Average speed = total distance travelled / total time taken
total distance = 3 + 2.5 + 7 + 10 + 2 = 24.5
total time = 120 seconds
therefore 24.5/120 is
0.2m per second.
Explanation:
When neutral objects are placed in the vicinity of charged objects,they get attracted.
The isolated neutral object has positive charge and negative charge spread throughout it completely.
When a charged particle is brought,the opposite charges in the neutral object occupy the positions near to the charged particle and the like charges occupy the positions far from the charged particle.
This creates a dipole with some dipole moment.
This dipole attracts to the field of the charged particle.
air akan mendidih pada suhu 100 derajat celcius.air akan selalu pada suhu tersebut,jika lebih dari itu air akan menguap
Answer:
option A is correct
Explanation:
acceleration the time rate of change of velocity or speed so
a=Δv/t
Δv=vf-vi
Δv= final speed-initial speed
now a=final speed-initial speed/time
The answer is: " 5 g / cm³ " .

Explanation:
____________________________________________
Density = mass divided by volume ; or: "D = m / V " ;
____________________________________________
and is expressed as: "mass per unit volume" ;
The mass, "m", is expressed in units of "g" (grams) ; and
the volume, "V" is expressed in units of "cm³ " or "mL" ; ("cm³ ", in this case);
{Note the exact conversion: " 1 cm³ = 1 mL " .} .
_____________________________________________________
So, if: the mass, "m = 100 g" {given} ;
and the volume, " V = 20 cm³ " {given} ;
_______________________________
Plug these values into the formula/equation to solve for the density, "D" ;
________________________________________________
D = m / V = (100 g) / (20 cm³)
= (100 ÷ 20) g / cm³ = 5 g /cm³ .
____________________________________________
The answer is: " 5 g / cm³ " .
