When you float an ice cube in water, you notice that 90% of it is submerged beneath the surface. Now suppose you put the same ice cube in a glass of some liquid whose density is less than that of water.
Answer:
option c
Explanation:
90% of the body is submerged in water.
Now it is immersed in an unknown liquid whose density is less than the density of water.
Buoyant force acting on the body depends on the volume immersed, density of liquid and gravity.
As the density of liquid is less than the density of water, so the buoyant force acting on the body by the unknown liquid is less than water. So it is submerged less than 90% in this liquid.

A researcher claims that the epinephrine signaling pathway controls a catabolic process in muscle cells. Which of the following statements best helps justify the researcher’s claim?.
Catabolism is simply refered to asthe process or sequences of enzyme-catalyzed reactions. Ths statements that best helps justify the researcher’s claim is that Glycogen phosphorylase catalyzes the conversion of glycogen to glucose-1-phosphate.
Catabolism is the process through which a good number of big molecules in living cells are degraded.or broken down into smaller pieces.
Some of the chemical energy released during catabolic processes is conserved in the form of energy-rich compounds such as adenosine triphosphate [ATP].
When anabolic and catabolic processes are in balance state, tissue remains intact and in good shape.

Identify the molecular geometry around the carbon atom highlighted red in the given organic molecule.
The detached carbon has a tetrahedral geometry.
We can arrive at this answer because:
Carbon can make 4 bonds with other atoms.This is because carbon has 4 electrons in its valence layer.When carbon makes 4 single bonds with other atoms it manages to assume a tetrahedral molecular geometry.From questions similar to yours, it is possible to find the image that your question refers to. This image is attached below and on it, we can see that the carbon in red makes 4 single bonds, assuming the tetrahedral geometry.

Two facts that I learned during my research were narrowing down the research topic and setting appropriate goals.
When doing research, several aspects must be taken into account so that the research has good results and produces new knowledge. Here are two tips for proper research:
1. Limit the subject of the investigation: When conducting an investigation it is necessary to limit the subject so that it is easier to achieve an effective result. For example, time limits, a specific place, and more special aspects should be set to make the investigation more specialized.
2. Establish adequate objectives: When conducting an investigation it is necessary to establish objectives that can be achieved in the investigation. Highly ambitious goals can make research and information search difficult.

Which of the following devices is used in this experiment to separate the different wavelengths emitted by the light source?.
A spectrometer employs diffraction to divide light into a spectrum, which is a collection of wavelengths.
What different wavelengths emitted by the light source?A light source beam's wavelengths are spectrally isolated using monochromators. A monochromator separates poly chromatic light into a variety of distinct wavelengths.
The most common application of a spectrometer is to measure the wavelengths of electromagnetic radiation (light) that have interacted with a sample.
A sample may reflect, absorb, or transmit incident light; the way the incident light changes as it interacts with the sample is a characteristic of the sample.
When calculating the concentration of a colored solution, the wavelength of maximum absorbance is used because at this wavelength even a small change in concentration can result in a large change in light absorption.
Therefore, spectrometer devices are used in this experiment to separate the different wavelengths emitted by the light source.

A 400-kg box is lifted vertically upward with constant velocity by means of two cables pulling at 40. 0° on either side of the vertical direction. What is the tension in each cable?.
Answer:
2558 N.
Explanation:Each rope takes half, so the vertical component of the force on each rope is half of this, or 1960 N.. But they are pulling at a 40 degree angle, so if t is the tension then t*cos(40) = 1960. This gives t = 2558 N.

Which situation describes an object that has no unbalanced force acting on it.
The situation which best describes an object that has no unbalanced force acting on it is: A hockey puck moving at constant velocity across ice.
A force can be defined as a push or pull of objects, which typically results in a change of motion due to the interaction of the object with another.
In Science (Physics), there are two (2) main types of force and these are:
Balanced force.Unbalanced force.An unbalanced force is a type of force that occurs when two or more forces acting on an object are unequal in magnitude and as such, it typically results in a change of motion.
Hence, a hockey puck that is moving at a constant velocity across ice has no unbalanced force acting on it because it won't experience a change of motion.

Why does the reactivity of metals increase from right to left.
The outer electron shell of all of the noble gases (Neon, Argon, etc) have a complete octet (except helium which only has and only needs two electrons to complete its valence shell) which makes them very stable and nonreactive. The metals on the left (Na, Li, etc) all contain just one electron in their outer shell which makes them unstable and they tend to form ionic bonds.
Note that the column of elements just to the left of the noble gases (the rightmost column save one), the halogens, is also highly reactive, because the halogens all only need a single elecron to form the "stable octet" in the outer shell.
Sally and ann are trying to move a box across the floor. Sally is pushing the box to the right with a force of 100n and ann is pulling the box with a force of 50n to the right. What is the magnitude and direction of the box?.
Answer:
150N to the right...
Explanation:Force acting on the box applied by Sally, F1= 100 N (right side)
Force acting on the box applied by Ann, F2= 50 N (right side)
It is clear that the two forces are acting on same direction. Let right side is positive direction. So, F= F1 + F2
F= 100+50
F=150 N
The direction of the box is towards the right side. So, the correct option is 150 N to the right... Hope this helps... Plz mark me brainliest.... Stay safe and have a great weekend!!! :D
