The instrument is a Geiger counter and is used to measure radioactive level around people's bodies.
Answer: Genetic information responsible for physical characteristics such as eye color, height, hair color, and skin color can be found in an organism's <u>DNA.</u>
<u>Explanation:</u>
Our genetic information is stored in DNA. DNA (Deoxyribonucleic acid) molecule is a double helix structure which carries information which used in development and growth of body and determines physical characteristics such as eye color, height, hair color and skin color.
Answer:
The minimum frequency is 702.22 Hz
Explanation:
The two speakers are adjusted as attached in the figure. From the given data we know that
=3m
=4m
By Pythagoras theorem

Now
The intensity at O when both speakers are on is given by

Here
- I is the intensity at O when both speakers are on which is given as 6

- I1 is the intensity of one speaker on which is 6

- δ is the Path difference which is given as

- λ is wavelength which is given as

Here
v is the speed of sound which is 320 m/s.
f is the frequency of the sound which is to be calculated.

where k=0,1,2
for minimum frequency
, k=1

So the minimum frequency is 702.22 Hz
Answer:
I = Δq / t
Explanation:
The quantity of electricity i.e charge is related to current and time according to the equation equation:
Q = It
Δq = It
Where:
Q => is the quantity of electricity i.e charge
I => is the current.
t => is the time.
Thus, we can rearrange the above expression to make 'I' the subject. This is illustrated below:
Δq = It
Divide both side by t
I = Δq / t
