This was wrong. Can you solve this again with these numbers? What is the root mean square velocity, vrms, for Hydrogen molecules (H2) at 20oC? Hint: How many amu does an H2 molecule contain. 1 amu = 1.67 x 10-27 kg Boltzman's Constant, k = 1.38 x 10-23 J/K Give your answer in m/s to 4 significant figures (NO DECIMALS)
(a) A person’s blood pressure is measured to be 1202mmHg . What is its percent uncertainty? (b) Assuming the same percent uncertainty, what is the uncertainty in a blood pressure measurement of 80 mm He?
Determine the absolute uncertainty for the calculated value in the following scenarios. Express as (computed result) ± (absolute uncertainty) (units). You measure the volume of a stainless steel sphere by placing it into a100 mL graduated cylinder with an uncertainty of 1 mL, with 20 mL ofwater initially. After the sphere settles, the graduated cylinder now reads22 mL. What is the volume with uncertainty? Please use the formula I posted ! Thank you!
Please help me answer this correctly ASAP. Please write the solution on paper. Thank you. Note: The tolerance is ± 1 in the third significant digit.
Please help me with the following and explain making sure the answer is really really correct 100%. I tried all kinds of calculations and it was wrong so I have no idea what's wrong. When I look at similar questions with different numbers it was 0. ... so i guess it has be something similar maybe but pleas make sure your work is correct pls pls ( wrong asnwer--> 1.31g and 1.35e-12)
Friction Be able to calculate, for both kinetic and static friction: a. The frictional force, given the mass and coefficient of friction, including experimental uncertainty. b. The coefficient of friction, given the mass and frictional force, including experimental uncertainty. c. The mass or the normal force, given the friction coefficient and the applied frictional force, including experimental uncertainty. Be able to sketch a force diagram for a block either at rest or sliding, with friction. Example 1: A block of wood with a mass of 220 g (assumed exact) is sitting on a surface, where the coefficients of static and kinetic friction between the materials are μ = 0.31±0.01, Mk = 0.22 +0.01. What force is required to get the block moving? Quote your answer including an experimental uncertainty. (0.67N ± 0.02N) Once the block is moving, what horizontal force is required to keep the block sliding at constant speed? Quote your answer including an experimental uncertainty. (0.47N ± 0.02N)…

Calculating the Number of Molecules in a Cubic Meter of GasHow many molecules are in a typical object, such as gas in a tire or water in a glass? This calculation can give us an idea of how large N typically is. Let’s calculate the number of molecules in the air that a typical healthyyoung adult inhales in one breath, with a volume of 500 mL, at standard temperature and pressure (STP), which is defined as 0 ºC and atmospheric pressure. (Our young adult is apparently outside in winter.)StrategyBecause pressure, volume, and temperature are all specified, we can use the ideal gas law, pV = NkB T, to find N
