Which element is most likely to have the ability to be hammered into a thin sheet?(Nitrogen, Silicon, Fluorine, Calcium)​

Answers

Answer 1

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.

Answer 2

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.

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.

Answers

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
