The least potential energy would go at the very bottom of the track. the greatest kinetic energy would be on the upper half of the track and the least kinetic energy would be on the lower half of the track. please review this on google if you are not sure.
The absolute simplest way to explain E=MC^2 is: a lot of energy from a little mass.
Answer:
Transmission
Explanation:
It’s the passage of electromagnetic waves through a medium.
Answer:
1.5 x 10⁵ W
Explanation:
A = Area of the fresh lava = 1.02 m²
T = Temperature of fresh lava = 1000 °C = 1000 + 273 = 1273 K
T₀ = Temperature of surrounding = 25.3 °C = 25.3 + 273 = 298.3 K
ε = emissivity of the lava = 0.97
σ = stefan's constant = 5.67 x 10⁻⁸ Wm⁻²K⁻⁴
Rate of transfer is given as
E = σ ε A (T⁴ - T₀⁴)
E = (5.67 x 10⁻⁸) (0.97) (1.02) ((1273)⁴ - (298.3)⁴)
E = 1.5 x 10⁵ W
