ValentinkaMS [17]

Answer:

A. Mrŵ² = ųMg

Ŵ = (ųg/r)^½

B.

Ŵ =[ (g /r)* tan á]^½

Explanation:

T.v.= centrepetal force = mrŵ²

Where m = mass of block,

r = radius

Ŵ = angular momentum

On a horizontal axial banking frictional force supplies the Pentecostal force is numerically equal.

So there for

Mrŵ² = ųMg

Ŵ = (ųg/r)^½

g = Gravitational pull

ų = coefficient of friction.

B. The net external force equals the horizontal centerepital force if the angle à is ideal for the speed and radius then friction becomes negligible

So therefore

N *(sin á) = mrŵ² .....equ 1

Since the car does not slide the net vertical forces must be equal and opposite so therefore

N*(cos á) = mg.....equ 2

Where N is the reaction force of the car on the surface.

Equ 2 becomes N = mg/cos á

Substituting N into equation 1

mg*(sin á /cos á) =mrŵ²

Tan á = rŵ²/g

Ŵ =[ (g /r)* tan á]^½

Match the given circuit parts to their appropriate functions. write only the letter of the correct answer on your paper
BaLLatris [955]

Answer:

a. Load.

b. Fuse.

c. Source.

d. Wire.

e. Switch.

Explanation:

An electric circuit can be defined as an interconnection of electrical components which creates a path for the flow of electric charge (electrons) due to a driving voltage.

Generally, an electric circuit consists of electrical components such as resistors, capacitors, battery, transistors, switches, inductors, fuse, etc.

Matching the given circuit parts to their appropriate functions, we have;

a. Load: an appliance or device that uses electricity source like bulbs, computers, television, radio, etc.

b. Fuse: it is a safety device made from materials that easily melt even before the wires carry too much current.

c. Source: it is where electricity came from like batteries and generators.

d. Wire: it is the pathway of electricity from the resources (source) to the load.

e. Switch: it controls the flow of electricity from the source. It is typically used to turn ON or turn OFF a load.

You name binary ionic compounds by naming the first element or the ___ first,
Nuetrik [128]

Answer:

cation, anion

Explanation:

Binary Ionic Compounds- Binary means 2, ionic relates to charges. Therefore binary ionic compounds have TWO elements, with charges that cancel eachother out. The cation (or positive charge) goes before the anion (or negative charge)

example:

NaCl

Na^+1

Cl^-1

Sodium Chloride
