For a given wave in a given medium, if the frequency doubles,
the wavelength becomes 50% shorter.
That is, it becomes half as long as it was originally.
An ... (Base ) .... is a compound that turns red litmus paper blue and is often found in soaps and detergents.
If more microscopic technology is invented, then more things in the world can be discovered. Likewise, if a new element is discovered, then people can use it in their technology.
Answer:
e. Only(a) and (b) above are correct
Explanation:
Impulse
= Fx t = m ( v-u )
v-u = change in velocity
F x t = mass x change in velocity
change in velocity = F t / mass
=a t
change in velocity ∝ t ( time ) , if a is constant
dv = a_avg dt
∫dv = a_avg ∫dt
v-u = a_avg t
change in velocity ∝ t ( time )
So both (a) and (b) are correct.
Meters per second, and the time is in minutes, so 14.2 times 60(how many seconds in 1 minute) is 852 seconds then velocity is meters divided by seconds, so 400 divided by 852 is 0.47 m/s rounded to the hundredths place
