A body of volume 0.046m³ is immersed in a liquid of density 980kgm‾³3 with 3/4 of its volume submerged. Calculate the upthrust on the body. [g = 10ms‾²]
A. 11.27N B. 33.81N C. 112.70N D. 338.10N Correct Answer: Option D C. 112.70N Explanation m = D x V = 980 x 0.046=45.08×10=450.80N then ,3/4 of it vol immersed in water ; 3/4×0.046×980=33.81×10=338.10N so,the upthrust= weight in Air- weight in water =...In a hydraulic press, a force of 40N is applied to the smaller piston of area 10cm². If the area of the larger piston is 200cm², calculate the force obtained
A. 800N B. 500N C. 80N` D. 50N Correct Answer: Option A A. 800N Explanation F2=(F1×A2)/A1=(40×200)/10=800NWhich of the following properties of a steel bar can be measured in terms of the dimension of length only?
A. weight B. density C. pressure D. volume Correct Answer: Option D D. volumeIn which of the following states of matter do the molecules vibrate about their mean positions?
A. liquids only B. solids only C. liquids and gasses only D. solids, liquids and gases Correct Answer: Option B B. solids onlyProducts
