If petroleum used by a power generator is 50 percent efficient and the lines that carry the electricity to a light are 25 percent efficient, what is the energy efficiency of converting the oil into the light

Answers

Answer 1

The energy efficiency of converting the oil into the light can be calculated by multiplying the efficiencies of each step in the process.

Calculation-

Efficiency = (0.50) * (0.25) = 0.125 or 12.5%

So the energy efficiency of converting petroleum oil into the light is 12.5%. This means that only 12.5% of the energy in the oil is converted into usable light. The rest is lost as heat or other forms of energy during the process.

How effective is the process of turning oil into light overall?

How effective is the process of turning oil into light overall? Chemical energy equivalent to 6,000 MJ is found in one barrel of crude oil. An oil-burning power plant can produce 2,000 MJ of energy from a single barrel of crude oil.

Answers

The projectile will probably keep moving in a straight line and at a constant speed as long as no unbalanced forces are acting on it, according to Newton's law of inertia.

What is law of inertia?The law of inertia, also known as Newton's first law, states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity, unless acted upon by a net external force. In simple words, an object will remain in the same state of motion unless acted upon by an external force. This law explains why it is difficult to start an object moving and easy to keep it moving once it is in motion. This law applies to all objects and is a fundamental principle of physics. It also helps to understand the concept of force, motion and energy in physics.

A 3.00kg mass is attached to an ideal spring with k =200N/m ,if the velocity of the body at 0.25 is 2.3m/s find the amplitude and maximum velocity​

Answers

Answer:

To solve this problem, you can use the following formula:

v = sqrt(k / m) * A

In this formula, v is the velocity of the mass, k is the spring constant, m is the mass of the object, and A is the amplitude of the oscillation.

Since you know the velocity of the mass at 0.25 seconds, you can substitute this value into the formula and solve for A:

2.3 m/s = sqrt(200 N/m / 3.00 kg) * A

A = 2.3 m/s / sqrt(200 N/m / 3.00 kg)

= 0.23 m

So, the amplitude of the oscillation is approximately 0.23 meters.

To find the maximum velocity of the mass, you can substitute the values for k, m, and A into the formula for velocity:

v = sqrt(200 N/m / 3.00 kg) * 0.23 m

= 2.75 m/s

So, the maximum velocity of the mass is approximately 2.75 m/s.

The Sun's path, as viewed from the equator, is highest in the sky on _____. A) the spring and fall equinoxes B) the winter solstice. C) the summer solstice D) the day when Earth is closest to the Sun

Answers

The correct option is A, the Sun's path, as viewed from the equator, is highest in the sky on the spring and fall equinoxes.

Fall equinox is an astronomical event that marks the transition from summer to autumn in the Northern Hemisphere and from winter to spring in the Southern Hemisphere. On the day of the fall equinox, the sun rises directly in the east and sets directly in the west. This marks the end of the summer season and the beginning of the autumn season. During the fall equinox, all areas of the Earth experience nearly the same amount of daylight and darkness.  

The fall equinox occurs in the middle of September in the Northern Hemisphere and in the middle of March in the Southern Hemisphere. It is the first day of autumn and the last day of summer in the Northern Hemisphere and the first day of spring and the last day of winter in the Southern Hemisphere.

The fall equinox marks the return of balance after the summer solstice, during which the days are the longest and the nights are the shortest. During the fall equinox, the day and night are of equal length and the sun is directly over the equator. After the fall equinox, the days become gradually shorter and the nights become gradually longer.

An object with mass of 50kg moves with

velocity of 11. 2m/s and an event occur

whereby it transfers 1539 of energy to

another objects as work.

What is the new

velocity of the object after the event??

Answers

The new velocity of the object after the event is 7.99m/s.

We are given that,

Mass = m = 50kg

Initial velocity = v = 11.2m/s

Energy = E = 1539j

The kinetic energy of object can be calculated as,

K= (1/2)mv²

K = (50×125.44)/2

K = 3136J

Consequently, since both the initial kinetic energy and the total amount of energy transferred are known. The article's resulting energy is easily discernible.

Final energy = initial kinetic energy - the ending energy

Final energy  = 3136-1539= 1597 joules

Therefore, using the equation for kinetic energy derivation, the speed of the object can now be determined.

K.E = 1/2MV²

1597 = 50/2V²

3194 = 50V²

V = 7.99m/s

Therefore , the new velocity of the object after the event would be 7.99m/s.

What is the radius of the event horizon of this 10-Solar-mass black hole, in units of kilometers (km)

Answers

The radius of the event horizon of a 10-Solar-mass black hole is 2950 kilometers.

How do you calculate the radius of the event horizon?

The radius of the event horizon of a black hole is known as the Schwarzschild radius and it is a function of the mass of the black hole. The Schwarzschild radius is given by the formula:

r = 2GM/c^2

where

r = radius of the event horizon (in meters)

G = gravitational constant (6.674 x 10^-11 N*(m/kg)^2)

M = mass of the black hole (in kg)

c = speed of light in a vacuum (2.998 x 10^8 m/s)

For a 10-Solar-mass black hole, we can use the mass conversion factor 1 Solar mass = 1.989 x 10^30 kg.

M = 10 x 1.989 x 10^30 kg

Now, we can substitute the values into the formula

r = 2 x 6.674 x 10^-11 x M/ (2.998 x 10^8)^2

r = 2GM/c^2 = 2 x 6.674 x 10^-11 x (10 x 1.989 x 10^30) / (2.998 x 10^8)^2

r = 2.95 x 10^3 m = 2950 kilometers

How do you calculate lever arm in torque?

Answers

We can find the torque of lever arm by the formula Torque(T)=Force * perpendicular distance.

A torque is an action that causes objects to rotate. A torque is required to rotate an object, just as a force is required to move an object in a line. Torque is created by force, but it also depends on where the force is applied and the point about which the object rotates.

Force and lever arm are not always perpendicular. When the force and lever arm are not perpendicular, trigonometry is required to calculate the length of the lever arm. The force applied is perpendicular to the surface of the object rotating. When this force is at an angle θ with the plane of the object, the perpendicular force requires the use of the sine function.

When an object is in rotational equilibrium, the net torque applied to it is zero. For example, if an object such as a see-saw is not rotating, you know the torque on each side is balanced Rotational equilibrium is often used to determine unknown forces.

The following statements are true based on the H-R diagram:

Most stars are located on the main sequence, which runs from the upper left to the lower right of the diagram. This represents stars that are burning hydrogen in their cores and are in a state of equilibrium.

Stars located in the upper right corner of the diagram are brighter and hotter than those on the main sequence and are known as "giants" or "supergiants". They have exhausted the hydrogen in their cores and are in a later stage of their evolution.

Stars located in the lower left corner of the diagram are cooler and less bright than those on the main sequence and are known as "dwarfs". These stars are in the early stages of their evolution and are still burning hydrogen in their cores.

Stars located on the horizontal branch are burning helium in their cores, this represents stars that are in a different stage of their evolution.

There is a clear relationship between a star's luminosity and its temperature, with hotter stars being brighter than cooler stars.

The diagram shows that there is a wide range of luminosities and temperatures among stars, with some being much brighter and hotter than others.

A capacitor is made up of two conducting plates that are separated from one another by a substance known as the dielectric.A capacitor is an electrical component with two terminals that has the ability to store energy in the form of an electric charge. Two electrical cables are used, and they are spaced apart. Vacuum or an insulating substance known as a dielectric can fill the gap between the conductors. To keep the voltage at a specific level, capacitors are also employed. The voltage pulsation can be lessened by using them.
