A comet of mass 1.20 × 10¹⁰kg moves in an elliptical orbit around the Sun. Its distance from the Sun ranges between 0.500 AU and

The eccentricity of its orbit is $$U=-2.13 \times 10^{17} \mathrm{~J} .\end{aligned}$$

<h3>What is mass?</h3>
  • Mass is a physical body's total amount of matter. It also serves as a gauge for the body's inertia or resistance to acceleration (change in velocity) in the presence of a net force. The strength of an object's gravitational pull to other bodies is also influenced by its mass.
  • The kilogram is the SI unit of mass (kg). In science and technology, a body's weight in a given reference frame is the force that causes it to accelerate at a rate equal to the local acceleration of free fall in that frame.
  • For instance, a kilogram mass weighs around 2.2 pounds at the surface of the planet. However, the same kilogram mass would weigh just about 0.8 pounds on Mars and about 5.5 pounds on Jupiter.
  • An object's mass is a crucial indicator of how much stuff it contains. Weight is a measurement of an object's gravitational pull. It is influenced by the object's location in addition to its mass. As a result, weight is a measurement of force.

The length of the semi-major axis is calculated as follows:

where, $G=6.67 \times 10^{-1} \mathrm{~m}^3 / \mathrm{kgs}$

$M=1.99 \times 10^{30} \mathrm{~kg}=$mass of sur

$m=1.20 \times 10^{10} \mathrm{~kg}$ - a mass of the comet

$$\begin{aligned}\therefore \quad \text { At aphelion, } r &=50 \times U \\&=50 \times 1.496 \times 10^{11} \mathrm{~m} . \\U=-\frac{6.67 \times 10^{-11} \times \mathrm{m} 1.99 \times 10^{30} \times 1.20 \times 10^{10}}{50 \times 1.496 \times 10^{11}} \\U=-2.13 \times 10^{17} \mathrm{~J} .\end{aligned}$$

$$U=-2.13 \times 10^{17} \mathrm{~J} .\end{aligned}$$

Superman throws a 2400 n boulder at a villain. what horizontal force must superman apply to the boulder to give a horizontal acc
Ksenya-84 [330]
The boulder has a weight of W=2400 N. The weight of an object is the product between its mass m and the gravitational acceleration g:
W=mg
Rearranging the relationship, we can calculate the mass of the boulder:
m= \frac{W}{g}= \frac{2400 N}{9.81 m/s^2}=244.6 kg

We are told that Superman applies a horizontal force to this object, and as a result, the acceleration of the boulder is a=12.0 m/s^2. We can find the force applied by using Netwon's second law of motion:
F=ma=(244.6 kg)(12.0 m/s^2)=2935 N

Whats is the definition of Parallel Circuit
Aleksandr-060686 [28]
A parallel circuit is one in which there's a place where the flow of current
can split up and follow different paths.

An example might be: 
Two lamps plugged into the same outlet and both turned on.

Current that comes out of the outlet splits up, and parts of it flow
through each lamp.
