Based on the data provided, the thermal energies at the given time intervals are as follows:
- At time t = 0.0 secs; thermal energy = 0.0 J
- At time, t = 0.8 secs; thermal energy = 0.0 J
- At time, t = 2.0 secs; thermal energy = 3.9 J
- At time, t = 2.8 secs; thermal energy = 6.7 J
<h3>What is the law of conservation of energy?</h3>
The law of conservation of energy states that the total energy in an isolated system is conserved.
For a ball undergoing energy conversion between kinetic and potential energy, the sum of the energy remains constant.
Any reduction in total energy is due to conversion of some energy to thermal energy.
- Sum of energy: Kinetic + potential + thermal = 15.2 J
- Thermal energy = 15.2 - (PE + KE)
At time t = 0.0 secs
Thermal energy = 15.2 - (15.2 + 0.0)
Thermal energy = 0.0 J
At time, t = 0.8 secs
Thermal energy = 15.2 - (4.7 + 10.5)
Thermal energy = 0.0 J
At time, t = 2.0 secs
Thermal energy = 15.2 - (7.4 + 3.9)
Thermal energy = 3.9 J
At time, t = 2.8 secs
Thermal energy = 15.2 - (8.5 + 0.0)
Thermal energy = 6.7 J
Therefore, the thermal energies at the given time intervals are as follows:
- At time t = 0.0 secs; thermal energy = 0.0 J
- At time, t = 0.8 secs; thermal energy = 0.0 J
- At time, t = 2.0 secs; thermal energy = 3.9 J
- At time, t = 2.8 secs; thermal energy = 6.7 J

Answer:
When the spectral lines are absorption lines, the effect is called inverse Zeeman effect.
Answer:
You didn't add the choices but I'll add some ideas anyway.
Explanation:
Let's start with perhaps the most obvious impact of science on the economy: technology. Scientific discoveries lead to the development of new technologies, which then enter into international markets as highly desirable products.
While humans have always traded technologies, the relationship between technological development and economic growth really dates back to the Industrial Revolution of the 18th and 19th centuries. This was the first time that products were being produced on a massive scale, and it was new technologies in steam engines that allowed this to happen.
As people produced more goods, they developed more complex networks of economic exchange across the world. In fact, our modern ideas about free-market economies and capitalism actually date back to this same time period.
Our modern technologies and our modern economies developed simultaneously. We couldn't have one without the other. Today the United States' economy is very largely dependent on the exportation of communications and digital technologies. Its place in the global economy is not defined by its agriculture or raw products, but by its technologies.

Explanation:
Define: Signals
Before going too much further, we should talk a bit about what a signal actually is, electronic signals specifically (as opposed to traffic signals, albums by the ultimate power-trio, or a general means for communication). When one speaks of analog one often means an electrical context, however mechanical, pneumatic, hydraulic, and other systems may also convey analog signals.
An analog signal uses some property of the medium to convey the signal's information. Any information may be conveyed by an analog signal, often such a signal is a measured change in physical phenomena, such as sound, light, temperature, position, or pressure.
For example, in sound recording, changes in air pressure (that is to say, sound) strike the diaphragm of a microphone which causes related changes in a voltage or the current in an electric circuit. The voltage or the current is said to be an "analog" of the sound.
