An electron with a charge of -1.6 × 10-19 coulombs experiences a field of 1.4 × 105 newtons/coulomb. What is the magnitude of th
kipiarov [429]

Answer:

2.24 \times 10^{-14} Newtons

Explanation:

Magnitude of charge on the electron = q = 1.6 \times 10^{-19} Coulombs

The negative sign in the question statement indicates that the charge is negative.

Magnitude of Electric Field experienced by the electron = E = 1.4 \times 10^{5} Newtons/Coulomb

Magnitude of Force on the electron = F = ?

The relation between the charge, electric field and the force on the charge because of electric field is given by:

E=\frac{F}{q}

From here we can write:

F = qE

Using the values, we get:

F = 1.6 \times 10^{-19} \times 1.4 \times 10^{5}\\\\ F = 2.24 \times 10^{-14}

Thus, the magnitude of the electric force experience by the electron would be 2.24 \times 10^{-14} Newtons

This is the phase of matter with no fixed shape or volume.
LUCKY_DIMON [66]

Answer: Gas

Explanation:

Matter exists in three different phases, they are:

- Solid

the phase of matter with fixed shape, high density and non-moving particles that are held together by strong bonds. Example of solids are stone and chalk

- Liquid

the phase of matter with loosely held particles that are held together and take up the shape of the containing vessel. Examples of liquid are water, orange juice

- Gas

This is the phase of matter with no fixed shape or volume, rather its molecules travel rapidly and randomly within the containing vessel. Examples of gases are ammonia and oxygen

Thus, the phase of matter with no fixed shape or volume is known as gas

Find the distance from a point charge q=100nC where the field intensity is equal to E=6kN/C. please include description of the r
madam [21]

Answer: 0.3872m

Explanation:

q= 100nC -->  100x10^-9 C

k= 9x10^9 Nm^2/C^2

E= 6kN/C --> 600 N/C

r=?

E= K\frac{q}{r^{2} } --> r=\sqrt{\frac{kq}{E} } Despejas "r"

Resuelves

<h3>r=\sqrt{\frac{(9x10^9 Nm^2/C^2)(100x10x^{-9}  C)}{6000N/C} }  (la x es por, no es una variable)</h3><h3>r= 0.3872983346m</h3>

Friction always acts____ and in the ____ direction of the motion of an object ​
Fed [463]

Answer:

Friction force always acts tangent to the surface at points of contact. Friction force acts opposite to the direction of motion. There are 2 types of friction: Static friction: If the two surfaces in contact do not move relative to each other, one has static friction.
