Loghan and Kyle should have use the same type of ice cream for all three ice cream containers to get a more accurate result and data
Answer:
Explanation:
frequency of radiation
= 8.54 x 10¹⁴
wave length = 3 x 10⁸ / 8.54 x 10¹⁴
= .3513 x 10⁻⁶ m
= 3513 A
Energy of this wave OR energy of each photon in eV
= 12375 / 3513
= 3.52 eV
the minimum amount of energy required = 3.52 eV.
Wavelength = (speed)/(frequency) = 300,000,000/120,000,000 = 2.5 meters
Answer:
<em>Reason:- We use cotton to make the wick of a spirit lamp because cotton has thread strands which act like fine capillaries and help in drawing up a steady supply of oil in the lamp for burning by capillary action</em>

Answer:
Verdadera.
Explanation:
La caloría se puede definir como una unidad estándar utilizada para medir la cantidad de energía presente en un organismo vivo.
Una caloría (cal) es la cantidad de transferencia de energía necesaria para elevar la temperatura de 1 g de agua de 14,5 °C a 15,5 °C.
Generalmente, es una unidad de medida de energía e igual a 4,1855 julios.
