Radio waves of frequency 1.667 ghz arrive at two telescopes that are connected by a computer to perform interferometry. one portion of the same wave front travels 1.080 m farther than the other before the two signals are combined part a will the two waves combine constructively or destructively? destructively o constructively submit request answer part b calculate the value of m for the path difference between the two signals express your answer as an integer submit request answer

constructively

6

Explanation:

c = Speed of light =

= Frequency = 1.667 GHz

= Path difference = 1.08 m

Wavelength is given by

Path difference is given by

As the integral multiple of wavelength gives path difference the waves will combine constructively.

The value of m is 6

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.

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
