<span>AS T1,T2,T3 are the tensions in the ropes,assuming that there are Three blocks of mass 3m, 2m, and m.T3 is the string between 3m and 2m,T2 is the string between 2m and m ,T1 is the string attached to m thus T1 pulls the whole set of blocks along, so it must be the largest. T2 pulls the last
two masses, but T3 only pulls the last mass, so T3 < T2 < T1.</span>

a and b are the correct answers
Explanation:
Answer
According to prevailing gender stereotypes most important characteristics associated with men and woman are as follows
1. Domestic behaviors is one of the basic stereotypes. Some people have thinking that women will cook for family, she will take care of the children, she will do loundary and will clean the house. About man they thought he will take care of finances, will pay the bills and do the home repairs.
2. Some people thought that women are emotional and submissive, while men are thought to be self-confident and aggressive.
3.Some people thought that the most common occupation for women are teaching and nursing while the rest of the occupation are for men like pilots, doctors, and engineers are men.

5. Dressing of men and women also thought to be different. Usually men expected to wear pants and short hairstyles whele women are expected to wear goun, frouks and make-up.
Answers:
a) 154.08 m/s=554.68 km/h
b) 108 m/s=388.8 km/h
Explanation:
<u>The complete question is written below:
</u>
<u></u>
<em>In 1977 off the coast of Australia, the fastest speed by a vessel on the water was achieved. If this vessel were to undergo an average acceleration of 
, it would go from rest to its top speed in 85.6 s. </em>
<em>a) What was the speed of the vessel?
</em>
<em>
</em>
<em>b) If the vessel in the sample problem accelerates for 1.00 min, what will its speed be after that minute? </em>
<em></em>
<em>Calculate the answers in both meters per second and kilometers per hour</em>
<em></em>
a) The average acceleration 
is expressed as:
(1)
Where:
is the variation of velocity in a given time 
, which is the difference between the final velocity 
and the initial velocity 
(because it starts from rest).
Isolating from (1):
(2)
(3)
(4)
If 
and 
then:
(4)
b) Now we need to find the final velocity when 
:
<em></em>
(5)
(6)
Answer:
66.02m/s
Explanation:
the equation describing the distance covered in the horizontal direction is
but the acceleration in the horizontal path is zero, hence we have
Since the horizontal distance covered is 155m at 7.6secs, we have 
Also from the vertical path, the distance covered is expressed as
since the horizontal distance covered in 7.6secs is 195m, then we have
Hence if we divide both equation 1 and 2 we arrive at
Hence if we substitute the angle into the equation 1 we have
Hence the initial velocity is 66.02m/s
