There is a scale with a basket on it. A brick, brick #1 is placed on the scale. The brick has a mass of 10 kg. What are the two forces acting on the brick?
Answers
Answer:
Weight and reaction.
Explanation:
With respect to Newton's third law of motion, action and reaction have equal magnitude but acts in opposite direction.
Thus, the brick of mass 10 kg has its weight (due to gravitational pull of the earth), which acts downwards through its center of mass. This makes the scale to produce an opposing force of equal magnitude, which acts upwards. These two forces acting in opposite directions balancing each other.
The two forces acting on the brick are: its weight and the reaction from the scale.

Is there a difference in how a black shirt or a white shirt affects our exposure to us radiation?
Answers
But there is definitely a difference in heat. If you insist on wearing a black shirt and you want to avoid having a heat stroke then you should probably consider bringing water, maybe an extra shirt and sun screen if you have to be outside for more than 10-15 minutes.
Under the sun, the black shirt absorbs all wavelengths (more light). A white shirt reflects the visible light that hits it.
heat follows the same laws of conservation of light energy. This means light energy and heat cannot be created or destroyed. The light and heat has to go somewhere.
The light doesn’t cause the heat but they follow the same rules so instead of visually seeing the lack of light, you feel the heat energy that is being absorbed by your shirt.
you are exposed to the same amount of radiation wearing a black shirt as you are the white shirt. The difference is the “color” (because some people don’t consider black and white a color) and how light reacts to it.

Explanation:
In root pass welding, that electrode we are going to use cellulosic electrode (E-XX10).
What is root pass welding?Short arc welding is commonly used for root pass welding to prevent blow through and overheating at the weld joint. Because there is less drooping and suck back, short arc welding is also commonly used on root pass joints.
The first pass in any welding process that combines two pieces or members into one structure is referred to as the root pass.
Subsequent passes raise the weld depth to the desired thickness, resulting in the required strength. The first pass usually serves as the foundation for subsequent filler passes.
A 5/32" (4.0mm) diameter electrode is used for the root pass. A cellulosic electrode (E-XX10) is being used. The root pass is welded with reverse (DC+) polarity.
Thus, cellulosic electrode (E-XX10) for this.

Which of the scientist responsible for cell theory would be the most likely to write a book titled Cells Come from Cells
Answers
Answer:
Rudolf Virchow
Explanation:
popularized the cell theory in an 1855 essay entitled “Cellular Pathology.” (b) The idea that all cells originate from other cells was first published in 1852 by his contemporary and former colleague Robert Remak (1815–1865).
Explanation:
Rudolf Virchow
-Rudolf Virchow would be the most likely to write a book titled 'Cells Come From Cells' because in cell theory he added a point that 'All cells arises from pre-existing cells. ' which means that all cells come from another cells which is as similar as the title of the book
What is the volume of the water in the graduated cylinder gizmo Student Volume Lab Sheet (cm3 and mL)
Answers
Answer:
The volume of water in the graduated cylinder will be equal to the calculated volume of the sphere.
Explanation:
The volume of solid objects can be measured by completely immersing these solids in an overflow faucet filled to brim with a liquid in which the solid does not dissolve. This is known as the displacement method. When water is used, it is known as water displacement method.
In the Volume Lab Sheet, a sphere whose volume has been pre-calculated is immersed in the overflow faucet containing water. The displaced water is collected in a beaker and the volume is obtained using a 50 mL measuring cylinder.
The volume of a sphere is calculated using the following formula:
Vsphere = 4πr³/ 3
The symbol π represents the number pi, which is about 3.14. The letter r stands for the radius of the sphere, which is the distance from the center of a sphere to its surface. The radius is exactly half of the diameter, which is the distance across the sphere through its center.
The volume of the water in the measuring cylinder is found to be equal to the calculated volume of the sphere. This is because an object immersed completely in a liquid displaces a volume of liquid equal to its own volume.

is the number of paper clips in step 2 the same as the number of paper clips in step 3? why do/don't you think so?
Answers
The number of paper clips in step 2 is the same as the number of paper clips in step 3 is a true statement, as the mass is the same for both.
What is mass?It is possible to define every mechanical quantity in terms of mass, length, and time. The SI unit for mass, denoted by the letter m, is the kilogram. While mass is typically thought of as an immutable feature of an item, relativistic mass must be taken into account when traveling at speeds close to the speed of light.
Given:
The mas of the paper clips are the same,
Assume the number of clips in step two is x and the mass is m, the mass in the third step is the same as in step 2,
Thus, the number of clips = Total mass of paper clip / mass of one clip,
The number of clips = m / x
As we can see, if the mass is equal, then the number of clips will also be equal.
