Answer:

a. Effort = 960 Newton

b. Mechanical advantage (M.A) = 0.625

c. Velocity ratio (V.R) = 1.67

Explanation:

Given the following data;

Load = 600 N

Length of crowbar = 200 cm

Length of load arm = 0.75 m

Conversion:

100 cm = 1 m

X cm = 0.75 m

Cross-multiplying, we have;

X = 0.75 * 100 = 75 cm

First of all, we would find the effort arm;

Effort arm = length of crow bar - length of load arm

Effort arm = 200 - 75

Effort arm = 125 cm

Next, we would determine the mechanical advantage (M.A) of the crow bar;

Substituting the values into the formula, we have;

M.A = 0.625

To find the effort of the crow bar;

Making "effort" the subject of formula, we have;

Effort = 960 Newton

Lastly, we would determine the velocity ratio (V.R);

V.R = 1.67

Answer:a. Effort = 960 Newton

b. Mechanical advantage (M.A) = 0.625

c. Velocity ratio (V.R) = 1.67

A: Parallel

Explanation:

It's a parallel circuit because it has two or more paths for the electricity to flow through (the paths are parallel).

Answer:

A

Explanation:

The work input = Fi × di

To solve for work input, you need to know the force acting on an object and the distance it moves in the direction of the force. Work input is defined as the product of force and distance, given by the formula:

Work Input = Force × Distance × cosθ

Where θ is the angle between the force vector and the direction of motion. If the force is applied in the direction of motion, then θ = 0 and cosθ = 1, so the formula simplifies to:

Work Input = Force × Distance

For example, if you are pushing a box with a force of 50 newtons over a distance of 10 meters, the work input would be:

Work Input = 50 N × 10 m × cos(0°) = 500 Joules

Answer:

Friction

Explanation:

There are some forces that will work against the motion in every situation, the force of air resistance is often observed to oppose the motion of an object, Frictional Force, Gravitational Force, Normal Force,  Magnetic Force, and Tension Force.

Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces. For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.

Newton is a unit of force used by physicists that is part of the International System (SI). The force required to move a body weighing one kilogram one meter per second is known as a newton.

Therefore, the force of air resistance is often observed to oppose the motion of an object, Frictional Force, Gravitational Force, Normal Force,  Magnetic Force, and Tension Force.

2.The age of fossils are determined by carbon dating and by radioactive calculations. Since all living things are made up of carbon, the relative age of fossils, which were once live animal or plant life, can be calculated by estimating at what time the fossil was alive. When the sun’s rays shine on the animals or plants and when this collides with nitrogen it creates Carbon 14, a radioisotope. Superposition is the action of placing one thing on or above another, especially so that they coincide.

3. The geologic time scale if the record of the major events and changes in earth. Scientists created this in order to keep with the major geographical things happening on earth. Scientists created the geologic time scale using relative dating.

4.  Speciation is the method of formation of new species. Speciation is of 3 types. Type 1 Allopatric Speciation Type 2 Sympatric Speciation.

Sympatric speciation happens when members of a population develop genetic differences that prevent them from reproducing with the parent type. Allopatric speciation is the evolution of species in a population that occupy different geographical areas.

Answer:

The Holographic Principle, proposed by physicist Gerard 't Hooft and further developed by Juan Maldacena, is a fascinating concept in theoretical physics that has sparked significant interest and research. In the context of the AdS/CFT correspondence, it suggests that a gravitational theory in a higher-dimensional space can be mathematically equivalent to a quantum field theory in a lower-dimensional space.

At the heart of the Holographic Principle is the idea that the information and dynamics of a higher-dimensional theory can be fully captured by its boundary, implying that the entire bulk can be "holographically" encoded on the boundary. This concept challenges our conventional understanding of the relationship between space, gravity, and quantum mechanics.

The holographic duality proposed by Maldacena specifically relates a gravitational theory in Anti-de Sitter space (AdS) with a conformal field theory (CFT) in one fewer dimension. In this correspondence, the gravitational theory describes a curved space-time with gravity, while the CFT is a quantum field theory without gravity but living on the boundary of the AdS space. The holographic duality suggests that the two theories are mathematically equivalent and provide equivalent descriptions of the same physical phenomena.

The mathematical foundations of the AdS/CFT correspondence involve advanced concepts from string theory and quantum field theory. String theory postulates that fundamental particles are not point-like entities but rather tiny vibrating strings. By considering these strings propagating in a higher-dimensional space, theorists discovered that they naturally give rise to gravity. The holographic duality emerged as a surprising consequence of studying string theory in the AdS space.

The implications of the Holographic Principle are profound. First and foremost, it suggests a deep connection between gravity and quantum mechanics, two fundamental pillars of modern physics that have been notoriously difficult to reconcile. The holographic duality provides a framework to study strongly interacting quantum systems in terms of gravity, enabling insights into the nature of black holes, the behavior of matter in extreme conditions, and other phenomena that are challenging to analyze using traditional methods.

The Holographic Principle also has potential implications for our understanding of black holes. It proposes that the information that falls into a black hole is not destroyed, as suggested by the Hawking radiation phenomenon, but rather encoded on its event horizon. This idea, known as the "holographic encoding of information," has stirred intense debates and ongoing research in the field of black hole information paradox.

Furthermore, the Holographic Principle challenges our traditional notions of spacetime. It suggests that spacetime, as we perceive it, might emerge as an approximation or an emergent property from a more fundamental description involving quantum information. This notion aligns with the concept of "entanglement entropy," which measures the entanglement between quantum states and has been linked to the geometry of spacetime.

The potential revolutionary impact of the Holographic Principle lies in its potential to provide a unified framework for understanding quantum gravity and resolving long-standing mysteries in theoretical physics. It opens new avenues for studying the nature of black holes, the behavior of matter in extreme conditions, and the fundamental structure of the universe. However, it is important to note that the Holographic Principle is still an area of active research, and many aspects of its implications and applications continue to be explored and refined by physicists.

Answer:

answer a: a large front gear with a small back gear

answer b: a small front gear with a large back gear

Explanation:

just simple gearing ratios

To rotate wheels turn many times with few strokes a large front gear with a small back gear is required and to minimize the force a small gear in the front and the large back gear are required. So, when a large amount of energy is applied the bicycle moves more as compared to less energy applied.

Toothed wheel mounted to a spinning shaft, used as a machine part. With the teeth from one gear engaging the teeth of the other gear, gears work together to transfer and modify rotational movement and tension (turning force) without slipping. The ratios of rotational speeds and shaft torques are constant when a pair of matching gears have teeth that are aligned in circles, or when the gears are serrated wheels. Speed control and torque ratios result from the arrangement of the teeth on non-circular bodies.

Typically, gears are round. Gear teeth's contact surfaces need to be precisely formed to a particular profile in order to transfer movement easily and with a steady speed proportion at every moment.

Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)

Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.

2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.

3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.

The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.

My guess is:  

It's an electromagnet.  A long piece of wire is coiled around an iron core.  Then, when the ends of the wire are connected to the terminals of the battery, electric current flows through the wire, and the magnetic field around the wire makes the iron core a magnet.

Answer:

Energy is found as:

E = 1.987·10⁻¹⁹ J

Explanation:

Energy of a single photon of infrared light can be found by using the following formula:

\(E=hf\)

where

E = in Joules

h = Planck's constant = 6.627×10 ⁻³⁴ J

f = frequency in hertz

It can also be written as:

\(E = \frac{hc}{\lambda}\)

where

c = 2.998×10⁸ ms⁻¹

λ = wavelength

Wavelength is given in the question which is:

λ = 1×10⁻⁶m

Substitute all the values in the Energy formula

\(E = \frac{hc}{\lambda}\\E = \frac{(6.627\cdot10^{-34})(2.998\cdot10^8)}{1\cdot10^{-6}}\\E = 1.987\cdot10^{-19}J\)
