Provide the answers to the following questions. 1. If a stone with a mass of 25 g is lowered into a beaker holding a volume of water equal to 2.0 mL and the height of the water rises to 7.0 mL, what is the density?


2. What is the density of copper if a 10.0 cm3 sample has a mass of 89.6 g?


3. What is the density of nitrogen gas if 0.256 g occupies a volume of 100mL?


4. A wooden cube 3.0 cm on each side has a mass of 27 g. What is the block’s density?


5. Assume that silver and gold have densities of 10.5 g/cm3 and 19.3 g/cm3 respectively. Which would have a greater mass, 5 cm3 of silver or 5 cm3 of gold?


6. Five mL of ethanol has a mass of 3.9 g whereas five mL of benzene has a mass of 4.4 g. Which liquid is denser?


7. Consider a block of iron with the dimension of 2 cm x 3 cm x 2 cm. If the mass of this block is 94 g, what is the density of iron?

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
