A ball which is most likely to topple the bowling pin is: 2. the rubber ball.

The law of conservation of momentum states that the total linear momentum of an isolated (closed) system would always remain constant (the same) with respect to time, unless an external force is applied.

Additionally, the law of conservation of momentum states that the total momentum of two interacting objects in an isolated (closed) system would be the same or remain constant, provided no external force is applied.

In this scenario, we can logically deduce that momentum is conserved in the interaction between the large wooden bowling pin and a ball, but more momentum would be transferred from the rubber ball to the bowling pin, rather than from the putty ball to the rubber ball.

In conclusion, the rubber ball is more likely to topple the bowling pin over because it acts as an external force.

Plates moving at 7.3 cm/year are approximately 5.615 times faster than those moving at 1.3 cm/year.

The speed at which plates move is determined by the relative motion between tectonic plates along their boundaries. To compare the speeds of plates moving at different rates, we can calculate the ratio between their velocities.Let's consider plates moving at 7.3 cm/year and 1.3 cm/year. To find the factor by which the faster plates are moving compared to the slower plates, we divide their velocities:

7.3 cm/year / 1.3 cm/year = 5.615

In other words, for every unit of time, the faster plates cover approximately 5.615 times the distance covered by the slower plates. This difference in speed can have significant implications for geological processes such as the accumulation of strain along plate boundaries, the occurrence of earthquakes, and the formation of mountain ranges. It highlights the dynamic nature of tectonic plate movements and their influence on Earth's geology and surface features.

The force of the man when the piano sides down is 1575N.

The rate of change in velocity is defined as acceleration. This entails a change in speed and direction. When only a change in speed is involved in acceleration: Positive acceleration occurs when an object accelerates. When an object slows down, it experiences negative acceleration. Acceleration is defined as a change in velocity over time.

The rate of change of an object's velocity with respect to time is defined as acceleration. Vector quantities are accelerations. The orientation of an object's acceleration is determined by the orientation of its net force.

Any process in which the velocity changes is referred to as acceleration.

Since the man prevents the piano from accelerating, the force he exerts on it must be equal and opposite to the force of gravity.

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic mass (number of nucleons).

The isotope of an element is denoted by \( X_{Z}^{A} \)

Where; X is the symbol of the element.

A is the atomic mass or number of nucleons.

Z is the atomic number or number of protons.

Hence, an atom with 29 protons and 36 neutrons is an isotope of copper because it has an atomic mass of 65, which corresponds with that of the chemical element known as copper with the symbol, Cu.

Answer: Noise above 70 dB can cause hearing damage

Explanation:

Answer:

The decibel level that starts to have hearing damage is 120 dB.

Explanation:

Water can enter the system from different sources such as air, moisture, or impurities in the materials used.

Even if anhydrous methanol is used, water can still get into the system from various sources. One source is the air, which can carry moisture. The moisture can condense in the system as the air cools, especially in colder environments, such as when refrigeration is used in the system. Another source is impurities in the materials used in the system, such as equipment and piping, which can contain water and release it into the system.

It is essential to prevent water from getting into the system as it can lead to various problems such as corrosion, damage to equipment, and changes in the process conditions, which can affect the product quality. The system should be designed, operated, and maintained to minimize the ingress of water. This can be done by using high-quality materials, controlling the environment, using appropriate procedures, and regularly monitoring and testing the system for water content.

Water can enter the system even if anhydrous methanol is used. Therefore, it is important to prevent water ingress by using appropriate materials, procedures, and monitoring techniques to ensure the quality and safety of the process.

The woman stops 1.837 meters (vertically) above the bottom of the hill when she stops.

Given that the weight of the woman riding a bicycle is 62 kg and her speed at the bottom of the hill is 6 m/s.

The problem requires us to calculate the vertical height above the bottom of the hill where she stops.

Let's assume that the potential energy gained by the woman and the bike equals the kinetic energy lost as the bike decelerates to a stop.

The gravitational potential energy formula can be used to calculate the potential energy.

The formula is;

Potential energy = mass × gravity × height

PE = mgh

Where

m = 62 kg,

g = 9.8 m/s²

h is the height above the bottom of the hill.

Substituting the values in the formula;

PE = 62 × 9.8 × h

PE = 607.6h

The potential energy calculated is equal to the kinetic energy lost at the point where the bike comes to a stop.

Thus, we can use the kinetic energy formula to calculate the kinetic energy of the bike.

The formula is;

Kinetic energy = 0.5 × mass × velocity²

KE = 0.5 × 62 × 6²

KE = 1116

The kinetic energy of the bike equals the potential energy gained by the woman and the bike as the bike travels up the hill.

Therefore;

PE = KE

607.6h = 1116

h = 1116/607.6

h = 1.837

The woman stops 1.837 m above the bottom of the hill when she coasts to a stop.

A truck accelerating at 0.0083 meters/second2 covers a distance of 5.8 ×\(10^4\) meters. If the truck's mass is 7,000 kilograms, the work done to reach this distance is 3.3× \(10^6\) joules.

The correct answer is option E.

To calculate the work done by the truck to cover a distance of 5.8 × \(10^4\)meters, we need to use the equation for work:

Work = Force × Distance

In this case, the force can be calculated using Newton's second law:

Force = mass × acceleration

Where:

Acceleration (a) = \(0.0083 meters/second^2\)

Distance (d) = 5.8 ×\(10^4\) meters

Mass (m) = 7,000 kilograms

First, let's calculate the force exerted by the truck:

Force = mass × acceleration = (7,000 kg) ×\((0.0083 meters/second^2)\)= 57.1 Newtons

Next, we can calculate the work done:

Work = Force × Distance = (57.1 N) × (5.8 × 10^4 meters) = 3.3158 × \(10^6\)joules

Rounded to the nearest significant figure, the work done by the truck is approximately 3.3 × \(10^6\) joules.

The height of the building is   13.180meters.

Since, we are given the length of window as 1.30m and we are also given the time duration the ball takes to pass the window which is 0.127sec.

For the window:

Length of window=1.30m--------(eq1)

Therefore, we apply newton second law of equation

=>S = ut+(1/2)at²

Therefore, putting the values on above equation, we get

=>1.30=u×0.127+(1/2×9.8)×(0.127)²

=>1.30-(4.9×0.127×0.127)=u×0.127

=>1.30-0.07=u×0.127

=>u×0.127=1.220

=>u=10.15m/sec.

Applying newton first equation of motion at the bottom of window

=>v=u+at

=>v=10.15+9.8×0.127

=>v=10.15+1.2446

=>v=11.3946

Now when ball reaches the bottom of the building, its velocity will be zero and the final velocity at the bottom of window will act as initial velocity for finding the distance after the bottom part of window

For bottom of the window

So, we apply newton third equation of motion for finding the distance from the bottom of window

=>v²-u²=2aS

=>0-(11.3946)²=2×9.8×S

=>S=129.836/19.6

=>S=6.624meters-------(eq2)

Now, for finding  the distance above the window ,we have final velocity of ball the top of the window, and initially ball is dropped so, we apply newton third law of motion for the top part of the building

For above of the window

=>v²-u²=2aS

=>(10.15)²-0=2×9.8×S

=>S=5.256m-------(eq3)

Combining eq1,eq2 and eq3,we get

=1.30+6.624+5.256=13.180m

The weight of the board influences the amount of effort required to move it because if it were too heavy, it would just sink, and if it were too light, it would simply float away.

The gravitational pull of a second, significantly bigger object, like the Earth or Moon, on a first object is known as weight. According to the universal law of gravity, any two objects will gravitate toward one another due to their masses with a force that is inversely proportional to the square of the distance between them and precisely proportional to the product of their masses. The source of weight is this law. Because of this, larger objects naturally weigh more when placed in the same location. However, the further an object is from the Earth, the less weight it has. An object's weight at the South Pole is somewhat higher than its weight at the North Pole because the Earth's polar radius is slightly less than its equatorial radius.
