As the yeast feeds on sugar it creates carbon dioxide, and as the gas has no place to go it slowly fills the balloon up.
Answer:
Reflected line
Explanation:
The angle between the reflected ray and the normal ray is called angle of reflection.
Option C i.e scattering is the correct answer.
Scattering type of Polarization occurs when light strikes the atoms of a material.
Polarization is the process of transforming unpolarized light into polarized light. There are four methods of polarisation--Transmission, Refraction, Reflaction and Scattering.

<u>Electric Circuits</u>
Suppose we have a resistive-only electric circuit. The relation between the current I and the voltage V in a resistance R is given by the Ohm's law:

(a) The electromagnetic force of the battery is
and its internal resistance is
. Knowing the equivalent resistance of the headlights is
, we can compute the current of the circuit by using the Kirchhoffs Voltage Law or KVL:

Solving for i

i=2.28\ A
The potential difference across the headlight bulbs is


(b) If the starter motor is operated, taking an additional 35 Amp from the battery, then the total load current is 2.28 A + 35 A = 37.28 A. Thus the output voltage of the battery, that is the voltage that the bulbs have is

Answer:
For a relative frequency distribution, relative frequency is computed as the class frequency divided by the number of observations.
