It's simple.
We know force is the rate of change in momentum.
So F=(mv-mu)/t or F=m(v-u)/t
=1200*(25-10)/5=3600N
Nowadays, most of the walkie talkies ... and all R/C models ... operate in the "Family Radio Service" (FRS) band. That's 46-49 MHz. The wavelength is 6.12-6.52 meters.
Answer:
TRUE
Explanation:
When the hot and less dense magma rises up towards the surface, the country rocks are heated due to the increasing temperature of the magma. This results in the formation of an aureole that surrounds the intruded magma body. This aureole is commonly known as the metamorphic aureole and contact metamorphism occurs in this area. This type of process occurs at a comparatively smaller area, and where there is a high temperature and low-pressure condition. For example, Hornfels and Marble.
Thus, the above-given statement is True.
The answer is nodes because nodes stay in a fixed position and i just learnt about this!
<h2>Positive Affects:</h2>
- Technology aids in the research of curing diseases or other environmental problems. Without technology, we would not have been able to eradicate diseases like polio.
- Technology allows us to communicate to people quicker, in spite of the distance and conditions.
<h2>Negative</h2>
- Over-dependence of technology makes humans lazy. We won't be paying much attention because everything is available on Google.
- There are health affects due to the radiation. Our vision gets weakened and the laziness can lead to physical problems like obesity and fatigue.
