Composition Is the property
Their combined speed will be 1m/s
Given the following parameters;
- The velocity of the first hockey player is 1m/s.
- The velocity of the second hockey player is 2m/s.
If the player collides and stick together, the combined speed is expressed as;
- Combined speed = differences in velocity
- Combined speed = 2m/s - 1m/s
- Combined speed = 1m/s.
Hence their combined speed will be 1m/s

<h2>
Answer: False</h2>
Explanation:
This sentence is the description of the mechanical energy.
In this sense, the mechanical energy of a body or a system is that which is obtained from the speed of its movement (kinetic energy) or its specific position (potential energy), in order to produce a mechanical work.
That is to say: The mechanical energy involves both the kinetic energy and the potential energy (which can be elastic or gravitational, for example).
In addition, it should be noted that mechanical energy is<u> conserved in conservative fields and is a scalar magnitude.</u>
Therefore:
<h2>The sum of potential and kinetic energies in the particles of a substance is called <u>Mechanical Energy</u></h2>
The mass of lead required to make a 1.00 cm3 fishing sinker is 11.3g.
What is mass?
Mass is a metric used in physics to express inertia, a fundamental characteristic of all matter. A mass of matter's resistance to altering its direction or speed in response to the application of a force is what it essentially is. The change that an applied force produces is smaller the more mass a body has.
Given :
Density of lead = 11.3 g/cm3
Volume of sinker = 1.00 cm3
One of a substance's attributes is density, which is calculated by dividing the mass by the volume. Mathematically:
Density : Mass / volume
therefore after putting the values,
mass= 11.3g

Increasing the mass of an object increases its momentum.
Explanation:
- Momentum of an object is measured as the quantity of motion done by the object.
- It is calculated using the formula, p = m × v where m is mass of the object and v is the velocity of the object.
- As momentum and mass vary proportionally, as seen in the formula, increasing the mass of an object will also increase its momentum.
