Acids produce hydrogen ions when placed in water. The concentration of hydrogen ions in a solution is a measure of its acidity. Hydrogen ions cannot be measured directly, so indicators are used to determine whether a solution is an acid, a base, or neutral.
<span>Balanced forces that is acting on an object will NOT cause the object to accelerate, instead it will cause Static Equilibrium-the object is at rest. For example, a book is on the table and there is a downward force because of the gravity but also there is an upward force from the surface that helps to balance the weight of an object which is called a support force. It happens that the net force of an object is equal to zero, means ALL OF THE FORCE CANCEL OUT! Which leads us to the conclusion that, balanced forces will cause an object to be at rest and not to accelerate.</span>
Answer: Resonance
Explanation:
Resonance is a vibration set up in a body (house windows) due to a transfer of energy from another body (loud bass speaker) which is vibrating with a same or nearly equal frequency as that of the first.
Thus, resonance explains that once the natural frequency of the windows happens to be the same as the frequency of the speaker, vibrations occurs.
Horizontal force is applied to the object causing the spring to stretch. the acceleration of gravity is 9.8 m/s
Answer:
I = 1.4 [amp]
Explanation:
To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of the current by the resistance.
Therefore:
V = I*R
where:
V = voltage = 14[V]
I = current [amp]
R = resistance = 10 [ohm]
I = 14/10
I = 1.4 [amp]
