Ball takes around 3.19 seconds to reach ground from a 51-meter cliff, using kinematic equation for vertical motion.

A mathematical formula known as the kinematic equation is used to describe how an object moves when it is subject to forces specifically in terms of its position, velocity, acceleration and time. It links these factors in a way that makes it easier to analyze and forecast how objects will move in a variety of scenarios including free fall, projectile motion and uniformly accelerated linear motion.

\(h = \frac{1}{2}gt^{2}\)

h = height of the cliff = 51 meters

g = acceleration due to gravity =  9.81 m/s²

t = time we want to find.

\(t = \sqrt{\frac{2h}{g} }\)

\(t = \sqrt{\frac{2*51}{9.81} }\)

t ≈ 3.19  seconds

It will take approximately 3.19 seconds for the ball to reach the ground after rolling off a 51-meter tall cliff.

Answer:

3.77202

Explanation:81.9 kg×9.8N/kg÷0.0021 Pa ×(1atm/101325)=3.77202

The pressure exerted between her toes and the ground is 3.77 atm.

The stress at a location within a confined fluid or the perpendicular force per unit area are the two definitions of pressure used in the physical sciences. A 42-pound box with an area of 84 square inches at the bottom will apply pressure on a surface equal to the force divided by the surface area.

Given:

An 81.9 kg person stands on her toes. The surface area of her toes in contact with the ground is only 0.00210 m²,

Calculate the pressure on the toe as shown below,

The pressure on the toe = Force of man / area of toe

The pressure on the toe = mass of man × 9.8 / 0.00210

The pressure on the toe = 81.9 × 9.8 / 0.00210

The pressure on the toe = 802.62 / 0.00210

The pressure on the toe = 382200 N/m²

The pressure on the toe = 382200 / 101325 (1 atm = 101325 N / m²)

The pressure on the toe = 3.77 atm,

To find the length of the ramp, we can use the equation for mechanical advantage (MA), which is:

MA = load / effort

The mechanical advantage of the ramp is 4, which means that for every 4 units of distance the load is moved, the effort required is moved 1 unit of distance. Therefore the effort is 4 times shorter than the load distance.

We know that the load distance is the height of the pyramid, which is 146m. So, we can use this information to find the effort distance.

Effort distance = Load distance / MA

Effort distance = 146m / 4 = 36.5m

So, the ramp would need to be 36.5m long in order to provide a mechanical advantage of 4.

The aforementioned circumstances can result in the production of 0.119 moles of ammonia (NH3).

We must utilize the ideal gas law and the stoichiometry of the balanced chemical equation for the reaction between hydrogen (H2) and nitrogen (N2) to make ammonia in order to determine how many moles of ammonia (NH3) were produced.

Let's begin by formulating the reaction's balanced equation:

3H₂ + N₂ → 2NH₃

We can see from the equation that we produce 2 moles of ammonia for every 3 moles of hydrogen. As a result, the molar ratio of ammonia to hydrogen is 2:3.

We must convert the supplied parameters of 4.0 liters of hydrogen at 50.0 °C and 1.2 atm of pressure into moles in order to use the ideal gas law. The ideal gas law and the molar volume of an ideal gas at standard temperature and pressure (STP) may be combined using the equation shown below:

PV = nRT

Where:

The temperature must first be converted from Celsius to Kelvin:

T(K) = T(°C) + 273.15

T(K) = 50.0°C + 273.15 = 323.15 K

To solve for the number of moles (n), we may now rearrange the ideal gas law equation as follows:

n = PV / RT

n = (1.2 atm) * (4.0 L) / (0.0821 L·atm/(mol·K) * 323.15 K) ≈ 0.179 mol

Since ammonia and hydrogen have a 2:3 molar ratio, we can calculate the amount of ammonia created by multiplying (2/3) * 0.179 mol by 0.119 mol.

As a result, the circumstances allow for the production of 0.119 moles of ammonia.

The estimated rotational speed of the surface of Earth is 1000 miles per hour. The estimated circumference of Earth is 72000 miles. The estimated radius of Earth is approximately 11459.5 miles.

To estimate the rotational speed of the surface of Earth, we can calculate the time difference between Seattle and New York and the distance between them.

The time difference is 11:00 a.m. - 8:00 a.m. = 3 hours.

The distance between Seattle and New York is given as roughly 3000 miles.

Rotational speed = Distance / Time = 3000 miles / 3 hours = 1000 miles per hour.

Therefore, the estimated rotational speed of the surface of Earth is 1000 miles per hour.

To estimate the circumference of Earth, we can use the distance between Seattle and New York and the time difference.

The time difference of 3 hours corresponds to a time zone difference of approximately 1/24th of a full rotation around Earth.

Circumference of Earth = Distance / Time Difference = 3000 miles / (1/24) = 72000 miles.

Therefore, the estimated circumference of Earth is 72000 miles.

To estimate the radius of Earth, we can use the circumference calculated in the previous step and the formula for the circumference of a circle.

Circumference of Earth = 2π × Radius

72000 miles = 2π × Radius

Radius = 72000 miles / (2π) ≈ 11459.5 miles.

Therefore, the estimated radius of Earth is approximately 11459.5 miles.

Mercury's solar day is longer than its solar year, making the statement true.

Mercury's solar day is longer than its solar year, which makes the statement true.

Mercury takes approximately 58.6 Earth days to complete one full rotation on its axis, which is its solar day. In contrast, it takes approximately 88 Earth days for Mercury to complete one orbit around the Sun, which is its solar year. This means that Mercury's solar day is longer than its solar year.

The reason for this is due to a phenomenon called tidal locking. Tidal locking occurs when the gravitational forces between two celestial bodies cause one body to always face the other with the same side. In the case of Mercury, its rotation is tidally locked with its orbit around the Sun. As a result, it takes longer for Mercury to complete one rotation on its axis compared to its orbit around the Sun.

PE = mgh,

where m is the mass of the book, g is the acceleration due to gravity, and h is the height of the book above the floor.

the mass of the book is 1.5 kg

the height is 0.75 m

the acceleration due to gravity is 9.8 m/s²,

we can substitute these values into the formula and solve for the potential energy.

PE = mgh

PE = (1.5 kg) x (9.8 m/s²) x (0.75 m)

PE = 11.025 J

Therefore, the potential energy of the book is 11.025 joules.

The potential energy of an object is defined as the energy that an object possesses due to its position relative to other objects in its surroundings.

In this case, the book has potential energy because it is positioned above the floor, and this position gives it the potential to do work when it falls to the ground.

To calculate the normal force exerted by the seat of the car on the passenger when the car is at the bottom of the depression, we need to consider the forces acting on the passenger.

At the bottom of the depression, the passenger experiences an inward net force directed towards the center of the circular path. This force is provided by the normal force exerted by the seat. To determine the normal force, we need to consider the centripetal force acting on the passenger.

The centripetal force can be calculated using the formula:

F_c = m * a_c

where F_c is the centripetal force, m is the mass of the passenger, and a_c is the centripetal acceleration.

The centripetal acceleration is given by:

a_c = v² / r

where v is the velocity of the car and r is the radius of the circular depression.

Given:

Velocity of the car (v) = 10 m/s

Radius of the depression (r) = 30 m

Mass of the passenger (m) = 60 kg

First, we calculate the centripetal acceleration:

a_c = (10 m/s)² / 30 m = 100 m²/s² / 30 m = 10/3 m/s²

Now, we can calculate the centripetal force:

F_c = (60 kg) * (10/3 m/s²) = 200 N

Since the normal force exerted by the seat is equal to the centripetal force, the normal force is 200 N. Therefore, the normal force exerted by the seat on the 60 kg passenger at the bottom of the depression is 200 N.

The correct option is E, The case that will result in the shortest tidal range is "The Earth Sun and Earth-Moon lines are at an angle of 45° to each other in January".

Tidal range refers to the vertical difference between the high tide and low tide water levels at a given location over a certain period of time, usually over a 24-hour period. The tidal range is determined by various factors, including the gravitational forces of the sun and moon on the Earth, the shape of the coastline, and the depth and configuration of the ocean floor.

The tidal range can vary significantly depending on the location and the phase of the moon. For example, during a new or full moon, the gravitational forces of the sun and moon align, resulting in higher high tides and lower low tides, which results in a larger tidal range. On the other hand, during a quarter moon, the gravitational forces are less intense, resulting in smaller tidal ranges.
