Answer: chemical

Explanation:

A battery stores energy in the form of chemical energy. Chemical energy is stored in the bond of atoms and molecules. These bonds break and convert to other forms of energy. In the given case, the chemical energy is converted to electric energy which powers the flashlight. Thus, flashlight receives energy input in the form of chemical energy.

How long will it take a ball to hit the ground if it's dropped from a height of 2.0 m?
love history [14]

Answer:

0.63 s

Explanation:

We have,

  • Height, h = 2.0 m
  • Initial velocity, u = 0 m/s
  • Acceleration due to gravity, g = 10 m/s²

We have to find the time taken.

⠀⠀⠀⠀⇒ h = ut + ½gt²

⠀⠀⠀⠀⇒ h = ½gt²

⠀⠀⠀⠀⇒ 2 = ½ × 10 × t²

⠀⠀⠀⠀⇒ 2 = 5 × t²

⠀⠀⠀⠀⇒ 2/5 = t²

⠀⠀⠀⠀⇒ √(2/5) = t

⠀⠀⠀⠀⇒ <u>0.63 s = t</u>

Therefore, time taken is 0.63 seconds.

At what temperature (in Kelvin) will the diffusion coefficient for the diffusion of species A in metal B have a value of 6.48 ×
Vikki [24]

Answer:

= 1227.9K

Explanation:

Given that,

D₀ = 4.0 x 10⁻⁵ m²/s,

Qd =  230,000 J/mol,

D = 6.48 x 10⁻¹⁵ m²/s

Gas constant R = 8.31 J/mol-K

T = -\frac{Q_d}{R* (InD - IND_0)}

  = -\frac{230000}{8.31* (In(6.48 * 10^-^1^5) - In(4.0 * 10^-^5)}

  = \frac{-230000}{-187.307}

  = 1227.93K

  ≅1227.9K
