Answer:
nutrients
Explanation:
Nutrients are matter that organisms require for their life processes.
Answer:
Correct answer is Wave A has a greater pitch and frequency
Explanation:
To understand the given figure, we should know the definition of wavelength, frequency and pitch
Wavelength
wavelength is defined as distance between two successive wave crests or troughs.
Frequency
Frequency is defined as the number of waves which passes through a given point per second. SI unit of frequency is Hertz.
Pitch
our ear understand the frequency of a sound wave as pitch. A a lower frequency sound has a lower pitch and a higher frequency sound has a higher pitch.
In given figure Wave A has lower wavelength and higher frequency so it have higher pitch than wave B.
Explanation :
A pictorial representation of a circuit is called as circuit diagram.
The three important components of a circuit are : Power source, wires and load.
Load means a bulb or any other electrical equipment and power source means a battery.
<em>Out of three components, battery must be included in every circuit diagram because it provides voltage and without voltage there is no electric current.</em>
<u><em>The figure shows the symbol of a battery.</em></u>
<h2>mass = 25kg</h2><h2>---------------------------------</h2>
force = 75N --- (<em>g</em><em>i</em><em>v</em><em>e</em><em>n</em><em>)</em>
acceleration = 3m/s² ---- (<em>g</em><em>i</em><em>v</em><em>e</em><em>n</em><em>)</em>
<h3>FORCE = mass × acceleration</h3>
75N = mass × 3m/s²
mass = 75÷3
