Find the ratio of speeds of an electron and a negative hydrogen ion (one having an extra electron) accelerated through the same
Tju [1.3M]

Answer:

42.8

Explanation:

A particle travelling through potential difference V has energy E =qV = 1/2mv²

v = √(2qV / m)

ve = √(2qV / me)

vh = √(2qV / mh)

ve / vh = √( (2qV / me) ÷(2qV / mh) = √ ( mh / me ) where mh = mass of hydrogen ion and me is mass of electron, V voltage is the same, ve is speed of electron and vh is the speed of hydrogen ion

ve / vh  = √ ( mh / me )  = √ ( 1.67 × 10⁻²⁷ kg) / ( 9.11 × 10 ⁻³¹ kg) = 42.8

A 100 g sample of an unknown liquid absorbs 2000 j of heat energy, raising the liquid's temperature from 50 ◦ c to 70 ◦
Mekhanik [1.2K]
Since there is no phase change, we can use the heat equation,
Q = mcΔT 
where Q is the amount of energy transferred (J), m is the mass of the substance (kg), c is the specific heat (J kg⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).

Q = 2000 J
m = 100 g = 0.1 kg
c = ?
ΔT = (70 °C - 50 °C) = 20 °C

By applying the formula,
2000 J = 0.1 kg x c x 20 °C
         c = 2000 J / (0.1 kg x 20 °C)
         c = 1000 J kg⁻¹ °C⁻¹

Hence, the specific heat capacity of the liquid is 1000 J kg⁻¹ °C⁻¹.
