Answer:
James Prescott Joule
James Prescott Joule, (born December 24, 1818, Salford, Lancashire [now in Greater Manchester], England—died October 11, 1889, Sale, Cheshire), English physicist who established that the various forms of energy—mechanical, electrical, and heat—are basically the same and can be changed one into another.James Prescott Joule experimented with engines, electricity and heat throughout his life. Joule's findings resulted in his development of the mechanical theory of heat and Joule's law, which quantitatively describes the rate at which heat energy is produced from electric energy by the resistance in a circuit.
Answer:
D
Explanation: this is why they have so much more energy released
Lithium Chloride releases 37 kJ of energy per mole when dissolved in water.
Energy released = 0.25 x 37
= 9.25 kJ
= 9,250 J
Temperature change of water may be calculated using
ΔH = mCpΔT
Cp = 4.18 J/g
ΔT = 9,250 / (200 x 4.18)
ΔT = 11.1 °C
Answer:
(a)158.9 N up the ski slope
(b) 0.19
Explanation:
PLEASE MARK ME AS BRAINLIEST
F^k=MkN
158.9=817.7 M*s
Mk=0.19
Answer:
Point A and c
Explanation:
you can know the t is the strongest at either pole of the magnet or closer to pole of the magnet as, which you can see A and C was closest
