These are adenine and guanine.
Purines adenine and guanine are double ringed structures that make up DNA. Purines have a characteristic double-ring structure composed of carbon, nitrogen and hydrogen atoms.
Each of purine's rings contain two nitrogen atoms making up a total of four within the double ringed structure. The remaining five positions within the rings are occupied by carbon atoms. The purine ring is encircled by hydrogen atoms which can be replaced by other atoms or groups of atoms to form different purines.
The normal force is always (underline, bold) is always perpendicular to the surface an object is sitting on. If the object is on an inclined plane, then the normal will not be vertical but it will be perpendicular to the angle of the incline.
The diagram below (left) shows a normal force (GH) that is not vertical, but it is perpendicular to the surface. The object on the right is the more usual normal a mass on a table top.
The vertical line on the right is the normal and it points up.
<h2>Frequency of trumpet wire = 445 Hz</h2>
Explanation:
The given frequency of tuning fork is 440 Hz . It produces 5 beats with trumpet wire . That means , the frequency of wire can be 440 ± 5
It can be either 445 or 435
Now the length of wire is increased , by which its frequency decreases . Because frequency is inversely proportional to length of wire .
If we decrease the frequency in 435 , the difference between tuning fork frequency and wire frequency will become greater than 5 even . So it cannot produce 3 beats with it .
If we decrease frequency from 445 , it can become 443 Hz . It gives 3 beat with the tuning fork as given .
Thus the initial frequency of wire is 445 Hz
Answer:
Mechanical energy is the total energy of the body is made up of scientific energy and potential synergy, these two can be converted into one another without needing help.
The most determining factor of kinetic anergy is speed since it is squared
Explanation:
Mechanical energy is the total energy of the body is made up of scientific energy and potential synergy, these two can be converted into one another without needing help. Kinetic energy is the energy of movement, increasing the speed of the body increases the kinetic energy.
The energy powers an energy from the system configuration when changing to a lower energy configuration this is converted into mechanical energy.
The most determining factor of kinetic anergy is speed since it is squared
Vf ( final velocity) = ?
Vo ( initial velocity) = 1.5 m/s
a (acceleration) = .65 m/s^2
t (time) = 2.6 seconds
The equation you want is Vf = Vo + (a)(t).
Plugging in the variables gives Vf = 1.5 + (.65)(2.6).
The final velocity is 1.5 + 1.69, which comes out to +3.19 m/s.
