Radiation

All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat. Radiant energy spreads out from its source in all directions. ... GAMMA RAYS have more energy than XRAYS, Radio waves, microwaves and ultraviolet waves all have longer wavelengths than visible light. Both X rays and gamma rays have higher frequencies than ultraviolet rays.

Answer:

A solar eclipse happens at the new moon phase, when the moon passes between the sun and Earth. A lunar eclipse happens at the opposite moon phase – at full moon – when the Earth, sun and moon align in space, with Earth between the sun and moon. EarthSky's lunar calendar shows the moon phase for every day in 2021.

Explanation:

During a new moon, it is more or less between the Earth and the Sun, whereas a lunar eclipse ALWAYS occurs during a full moon.

In conclusion, during a new moon, it is more or less between the Earth and the Sun, whereas a lunar eclipse ALWAYS occurs during a full moon.

A.

Explanation:

Answer: An alpha particle is a helium-4 nucleus, it contains gwo protons and two neutrons. So, alpha decay, giving off an alpha particle, does the following:

1)reduces the atomic number (number of just protons) by two. Plutonium has atomic number of 94, take two protons away and you are left with 92 which corresponds to uranium.

2) reduces the mass number (protons plus neutrons) by 4. If you start with 239 and subtract two protons and two neutrons, you are left with 235.

Explanation:

Coral and fish communities showed dramatic declines from 1977 to 1996 due to massive harbor construction and suboptimal land management practices on the watershed. More recently, corrective measures in the form of watershed stabilization and fishing regulations have been implemented.

Coral reefs are endangered by a variety of factors, including natural phenomena such as hurricanes, El Niño, and diseases; local threats such as overfishing, destructive fishing techniques, coastal development, pollution, and careless tourism; and the global effects of climate change—warming seas and increasing levels.

Answer:

Earth's crust, called the lithosphere, consists of 15 to 20 moving tectonic plates. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.

Answer:

If the force exerted by the intern is doubled and the distance is halved, the work done by the intern remains the same. Work done is the force applied to move a body through a distance.

Explanation:

If the Force exerted by the intern is doubled and the distance is halved, the work done by the intern remains the same.

A force must be applied in order for work to be completed, and there must also be motion or displacement in the force's direction.

The amount of force multiplied by the distance moved in the force's direction is known as the work done by a force acting on an item. Work has no direction and only magnitude. Work is a scalar quantity as a result.

Let, initially  Force exerted by the intern is F and distance is d at any angle θ. Then initial work done = Fd cosθ.

Latter,  Force exerted by the intern is doubled and the distance is halved at the same angle θ. Then final work done = F/2 · 2d ·cosθ = Fd cosθ.

Hence, Work done remains same.

A coal-fired power plant is a type of heat engine that uses heat to do work. So, the correct option is D.

A power plant or power station is defined as a facility designed for producing electrical energy from various other forms of energy.

Here,

A coal-fired power plant is a type of power plant, which is used for the production of electricity by using fuels such as coal, oil, etc.

The coal-fired power plants are the most common type of power station. In these power plants, the main burning materials used are the fossil fuels. The coal is pulverized and then burned into a coal-fired boiler. Then, the boiler water is converted into steam using a heat engine. As a result, this steam is used for the spinning of turbines.

Hence,

A coal-fired power plant is a type of heat engine that uses heat to do work.

The statement that is false when describing serous and mucous membranes is that serous membrane always, while mucous membranes always produce mucose fluid.

Serous membranes usually line closed cavities within the body, for example, the pericardial cavity. These membranes secrete a serous or watery fluid.

On the other hand, mucous membranes are thicker, and the line surfaces of the body are exposed to the external environment, for example, the respiratory tract. These membranes secret mucus but sometimes they can secret liquids, an example is the conjunctiva.

The speed of the ball (i.e the velocity since it has a direction in a specified time) is 5.2 m/s before it landed.

From the given information,

For an object moving in a direction in a specified time, the momentum of the object is usually directly proportional to the mass and velocity.

∴

Momentum = mass × velocity

velocity = momentum/mass

velocity = 0.78 kgm/s ÷ 0.15 kg

velocity = 5.2 m/s
