Answer:
Explanation:
Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia.

The mass of Jupitar is obtained from the calculations as 5.8 * 10^-14 Kg.
<h3>What is the mass of Jupitar?</h3>
There are nine planets in the solar system and the sun lies at the enter of our solar system. This is the heliocentric model of the solar system.
Given that;
T^2 = GMr^3/4π
T = period
G = gravitational constant
r = radius
M = mass of Jupitar
Now;
1 day = 86400 seconds
1.77 days = 1.77 days * 86400 seconds/1 day
= 152928 seconds
Making M the subject of the formula;
M =4πT^2/Gr^3
M = 4 * 3.142 * (152928)^2/6.67 × 10^-11 * (422 × 10^9)^3
M = 2.9 * 10^11/5.0 * 10^24
M = 5.8 * 10^-14 Kg

Explanation:
Efficiency is the ratio of energy out to energy in.
e = Eout / Ein
0.52 = 800 J / Ein
Ein ≈ 1538 J

Answer:
Explanation:
The energy emitted by a single photon is given by:
where
h is the Planck constant
c is the speed of light
is the wavelength of the photon
For the photons emitted by the zinc atoms,
So the energy of a single photon emitted is
And since the number of atoms is
The total energy emitted will be
