To find acceleration of a ball down a ramp you have to:
Find the value of the gravity. If the object is on the earth it would be 9.8 Find the value of the angle of the field with the horizontal field.Find the value of the acceleration by multiply gravity with sinus angle.What is acceleration?Acceleration is a condition where the object are moving in different velocity each time where the value of difference has to be positive. Basic formula for velocity is ΔV : t. The opposite of acceleration is deceleration where the first velocity is higher than the second.

A worker drives a 0.5 kg spike into a rail tie with a 2.5 kg
sledgehammer. The hammer hits the spike with a speed of 65 m/s.
If 1/3 of the hammer's kinetic energy is converted into internal
energy, how much does the total energy increase?
The increase in internal energy will be 1760.42 J.
What is kinetic energy?kinetic energy is the energy of motion, observable as the movement of an object or subatomic particle. Every moving object and particle have kinetic energy. A person walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field are all examples of kinetic energy at work.The energy of a body due to its motion is called kinetic energy. - Every object around us which is moving possesses kinetic energy.Kinetic energy (KE) is the energy of a body in motion, which means it's essentially the energy of all moving objects. It is one of the two main forms of energy, along with potential energy, which is the stored energy contained within objects at rest.To learn more about kinetic energy refers to:

Forensic scientists immerse glass evidence into a medium to determine its refractive index. Which medium is usually used for determining the
refractive index?
O A. water
B.
air
O C.
OD. gel
oil
A) water medium is usually used for determining the refractive index.
What do you mean by Refractive physics?In physics, refraction is the direction change brought on by a wave's speed change as it travels through a medium. For instance, waves move more quickly in deep water than they do in shallow.
The most often investigated characteristic in the forensic analysis of glass pieces is refractive index since it is easily evaluated on the minuscule shards typically found in casework.
What is an example of a refraction?Glass is the ideal real-world illustration of light refraction. A glass jar will make an object appear smaller and a little elevated when viewed through it. The text on a piece of paper or a document will appear closer to the surface if a slab of glass is placed over it due to the different angle the light is bending at.

Does more bandwidth reduce latency?.
Yes, more bandwidth reduce latency.
Bandwidth reduces latency because there is a wider pipeline through which more data passes, reducing the chance of data packets being delayed. On the other hand, high latency can create bottlenecks and reduce effective bandwidth, at least until the delayed data packets get through.
Maximum amount of data sent over an Internet connection in a given period of time. Bandwidth is often confused with internet speed. It is actually the amount of information that can be transmitted over a connection in a given amount of time, calculated in megabits per second (Mbps) or wireless communication links for transmitting data over network connections. The period specified for the transfer. Bandwidth is usually expressed in the number of bits, kilobits, megabits, or gigabits that can be transmitted per second.

The table shows the relative atomic masses of some common elements. Use it to calculate the relative formula mass of sodium hydroxide, naoh.
Answer Relative Atomic Mass is - 39. 99
What is Relative Mass ?
-- Relative atomic mass, also known by the deprecated synonym atomic weight, is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant.
-- The atomic mass constant is defined as being 1/12 of the mass of a carbon-12 atom
What is Molar mass
-- The mass of mole of a substance is called its molar mass.
What Is absolute mass ?
-- The absolute mass of an electron is, however, 9 x 10-28 gram.
-- The electron in an atom possesses a certain amount of energy to maintain its distance from the oppositely charged nucleus.
-- Without this energy, the electron would collapse into the nucleus.

What is force multiplied by distance?.
Force multiplied by distance is nothing but work done. It can also be described as work done is the dot product of force and distance.
A force is a quantity which is a vector because it has both a magnitude and a direction. According to Newton's laws, the force acting on an item is what causes it to move or cease moving.
Force multiplied by distance equals work. Work is a form of energy that is expended as an object moves along certain distance. However, note that this particular formulation:
W = F d
The above equation works only if force is constant and if the movement is entirely linear on a flat surface. General formula for determining work can be done through calculus as:
W = ∫ F ds
where the distance becomes differential from d to ds, and allows us to evaluate the work done even for non-linear paths or on paths that are inclined at angles above the horizontal plane.

What is genetic screening?Genetic testing is helpful in many medical specialties and may alter the treatment you or a member of your family receives. Genetic testing, for instance, can diagnose a genetic disorder like fragile X-syndrome or reveal your risk of contracting cancer. Genetic testing come in a wide variety of forms. the process of screening people in a population to find out who is more likely to have or develop a certain genetic condition or to carry a genetic variation for that disorder. Sickle cell disease, Tay-Sachs disease, duchenne muscular dystrophy, haemophilia, Huntington's disease, and neurofibromatosis are a few conditions that may be screened for genetically.

what year was pluto reclassified as a dwarf planet
Pluto was downgraded to a dwarf planet by the International Astronomical Union (IAU) in 2006 because it failed to meet the three requirements for the definition of a full-sized planet.
Who originally demoted Pluto?
In a decision to more narrowly define a planet on August 24, 2006, the International Astronomical Union downgraded Pluto from the ninth planet from the sun to a dwarf planet, igniting a scientific and cultural debate.
Pluto was demoted in 2006; why?
Pluto is presently regarded as a dwarf planet because, while being huge enough to have grown spherical, it lacks the power to dominate its orbit and clear the area around it.
