Answer: C. Tissue Paper
Explanation:
When we talk about objects that are illuminated by a light source, they are classified according to the amount of light they let through them, as follows:
Transparent bodies: Those who let in almost all the light that incides them. Therefore, the intensity of the incident light is very similar to that transmitted. For example: Clear Glass
Opaque bodies: Those who do not let the light pass. For example: Cream Cheese and Orange Juice
Translucent bodies: Those that let in a portion of the incident light. That is, they let approximately half of the light that falls on them pass through. For example: Tissue Paper
Answer:
7.5 x 10⁻⁸N
Explanation:
Given parameters:
Mass 1 = 60kg
Mass 2 = 75kg
Distance between the bodies = 2m
Unknown:
Gravitational fore = ?
Solution:
The gravitational force between the two bodies can be derived using;
F = 
G is the universal gravitation constant = 6.67 x 10⁻¹¹m³kg⁻¹s⁻²
Insert the parameters and solve;
F = 
= 7.5 x 10⁻⁸N
Answer:
Shadows are formed when an opaque object or material is placed in the path of rays of light. The opaque material does not let the light pass through it. The light rays that go past the edges of the material make an outline for the shadow
Explanation:
When two stars are bound together gravitationally and orbit a common mass, theyre known as B. BINARY STARS.
The elements that is very good in
electrical conductivity are gold and copper: elements that is amphoteric are
copper, zinc, tin, lead, aluminum and beryllium: elements that is gaseous at
room temperature are hydrogen, nitrogen, oxygen, fluorine and chlorine: elements
that is solid at room temperature are all metal except mercury and perhaps some
unseen radioactive elements. Lastly, elements that is brittle are hydrogen,
carbon, nitrogen, oxygen, phosphorus, sulfur and selenium
