  • How many meters are there in 235 cm? + Example - Socratic
    2 35 meters Since there are 100 centimeters in a meter, you simply divide by 100 to get meters, since every 100 centimeters is one meter For example, 100 cm is 1 m 110 cm is 1 10 m, since the extra ten are a tenth of a meter Anything else is a hundredth or lower, respectively
  • 54 cm is how many inches? + Example - Socratic
    54 cm ≈ 21 Inches In chemistry, you can do a conversion factor See the image below: (I'm very sorry, this picture has a typo, the 0 492701 In should be 0 393701 In I'm very sorry for this inconvience) Since we are doing a conversion factor, a unit has to be cancelled out In this example, it is centimeters We now, simply multiply across and solve for the answer in inches Since we have
  • A rock weighing 30. 0 g is placed in a graduated cylinder . . . - Socratic
    rho=5 66g" "cm^3 Since the water level rose from 22 3mL to 27 6mL, then that must mean that, the 30g of rock is equal to 27 6-22 3=5 3mL We know that a rock cannot be 5 3mL because that doesn't make any sense! But, we can convert 5 3mL to cm^3 Know that, 1mL=1cm^3 So, the rock is 5 3cm^3 in volume The formula for density is rho=m V, where m is the mass of th e object in kg, g, etc , and V
  • Question #eaefd - Socratic
    #lambda = 4 369 xx 10^-7" cm"# Convert the wavelength from centimeters to meters: #(4 369 xx 10^-7" cm") 1(1" m") (100" cm") = 4 369 xx 10^-9" m"# #lambda = 4 369 xx 10^-9" m"# The speed of light is: #C = 3 0xx10^8" m s"# Substitute the values for #lambda# and #C# into equation [1]: #f = (3 0xx10^8" m s") (4 369 xx 10^-9" m")# #f = 6 87xx10^16
  • Question #8b75f - Socratic
    Volume can be mL, cm^3, m^3, etc The unit for the answer 11 34 is in grams, so mass is in grams When grams are used in a density value, the volume is usually cm^3 or mL So I'm going to use g cm^3 as the density unit So 11 34g should be be 11 34g cm^3
  • Question #fb094 - Socratic
    You can easily convert by remembering that the prefix #k# means 1000, and the prefix #c# means 1 100 so there are 100 cm in a m
  • How many miles is 72 cm? - Socratic
    It's approximately 0 00045 mi Let's first convert this to metres: 72 cm = 0 72 m A metre is roughly 3 28 feet, so: 0 72 xx 3 28 = 2 3616 ft There are 5280 feet in every mile, so we divide: 2 3616 5280 is approx =0 00045 mi
  • Question #8185a - Socratic
    101,332 Pa Pressure is defined as force per unit of surface In this case, if you have a mass of 1034 g, then the force with which it will push down on the unit surface, i e its weight, will be equal to F = m* g, where g - the gravitational acceleration, equal to "9 8 m s"^2
  • Question #20474 - Socratic
    The answer is 280 cm^3 A solution's percent concentration by mass is defined as the mass of the solute divided by the mass of the solution and multiplied by 100% c = m_(solute) m_(solution) * 100%, where m_(solution) = m_(solvent) + m_(solute) We know that m_(solution1) = 70g and the the concentration is equal to c_1 = 10%, which means we can determine the mass of KCl used for the mixture m
  • What is the moment of inertia of a rod with a mass of
    =40 5kgm^2 Let l be the length, m mass, s area of cross section and rho the density of a thin rod rotating about its center Its moment of inertia about a perpendicular axis through its center of mass is determined by the following volume integral If the rod is placed along the x-axis and the center of rotation be the origin, the volume integral reduces to length integral, I_{C, "rod"} = int
