What pathway in the rock cycle might rock take nextv if it is subjected to uplift?

Answer:

0.03 Joules have been converted into other forms of energy as the direct result of the collision.

Explanation:

Let's start studying the conservation of momentum for the system:

\(P_i=P_f\\(0.25\,kg)\,{0.6\,m/s)+(0.5\,kg)\,(0\,m/s)=(0.25\,kg+0.5\,kg)\, v_f \\\\\\ 0.15\,kg\,m/s=0.75\,kg\,\,v_f\\v_f=0.15/0.75\,\,m/s\\v_f=0.2\,\,m/s\)

Now that we know the speed of the newly created object, we can calculate how the final kinetic energy differs from the initial one:

\(K_i=\frac{1}{2} (0.25)\,(0.6)^2+\frac{1}{2} (0.5)\,(0)^2=0.045\,\,J\\ \\K_f=\frac{1}{2} (0.75)\,(0.2)^2=0.015\,\,J\\\)

Then, when we subtract one from the other, we can estimate how much kinetic energy has been converted into other forms of energy in the collision:

0.045 J - 0.015 J = 0.03 J

Answer:

0.45m/s

Explanation:

Given parameters:

Distance = 1.8m

Time  = 4s

Unknown:

Speed of the car  = ?

Solution:

The speed of a body is the distance divided by the time.

       Speed  = \(\frac{distance}{time}\)  

So;

     Speed  = \(\frac{1.8}{4}\)   = 0.45m/s

Answer

  96mph

Explanation:

You are given "144 miles in 90 minutes" and what you need to figure out is "144 km in X hours." To go from 90 min to hours, you can do 90 min * 1hr/60min = 1.5 hrs or 144 km in 1.5 hrs or 144 km per 1.5 hours. 144/1.5 = 96.

The rms speed of a molecule in Mars's atmosphere is 345 m/s.

Mars has an atmosphere composed almost entirely of carbon dioxide, with an average temperature of -63 ∘C.

We know that rms speed of a molecule is denoted by:\(V_{rms} = \sqrt{3RT/M}\)  

Where, R = 8.315 J/mol. K

            T =temperature=-63°C = 210K

            M=molar mass (in kg/mol)

Here, Carbon dioxide is present, so M= \(44*10^{-3} kg/mol\)

Now putting the given values in above equation we get \(V_{rms}\)= 345 m/s.

i.e. The rms speed of a molecule in Mars's atmosphere is 345 m/s.

The net force on the block will be 75N

The question is incomplete that is why we suppose that the force applied on the block is 100N.

Therefore,

                Applied force = 100N

                Friction force = 25N

                Mass of block = 5kg

Since, we know that frictional force acts opposite to the applied force if the block is moving in the horizontal direction.

Then,

                 Net force = Applied force - frictional force

                                  = 100 N- 25N

                                   = 75 N

Hence, the net force acting on the block will be 75N and it will move in the direction of applied force.

The greater the resistance, the greater the area and the greater the speed. The frequency at which air molecules come into contact with the object increases with speed. Air resistance increases as a result.

Answer:

Explanation:

There are three states of matter; solid, liquid and gaseous states.

The solid state of matter has it's particles tightly packed with very restricted  or no movement within the molecule hence the reason for it's definite shape.

The liquid state of matter has it's particles with a free movement (better than solid but not as free as gases) within the molecule hence it's particles are loosely packed within the molecule. Hence, they (liquids) assume the shape of the container in which they are stored and they move freely when released from the container.

The gaseous state of matter has it's particles totally loosely packed as a result of it's particles moving freely and colliding against one another.

Thus, we can use the above descriptions to answer the statements from the question.

1) The atoms in a  ----- are closely packed, but able to slide past each other. Answer: From the description above, it can be deduced that the atoms here are in a solid because the particles within a solid are closely packed.

2) The atoms in a  -------- spread as far apart as possible.

Answer: The atoms here are in gaseous form because, as described earlier, they are loosely packed and  can thus be as far apart as possible.

3) A  ----- has a definite shape and volume.

Answer: As described earlier, a solid substance would have a definite shape and volume because it's particles are tightly packed.

4) The shape of a  ----- can change, but the volume is definite.

Answer: The substance here is a liquid because the particles are free (but not as free as gases) and would have a definite volume but will assume the shape of the any container they are placed in (hence they have an irregular shape).

The density of the cylinder is 14100 kg/m³. The result is obtained by using the formula for density.

The density is the mass of a substance per unit of volume. It can be expressed as

ρ = m/V

Where

A cylinder is measured to have

Find its density in kg/m³!

The radius of the cylinder is

r = ½d

r = ½(3.5)

r = 1.75 inches

r = 1.75 × 2.54 cm

r = 4.4 cm

We find the volume of the cylinder.

V = ⅓ πr²l

V = ⅓ (3.14))(4.4)²(5.6)

V = 113.5 cm³

The density will be

ρ = m/V

ρ = 1600/113.5

ρ = 14.1 g/cm³

Let's convert the unit of density to kg/m³!

ρ = 14.1 × 1/1000 × 1000000/1 kg/m³

ρ = 14100 kg/m³

Hence, the cylinder has the density of 14100 kg/m³.

The charge on a discharging capacitor decreases exponentially with time, and the rate of the decrease is determined by the resistance and capacitance values in the circuit.

The charge on a discharging capacitor decreases exponentially with time according to the following equation:

\(Q(t) = Q0 * e^{-t / (R * C})\)

where Q(t) is the charge on the capacitor at time t, Q0 is the initial charge on the capacitor, R is the resistance in the circuit, C is the capacitance of the capacitor, and e is the mathematical constant known as Euler's number.

The time constant for the discharging process is given by the product of resistance and capacitance,

τ = R * C.

The time constant represents the time it takes for the charge on the capacitor to decrease to approximately 36.8% of its initial value

(i.e.,\(Q(τ) = Q0 * e^{-1} ≈ 0.368 * Q0\)).

Therefore, the charge on a discharging capacitor decreases exponentially with time, and the rate of the decrease is determined by the resistance and capacitance values in the circuit.

Answer:

Acceleration, a = -0.5 m/s²

Explanation:

Given the following data;

Initial velocity = 72 km/h

Final velocity = 18 km/h

Time = 10 seconds

To find the acceleration of the car;

Conversion:

72 km/h to m/s = 72*1000/3600 = 20m/s

18 km/h to m/s = 18*1000/3600 = 5 m/s

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

\(Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}\)

Substituting into the equation;

\(a = \frac{5 - 20}{10}\)

\(a = \frac{-5}{10}\)

Acceleration, a = -0.5 m/s²

Therefore, the car is decelerating.
