Two forces F1, and F2 (and no other forces) act on a particle P causing it to move from rest through a distance of 2 m. Find the work done by the resultant force if F = i- j (N) and F2 is of magnitude 10 N and acts in the direction of 4i + 3j.​

How many neutrons does element x if it’s atomic number is 28 and its mass number is 87

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
