Does the number of particles change as the substance changes its state?​
Leviafan [203]

Particles stay the same unless there is a chemical change whether the matter is solid, liquid or gas. ... When substances change state there is no change in mass so if 100 g of ice is melted 100g of water are formed this will boil to form 100g of steam (this is called "conservation of mass").

pshichka [43]

Answer:

F = BIl

F » magnetic force

B » magnetic flux density

l » length / circumference

F = BI(2\pi r)

r » radius

F = 2 \times 5 \times (2 \times 3.14 \times 0.05) \\ { \underline{force = 3.14 \:  \: newtons}}

A 230 g air-track glider is attached to a spring. The glider is pushed in 8.2 cm and released. A student with a stopwatch finds
Natasha_Volkova [10]

Answer:

4.3 N/m

Explanation:

m = 230 g = 0.230 kg, x = 8.2 cm

in 13 oscillations, time taken = 19 s

In 1 oscillation, time taken = 19 / 13 = 1.46 s

By the use of formula of time period , Let k be the spring constant.

T = 2\pi \sqrt{\frac{m}{k}}

1.46 = 2\pi \sqrt{\frac{0.230}{k}}

0.054 = 0.230 / k

k = 4.26 N/m

k = 4.3 N/m
