Answer:
require a medium to propagate
Explanation:
this is because electromagnetic waves can travel through vacuum at the speed of 3.0 x 10^8 m/s
because they don't need particles to transfer energy
hope this helps
Magnetic field is proportional to NIA.
N is the number of turns, I is the current and A is the area
You see N=2n, I = 3 i. Therefore, it will 6 times stronger
200*6= 1200 kg. It can lift now is 1200 kg.
Answer:
Half life of S = 3.76secs
Explanation:
The concept of half life in radioactivity is applied. Half life is the time taken for a radioactive material to decay to half of its initial size.
For part 1 - How much signal will be degraded in 1secs = 1/3.9 = 0.2564
for part 2 - How much signal will be degraded in 1secs = 1/104 = 0.009615
Simply say = 1/3.9 + 1/104 = 0.266015
So both part 1 and part 2 took 1/0.266015 = 3.76secs is the half life of S when both pathways are active
Answer:
The rate of evaporation and the rate of condensation are the same.
