Explanation:

It’s in the definition of biosphere. “Bio” means “life,” so “biosphere” is that portion of the Earth capable of supporting life.

Answer:

0.1 KM/S

Explanation:

First, looking at the question we can say a few things: distance = speed/time. First we will change the 72 KM/HR to ? KM/S (seconds). To change the units fo the speed to seconds, we need to find how many seconds are in an hour which is 3600) then we have 72 KM/3600S and we will divide 3600 by 5 to get 720 which is what we will divide 3600 by to get to 5 seconds and what we will divide 72 by to get your speed in kilometers for your answer. 3600/720 = 5 seconds, and 72/720 is equal to 0.1. To format your answer, you would get 0.1 KM/S (kilometers/seconds)

If your teacher won't accept that answer or you want to change the unit of measurement for speed, you can also find out how many feet/miles a kilometer is and then multiply 0.1 times that value and then you'd have ? ft/s or mi/s.

Answer:

Energy = 6400000 Joules

Explanation:

Given the following data;

Mass = 100kg

Radius of earth = 6400 km

To find the amount of energy required by the object to escape the velocity of the earth, we would apply the Law of Conservation of Energy.

This law states that energy cannot be destroyed but can only be converted or transformed from one form to another. Therefore, the sum of the initial kinetic energy and potential energy is equal to the sum of the final kinetic energy and potential energy.

Mathematically, it is given by the formula;

Ki + Ui = Kf + Uf .......equation 1

Where;

Ki and Kf are the initial and final kinetic energy respectively.

Ui and Uf are the initial and final potential energy respectively.

At the earth surface, potential energy with respect to the radius of the earth is given by the formula;

\( Ui = - \frac {GM}{R} \) ......equation 2.

Also, at the earth surface, kinetic energy is given by the formula;

\( K.E = \frac{1}{2}MV^{2}\) .......equation 3.

After escaping the earth, the object wouldn't have both kinetic and potential energy; Kf = Uf = 0

Substituting eqn 2 & 3 into eqn 1, we have;

\( \frac{1}{2}MV^{2} - \frac {GM}{R} = 0 \)

\( \frac{1}{2}MV^{2} = \frac {GM}{R} \)

Making "V" the subject of formula;

\( RMV^{2} = 2GM \)

\( V^{2} = \frac {2GM}{RM} \)

\( V^{2} = \frac {2G}{R} \)

Therefore, energy = gmR

Energy = 10 * 100 * 6400

Energy = 6400000 Joules

The rate at which the current though a 0.478-h coil is changing if an emf of 0.157 v is induced across the coil is 0.329 A/s.

According to Faraday's law of electromagnetic induction, a voltage is induced across a conductor that is exposed to a changing magnetic field. The magnitude of the induced emf is directly proportional to the rate of change of the magnetic field. The equation for this relationship is:ε = -N(dΦ/dt), where ε is the induced emf, N is the number of turns in the coil, and (dΦ/dt) is the rate of change of the magnetic flux through the coil.

In this case, the induced emf is given as 0.157 V. The number of turns in the coil is not given, but it is not necessary to know it in order to find the rate of change of the current. Therefore, the equation can be rewritten as:(dI/dt) = ε / L, where L is the inductance of the coil.

Substituting the given values gives:(dI/dt) = 0.157 / 0.478 = 0.329 A/s

Therefore, the rate at which the current through the 0.478 H coil is changing is 0.329 A/s.

The temperature of the coffee at t = 1 minute is approximately 53.38 degrees Fahrenheit.

To find the temperature of the coffee at t = 1 minute, we need to substitute t = 1 into the temperature function r(t) and evaluate it.

Given the temperature model:

r(t) = 55e^(-0.03t^2)

Substituting t = 1 into the equation:

r(1) = 5e^(-0.03(1)^2)

= 55e^(-0.03)

Using a calculator to evaluate e^(-0.03), we find that it is approximately 0.97045.

Now, substitute this value back into the equation:

r(1) ≈ 55 * 0.97045

≈ 53.37775

Therefore, the temperature of the coffee at t = 1 minute is approximately 53.38 degrees Fahrenheit.

Answer:

Negative acceleration occurs when the acceleration vector points to the left.

1. Object slowing down in the positive direction.

2. Object speeding up in the  negative direction.

Following six statements:

1. T

2. F

3. T

4. T

5. F

6. T

Check direction of acceleration vector.

The object will accelerate at a rate of 195.0 cm/s^2 when released from the spring.

To find the acceleration of the object when released from the spring, we can use the equation:

F = ma, where F is the force exerted by the spring, and a is the acceleration of the object.

The force exerted by the spring can be found using Hooke's law:

F = kx, where k is the spring constant, and x is the displacement of the spring from its equilibrium position.

In this case, k = 30.0 N/cm and x = 13.0 cm. Converting to SI units, we get:

k = 300 N/m and x = 0.13 m.

Substituting these values into the equation for the force exerted by the spring, we get:

F = kx = 300 N/m x 0.13 m = 39 N.

Substituting the force and the mass of the object (0.2 kg) into the equation for acceleration, we get:

a = F/m = 39 N / 0.2 kg = 195.0 m/s^2.

Converting to centimeters per second squared, we get:

a = 195.0 m/s^2 x 100 cm/m = 19500 cm/s^2 = 195.0 cm/s^2.

Earth's magnetic field  causes cosmic radiation to be deflected around Earth.

Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun. The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.

The magnitude of Earth's magnetic field at its surface ranges from 25 to 65 μT (0.25 to 0.65 G). As an approximation, it is represented by a field of a magnetic dipole currently tilted at an angle of about 11° with respect to Earth's rotational axis, as if there were an enormous bar magnet placed at that angle through the center of Earth.

Compared to the inertia of a 0.10-kilogram steel ball, the inertia of a 0.20-kilogram Styrofoam ball is: b) twice as great

Inertia is directly proportional to an object's mass. Since the Styrofoam ball has twice the mass of the steel ball (0.20 kg vs 0.10 kg), its inertia is also twice as great.

Inertia is the tendency of an object to resist changes in its state of motion. It is one of the fundamental principles of physics and is closely related to the concept of mass.

According to Newton's first law of motion, an object at rest will remain at rest, and an object in motion will continue in motion at a constant velocity, unless acted upon by an external force. This is due to the object's inertia. The greater an object's mass, the greater its inertia, and the more difficult it is to change its motion.

Inertia can be observed in everyday situations, such as when a heavy object is difficult to move or when a moving object continues to move in a straight line unless acted upon by an external force. Inertia is also important in the design of vehicles, where engineers must account for the inertia of the vehicle and its occupants in order to ensure that it can stop or change direction safely.

The force of 30.5 N applied tangentially at the rim of the bicycle wheel with a mass of 44.6 kg and a radius of 0.260 m will result in an acceleration of approximately 0.687 m/s².

The torque, or turning force, applied to the bicycle wheel is equal to the force applied at the rim multiplied by the radius of the wheel, according to the equation τ = Fr, where τ is the torque, F is the force, and r is the radius. In this case, F = 30.5 N and r = 0.260 m.

The moment of inertia, which measures the resistance of the wheel to rotational motion, is given by the equation I = ½mr², where m is the mass of the wheel and r is the radius. In this case, m = 44.6 kg and r = 0.260 m.

Using the torque and moment of inertia, we can apply Newton's second law for rotational motion, which states that τ = Iα, where α is the angular acceleration. Substituting the values we have, we get Fr = ½mr²α.

Rearranging the equation to solve for α, we get α = (2Fr) / (mr²). Plugging in the given values for F, m, and r, we can calculate α as follows:

α = (2 * 30.5 N * 0.260 m) / (44.6 kg * (0.260 m)²)

α ≈ 0.687 m/s²

Therefore, the acceleration of the bicycle wheel's rotation due to the applied force is approximately 0.687 m/s².

Explanation:

The angular momentum of the mother around the center of the carousel is 263.84 kg·m²/s.

Angular momentum is a measure of rotation and is defined as the product of the moment of inertia and angular velocity. In this case, we need to calculate the angular momentum of the mother around the center of the carousel.

The angular momentum formula is:

L = Iω

where L is angular momentum, I is the moment of inertia and ω is angular velocity.

To calculate the moment of inertia, we need to know the mass of the object and its distance from the axis of rotation. The moment of inertia of a point of mass rotated along a distance r about an axis is given by:

I = mr²

where m is the mass and r is the distance from the axis of rotation.

In this case, the mass of the mother is 57 kg and the distance from the center of the carousel is 2.8 m. Therefore, the mother's moment of inertia is:

I = (57 kg) × (2.

8 m)² = 439.04 kg m²

The given angular velocity of 4.6 m/s.

Now L = Iω:

L = (439.04 kg m²) × (4.

6 m/s) = 2018.144 kg·m²/s ≈ 2018.14 kg·m²/s

Therefore, the angular momentum of the mother around the center of the carousel is approximately 2018.14 kg ·m²/s.

The angular momentum of the mom around the center of the carousel is 263.84 kg·m²/s.

The energy consumption per hour of the heater is 9 kJ/hour and the energy consumption per hour of the electric motor is 3 kJ/hour.

Let's denote the energy consumption per hour of the heater as "h" and the energy consumption per hour of the electric motor as "m".

From the first piece of information, we can set up the equation:

2h + 4m = 25 (equation 1)

Similarly, from the second piece of information, we can set up another equation:

3h + 2m = 18 (equation 2)

We now have two equations with two unknowns, which we can solve using algebraic methods. Multiplying equation 2 by 2 and subtracting it from equation 1 multiplied by 3, we get:

(3h + 6m) - 2(3h + 2m) = 25(3) - 18(2)

The main cause of melting along subduction zones is the d. release of water from the subducting plate.

Subduction zones are areas where one tectonic plate moves beneath another, causing the denser plate to sink into the mantle. This process generates a significant amount of heat, which contributes to the melting of rocks in the mantle lithosphere.
As the subducting plate moves deeper into the mantle, it experiences increasing pressure and temperature. The minerals within the subducting plate contain water, which is released as the plate is subjected to these extreme conditions. This released water reduces the melting point of the surrounding mantle rocks, causing them to partially melt.

This partial melting creates magma, which can rise through the mantle lithosphere and eventually reach the Earth's surface, resulting in volcanic activity. The release of water from the subducting plate, therefore, plays a crucial role in generating the magma that leads to volcanic eruptions along subduction zones.
In summary, the main cause of melting along subduction zones is the d. release of water from the subducting plate, which lowers the melting point of surrounding mantle rocks and generates magma. This magma can rise through the mantle lithosphere, causing volcanic activity in these regions.

The main cause of melting along subduction zones is primarily the release of water from the subducting plate (option d). When the oceanic lithosphere subducts, it carries with it water that has been trapped in the minerals of the crust and upper mantle. This water lowers the melting temperature of the surrounding rocks, causing them to melt and form magma. This is termed 'flux melting'.

To find the average force acting on the catcher's hand, we can use the impulse-momentum principle, which states that the change in momentum of an object is equal to the force applied multiplied by the time it is applied.

The momentum of the baseball before catching it can be calculated as: initial momentum = mass * initial velocity. p_initial = 0.206 kg * 18 m/s. After catching the ball, the momentum becomes zero since the ball comes to rest. Therefore, the change in momentum is: Δp = 0 - p_initial = -p_initial. Now, we need to convert the distance moved by the glove to meters: distance = 4.14 cm = 4.14/100 m. The average force can be calculated using the formula: average force = Δp / time. Since we don't have the time information in this problem, we can't directly calculate the average force. However, we can find the time using the distance and the initial velocity: time = distance / initial velocity. Substituting the values, we get: time = (4.14/100 m) / 18 m/s. Now, we can calculate the average force: average force = (-p_initial) / time. Make sure to include the appropriate units in your calculations.
