T = ?
v1 = 0mph
v2 = 60mph
a = 8.7mph/s

Therefore, it takes 6.90 seconds for Jill to accelerate from 0 to 60 miles per hour.
Answer:
129.6 seconds
Explanation:
Given that :
α = 0.0002°c-1
θ1 = 20°C
θ2 = 5°C
Time t = one day ; Converting to seconds ; number of seconds in a day ; (24 * 60 * 60) = 86400 seconds
Let dT= change in time
Using the relation :
dT = 0.5* α * dθ * t
dθ = (20 - 5) = 15°C
dT = 0.5 * 0.0002 * 15 * 86400
dT = 129.6 seconds
During the evacuation of a system containing large amounts of moisture, it may be necessary to prevent freezing by increasing pressure using a gas such as Nitrogen
The scientific name for nitrogen is N, and it is a flavorless and colorless element. The ground beneath our feet contains nitrogen, as does the water we drink and the air we breathe. In fact, nitrogen makes up the majority of the atmosphere on Earth, making up around 78% of the atmosphere.
Nitrogen, which is necessary for plant growth, can be "fixed" by lightning or given to soils through fertilizers. a flavorless gas with no color. The chemical industry depends on nitrogen. It is used to create explosives, nylon, nitric acid, fertilizers, and colors. Nitrogen is always represented as N2 when it is in a gaseous state. It belongs to the group of seven diatomic molecules.

Answer:
PART A: option b. .43nm
PART B: option d. 0.11nm
PART C: option c. The wavelengths of visible light are too long compared to the atomic spacing.
Explanation:
Given data
Wavelength λ = 0.20 nm
Angle θ = 0.8 rad
(a)
wavelength of x-ray to give maximum at the same location
λ₂ = m λ
Here, m = 2 is the interference fringe order.
Substitute the values in the above equation.
λ₂ = 2 × 0.2
= 0.4 nm
Hence, the wavelength of x-ray to give maximum at the same location is 0.4nm
(b)
The crystal plane separation is equal to d
The value of θ is equal to 0.8 rad.
Convert rad into degree as follows:
0.8 rad =
= 144°/π = 45.86°
Solve for d, using equation (1) as follows:
2dsinθ = mλ
d = mλ / 2sinθ
d = (1) 0.17 / 2Sin45.86°
d = 0.17 / 1.9065
d = 0.089 nm
(c)
The visible light can not be used to study the structure of proteins because of the high wavelength of the visible light.
