The combination of low oxygen levels in the ocean and low carbon dioxide in the atmosphere led to cooling temperatures and the Late Devonian extinction, 380 million years ago. Many ocean dwellers went extinct, including trilobites. In contrast, tetrapods fared best since they were transitioning from sea to land and could survive in both regions.

The tetrapods are characteristized by the possession of muscles and skeleton which aids support and movement respectively.

The tetrapods are referred to as vertebrates ( those animals with backbones) which have two pairs of limbs. That is, they have four different limbs

The energy that an object possesses as a result of its motion or position is known as mechanical energy.

Mechanical energy is the energy that an object holds as a result of its motion or position. Potential energy and kinetic energy are two different kinds of mechanical energy (stored energy of position). In the physical sciences, mechanical energy is the sum of kinetic and potential energy. Mechanical energy is constant in an isolated system when only conservative forces are at work on it, according to the mechanical energy conservation principle.

A mass-spring system is, to put it simply, a spring system with a block suspended from or affixed to the spring's free end. Typically, the period of any harmonically moving object may be calculated using the spring-mass system.

The mechanical energy is equal to the potential energy of the spring at the maximum displacement (since v=0 at this point).

It is discovered that the capacitor’s potential difference increases to 4.0 V in one second.

There is a potential difference (p.d.) between the plates of a capacitor when it is completely charged, and the larger the area of the plates and/or the smaller the distance between them (known as separation), the greater the charge that the capacitor can carry and the greater the capacitance.

Divide the resistance present in the circuit by the current flow rate.

The resulting number, expressed in volts, is the potential difference. Ohm's Law, or V = IR, is the name of this equation.

With several parallel capacitors, the potential difference is the same, but the charge increases. Similar to adding resistance in series, paralleling capacitors increases effective capacitance.

Effective capacitance is calculated as effective capacitance = capacitance 1 + capacitance 2.

The downward acceleration after release is 9.8 m/s^2.

What is the universal law of gravitation, or NLG?

Every particle of matter in the universe is drawn to every other particle by a force that varies directly with their combined masses and inversely with their distance from one another.

Whether an object is moving or at rest, gravity still exerts its force on it.

In the given case, the general equation is as follows:

s = s₀+v₀t+1/2g[tex]t^{2}[/tex]

where

s is referred to as position at time t,

s₀ is referred to as the initial position,

v₀ is referred to as the initial velocity,

g is referred to as the acceleration of gravity and

t is referred to as the elapsed time.

When the object leaves your hand, we would typically say that time is (t)=0.

An object initial velocity is increased when it is thrown, whereas it would be zero if it were simply dropped.

However, once it is out of your hand, gravity accelerates at the same rate in both directions. As a result, the downward acceleration is 9.8 meters per second squared.

The average speed in m/s, given the data is 820.80 m/s

Speed is the distance travelled per unit. Mathematically, it can be expressed as:

Speed = distance / time

This is the total distance travelled divided by the total time taken to cover the distance.

Average speed = total distance / total time

Speed = distance / time

684 = 446000 / time

Cross multiply

684 × time = 446000

Divide both side by 684

Time = 446000 / 684

Time to fly away = 652.05 s

Speed = distance / time

1026 = 446000 / time

Cross multiply

1026 × time = 446000

Divide both side by 1026

Time = 446000 / 1026

Time to return = 434.70 s

The average speed can be obtained as follow:

Average speed = total distance / total time

Average speed = 892000 / 1086.75

Average speed = 820.80 m/s

From the free body diagram of the rigid beam system and the guy wire attached, we can say that;

Taking moments about point C gives;

∑Mc = 0; -(2000 * 5) + (F_BA * cos 30 * 10) = 0

In order to provide a low-friction support surface for rotating or sliding surfaces, friction bearings are composed of a stationary, non-moving bearing surface, such as machined metal or a pressed-in bushing.

Lubricating oil is frequently used in friction bearings to isolate the moving part from the mated non-moving bearing surface. An antifriction bearing uses rolling parts connected by inner and outer rings to absorb the radial forces acting on the rotor.

The final velocity of the car starting from rest with an acceleration of 5 u for 30 seconds is 150 m/s.

Newton gave three laws of motion which can be utilized to find the velocity, acceleration and displacement of a body. These law are only applicable for constant acceleration.

Acceleration is the physical quantity which represents change in velocity per unit time.

In simpler words it can be said as the increment or decrement in the velocity per second.

Given:

Total time taken 30 seconds

Acceleration of the car = 5 u

Initial velocity of the car = 0m/s

Here we have to find the velocity of the car after 30 seconds.

We already know all the basic values that are used for finding the value of final velocity.

Using Newton's first law of motion we have:

v = u + a × t

Where,

v is the final velocity of the car

u is the initial velocity of the car

a is the acceleration of the car

t is the total time taken to complete the displacement.

Substituting given values in Newton's first law of motion we get

Final velocity = 0 + 5 × 30

Final velocity = 0 + 150

Final velocity = 150 m/s

Therefore, the final velocity of the car starting from rest with an acceleration of 5 u for 30 seconds is 150 m/s

The most immediate, but necessarily limited, source of energy for reformation of ATP in muscle cells is creatine phosphate. When ATP is used for energy by the cells, it is broken down into ADP and inorganic phosphate. This process is reversible, but it requires energy to reform ATP from ADP and inorganic phosphate. The primary source of this energy is creatine phosphate, which donates a phosphate group to ADP to form ATP.

This process is called phosphocreatine resynthesis and it occurs in the mitochondria of muscle cells. Phosphocreatine is synthesized from creatine and ATP in a reaction that requires the enzyme creatine kinase. This reaction is irreversible, meaning that the synthesis of phosphocreatine from creatine and ATP cannot be used to generate ATP.

The amount of ATP that can be generated from phosphocreatine resynthesis is limited by the amount of creatine phosphate available in the muscle cells. Creatine phosphate is synthesized in the liver from creatine and ATP. It is then transported to the muscle cells where it is used for phosphocreatine resynthesis. The synthesis of creatine phosphate in the liver is a slow process and the amount of creatine phosphate in the muscle cells is limited.

The most immediate source of energy for reformation of ATP in muscle cells is therefore creatine phosphate. This source of energy is limited, however, and other sources of energy must be used to maintain ATP levels in the cells.

The gravitational force applied on the object or weight of the object is equal to 1920 N.

What is weight?

The force exerted on an object by gravity is known as the weight of the object in science and engineering. The gravitational force acting on the any object is referred to as weight in several common textbooks. Some people refer to weight as a scalar quantity that measures the gravitational force's strength. Others define it as the strength of the force that mechanisms that counteract the effects of gravity impose on a body.

In order to calculate the object's weight we just needed to multiply its mass with the given gravitational acceleration. Then after inserting the values for m and g we can obtain the solution.

So, we get equation

F = (-5.2,2.3), where all components are in newtons. if a vector's direction is measured counterclockwise from the positive x-axis the angle (in degrees from 0-360) does f make 90.41.

A vector specifies the magnitude and direction of the quantity it is related to. Acceleration is the result of a velocity vector that changes over time. A body can be rotated by two or more forces, but the results of the rotation will vary.

A unit vector is defined as a vector with a specific direction and a magnitude of one unit.

F cosθ= -5.2,

F sinθ= 2.3

Please be aware that because the x component is negative, vector F lies in the second quadrant (plot points of F in graph to check)

thus, tanθ = 2.3/5.2
