Where is the diffraction angle in radians, 2 is the wavelength, and L is the width of the gap in the barrier. Radians
were then converted to obtain the diffraction angles in degrees. Now verify your calculations.
The predicted angle of diffraction with a 3 cm wavelength was ( degrees.
The predicted angle of diffraction with a 4 cm wavelength was ( degrees.
The predicted angle of diffraction with a 5 cm wavelength was
degrees.

what are the statements? x

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
