Answer:
3,3*10^-11 J
Explanation:
A=Uq=2,08*10^8 V * 1,6*10^-19 C=3,3*10^-11J
Answer:
At the top of the track right before they are about to go down
Explanation:
Right before he’s about to go down he has potential energy because he is not moving downwards... I think.
Answer:
They travel slower than P waves.
They result in much ground motion.
Explanation:
There are three types of seismic waves: P waves, S waves and Surface waves.
P wave are primary waves which require medium to travel. These are fastest waves. S waves are the secondary waves. These are transverse waves. S waves move slower than P waves. Both of these waves can travel through the inner layers of Earth.
Surface waves travel near the surface or above the surface of the Earth. These travel slower than S waves and P waves but have large amplitudes which could much ground motion and cause huge destruction.
Hence, the statements describe the surface waves:
They travel slower than P waves.
They result in much ground motion.
Answer:
When considering the environmental impact of a sewing machine, it is unlikely that this common household appliance immediately conjures images of ecological threat. However, the sewing machine plays a leading role in the fashion industry, which, according to a report by the Ellen MacArthur Foundation, is one of the largest sources of pollution in the world. The report suggests that the textile and fashion industries produce more pollution than aviation and international shipping combined.
Also, with the production of sewing machinery projected to exceed $7 billion this year in China alone, the distribution of those machines will have a massive impact on greenhouse gas emissions. The mass production and distribution of sewing machines, both industrial and domestic, also requires tons of packaging material which negatively impacts the environment. Lonely Whale and the Point Break Foundation estimate that by 2025 there will be one ton of plastic for every three tons of fish in the ocean. Even more alarming, the United Nations suggests that by 2050 there will be more plastic than fish.
Modern domestic sewing machines are made from plastics and polymers, which increases affordability. It also increases the likelihood that consumers will replace rather than repair, especially in the case of handheld sewing machines, which are a growing novelty. With sewing machines constituting an increasing proportion of the millions of tons of household appliances which end up in landfills, this also poses a significant environmental concern.
