Answer: Heat transfer due to emission of electromagnetic waves is known as thermal radiation.
Explanation: Heat transfer through radiation takes place in form of electromagnetic waves mainly in the infrared region. Radiation emitted by a body is a consequence of thermal agitation of its composing molecules.
Answer:
= 4,574 10⁻⁵ m
Explanation:
The interference pattern for a two slit system is given by
d sin θ = m λ constructive interference
d sin θ= (m + ½) λ destructive interference
In general and also in this case the screen is far from the slits, so the TT-free can approach the TT
tan θ = y / L
Let's replace
d y / L = m λ constructive interference
d y / L = (m + ½) λ destructive interference
Let's start when there is constructive interference
They give us the frequency of light, let's find the wavelength
c = λ f
λ = c / f
λ = 3 10⁸ / 6.32 10¹⁴
λ = 4.7468 10⁻⁷ m
Let's take the opportunity to reduce the SI system
L = 87 cm = 0.87 m
y = 3.16 cm = 0.0316 m
Now we can find the separation of the slits
d = m λ L / Y
d = 3 4.7468 10⁻⁷ 0.87 / 0.0316
d = 3.92 10⁻⁵ m
We already have all the data, now let's use the destructive interference equation and find
d / L = (m + ½) λ
= (m + ½) λ L / d
= (3 + ½) 4.7468 10⁻⁷ 0.87 / 0.0316
= 4,574 10⁻⁵ m
Answer:
Q = 8368 Joules.
Explanation:
Given the following data;
Mass = 50 g
Initial temperature = 30°C
Final temperature = 70°C
Specific heat capacity = 4.184 J/g °C
To find the amount of heat absorbed by the water;
Heat capacity is given by the formula;
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
dt = T2 - T1
dt = 70 - 30
dt = 40°C
Substituting the values into the equation, we have;
Q = 8368 Joules.
The loops must the coil have to generate a maximum emf of 2500 will be 439.
<h3 /><h3>What is the faraday law of electromagnetic induction?</h3>
According to Faraday's law of electromagnetic induction, the rate of change of magnetic flux linked with the coil is responsible for generating emf in the coil resulting in the flow of amount of current.
Given data;
Area,A = 0.239 m²
Angular velocity,ω=373 rad/sec
Magnetic field,B=0.0639 T
Maximum emf,E= 2500V
The formula for the maximum induced voltage is;
E{max} = N × B × A × ω
2500 = N × 0.639 × 0.0239 × 373
N = 438.66
N = 439 \ turns
Hence, loops must the coil have to generate a maximum emf of 2500 will be 439.
