Why a surface that always have a perpendicular is an equipotential

Physics
1 answer:
Mariulka [41]3 years ago
6 0
Answer:

An equipotential surface is circular in the two-dimensional. Since the electric field lines are directed radially away from the charge, hence they are opposite to the equipotential lines. Therefore, the electric field is perpendicular to the equipotential surface.

A 5000 g toy car starts from rest and moves a distance of 300 cm in 3 s under the action of a single constant force. Determine t
sveticcg [70]

Answer:

3.33 N

Explanation:

First, find the acceleration.

Given:

Δx = 3 m

v₀ = 0 m/s

t = 3 s

Find: a

Δx = v₀ t + ½ at²

3 m = (0 m/s) (3 s) + ½ a (3 s)²

a = ⅔ m/s²

Use Newton's second law to find the force.

F = ma

F = (5 kg) (⅔ m/s²)

F ≈ 3.33 N

Before radiant energy can be converted to thermal energy,it must be changed to what​
vivado [14]

<u>Answer</u>:

The radiant energy is converted into<u> electronic energy</u> before it is transformed into thermal energy.

<u>Explanation</u>:

Radiant energy occurs in the form of "Electromagnetic radiation" and it can pass through all types of matter travelling through the universe. There are numerous advantages of radiant energy. When the radiant energy is incident upon a substance the energy from the sun light excites the electrons in the atom. This sets the atoms in vibrational motion.

Thermal energy is the kinetic energy of moving particles. The thermal energy increases with increase in movement and number of moving particles. When the atoms make a transition from electronically excited state to vibrational state, the energy transfer increases the temperature of the substance. This is felt as thermal energy. Hence, the radiant energy is changed into "electronic energy" before it is converted into "thermal energy".

Les changements d'état de la matière
ale4655 [162]

Answer:

Les changements d'état sont des changements physiques. Ils se produisent lorsque la matière absorbe ou perd de l'énergie. Les processus dans lesquels la matière change entre les états liquide et solide sont la congélation et la fusion. Les processus dans lesquels la matière change entre les états liquide et gazeux sont la vaporisation, l'évaporation et la condensation.

Im not french and I used translate so if it messes up with the translation, I am sorry

A car accelerates from rest at 3m/s2 along a straight road how far has the car traveled after 4s?
murzikaleks [220]

Answer:

24 m

Explanation:

x = 1/2at^{2} + v_{0}t + x_{0}\\a = 3 m/s^{2}\\v_{0} = 0
