Answer:
b) The gravitational pull will be weak.
Explanation:
Less mass requires less force. Gravity or gravitational pull is a force. In order for you to stay in place and not go through the ground, however, you require something to pulling you away from the Earth. That's why we have air resistance.
Answer:
A person's shoe has area of 44cm2 on the ground, their weight is 650N. What is their pressure (in N/cm2) A piece of glass can withstand a pressure of 21000 N/m2, what is the minimum force needed to break the glass with a special hammer of surface 3 cm by 4cm.Ice cracks if the pressure on it is more than 3000 N/m2. If a man of mass 800N wants to safely walk over the ice what area do each of his snow boots need to be in m2.

Hi!
The answers would be <u>chunking</u> & <u>short-term</u>
1. <u>Chunking </u>involves organizing and breaking down information into easier groups to expand capacity.
<h3>Explanation:</h3>
Chunking is a mental process that is observed to increase short-term memory by taking the information and categorizing it into small groups. For instance, a longer number taken as a single unit is harder to recall then when it is divided into smaller units. 235469350 is harder to instantly recall as compared to when it is chunked into 3 groups: 235 469 350.
This allows more information to be stored in, thereby increasing the capacity of the mind to store information.
2. Rehearsal is the verbal repetition of information. These techniques are especially important for the improvement of <u>short-term</u> memory.
<h3>Explanation: </h3>
Short-term memory is lost after a couple of seconds or minutes, for instance even if you chunk the information, you might not recall it after 30 seconds. Rehearsing or repetition of information, either loudly or mentally, extends the time a particular information is retained.
So you depending on the number of times you repeat the number 235 469 350, the more your short term memory improves .
Hope this helps!
We know, length of segment wave is half the wavelength .
Let, wavelength of wave is .
So, length of segment will be .
Now, it is given that the string vibrates in four segments.
So,
Speed can be given by :
Therefore, the wave speed in the string is 120 m/s.
