I found this for you
physical equilibria do not involve bond breaking. These are mostly changes of state: solid to liquid to gas. Confusion and ambiguity often occur, especially with regard to solvation. But if new substances are formed chemicalchange is manifest
Answer:
f' =1064.1025 Hz
Explanation:
We know that from doppler's effect
f'= observed frequency
f= actual frequency =1000 Hz
v= velocity of sound waves = 332 m/s
v_o= velocity of observer =0
v_s= velocity of source. ( let velocity of car be 20 m/s)
therefore,
f' =1064.1025 Hz
Answer:
Explanation:
A )
As the two bicycles come closer , the time period of oscillation of bee to oscillate between the two is gradually reduced . It is akin to a pendulum with gradually decreasing amplitude . It will be infinite number of trips the bee will travel before it gets squished .
B )
The bee will survive until the two bicyclists meet each other .
time of their meeting = distance between them / their relative velocity
= 20 / ( 10 + 10 )
= 1 hour .
C )
Total distance travelled by bee during 1 hour
= time x speed of bee
= 1 x 30 km/h
= 30 km .
Throw it sideways and try to make it spin around but it needs to be thrown high up then it should kinda glide down
At one later moment, its speed is 1. 20Mm/s (non relativistic because v is much less than the speed of light).
