The correct answers are d and f. The moment or torque is 0.02"Nm" clockwise. The arm is 4.9"cm". The torque (or moment of force, angular force) is given by the formula vecM=vecr xx …

Multiply the distance by 2000 and then convert the cm into km 8 cm on the map is #8xx2000# cm actual distance 16000 cm =160 m= 0.16 km 5 cm

rho_"density"=5.0*g*mL^-1 By definition, "density" is the "mass" per unit "volume", and so we take the quotient.... rho_"density"= (200*g)/ (40*cm^3)=5.0*g*cm^-3-=5.0*g*mL^-1... Since we are …

Dec 17, 2017 · OK, pressure is defined as being force per unit area, just need to be careful about the units (especially converting cm^2 to m^2 etc.) So P = F/A but before we can use that we …

We can say that the weight of the dice decreased because of the buoyancy force of water on it. So,we know that, buoyancy force of water acting on a substance = It's weight in air - weight in …

A model train with a mass of #4 kg# is moving along a track at #8 (cm)/s#. If the curvature of the track changes from a radius of #54 cm# to #27 cm#, by how much must the centripetal force …

1.5 * 10^4"g mol"^(-1) Here's my interpretation of the problem The specific volume of a cylindrical virus particle is equal to 6.02 * 10^(-2)"cm"^3"g"^(-1). The radius of the particle is equal to 7Å …

Dec 22, 2014 · The answer is 3.5cents. The balanced equation for propane's combustion is C_3H_(8(g)) + 5O_(2(g)) -> 3CO_(2(g)) + 4H_2O_((l)) In order to determine the heat given off …

a. ~~183ml b. ~~260g A. Assuming that the concentration of the solution presented is in %w/w; thus the formula shown below is applicable to solve this problem. %solution(w/w)=("mass …

The link immediately below the 30 cm point, and all the links below that one, rely on the link immediately above the 30 cm point for support. Therefore I will consider the lower portion as a …
