Answer:
Sodium - D) Malleable, soft, and shiny
Sodium is an alkalyne metals that is why they are soft and sodium can cut by knife.
Silicon - C) Has properties of both metals and nonmetals
As we know that those materials have both nonmetals and metals properties are known as metaloid.
Bromine - A) Highly reactive gas
All halogens are so reactive .Because they are high electro negative element.Bromine(Br) is a halogen element.
Argon - B) Nonreactive gas
All noble gases are stable that is why they are not reactive with ant other element.So we can say that noble gas are Nonreactive gas.Argon(Ar) is noble gas.
By definition, the kinetic energy is given by:
Where,
m: mass of the object
v: object speed
Substituting values we have:
Doing the calculations we have
The energy unit is joules
Answer:
the canoe's kinetic energy is:
It would be 2300000 grams.
Answer:
Yes, it will float.
Explanation:
It is given that,
A liquid has a density of 0.85 g/cm³.
We know that, the density of water is 1 g/cm³.
The density of the liquid is less than that of water. If the density of the liquid is less than that of water, it will float in it. Hence, if you pour some of the liquid into a glass of water, it will float.
surface wave is a wave that travels along the surface of a medium. The medium is the matter through which the wave travels. Ocean waves are the best-known examples of surface waves. They travel on the surface of the water between the ocean and the air.
