Significant think why scientists presently accept is the key factor in moving information from short term memory is to deliver more the data which is rehashed or utilized, the more probable it is to end up in long-term memory.
<u>Explanation:</u>
Short-term memory (STM) envelops psychological capacities for the capacity, support, and mental control of data that is never again present in the tactile condition. So the Magic number 7 (give or take two) gives proof to the limit of transient memory.
Most grown-ups can store somewhere in the range of 5 and 9 things in their transient memory. It enables the apparent thing important to be changed over into a development that can be put away inside the brain, and afterward reviewed later from the present moment or long-term memory.
Answer:
By the principle of corona discharge.
Explanation:
The charge on each ball will decreases over time due to the electrical discharge in air.
According to the principle of corona discharge, when the curvature is small, the discharge of the charge takes placed form the pointed ends.
Answer:
The atoms are aligned in a particular direction
Explanation:
The atoms become aligned in a particular direction in regions called domains, thus resulting in an overall resultant magnetism due to the spin of the electrons.
Answer:
a. 3/4λ
d. 1/4λ
Explanation:
When the wavelength of the sound waves is λ and the two waves are having same frequency the waves are said to be out of phase if their phase difference is in the multiples of or 180°.
When the two waves are out of phase then their opposite maxima coincide at the same time resulting in the minimum amplitude of the resulting wave throughout.
- As we observe from the schematic that the a wave has sinusoidal pattern of variation and we get a maxima after each of the distance.
- Here we have two speakers out of phase therefore on shifting one of the speakers by the odd multiples of we have the maxima or the extreme amplitudes.
So, we must place the microphone at 3/4λ and 1/4λ to pickup the loudest sound.
