To determine the mass of granite, we must first understand the definition of density. Density is defined as the amount of matter present in a substance per unit volume.

We use the formula: density = mass/volume to calculate the mass of a substance given its density and volume. To calculate the mass of 54.3 m³ of granite, we use the following steps:

Given Density of granite = 2700 kg/m³Given volume of granite = 54.3 m³Let us substitute the values in the formula of density:density = mass/volume Solving for mass, we get:mass = density × volume Substitute the given values of density and volume into the formula:mass = 2700 kg/m³ × 54.3 m³

The m³ unit in the volume cancels out, leaving us with kg as the unit for mass.

We then solve the equation to get the mass:mass = 146,610 kg

Therefore, the mass of 54.3 m³ of granite is 146,610 kg.

Zoologists studying the ecology of the Serengeti Plain estimate that the average adult cheetah can run 100 km/h and the average springbok can run 65 km/h. If the animals run along the same straight line, start at the same time, are each assumed to have constant acceleration, and reach top speed in 4 s then the cheetah must be within 2475 meters of the springbok at the start of the chase to catch it in 15 seconds.

Let's start by assuming that both the cheetah and the springbok accelerate uniformly from rest to their respective top speeds in 4 seconds. We can then use the following kinematic equations to solve for the distance between the two animals at the start of the chase

For the cheetah

vc = ac t

dc = (1/2) ac \(t^{2}\)

For the springbok

vs = as t

ds = (1/2) as \(t^{2}\)

Where vc and vs are the velocities of the cheetah and springbok, respectively, at time t, ac and as are their respective accelerations, dc and ds are their respective distances traveled in time t.

We are given that the cheetah's top speed is 100 km/h and the springbok's top speed is 65 km/h. We convert these to m/s and then use the fact that they reach top speed in 4 seconds to solve for their accelerations

ac = vc / t = 100 km/h / 3.6 s/h / 4 s = 6.94 m/\(s^{2}\)

as = vs / t = 65 km/h / 3.6 s/h / 4 s = 4.51 m/\(s^{2}\)

Now we can solve for the distance between the two animals at the start of the chase using the given time of 15 seconds

d = d_c - d_s

d = (1/2) ac \(t^{2}\) - (1/2) a_s \(t^{2}\)

d = (1/2) (ac - as) \(t^{2}\)

d = (1/2) (6.94 m/\(s^{2}\) - 4.51 m/\(s^{2}\)) \((15s)^{2}\)

d = 2475 m

Therefore, the cheetah must be within 2475 meters of the springbok at the start of the chase to catch it in 15 seconds.

The kinetic energy of the object at t=1.0s is 7.2 J.

The speed of the object at t=2.0s is 19.

The work done on the object between t=1.0s and t=2.0s is 17.8 J.

What is kinetic energy?

The kinetic energy of an object is given by the equation KE = (1/2)mv², where m is the mass of the object and v is its speed. At t=1.0s, the mass of the object is 0.40 kg and its speed is 6.0 m/s. Therefore, the kinetic energy of the object at t=1.0s is:

KE = (1/2)mv² = (1/2)(0.40 kg)(6.0 m/s)² = 7.2 J

Therefore, the kinetic energy of the object at t=1.0s is 7.2 J.

What is speed of object?

We can use the conservation of energy principle to determine the speed of the object at t=2.0s. The kinetic energy of the object at t=1.0s is equal to its potential energy at t=2.0s (assuming negligible air resistance), so we can set the two equal to each other:

KE(1.0s) = PE(2.0s)

(1/2)mv² = mgh

where h is the height the object falls during the time interval from t=1.0s to t=2.0s. Since the object is in free fall, we can use the equation h = (1/2)gt², where g is the acceleration due to gravity (9.81 m/s²). Therefore, we have:

h = (1/2)gt² = (1/2)(9.81 m/s²)(2.0 s)² = 19.62 m

Substituting this into the equation above and solving for v, we get:

v = √(2gh) = √(2(9.81 m/s²)(19.62 m)) = 19.62 m/s

Therefore, the speed of the object at t=2.0s is 19.62 m/s.

What is work?

The work done on the object between t=1.0s and t=2.0s is equal to the change in its kinetic energy. We know that the kinetic energy of the object at t=2.0s is 25 J, and we calculated that its kinetic energy at t=1.0s is 7.2 J. Therefore, the change in kinetic energy is:

ΔKE = KE(2.0s) - KE(1.0s) = 25 J - 7.2 J = 17.8 J

Therefore, the work done on the object between t=1.0s and t=2.0s is 17.8 J.

Strong storms and hurricanes are the consequences of how the Earth is heated by the sun.

The upper troposphere becomes warmer as the lower stratosphere warms. When the troposphere and the planet's surface are at opposite temperatures, significant updrafts result, which intensifies storms and hurricanes. Updrafts and storm power are diminished during the height of the 11-year solar cycle.

Troposphere, stratosphere, mesosphere, and thermosphere are the layers of the atmosphere. The stratosphere, which contains the ozone layer, is the part of the Earth's atmosphere that is most affected by the sun. The stratosphere, which is where weather happens, is followed by the troposphere.

The order from first to last is: solid sphere, hoop, and disk. The order in which the objects reach the bottom of the inclined plane depends on their moments of inertia and how mass is distributed around their axes of rotation.

The solid sphere will reach the bottom first. Due to its mass distribution, it has the lowest moment of inertia and therefore rolls down the inclined plane more easily.

Next, the hoop will reach the bottom. Although it has a larger moment of inertia than the solid sphere, its mass distribution allows it to roll more easily than the disk.

Lastly, the disk will reach the bottom last. It has the largest moment of inertia among the three objects due to its mass being distributed farther from its axis of rotation.

From the ground, a ball is hurled straight up. A 2-m-high window is passed by it. The ball's starting velocity is 4.82 m/s because the bottom of the window is 7.5 metres above the ground.

Level ground refers to the lowest level of a structure when the majority of its height is exposed above the ground level of the nearby street or riverwalk. The floor that is level with the ground is referred to as the first floor in American English, followed by the floor that is above it and so on. The term "Ground Level" refers to the height of the main construction entrance to the structure or building.

Walking, slipping, tripping, transfers (such as getting up from a chair or bed), falling from furniture (such as a bed or sofa), picking something up off the ground, and standing tasks were all considered to be ground level activities (e.g., washing dishes).

We can employ the kinematic equation to get the ball's starting velocity:

h = vi * t + 0.5 * a * t^2

where an is the acceleration brought on by gravity (-9.8 m/s2), vi is the initial velocity, t is the time (1.3 s), and h is the window's height (2 m).

Rearranging the equation to solve for vi:

vi = sqrt(2 * a * h / t^2)

Substituting the values:

vi = sqrt(2 * (-9.8) * 2 / 1.3^2)

= sqrt(39.2 / 1.69)

= sqrt(23.18)

= 4.82 m/s

Therefore, the ball's initial velocity is roughly 4.82 m/s.

Explanation:

Below 0 degree C (Celsius), water is frozen means it is in the form of ice. After 0 degree, once we keep it in room temperature, the ice starts becoming liquid (water), and once we heat water, after 100 degree C (Celsius) water starts boiling and thus starts entering gaseous state.

A physical property of some energies that correspond to the height of wave peaks is called: Amplitude.

In physics, the word "amplitude" describes the greatest degree of a change or oscillation, such as a wave or signal. It serves as a gauge for the size of the deviation from rest in terms of change or displacement. It merely symbolizes the height or power of a wave or signal. The loudness of the sound wave is inversely proportional to its amplitude in sound. It is equivalent to the light wave's intensity in terms of light.

When asked what amplitude means, the answer is that it is an energy measurement used when describing waves. A wave is a pulse of energy that moves across a medium or, in the case of electromagnetic radiation, through empty space. Amplitude is defined as a measurement of energy transferred by a wave; the more energy put into a wave, the greater the amplitude. When asked what the amplitude of a wave is, the response will vary depending on the type of wave.
