Answer:
Calcium
Explanation:
The ability to be hammered into sheets is known in chemistry as malleability. One of the properties of metals is that metals are malleable. All metals thus have a common property that they can be hammered into sheets used in diverse applications. We can see diverse thin sheets of metals around us used to diverse purposes. This is a vary important property of metals that amplify its importance in materials science.
Of all the options listed, only calcium is a metal. Since nonmetals and metalloids can not be hammered into sheets, nitrogen, silicon and fluorine can not be hammered into sheets. Calcium, being a metal can be hammered into thin sheets.
Question:
Options
1) Nitrogen
2) Silicon
3) Fluorine
4) Calcium
Answer:
The correct option is;
4) Calcium
Explanation:
We analyze each of the elements as follows;
Nitrogen is a gas at room temperature, therefore it cannot be hammered into sheets
Silicon is a brittle non-metal, that breaks when struck
Fluorine is a gas at room temperature, therefore it cannot be hammered into sheets
Calcium is a soft, solid silvery-white, metallic element that is ductile, hence, it can be beaten into very thin sheets.

You may think of changes in climate occurring as you go north or south. This climber stayed at the same latitude and went up. What explains the difference in temperature and climate between the top and bottom of Mt. Kilimanjaro? Please explain in 3-5 sentences thank you for 81 points
Answer: I'm not really sure but I think its dew to the different heights and tempura going up and down and the flow of wind.
Explanation:
Answer:
Mountains make it possible for snow to be found at the equator. Why does the temperature become colder the higher up a Mountain? Generally the climate on mountains get progressively colder with increased altitude (the higher up you go).

Where is the DNA stored in a cell?
Answer: nucleus
Explanation:
Refer to the question above to help answer this question. If the students were to redo their experiment with the water and the antiacid tablet, what would you recommend they do in order to show that the mass was conserved in that chemical reaction.
a. They should put a cover on the beaker so nothing can escape during the experiment.
b. They should use two antiacid tablets instead of one.
c. They should use more water.
d. They should get a new scale and double check their measurements.

What is an ellipse please help)
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.
Maybe they might use that math thing for Science.
When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s
kinetic energy is given as
What does net force mean when you dealing with forces
Answer:
The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.
The net force is vector sum of all the forces that act upon an object.
