An object's momentum is the product of its mass and its velocity:
p = mv
p is its momentum, m is its mass, and v is its velocity.
Given values:
p = -80kg×m/s
m = 8kg
Plug in these values and solve for v:
-80 = 8v
v = -10m/s
Choice D
<span>In Thomson experiment, why was the glowing beam repelled by a negatively charged plate, because the glowing beam was negatively charged. The glowing beam particles were attracted to the positive plate.
</span><span>J.JThomson proved that the cathode rays produced a stream of negatively charged particles called electrons. </span>
They are formed when two plates collide, either crumpling up and forming mountains or pushing one of the plates under the other and back into the mantle to melt. Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts.
Answer:
yes. can always be separated
They're made up of more than one substance.
They're readily available in nature.
Explanation:
A composite material or substance is one that is made up of more than one substance.
A composite is used specifically for a purpose which the two desired materials can provide by combining them.
- Composites given better material integrity compared to their components.
- A composite is produced in order to augment the properties of materials.
- The product has unique properties different from those combining.
- Composite materials are readily available in nature.
- For example, wood is a composite structure in plant.
