Question

physics numericals physical quantities and measurements ​

Answer 1

Answer:

given,

mass= 4.40kg

volume= 5/1000=0.005

so we can change into all CGS system,

kg into gr

1kg=1000 gr

or, 4.4 kg=1000*4.4=4400gm

again,

m cube into cm cube

m cube= (100*100*100)=5000 cm cube

now we know,

density=mass/volume

density= 4400/5000=0.88gm/cm^3

Answer 2

Answer:

Physics is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.
