The equation for work (W) done by an electric field is:
W = qΔV
where q is the magnitude of the charge and ΔV is the potential difference. The question gives you W and q, so plug n' play to find ΔV:
10 = 2ΔV
ΔV = 5
Answer:
A bowing ball will hit the Earth first before potatoes chips.
Explanation:
While dropping , a bag of potatoes will experience air resistance. A bowing ball also experience air resistances too but it is not affected by it because it has a bigger weight that affect air resistance than potatoes chips. Potatoes chips is affected because it's weight is light and cannot affect air resistance.
Answer:
The forces of attraction are weak in gases.
Explanation:
Solid-state objects are presented as bodies in a definite form; their atoms are often intertwined into narrowly defined structures, which gives them the ability to withstand forces without apparent deformation. They are generally described as hard as well as resistant, and in them, the forces of attraction are greater than those of repulsion. In the crystalline solids, the presence of small intermolecular spaces gives way to the intervention of the bond forces, which place the cells in geometric forms.
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place.
Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container. The attractive forces between particles are strong enough to hold a specific volume but not strong enough to keep the molecules sliding over each other.
Gas – In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles. This means that a gas has nothing to hold a specific shape or volume.
The answer is metabolic heat.
<span>Organisms from the higher trophic levels consume organisms from the lower trophic level and during that process, energy is lost as metabolic heat. Primary producers (plants) contain the greatest amount of energy originally from the sunlight. The next trophic level belongs to primary consumers that consume primary producers. During consumption, energy is lost. Similarly, secondary consumers eat primary consumers and energy is lost again. The highest trophic level is tertiary consumers that contains the least amount of energy.</span>
