The key phrase in the sentence is: "They must be up to something." This is an idiomatic expression in English, which implies suspicion of secretive or mischievous behaviour.

From the radiation: V = +at, and if it starts from N & T, U = 0 And for angular motion, W = O + at 4R = aχ5 ∴ a = (4a)/5 = 0. 8\(\pi\) rads-2

Centipetal force of the car = ma = \(\frac{(MV^2)}{\text{r}}\) = \(\frac{(1500 \times 40 \times 40}{50}\) = 48000 = 4.8 x 10\(^4\) N

The force of attraction between the two spheres is given by F (GM1 M2)/r2 = (6.67X 10-11 X5X10)/(0.3)2 = 3.71 X 10-8N.

Efficiency = (M.A)/V.R X (100)/1 But M.A = (Load)/Effort = (1600)/800 = 2 Efficiency = (2)/4 x (100)/1 = 50%

In general, pressure varies with depth in the relation p = \(\rho\)gh = 850 x 10 x 500 = 4250000 = 4.25 x 10\(^6\) Nm\(^{-2}\) Therefore, Total pressure = 1.05 x 10\(^5\) + 4.25 x 10\(^6\) = 4.36 x 10\(^6\) Nm\(^{-2}\)

The unit of a couple is Newton-meter (N M)

Wt in the air = 250N wt. in the liquid = 200N loss in wt. in the liquid = 250 - 200 = 50N ∴ mass of liquid displaced = 50N → 5kg ∴If the density of the liquid is 1000kgm-3 then the volume of the liquid = (M)/D = V = (5kg)/1000 = 0.005 → 5.0 X \(10^{-3}\)\(m^3\)

The constriction in the stem of a clinical thermometer prevents the mercury from returning to the bulb after the temperature has been taken, allowing for a more accurate reading. This feature is what distinguishes it from other types of mercury thermometers, which do not typically have this constriction

Using the liquid of high volume expansively II only

Electricity heat energy supplies by the heater = lvt = 3.5 x 200 x (2 x 60) = 84000j. and this heat is supplied to the 2 kg of the water MC ∆ t = 84000 2 x 4200 x ∆ t = 84000 ∴ ∆t = (84000)/8400 = 10°c ∴ increase in temp. of water = 10°c
