The average speed is 30 m / sec, or 180 meters divide by 6 seconds. The average speed is 10 meters per second (60 meters divided by 6 seconds). Displacement / time is the definition of average velocity.

Average speed is determined by dividing distances you traveled even by total time, whereas average velocity is determined by divide your displace (a vector pointing form your original position to your end position) by the whole time.

Although some individuals may believe that average pace and mean velocity are simply two different labels for the same amount, average pace depends on both distance and displacement. The average pace will be higher than the typical velocity if an object reverses direction while traveling.

(a) The location of the final image beyond the converging lens is 12.67 cm.

(b) The magnification of the final image is -0.82, indicating that it is inverted with respect to the object.

To find the location of the final image, we can use the lens formula for thin lenses, which is given by 1/f = 1/v - 1/u, where f is the focal length, v is the image distance, and u is the object distance.

For the diverging lens, u = -27 cm (since the object is in front of the lens), and f = -17 cm (negative for diverging lens). Using the lens formula, we find v1 = -153 cm.

For the converging lens, the object distance is -11 cm (since it is behind the diverging lens), and f = 17 cm. Using the lens formula again, we find v2 = 12.67 cm.

The magnification of the final image can be calculated using the formula magnification = v2/v1, which gives us -0.82. The negative sign indicates that the image is inverted with respect to the object.

Newton's second law allows finding the answer for the force that attracts the body is 127.4N

Newton's second law indicates that the force that is the interaction between two bodies is directly proportional to the product of the mass and the acceleration.

            F = m a

Where the bold letters indicate vectors, F is the force, m the mass, and the acceleration of the body.

When a body is close to the Earth there is an interaction between the body and the planet, we call this interaction weight, it is given by the relationship

           W = m g

Where W is the force called weight, m ​​the mass of the body and g the acceleration of the body, which in this case is called the gravity acceleration   (g = 9.8 m / s²)

They indicate that the mass of the body is m = 13 kg, let's calculate the weight

           W = 13  9.8

           W = 127.4 N

Answer:

Nuclear power is presently a sustainable energy source, but could become completely renewable if the source of uranium changed from mined ore to seawater. Since U extracted is continuously replenished through geologic processes, nuclear would become as endless as solar.

Answer:

1.2 A

Explanation:

From the diagram attached, The three resistors are parallel because the each ends of the resistors are connected together. Since they are in parallel, the voltage across each resistor is the same. The voltage source connected in parallel to the resistors is 60 V. Therefore the voltage across the 50 Ω resistor is 60 V. Using ohm law:

Voltage (V) = Current (I) × Resistance (R)

V = IR

I = V/R

I = 60 V/ 50 Ω

I = 1.2 A

The current in the 50 Ω resistor is 1.2 A

The characteristics of the thermistors allow to design an experiment to analyze the dependence of resistance with temperature;

      1) We set up the circuit

      2) We look for the current of the circuit and we keep it fixed.

      3) We look for the thermistor resistances for each temperature.

      4) Plot Resistance versus Temperature.

A Thermitor is an element whose resistance changes with temperature, for example a platinum resistance.

An experiment that we can carry out to measure is to set up the attached circuit where we have:

Let's start by looking for the current in the circuit.

In thermistors, the resistance for room temperature is given, so if we measure the voltage across the fixed resistor, we can shrink the voltage across the thermistor.

           \(V_{source} = V_R + V_{therm} \\V_{therm} = V_{source} - V_R \\ i = \frac{V_{therm} }{R_{therm}}\)

This current remains fixed, since the fixed resistance is greater than the resistance of the thermistor throughout the range.

Second step.

Now we can change the temperature that is measured in the thermometer, for each temperature the voltage in the fixed resistance is measured, the resistance in the thermistor is calculated.

        \(R_{therm} = \frac{V_{source} - V_R}{i}\)  

Third step.

We end with a graph of resistance versus temperature of the curve obtained, it is possible to understand the behavior of the resistance of the thermistor with temperature.

In conclusion with the characteristics of thermistors we can design an experiment to analyze the dependence of resistance with temperature:

      1) We set up the circuit

      2) We look for the current of the circuit and we keep it fixed.

      3) We look for the thermistor resistances for each temperature.

The increase in internal energy of the tie and spike is approximately 1.12 Joules.

The initial kinetic energy of the spike is:

K_i = (1/2) * m * v^2

K_i = (1/2) * 0.60 kg * (1.8 m/s)^2

K_i = 1.94 J

The amount of kinetic energy that is absorbed as internal energy is:

K_absorbed = 0.578 * K_i

K_absorbed = 0.578 * 1.94 J

K_absorbed = 1.12 J

Thus,the value is 1.12 Joules.

Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.

Kinetic energy is the energy of motion, observable as the movement of an object or subatomic particle. Every moving object and particle have kinetic energy. A person walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field are all examples of kinetic energy at work.

The net force on the sled is 400 N.

The net force on the sled is the sum of all the forces acting on the sled. In this case, the only forces acting on the sled are the horizontal force of 200 N applied by the athlete and the force of friction acting on the sled.

The force of friction is given by the equation:

F_friction = μ × F_normal

where F_friction is the force of friction, μ is the coefficient of friction between the sled and the surface it is on, and F_normal is the normal force acting on the sled.

The normal force is the force exerted on an object by a surface that is perpendicular to the surface. For an object at rest, the normal force is equal to the weight of the object. In this case, the weight of the sled is 50 kg × 9.8 m/s² = 490 N.

Plugging the values for the coefficient of friction, the normal force, and the applied force into the equation gives us the following:

F_friction = μ × F_normal = μ × 490 N = 200 N

The net force on the sled is the sum of the horizontal force applied by the athlete and the force of friction:

F_net = F_horizontal + F_friction = 200 N + 200 N = 400 N

Therefore, the net force on the sled is 400 N.

If you increase the distance between the two parallel slits, the interference bright spots will move closer to the center spot.

This phenomenon is known as the "interference pattern shifting towards the center". The reason behind this shift is that increasing the distance between the slits results in a decrease in the fringe spacing or the distance between the bright spots. This means that the bright spots will be closer to each other, and therefore closer to the center spot.

The mathematical relationship between the fringe spacing (d) and the distance between the slits (D) can be expressed as d = λD/d, where λ is the wavelength of the monochromatic light. As you increase D, the value of d decreases, resulting in a shift of the interference pattern towards the center. In summary, if you increase the distance between two thin parallel slits, the interference bright spots will move closer to the center spot due to the decrease in fringe spacing.

The speed of roller coaster would be 14.8 m/s

To calculate the speed of the roller coaster at point 4, we can use the conservation of energy principle, which states that the initial energy of the system (potential energy + kinetic energy) is equal to the final energy of the system.

Assuming that point 1 is the highest point of the roller coaster and that there is no friction or other energy losses, we can use the following equation:

                           mgh = (1/2)mv^2

where,

m is the mass of the roller coaster,

g is the acceleration due to gravity,

h is the height of point 1 above point 4,

v is the speed of the roller coaster at point 4.

Solving for v, we get:

                                       v = sqrt(2gh)

where,

h is the vertical distance between point 1 and point 4.

Now, we need to find the value of h. The thermal energy generated in going from point 1 to point 4 is not directly related to the height difference, but we can assume that all of the potential energy at point 1 is converted to thermal energy at point 4, and that the roller coaster loses no energy due to friction or other factors.

Therefore, we can use the formula for potential energy:

                                     mgh = 134102 J

Solving for h, we get:

h = 134102 J / (mg)

Substituting the given values, we get:

h = 134102 J / (702 kg x 9.81 m/s^2) = 19.1 m

Finally, substituting the value of h into the equation for speed, we get:

v = sqrt(2 x 9.81 m/s^2 x 19.1 m) = 14.8 m/s

Therefore, the roller coaster would be going 14.8 m/s at point 4.
