Someone please help! It is a few science questions. Fairly easy!What is the mass of 100 ml of corn oil?
What is the volume of 35g of copper?
A rectangular solid is of unknown density is 5 metes long, 2 metes high and 4 meters wide. The mass of this solid is 300 grams. Given this information for this homogeneous (alike through) material, calculator its density.
I know that Density=mass/volume but i don't know the volume for that one ^
Please answer fast!
Answers
Mass=Density×Volume
2)
3)
the second one the answer is 8.80 :)
and for the third one the density is 7.5
i hope this is helpful
have a nice day

Answer:
Explanation:
5. Limestone typically doesn't accumulate in the ocean at depths below 4,000 meters because below that depth, calcite is ___not preserved ____.
The calcite compensation depth CCD is the depth at which the rate of dissolution of calcite increases beyond that of accumulation.
6. Based on the principle of original horizontality, geologists conclude that layers of sedimentary rock that have been tilted must have been subjected to __tectonic forces_____.
Tectonic forces causes changes in a particle terrain
7. Based on the principle of inclusions, the cobbles in conglomerate must have been formed __earlier than_____ the conglomerate.
The principle of inclusion states that the inclusion is older than the rock that contains it.
8. Geologists use the principle of __fossil and fauna succession _____ to justify using fossils in a sample of sedimentary rock to determine the rock’s age.
The principle of fossil and fauna succession was credited to Williams Smith and it is used for relative dating of a sedimentary sequence. Here, fossils of plants and animals are used to date a sequence.
9. Partings between adjacent beds of sedimentary rock may represent periods of __unconformity _____, which could range from a few decades to a few centuries.
An unconformity is a period of non-depsotion or erosion within a rock layer.
10. Some graded beds, especially those resulting from deposition by a fast-moving debris flow, are reversed, which means ___the oldest____ material is at the top instead of at the bottom.
From the principle of superposition of strata, we know that the oldest layer is at the bottom of the sequence and the youngest is on top.

After the initial push, the rock will keep moving forever at constant velocity (constant speed in a straight line)
Explanation:
We can answer this question by using Newton's first law of motion:
"An object at rest (or in motion at constant velocity) will stay at rest (or will keep moving at constant velocity) unless acted upon unbalanced forces" (Law of inertia)
In this problem, we have a rock in a place very far from any force that can act on it. This means that there are no unbalanced force acting on it, so the rock will keep its state of motion forever.
In this situation, the rock is initially thrown by the astronaut. After the initial push, which accelerates the rock up to a certain velocity, there will be no more forces acting on the rock. This means that the rock will continue moving at a constant velocity forever, so at a constant speed in a straight line.

As we know that equivalent resistance of a capacitor for an AC circuit is given as
so here for an AC circuit capacitor will provide less resistance to AC component of the current
While for DC as we know it has ZERO frequency
so we will have large resistance
so here we will have to use capacitor as a filter circuit which will separate AC component of current from the DC current
So correct answer will be
CAPACITOR
Final answer:
A diode is the component used to convert alternating current (AC) to direct current (DC), often arranged in a configuration known as a rectifier.
Explanation:
The component used to change alternating current (AC) to direct current (DC) is a diode. A diode is a semiconductor device with two terminals, typically allowing the flow of current in one direction only. In the case of converting AC to DC, a configuration known as a rectifier, often built with diodes, is used. This rectifier changes the AC, which is current that shifts direction, into DC, which is current that flows consistently in one direction.

3. Practice presenting in front of a mirror
Explanation;
Like scientific papers, oral presentations at a conference or internal seminar are for sharing your research work with other scientists. They, too, must convince the audience that the research presented is important, valid, and relevant to them.
Planning a presentation involves a comprehensive assessment of the speaking situation. It is important to know the purpose of the presentation, know the audience and also where the presentation will take place, among other important aspects.
Answer:
The correct answer is option 2. Practice presenting in front of friend or family
Explanation:
Generally while making an oral presentation three things are very vital-
a) Cover all the vital points of the research work presented through oral presentation thus writing all the points on a piece of paper is must.
b) One must use appropriate body gesture while giving the presentation , thus practicing in front of mirror is also a required exercise
c) The presenter must be able to deliver his/her presentation in the stipulated time period thus timing the presentation is also important.
Since mirror practice is sufficient to work on body language, eye contact with the audience and gesture, thus there is no need to practice in-front of friend or family.
