How much force to apply to a piston with an area of 10 cm2 to lift an object weighing 200n on a piston with an area of 50 cm2?
400 N 400 N / 10cm2 = 2000 N / 50cm2
Cube M has a side length of 10 mm If Cube Ns side length is double that of Cube M then what is the surface area of Cube N?
The surface area of cube M is 6(10 mm)2 = 6(100 mm2) = 600 mm2 The surface area of cube N would be 6(20 mm)2 = 6(400 mm2) = 2,400 mm2
How many mg are equals to 5 kg?
Kgs are thousands of a gram. mGs are thousandths of a gram. this means that the conversion between mG and Kg is: ((n/1000)/1000), or n/10⁶, where n is the number which you want to convert. So, 5/10⁶ = 0.000005.
What is the momentum of a car weighing 15680 N travelling with a velocity of 86 kmh?
momentum = mass × velocity The SI units require: mass in kg velocity in m/s giving momentum in kg m/s To convert N to kg, divide by acceleration due to gravity which on earth is approx 9.8 m/s² To convert km/h to m/s, multipy by m/km (1000 m/km) and divide by s/h (3600 s/h) → momentum = 15680 N ÷ 9.8 N/kg × (86 km/h × 1000 m/km ÷ 3600 s/h) ≈ 444 kg m/s
What is the weight of a ball with a mass of 77 kilogram?
Short answer 1.3 x 102 N (on moon) 7.5 x 102 N (on Earth if g = 9.80 N/kg Long Answer Since the category is "The Moon" gravity will be assumed to be 1.63 m/s2 (N/kg = m/s2) http://en.wikipedia.org/wiki/Gravitation_of_the_Moon W = mg W = (77 kg)(1.63 N/kg) = 125.51 -> 1.3 x 102 N (significant figures) for earth, just substitute in 9.80 N/kg for 1.63 N/kg W = (77 kg)(9.80 N/kg) = 7.5 x 102 N
