Answer:
Power is 1061.67W
Explanation:
Power=force×distance/time
Power=65×9.8×15/9 assuming gravity=9.8m/s²
Power=3185/3=1061.67W
Answer:
a
The total distance is 
b
The displacement is

Explanation:
From the question we are told that
Distance traveled by the ball for first player
to the right
Distance traveled by the ball for second player
to the left
The total distance traveled by the ball is mathematically represented as

Substituting values


The displacement is mathematically represented as
This is because displacement deal with direction and from the question we are told that right is positive and left is negative
Substituting values


The most probable answer for this question would be that almost every life process requires specialized cells in multicellular organisms. To simply put it, cells of multicellular organisms are specialized in a way that they are all grouped into their respective tissues and these tissues are all grouped into their respective organs and these organs are all grouped together into their respective systems and these systems make up the multicellular organisms. These systems have their own functions in maintaining and sustaining the life that the organisms has. The organs have their own functions as well, thus specialized cells are mostly needed in respiration, digestion, circulation, movement, excretion, reproduction, immunity, coordination, and synthesis.
Answer:
The Prokaryotic Cells and The Eukaryotes
Answer:
Frequency change by a factor of 2.
(b) is correct option.
Explanation:
Given that,
Mass = 16 kg
Replaced mass = 4 kg
We need to calculate the frequency
Using formula of frequency

Put the value into the formula

....(I)

...(II)

Hence, Frequency change by a factor of 2.
