Answer
given,
Wavelength of the light = 574 nm
distance from the screen = 2.38 m
distance between the second diffraction minimum and the central maximum = 1.82 cm = 0.0182 m
a) Angle of diffraction for the second minimal
θ =
θ =
θ = 0.438°
b) width of slit d is given by
d = 1.5 x 10⁻⁴
Answer:
The net force on the car is 2560 N.
Explanation:
According to work energy theorem, the amount of work done is equal to the change of kinetic energy by an object. If '' be the work done on an object to change its kinetic energy from an initial value '' to the final value '', then mathematically,
where '' is the mass of the object and '' and '' be the initial and final velocity of the object respectively. If '' be the net force applied on the car, as per given problem, and '' is the displacement occurs then we can write,
Given, .
Equating equations (I) and (II),
Answer:
Headlands and bays are created where there are bands of hard and soft rock which meet the coastline at right angles. Softer rock is eroded more quickly and erodes backwards to form bays (which may have beaches). The harder rocks are more resistant to erosion and jut out into the sea to form exposed headlands
Answer:
Evaporation
Explanation:
Evaporation occurs when a liquid changes to a gas. During evaporation, molecules gain enough thermal energy to escape from the liquid surface into the air as water vapor. Water-vapor molecules spread out, breaking completely free of each other, and then disperse or spread out among the other gas molecules in the air.
Hope this helps stay safe

I believe that number 2 is A, not sure though.
