Uh it's c) 0.5 :), and for some reason i need to write 20 characters to explain it well, okay you need to divide speed/wavelength, that's it

amm1812

Answer:

15 V

Explanation:

Electric potential is given as the product of Electric field and distance. Mathematically:

V = E * r

Where E = Electric field

r = distance = 6m

Electric field, E, is:

E = F / q

Where F = Electric force = 5N

q = Electric charge = 2C

Therefore, electric potential will be:

V = (F * r) / q

V = (5 * 6) / 2

V = 15V

When you cook a marshmallow on a metal poker tool over an open flame, energy is transferred. Identify the three different ways t
ss7ja [257]

When we cook a marshmallow on a metal poker tool over an open flame, there are three ways in which heat energy is transferred: Conduction, convection, and radiation.

<h3>Heat energy transfer</h3>

Heat transfer is the natural transfer of heat from an object with a higher temperature to an object with a lower temperature. Heat transfer can occur in three ways, namely conduction, convection, and  radiation.

  1. Conduction occurs when heat flows from a place with a high temperature to a place with a lower temperature using a fixed heat-conducting medium. Heat transfer from the open flame to the marshmallows via direct fire contact with the marshmallows is an example of conduction.
  2. Convection is the transfer of heat by means of a stream in which the intermediate substance also moves. If the particles move and cause heat to propagate, convection will occur. The hot air rising from the flames burning the marshmallows is an example of convection.
  3. Radiation is heat transfer without a medium. Radiation can also usually be accompanied by light. The direct transfer of heat from the flame to the marshmallow in the form of waves is an example of radiation.

Suppose the initial position of an object is zero, the starting velocity is 3 m/s and the final velocity was 10 m/s. The object
Nookie1986 [14]

Explanation:

We have,

The initial position of an object is zero.

The starting velocity is 3 m/s and the final velocity was 10 m/s.

The object moves with constant acceleration..

The area covered under the velocity-time graph gives displacement of the object. The correct option is "the area of the rectangle plus the area of the triangle under the line".
