Answer:
Forgive me if I'm wrong but I think the answer is C.
Explanation:
I say this because liquid water is H20 (a combination of two elements) and Oxygen is a singular element. Compound is defined as a thing that is composed of two or more separate elements and thus, I think it's C.
Answer: yes it can be prevented
Explanation:
The sensation of weightlessness that astronauts experience seems to make their tasks almost effortless. However, as Newton's third law of motion suggests, working in space can be physically demanding.
As he tightens the bolt, he is rotating in the direction opposite to the bolt
It is possible if the handhold is designed in three dimensional motion where the astronaut motion will be the uplimb motion with the mass centre of hand move along circular helix trajectory
Angular momentum is conserved astronaut motion is conserved when net external torque is Zero.
The distance from point a and point is equal for travels going back and forth. They would just differ in time and speed because of the sea's speed that propels the vessel. The solutions as as follows:
Distance upstream = Distance downstream
99(t + 2) = (99 + 1)(t)
Solving for t,
t = 198 hours
That means that the distance is equal to:
Distance = 99 miles/hour * (198 + 2 hours)
Distance = 19,800 miles
The displacement is determined to be 5.11 m after every direction is plotted on the page.
<h3>What is displacement?</h3>
Displacement is defined as the shortest distance between the two points.
The steps in which Jerry walks;
5m to East
6m to N 60' E,
16m to N30'W,
Turn
3√3 m to the south.
Each and every direction is plotted on the page and obtained that the displacement is found as 5.11 m.

Answer:
The kinetic energy of the electron is 
.
Explanation:
Given that,
The maximum wavelength of a photon is 430 nm.
The frequency of a photon is 
It is a case of photoelectric effect. The relation between the kinetic energy and the the work function as :
So, the kinetic energy of the electron is .
