Answer:
Geothermal!!
Explanation:
Geo means earth! Just like Hydro means water, and Pyro means fire :)
Answer:
Water.
Explanation:
This means:
1) For the temperature of water to raise at any point to the next degree by 1°C, will require a specific heat capacity of 4.184 J/Kg°C
2) For the temperature of wood to raise at any point to the next degree by 1°C, will require a specific heat capacity of 1.760 J/Kg°C
Note that: specific heat is directly proportional to energy, therefore the higher the heat capacity, the higher the energy.
4.184 J/Kg°C is higher than 1.760 J/Kg°C, hence WATER needs more energy.
Answer:
The answer is below!!
Explanation:
Gamma-rays
Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancerous cells.

Answer:
.864 M
Explanation:
For first order decomposition,
rate constant k = 1/t x ln a / (a - x )
given , a = 1.33 M , t = 644 s , k = 6.7 x 10⁻⁴ , a - x = ? = b( let )
6.7 x 10 ⁻⁴ = 1/644 x ln 1.33/b
ln 1.33/b = 6.7 x 10⁻⁴ x 644 = .4315
1.33 / b = e⁰ ⁴³¹⁵ = 1.5395
b = 1.33 / 1.5395 = .864 M.
Answer: E = 39.54 N/C
Explanation: Electric field can be determined using surface charge density:
where:
σ is surface charge density
is permitivitty of free space (
)
Calculating resulting electric field:
![E = \frac{[0.3-(-0.4)].10^{-9}}{2.8.85.10^{-12}}](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7B%5B0.3-%28-0.4%29%5D.10%5E%7B-9%7D%7D%7B2.8.85.10%5E%7B-12%7D%7D)
E = 39.54
The resulting Electric Field at any point is 39.54N/C.
