The magnitude of the electric field at the dot is : 10⁴ v/m
<h3>What is electric field?</h3>
Electric field is a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
Given that there are three equipotential lines with equal spacing,we will apply the the relationship between P.D and electric field
Determine the magnitude of the electric field at the dot
change in voltage = E .d
From equation ( 1 )
The magnitude of electric field will be given as
Hence we can conclude that The magnitude of the electric field at the dot is : 10⁴ v/m

Answer:
19 pizzas
Explanation:
1 pizza = 3 boys
=> 56 ÷ 3 = 18.666666666666.. or about 19 pizzas
Bohr's equation for the change in energy is
where
h = Planck's constant
c == the velocity of light
λ = wavelength.
The velocity is related to wavelength and frequency, f, by
c = fλ
Let us examine the given answers on the basis of the given equations.
a. As λ increases, f decreases and ΔE decreases.
TRUE
b. As λ increases, f increases and ΔE increases.
FALSE
c. As λ increases, f increases and ΔE decreases.
FALSE
Answer:
As the wavelength increases, the frequency decreases and energy decreases.
Answer:
The answer is A and C.
Explanation:
Only two factors are relevant when dealing with the gravitational force between two objects - their mass and their distance apart from one another. Gravity's force is proportional to the product of the masses of the two objects and is inversely proportional to the square of the distance between them.
In general,
Power = (energy moved) / (time to move the energy) .
If it's mechanical power, then
Power = (work done) / (time to do the work) .
If it's electrical power, then it can be any one of these:
Power = (volts) x (amperes)
Power = (volts)² / (resistance, ohms)
Power = (amperes)² x (resistance, ohms) .
Whatever kind of energy you're dealing with, power always
turns out to be
(amount of energy produced, used, or moved)
divided by
(time taken to produce, use, or move the energy) .
