1. Volume of the solution (B)
2. Celery (D)
3. Hydroxide ions in solution (A)
Answer:
d. the same within the uncertainty of each measurement method
Explanation:
The density of an object and in general any physical property, has the same value regardless of the method used to measure it, either directly or indirectly. Since two completely different valid methods are used, the results must be the same, taking into account the level of precision of each of the methods.
Answer:
The correct answer is option 'c': 30 AUs
Explanation:
For a spherical wave front emitted by sun with total energy 'E' the energy density over the surface when it is at a distance 'r' from the sun is given by
This energy per unit area is sensed by observer as intensity of the sun.
Let the initial intensity of sun at a distance 
be 
Thus if the sun becomes 900 times dimmer we have
Thus the distance increases 30 times.
Physical education is when you are taught about your body and the physical things you can do to keep it healthy. You are taught how to do exercises to keep healthy and what foods you should eat. Physical education means to be educated about your physical abilities and health.
Produced the model is the resistance of the circuits decreased as a battery voltage increased (option-B).
<h3>What connection does there exist between voltage and current, current and resistance, and voltage and resistance?</h3>
Ohm's Law describes how current, voltage, and resistance are related to one another. According to this, as long as the temperature doesn't change, the current flowing through a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
The more work a certain quantity of electrons can accomplish at a given voltage. The quantity of electrons that are presently moving through any one point in a circuit at any particular time is known as the current. At the same voltage, a larger current can perform more work. Current times voltage equals power.
