Answer:
Activation Energy
Explanation:
Effective collisions are those that result in a chemical reaction. In order to produce an effective collision, reactant particles must possess some minimum amount of energy. This energy, used to initiate the reaction, is called the activation energy.
The answer is c) RNA contains uracil and ribose.
Answer:
a) Current.
Explanation:
The "junction rule" (Kirchhoff's first law) says that the value of the electric current entering any point in the circuit must be the same as the one leaving it. This comes as a consequence of the conservation of charge, the electric charge that comes in must come out (when speaking about currents, per unit time).
Answer:
Angle of reflection at plane surface of prism = 30°
Explanation:
Angle of reflection = angle of incidence at any surface plane or curved .
Here angle of incidence at plane surface of prism = 30°
Angle of reflection at plane surface of prism = 30°
If i be the angle of incidence and r be angle of refraction
sin i / sin r = refractive index
= 1.52
sin r = sin i / 1.52
= sin 30 / 1.52
= .5 / 1.52
= .3289
r = 19.2 °
According to the plot, the positions at time <em>t</em> = 0 s and <em>t</em> = 19 s are -1 m and -2 m, respectively. So the average velocity for the 19-s interval is
