-Calculate the density of an object that has a mass of 54 grams and is 3cm by 2cm by 1cm. (Hint: you must use the formula V = l x w x h to find the volume before you can calculate the density)

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

∠gdh and ∠edh on edg.

answer is c

d

explanation:

rutherford's experiment showed that the atom does not contain a uniform distribution of charge.
