'G' = "giga..." = billion = 10⁹
'ms' = "millisecond" = 0.001 second
100 Gw = 10¹¹ watts
35 ms = 0.035 second
100 Gw x 35 ms = 10¹¹ watts x 0.035 second = 3.5 x 10⁹ J
= 3.5 G-joules
Answer:
The right approach will be "47° north of east".
Explanation:
The given values are:
East of prison
= 1.70 km
Displacement vector
= 2.50 km
Now,
The direction will be:
⇒
⇒
⇒
i,e., (north of east)
Mechanical waves require matter to travel medium. If there is no substance or matter to travel through, mechanical waves cannot propagate.
Since space is mostly vacuum, there is no medium for waves to travel through: waves sent by the sun (electromagnetic waves) are not mechanical waves
Explanation:
Below is an attachment containing the solution.
1. Communication
In early ages people were using letters to communicate between them. Now days instantly we can call one person from anywhere, these are based on optical fiber communication and it is an application of physics.
2. Transportation
We can travel from place to anther place by aeroplane , these technologies are introduced after advancement in physics.
3. Construction
Earlier people used to stay in small houses, now days apartments with many number of storeys are built by considering all the forces coming on the structure.
4. Medical Department
The invention of many equipment increased the health of humans.
5. Weather forecasting
The prediction of weather considering all the available factors, prediction of natural disasters all are application of physics.
