Take water into a syringe, close the hole at the nosil and push the piston. By this experiment you can conclude that 

Given: d1 = 4.24 cm, ∆T = 227 – 27 = 200 °C, α = 1.70 × 10-5 °C-1 To find: Change in diameter (∆d) Formula: α = \(\frac{d_2-d_1}{d_1\triangle T}=\frac{\triangle d}{d_1 \triangle T}\) Calculation: From formula. ∆d =...

B) mass of the car > mass of the bicycle

C) Larger the net force larger the acceleration

(C) Swallowing

The fundamental characteristic of the muscle is contraction. Therefore, muscle can only pull and not push the bone.

A) first increases, then decreases

Correct option is (D) \(7\,\frac{1}{2}\) hrs \(\because\) Time taken to fill a \(50\,l\) of tank = 5 hours \(\therefore\) Time taken to fill a \(75\,l\) of tank \(=\frac5{50}\times75\;hours\) \(=\frac{75}{10}\;hours\) = 7.5 hours = 7 hours + \(\frac12\) hours = \(7\frac12\) hours

“Zaman, can you tell me what I am teaching?” the teacher asked. “I’m sorry, sir, I can’t follow,” replied Zaman. “You can’t because you are not attentive,” the teacher said.
