Answer:
Explanation:
Be M1 and M2 the two massive objects and m the third one
The gravitational force over the third object at the beginning is zero (assuming that the position of the third object is x=0)

when the third object is displaced we have that the new position is x=Δx. Hence

I attached a scheme of the system
I hope this is useful for you

Answer:
i found this on google "A universal gate is a gate which can implement any Boolean function without need to use any other gate type. The NAND and NOR gates are universal gates. In practice, this is advantageous since NAND and NOR gates are economical and easier to fabricate and are the basic gates used in all IC digital logic families.

Answer:
Velocity of the wave is 1.7 m/s
Explanation:
As we know that the frequency of the wave is defined as the number of waves crossing a fixed point per second
So here we will have


Also we know that the distance between two consecutive crest or two consecutive trough is known as wavelength
So here the wavelength of the wave is given as

now we have



Divide 3500km by 3h (according to the equation v = d/t) and you get 1167km/h.
