Answer: 2.7m/s
Explanation:
cyclist fight only against the component of weight along the road (no friction) , that is:
fx =Wsin6° = mgsin6°=68*9.8*sin6°=69.6N downward
so the force that moves the bike over the hill will be equal to fx but upward
Now we now that the power P = 0.25hp= 186.5W is:
P=f*v so v = P/fx = 186.5/69.6 = 2.7m/s
Kinetic, thermal and electrical. There is more then one form of energy
The transfer of heat between the bottom surface of the beaker and water inside it is due to Convection phenomenon. When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. ... The fluid above a hot surface expands, becomes less dense, and rises
Computer simulation is useful because it helps in the prediction of what will likely happen in the future using data from past events.
<h3>What is computer simulation?</h3>
- This is the use of computer models to represents a hypothetical scenarios that are likely to be obtained in the real world.
Computer simulations are useful in studying phenomena in the universe because they help us to achieve the followings;
- It helps in the prediction of what will likely happen in the future using data from past events.
- It saves cost and time of carrying out actual experiments.
- It can help prevent a disaster that may occur in the future.
