Answer:
y = 1.19 m and λ = 8.6036 10⁻⁷ m
Explanation:
This is a slit interference problem, the expression for destructive interference is
d sin θ = m λ
indicate that for the angle of θ = 35º it is in the third order m = 3 and the separation of the slits is d = 4.50 10⁻⁶ m
λ = d sin θ / m
let's calculate
λ = 4.50 10⁻⁶ sin 35 /3
λ = 8.6036 10⁻⁷ m
for the separation distance from the central stripe, we use trigonometry
tan θ= y / L
y = L tan θ
the distance L is measured from the slits, it indicates that the light source is at x = 0.30 m from the slits
L = 2 -0.30
L = 1.70 m
let's calculate
y = 1.70 tan 35
y = 1.19 m
Answer:
First statement: The particles which are displaced is parallel to the direction of energy transport or to the direction the wave travels.
Second statement: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position.
Third statement: wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.
Explanation:
Wave can be defined as a displacement that occurs in a medium, from one point to another. There are two different kinds of waves in physics which includes:
- Longitudinal wave and
- Transverse wave.
In a longitudinal wave, particles are displaced parallel to the direction of energy transport or to the direction the wave travels. There are also different properties which can be used to describe a longitudinal wave and they includes:
- amplitude: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position in a longitudinal wave.
- wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.
Answer:
No.
Explanation:
Centripetal acceleration would make the ball move towards the center of the circle. Centri- means "center", -petal means "towards". But since the ball has its own velocity that is perpendicular to the centripetal force vector, the centripetal acceleration can only change the direction of the velocity. Which means that centripetal acceleration cannot increase the ball's speed.
Answer:
17.8 mAs
Explanation:
The exposure maintenance formula shows that as SID increases, intensity decreases, causing a decrease in film exposure and density. The mAs is directly proportional to the square of the distance. That is as mAs increases, distance increases, and vice versa, in order to maintain image receptor exposure. It is given by:
Given that mAs₁ = original mAs = 40 mAs, D₁ original distance = 60 in, D₂ = new distance = 40 in, mAs₂ = new mAs
The question above is simply a conversion problem. We are asked to convert from Celsius to Fahrenheit and to Kelvin. To convert from Celsius to Fahrenheit, we do as follows:
°F = (°C<span> × </span>9/5) + 32
°F = (30 × 9/5) + 32
°F = 86
From Celsius to Kelvin,
K = °C + 273.15
K = 30 + 273.15 = 303.15
