(ب). غزل اور نظم کے شعر میں بنیادی فرق کیا ہے؟​

Answer:

asphalt is a mixture of sand, aggregate,and bitumen.in asphalt, bitumen is used as a binder to hold together the asphalt, therefore asphalt is a concrete mixture whereas bitumen is binder or cement for pavement

Answer:

(c) Asphalt is not a natural adhesive among the given options.

Explanation:

• The adhesives made using organic sources namely, vegetable starch, resins obtained from plants, animal-based proteins are known as 'natural adhesives'.
• Soybean adhesives are made up of soy flour and characteristic crosslinking resin. Therefore, it is considered a natural resource.
• Shellac is obtained from a product termed gum lac which is in turn obtained from the secretions of an insect (Kerria lacca ) female.  
• Asphalt often referred to as bitumen, is not a natural adhesive since it is a semi-solid form of petroleum.
• Urea-formaldehyde resin is obtained from any class of synthetic resins, which are built using natural polymers, combined with urea and formaldehyde.

Answer:

33 is the correct answer

The answer to the given question is written below.

• The first option which is '39' is incorrect because it is not mentioned in the UDISE guidelines.
• The second option which is '30' is incorrect because it is not mentioned in the UDISE guidelines.
• The third option which is '36' is incorrect because it is not mentioned in the UDISE guidelines.
• The fourth option which is '33' is correct because it is mentioned in the UDISE guidelines.
• Thus, the correct answer will be '33'.

mark me brainlest

Answer:

98 W

Explanation:

Mass of the man = 50kg.

He moved 25 steps of 16cm high each within 20 seconds.

Here, If one step measures 16cm.

Then, 25 steps would measure = 16*25 = 400cm or 4m

Calculating the force :

Force = m*g

g = 9.8m/s²

mass= 50kg.

force = 50 × 9.8

= 490N.

Work done by the man = force * displacement.

Where, The force is 490N.

Total displacement is 4m.

So, the work done by him is= 490*4

=1960 joules.

Power = Work done/Time

Where, Work done = 1960

Time= 20s

Power= 1960/20

= 98 W

Answer:

A 50 kg man moved 25 steps up in 20 seconds. The power is 100W, if each step is 16 cm high.​

Explanation:

A man whose mass is 50kg climbs up 25 steps of a stair in 20s

each step is 16 cm high

Height at 25 steps , h=25×0.2=5 m

Change in potential energy , =mgh=50 × 10 × 5 =2500 J

So, Work done by the man , W=2500 J

Power used , P= W/t= 2500/25 =100 W

Hence the power is 100 W.
