Answer:
karyotype is an individual's collection of chromosomes
Explanation:
The term also refers to a laboratory technique that produces an image of an individual's chromosomes.
Answer:
150A
Explanation:
Given parameters:
Potential difference = 120V
Resistance = 0.8Ω
Unknown:
Current = ?
Solution:
From ohm's law;
I =
I is the current
V is the voltage
R is the resistance
Now insert the parameters and solve;
I = = 150A
There must be a conducting wire and electromotive force or free electrons
Let's call the constant acceleration a.
At a time t, its speed will thus be v(t)=a*t+v0 where v0 is its initial speed, here 10 m/s. Hence v(t)=a*t+10.
From there we can deduce the position P(t)=a*t^2/2+10t+p0 where p0 is the initial position, here 0.
Hence P(t)=a*t^2/2+10t
Let's call T the time at which it's at 50 m/s, we know that P(T)=225m and that v(T)=50 m/s hence a*T+10=50 thus a=40/T and P(T)=(40/2+10)T=30T
Hence T=225/30=7.5
It took 7.5 seconds
Answer:
The frequency heard by the observer is 2760.73 hertz. Explanation:
Frequency of source, f = 2640 Hz
Velocity of source,
The speed of sound, v = 343 m/s
Let f' is the frequency heard by the observer. According to Doppler's effect, the frequency of the observer is given by :
(as the source is moving towards observer)
f' = 2760.73 Hz
So, the frequency heard by the observer is 2760.73 hertz. Hence, this is the required solution.
