Explanation:
They were formed by accretion
Answer:
1. The conversation of momentum is when a person or object has momentum and transfers it to another person or object.
Explanation:
2. Like if someone is on a swing and kicks someone in front of him. He stops and the kid in front of him falls over because the momentum was transferred.
Answer:
(1) A hot drink cooling to room temperature.
(2) The combustion of natural gas.
Explanation:
The spontaneous process is the process in which there is a release of energy and moves towards lower energy and a more thermodynamically stable energy state. All the natural processes are spontaneous.
There are two processes which are spontaneous in the given question are:
(1) A hot drink cooling to room temperature: In this, there is a decrease in energy and also it is a natural process and we know that all the natural processes are spontaneous.
(2) The combustion of natural gas: The fire is an example of an exothermic reaction. The combustion is a combination of a decrease in energy and an increase in entropy. So, this process occurs spontaneously.
Answer:
a).
Wmin= 2471.03 J
W=1603.01 J
Explanation:
Weight, w= 2267 N

Minimum work 'h' is the distance the refrigerator is raised h=1.09m

The motion is no frictional force so, the magnitude of the force with a angle of 45.0° is find using:
