A drop of oil is floating between two parallel plates with a separation of 8.3 mm. If the mass of the oil drop is 2.7 x 10-15 kg

, and its charge is -9.612 x 10-19 C, determine the voltage across the charged plates and determine which plate is positive.

The voltage across the charged plates is  228.5 V.

<h3>Voltage across the plates</h3>

V = Fd/q

V = (mgd)/q

where;

  • m is mass of the oil
  • g is acceleration due to gravity
  • d is the distance of separation
  • q is charge

V = (2.7 x 10⁻¹⁵ x 9.8 x 8.3 x 10⁻³) / (9.612 x 10⁻¹⁹)

V = 228.5 V

Thus, the voltage across the charged plates is  228.5 V.

If planet A is four times as far from the sun as planet C, then the period of its orbit will be__ times as long
Burka [1]
Within the system of the same star, the period of a planet's orbit is
proportional to the 3/2 power of its distance from the central body.
(Kepler's empirical third law of planetary motion, promoted to being
etched in stone by Newton's gravitation.)

(4) ^ 3/2 = <em>8 times</em> as long.

Astronauts measure their mass by measuring the period of oscillation when sitting in a chair connected to a spring. The Body Mas
anzhelika [568]

Answer:

55 kg

Explanation:

spring constant (k) = 600 N/m

mass of chair (Mc) = 12 kg

period of oscillation of chair and man (T) = 2.1 s

what is the mass of the astronaut (Ma) ?

mass of the astronaut (Ma) = total mass (Mt) - mass of chair (Mc)

where

  • total mass (Mt) = \frac{T^{2}}{4π^{2}}k

       taking π as 3.142

       total mass (Mt) = \frac{2.1^{2}}{4 x 3.142^{2}}600

       total mass (Mt) = 67 kg

therefore

mass of astronaut = 67 - 12 = 55 kg
