It shows that acceleration of particle M is directly proportional to its displacement and its direction is opposite to that of displament. Thus particle M performs simple harmonic motion but M is projection of particle performing U.C.M. hence S.H.M. is projection of U.C.M. along a diameter, of circle.
Answer:
Simple machines can actually make more work due to friction. Simple machines make work easier to do by decreasing the force required by increasing the distance over which the work is done. _____increasing___ the distance that force is applied.
1,000 W = 1 kW
100 W = 0.1 kW
(0.1 kW) x (6 h) = 0.6 kWh <=== energy
(0.6 kWh) x (£0.1359/kWh) = £0.0815 <=== cost of it
Answer:
Mendeleev Arranged it, It was arranged so that elements with the most similar properties were placed in the same group. and the names on the groups are groups 1, 2, and 12–18. These elements are representative metals, metalloids, and nonmetals. Hope this helped
The answer is Helium Flash.
A helium flash marks the looming end of a red giant. As a red giant expands in its outer layers, its core is actually contracting. The core would eventually form a white dwarf.
As the core reaches a certain temperature, helium will start to fuse to form carbon. As this occurs, the fusing of helium, the core heats up. The core is not able to expand to cool down, so the reaction increases the core until the core will ultimately explode.
