What is the difference between a rocket and a satellite?
A rocket is a vehicle that launches payloads into space, while a satellite is an object that orbits a planet or celestial body. Rockets are used to propel satellites into orbit where they can perform various functions such as communication, navigation, and Earth observation.
What is a satellite dish used for?
A satellite dish is used to receive signals from satellites in space, typically for broadcasting television, internet, or radio signals. The dish reflects and focuses the signals onto a receiver, allowing users to access a wide range of content and services.
What are the problems of solar energy?
There are several problems with solar energy. Most of these problems though are being solved. Solar energy has come a long way in just the last few years. 1. Cost - the single largest hurdle solar energy faces is that competing energy sources have always been cheaper in terms of dollars per kilowatt-hour (a standard measure). Compared to electricity from coal-fired power plants, solar is more expensive - if you don't consider the environmental costs (which typically are hard to asses a dollar amount to). But in recent years solar power is becoming closer and closer to grid-parity on price especially with the introduction of new types of solar panel chemistry like Cadmium telluride. 2. Site suitablity - many sites don't receive enough solar energy to make solar energy cost effective. Cloudy areas with frequent rain are often not as well suited for solar panels because typically solar panels need direct sun to produce the most power. That's changing though, new panels can now use diffuse light on cloudy days to still produce power. With prices going down steadily, more sites would be feasible that once were not. 3. Embodied energy - It takes a tremendous amount of energy to produce a solar panel. Because of this - depending on the type of panel and the way it was made - the panel itself may have required 11 years worth of its energy production just to make it. So if that's the case, the panel won't begin making 'new' energy until it has been operating for 11 years. It takes energy to make them, and you can think of this like taking out an 'energy loan' and so the loan must be paid back before an 'energy profit' can be made. Again, this is changing, new panels are made more efficiently, and require less material than older technologies so the 11 years is highly dependent on the type of panel and the manufacturing process. 4. Production and Demand - Typically solar panels produce the most energy during the middle of the day and somewhat less before and after than. Also, solar panels produce the most power during the summer. To the extent that demand for power does not coincide with this production curve, other sources of energy must be used to fill in, or some sort of storage (like batteries) is needed. 5. Materials - The material used to make solar panels is in short supply or the supply has fluctuated. This, again, depends on the type of panel, some panels don't have this problem. Shortages in materials mean it can be hard for producers to meet demand - thus pushing up the cost - which is the main stumbling block for the adoption of solar energy.
What is orbiting the earth and taking pictures of it?
A satellite is orbiting the Earth and taking pictures of it. Satellites are equipped with cameras that capture images of Earth's surface for various purposes, such as weather monitoring, environmental analysis, and mapping.
Can Solar energy reduce carbon dioxide pollution?
If it replaces power that would otherwise produce carbon dioxide, then it must do so, because it does not emit CO2. This is not taking account of the process of manufacture of the solar panels-this may cause some pollution. Addition: The CO2 cost of manufacturing solar panels is cancelled out in just a few years of using the solar panels for energy, whether they are photovoltaic panels for electricity, or solar thermal panels for heating hot water.
What energy transformation is taking place when a boy is cycling down a hill?
kinetic energy
Which energy transformation is taking in an electric motor?
Usually electrical energy is transformed into mechanical or kinetic energy
What energy transformation is taking place when you use an electric can opener?
kinnetic
What is the energy transformation taking place when a person jogs at the park?
Chemical energy is transferred into kinetic energy. When a person jogs, motion is produced.
What kind of energy transformation is taking place in the caterpillar's body while the caterpillar eats the leaf in the photograph?
Chemical Energy -> Kinetic Energy
What the energy transformation taking place in a torch?
In a torch, electrical energy from the battery is transformed into light energy and heat energy by the bulb and may also produce a small amount of sound energy.
When a gas stove burns propane gas to cook food what energy transformation is taking place?
The propane gas is being chemically converted to heat energy during the combustion process in the gas stove. This heat energy is then used to cook the food, resulting in a transformation from chemical energy to thermal energy.
What is the most likely evidence of an energy transformation taking place when a wire that is twisted and turned breaks?
The most likely evidence of an energy transformation when a twisted wire breaks is the release of heat. The twisting and turning of the wire causes friction between the wire molecules, which results in the conversion of mechanical energy into heat energy.
What is the energy transformation taking place when a person runs?
The energy in chemical bonds (from food) is turned into:kinetic energy (moving mass), noiseheat (shoes heat up , the runner's body get warm)
What is the energy transformation taking place in solar cooker?
Radiant energy -> electrical energy -> thermal energy
What is the energy transfer for a rocket taking off?
The energy transfer for a rocket taking off involves the conversion of chemical energy stored in the rocket's fuel into kinetic energy as the rocket accelerates. As fuel is burned, it releases energy in the form of heat, which is then used to propel the rocket upwards. This process involves a transformation of potential energy to kinetic energy as the rocket gains altitude and velocity.
What energy transformation are taking place with the radiometer?
In a radiometer, light energy is converted into rotational kinetic energy. The light causes the vanes inside the radiometer to spin due to the pressure exerted by the photons on the reflective surfaces of the vanes.
