Crust
Explanation:
The crust is the layer of the earth with the least dense materials. The crust is made up of silicate materials.
- During the early stage in the formation of earth.
- The earth differentiated minerals based on their densities.
- Lighter minerals stayed afloat while the denser ones sank to the core of the earth.
- The core is made up of the most dense metallic minerals.
- As we go deep into the earth density increases.
- Density of crust ranges from 2.-3.3g/cm³
- The core is about 13.8g/cm³ dense.

Answer:
weight is the mass of an object
it is depends on mass of the body.
The correct answer is C.
W=force into distance.
Option B states that "balanced forces act on on object and cause movement in direction of these force" which is against the laws of physics.
Option A is wrong because work is the product of force into distance,its not time.
Option D says that work is distance over time,which is wrong as:
speed=distance/time
So your left with option C
Answer: The correct option is (B) 0.875 Ω.
Explanation:
Equivalent resistance: It is defined as the sum of the all resistance present in the circuit.
There are two conditions:
(1) Resistors in series
Equivalent resistance,
(2) Resistors in parallel
Equivalent resistance,
According to the given circuit, the resistors are in parallel arrangement.
Given:
Thus,
Equivalent resistance will be:
Therefore, the equivalent resistance of the circuit is 0.875 Ω.
Answer:
0.18 amperes
Explanation:
V = 9
R = 50 ohms
I = ?
Formula
V = I * R
Solution
9 = I * 50 Divide by 50. Switch
I = 9 / 50
I = 0.18 amperes.
If you know what a milliampere is then it is 180 ma which is very large for a 9 volt battery to handle
