Which statements represent properties of intermolecular forces? Select all that apply.

10. A spring whose composition is not completely known might be either bronze (sp gr 8.8) or brass (sp gr 8.4). It has a mass of

frez [133]

The element used is of bronze.

Now before we find out how we got the answer as bronze, firstly let us understand about the device we are talking about. That is, spring.

What exactly is a spring?

A spring is defined as a device that changes its shape in response to an external force, returning to its original shape when the force is removed. If we apply force or pressure in this device, it will change its shape but the moment we stop applying force, it will come back to its original state.

This means that this device is made of something flexible. So, the material it is made up of should also be flexible in nature.

How to find out flexibility of spring?

Flexibility of spring can be found as q = f Q, where f is the spring flexibility.

Here, in this question, we are given the mass of element in air and water. This shows a slight comparison between the mass of that particular element in air and water and thus, we get to know it is trying to draw our attention towards density.

Here, we have mass in air and water, thus, we can determine the density.

From these numbers, we can know that the density given is of bronze.

Hence, the element used is Bronze.

discuss the difference between velocity and speed. identify if these are scalar or vector quantities.

SSSSS [86.1K]

Velocity is the measurement of time of distance between point "A" and "B".
Speed, regards to how far a subject travels in "X" amount of time, disregarding an end and beginning point.

I hope this helps! :)

An automobile travels between the 176.5-m and 295.7-m markers on the highway in 12.4s ...

DaniilM [7]

I've got a great idea ! Let's calculate the car's average speed !

Average speed = (distance covered) / (time to cover the distance)

Distance covered = (position at the end) - (position at the beginning)

= (295.7 m) - (176.5 m) = 119.2 m

Average speed = (119.2 m) / (12.4 s) = 9.61 'm' per 's' .

a 100g ice cube at 0 degrees celsius is placed in 650 grams of water at 25 degrees celsius. When the mixture reaches equillibriu

Artyom0805 [142]

Answer:

The latent heat of fusion of water is 334.88 Joules per gram of water.

Explanation:

Let the latent heat of ice be 'x' J/g

1) Thus heat absorbed by 100 gram of ice to get converted into water equals

$Q_1=100\times x$
