The potential difference between two parallel conducting plates in vacuum is 165 V. An alpha particle with mass of 6.50×10-27 kg
shepuryov [24]

Answer:

kinetic energy (K.E) = 5.28 ×10⁻¹⁷            

Explanation:

Given:

Mass of  α particle (m) = 6.50 × 10⁻²⁷ kg

Charge of  α particle (q) = 3.20 × 10⁻¹⁹ C

Potential difference ΔV = 165 V

Find:

kinetic energy (K.E)

Computation:

kinetic energy (K.E) = (ΔV)(q)

kinetic energy (K.E) = (165)(3.20×10⁻¹⁹)

kinetic energy (K.E) = 528 (10⁻¹⁹)

kinetic energy (K.E) = 5.28 ×10⁻¹⁷

Let’s determine what lens is needed to correct the vision of a myopic eye. Assume that the far point of the myopic eye is 50 cmc
koban [17]

Answer:

Explanation:

Person suffering from myopia is unable to see objects beyond 50 cm  because far point of his vision is 50 cm . He requires a concave lens

( diverging lens ) to correct his vision .

After using the lens ,

ray of light coming from far off place will appear to be coming from 50 cm after refraction through lens so it will be focused on retina .

object distance u = ∝

image distance v =  - 50 cm

focal length f = ?

1 / v - 1 / u = 1 /f

- 1 / 50 - 1 / ∝ = 1 / f

- 1 / 50  = 1 / f

f = - 50 cm

focal length is negative so len is concave.

He requires  concave lens of focal length 50 cm .

What is the weight of a 76 kg astronaut on earth on the moon on mars?
Fantom [35]
The weight of a 76 kg astronaut on Earth is 750N.
The weight of a 76 kg astronaut on the Moon is 130N.
The weight of a 76 kg astronaut on Mars is 280N.

The mass is the same everywhere, the weight chages with change of location (gravity field). I rounded all answers to two significant figures. Hope this helps.<span>
