead of prisms in optical instruments to minimize light loss. A smaller critical angle means that total internal reflection is more likely to occur. Piber optic cables are a practical application of the phenomenon of total internal reflection.
In the field of physics, total internal reflection refers to the entire reflection of a beam of light that is traveling through a medium such as water or glass back into the medium itself from the surfaces that surround the medium.
When the angle of incidence is larger than a specific limiting angle, which is referred to as the critical angle, the phenomena will take place. When a ray of light traveling through a medium with a higher index of refraction approaches another medium with an angle of incidence that is greater than the critical angle, a phenomenon known as total internal reflection occurs. In general, this phenomenon takes place at the boundary between two transparent media.
True statements are;
1. A smaller critical angle means the total internal reflection is more likely to occur.
2. Fiber optic cables are practical applications of total internal reflections.
False statements are;
1. When light hits a boundary at a less than the critical angle, it will undergo total internal reflection.

Calcium is released by the action of osteoclasts which break down bone matrix.
The cells known as osteoclasts are responsible for breaking down bone to start the process of normal bone remodeling and for mediating bone loss in pathologic situations by escalating their resorptive activity. They develop in the bone marrow from progenitors in the myeloid/monocyte lineage, which then circulate in the blood. The Howship lacunae, which osteoclasts occupy on the surface of the bone, are assumed to be the result of the osteoclasts' enzymes eroding the bone. The union of many cells produced from blood-circulating monocytes results in osteoclasts. These are derived from the bone marrow in turn.

What is free fall?
Free fall is a concept of motion where an object is falling under the force of gravity and is only subjected to the force of gravity. It is experienced by objects that are not subject to any other type of force such as air resistance or drag. Examples of objects in free fall include an object dropped from a certain height, a skydiver in a belly-to-earth position, a spacecraft in orbit, or an object thrown upwards and then falling back down. A free fall can be thought of as a state of weightlessness, since the object is not subject to any other force, and is accelerating at a rate of 9.8 m/s2 (or 32 ft/s2). This acceleration is due to gravity and is known as the acceleration due to gravity.
Height from which the bullet id fired, h = 0.981 m
initial velocity of the bullet, u₁ = 981 m/s
Since it is fired parallel to the ground , the initial velocity u₁ does not have a vertical component
So it will be a free fall
Therefore the time taken to reach ground , t =√(2h/g)
t = √(2 * 0.981 / 9.81)
= √(1/5)

Can ballistic stretching be harmful?
Yes, Ballistic stretching can be harmful if it is not performed properly.
This type of stretching involves bouncing movements, which can place excessive strain on the muscles and connective tissues. This can lead to muscle strains or tears, as well as other injuries. It is important to use caution when performing ballistic stretches and to stop if any pain or discomfort is experienced. It is also recommended to warm up before stretching and to stretch slowly and smoothly, rather than using ballistic movements.
Ballistic stretching can also increase the risk of muscle imbalances and poor posture if it is not balanced with other types of stretching, such as static stretching. It is generally more effective and safer to gradually increase flexibility through regular, consistent stretching rather than trying to force the body to stretch too quickly or aggressively.
