A. It is bent by raindrops.
B. It is bent the most by the air.
C. It is scattered the least by the air.
D. It reflects off the atmosphere.
Answers
Answer: Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules. So at sunrise and sunset, when the sunlight travels a long path through the atmosphere to reach our eyes, the blue light has been mostly removed, leaving mostly red and yellow light remaining.

What is the worst type of schizophrenia?
Schizophrenia called hebephrenic is the most serious of all and affects more young individuals, between 15 and 25 years of age. The disorder is marked by symptoms such as disturbed affect, irresponsible and unpredictable behavior, disorganized thinking, and incoherent speech.
Undifferentiated schizophrenia — this is the case for patients who may develop some of the characteristics of the other types, but do not fit neatly into any of them.

A cannonball weighs 124.0 N in air, 89.0 N in salt water, and 30.0 N in an unknown liquid, Find the densities of the following: The cannonball, and the unknown liquid
Answers
The densities of the cannonball and the unknown liquid are 3.54kg/m³ and 2.686 kg/m³.
What is the buoyant force?When an object is fully or partially submerged in liquid, the vertical upward thrust is acting on the object, this force is called the buoyant force.
Salt Water exerts a buoyant force to the cannon ball = 124−89 = 35N, which equals the weight of water displaced.
The mass of water displaced is
W/g =35/10 =3.5 kg.
Since the density of salt water is 1kg/L, the volume displaced is 3.5L.
Therefore the density of the cannon ball is
=(124/10) /3.5 =3.54kg/L = 3.54kg/m³
The unknown liquid exerts a buoyant force of 124−30=94 N.
The density of this liquid is (94/10) /( 3.5 )=2.686 kg/liter = 2.686 kg/m³
Thus, the densities of the cannonball and the unknown liquid are 3.54kg/m³ and 2.686 kg/m³.

a ball on a string is swung overhead in a horizontal circle with a radius of 0.66 m. what speed (in m/s) does the ball need to maintain for there to be a centripetal acceleration of 23 m/s2?
Answers
Answer:
The ball is moving in a horizontal circle.
The force acting towards the center of the circle is
F = M a = M * V^2 / R
a = V^2 / R simplifying equation
V = (a / R)^1/2 = (23 / .66)^1/2 = 5.90 m/s

What is acceleration ?Acceleration can be defined as the rate of change of velocity with respect to time, is a vector quantity associated with both magnitude and direction.
Acceleration can be up two types such as Uniform and Non-uniform acceleration, in a circle where speed remains constant but the direction is changing followed by velocity changes, and the body is said to be accelerated.
The average acceleration can be defined as the total change in velocity in the given interval period of time means the total time taken for the change. For a given interval of time, it is represented as ā.
Instantaneous acceleration can be defined as the ratio of change in velocity in a given time interval such that the time interval goes to zero.

The block is pulled to a position xi = 6. 20 cm from equilibrium and released. Find the potential energy stored in the spring when the block is 6. 20 cm from equilibrium
Answers
The value of potential energy stored in the spring when the block is 6. 20 cm from equilibrium is 1.65 J.
What is elastic potential energy?The elastic potential energy is the energy which is stored in a stretched spring. The elastic potential energy of a spring can be found by the following formula.
[tex]U_s=\dfrac{1}{2}kx^2[/tex]
Here, (k) is spring constant and (x) is the displacement of the spring.
The block is pulled to a position xi = 6. 20 cm from equilibrium and released. Thus,
[tex]x=6.20\rm \; cm[/tex]
Divide with 100 to convert its unit in meter,
[tex]x=0.062\rm \; m[/tex]
Let the value of spring constant is 860 N/m. Thus, put the values in the formula,
[tex]U_s=\dfrac{1}{2}kx^2\\U_s=\dfrac{1}{2}(860)(0.062)^2\\U_s=1.65\rm\; J[/tex]
Thus, the value of potential energy stored in the spring when the block is 6. 20 cm from equilibrium is 1.65 J.
