Answer:
The slit separation is 2.2μm.
Explanation:
Given that,
Wavelength = 635 nm
Angle = 16.6°
Order number = 1
We need to calculate the slit position
Using formula of slit distance
Where, = wavelength
m = order number
Put the value into the formula
Hence, The slit separation is 2.2μm.
Answer: Scalar quantity has magnitude but no direction while a vector quantity has both magnitude and direction.
Explanation:
A scalar quantity is a physical quantity that has magnitude but no direction. Examples are
- temperature, measured in Kelvin
- distance, measured in metres
- speed, measured in metres per second
Vector quantity, on the other hand, is a physical quantity that have both magnitude and direction. Examples are:
- velocity, measured in metres per second (m/s)
- force, measured in newton
- displacement, measured in metres

Answer:
in t seconds, Car A sweep out t radian { i.e θ = t radian }
Explanation:
Given the data in the question;
4 toy racecars are racing along a circular race track.
They all start at 3 o'clock position and moved CCW
Car A is constantly 2 feet from the center of the race track and moves at a constant speed
so maximum distance from the center = 2 ft
The angle Car A sweeps out increases at a constant rate of 1 radian per second.
Rate of change of angle = dθ/dt = 1
Now,
since dθ/dt = 1
Hence θ = t + C
where C is the constant of integration
so at t = 0, θ = 0, the value of C will be 0.
Hence, θ = t radian
Therefore, in t seconds, Car A sweep out t radian { i.e θ = t radian }
