Answer:
Explanation:
When she moved a distance of 1 m from mid point she observe first destructive interference due to two speakers
so we can say that path difference of sound due to two speakers will be equal to half of the wavelength
so path difference is given as
so it will be
now we know that
now frequency of sound is given as
Answer:
this vehichle has 896,000 jules of energy
Explanation: KE=1/2mv squared, KE is Kinetic energy. m is mass and v is velocity
Cause surface currents to move in circular paths.
The advantage is that we do not run out of resources and a disadvantage is that is dangerous when a “human” gets too close and gets sick by the radiation.
Answer:
atoms form bonds by donating, accepting or sharing electrons with other atoms in order to complete their valence shell electrons
