Answer:
a) mass
b) Newtons
c) momentum formula where p stands for momentum, m stands for mass, and v stands for velocity
Hope this helps!
<span>procedure would most likely help determine a chemical property of the substance is : exposing it to a flame to see if it catches on fire
Chemical property is the characteristic that a substance has that differntiate it with another substance. The most common charatcteristics that most scientists wanted to know are :
- It's flamability
- It's radioactivity
- Its toxicity
By throwing the object into fire, we will easily find out these 3 characteristics</span>
c. Electrons flow from sphere B to sphere
___ 13. Most electrical wires are covered with plastic or rubber. The wires are covered with plastic or rubber because
those materials
a. are conductors of electricity. c. are not conductors of electricity.
b. make complete electric circuits. d. make the electricity move quickly.
____ 14. The loss of static electricity as electric charges transfer from one object to another is called
a. friction. b. conduction. c. induction. d. static discharge.
Answer:
Because there is no net force acting o an object in equilibrium.
Explanation:
When object is in equilibrium (either at rest or moving with constant velocity, the net force acting o it is zero.A vector can only have zero magnitude fall of its components are zero this means that all forces acting on the object are balanced.
Answer:
a) θc = 44.21⁰.
b) θc = 41.14⁰
c) θc = 40.36⁰
Explanation:
sin θ = ![\dfrac{n_2}{n_1}](https://tex.z-dn.net/?f=%5Cdfrac%7Bn_2%7D%7Bn_1%7D)
For air,
n₂ = 1
so,
sin θ = ![\dfrac{1}{n_1}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7Bn_1%7D)
(a) fluorite : n₁ = 1.434⁰
sin θ = 0.697 θc = 44.21⁰.
(b) crown glass: n₁ = 1.52⁰
sin θ = 0.657 θc = 41.14⁰.
(c) sodium chloride : n₁= 1.544⁰
sin θ = 0.647 θc = 40.36⁰.
