Answer:
16
Explanation:
The formula for the force of attraction between two charges is , where k is a constant, is the first charge, and is the second charge. As you can see, if the radius or distance increases by 2, the force decreases by 4 because it grows exponentially. However, if the charge of one of the particles increases by 2, the force between the two also increases by 2. Therefore, the new force will be 8*2=16. Hope this helps!
Answer: What is the acceleration of an object that moves at constant velocity? Acceleration is Zero
What is the net force on the object in this case? The ner force is also Zero
Explanation: If the velocity is constant means that the acceleration is zero, from Newton second law is clear that net force is also zero
Fnet= m* a as v is constant a=0 this Fnet is zero.
The arrows in models of magnetic and electric fields show both their magnitude and direction.
In Physics, a vector refers to a quantity that has both magnitude and direction. Hence, a vector always points in a given direction. The direction in which the arrow points is the direction of the vector in space.
In models of magnetic and electric fields, field vectors depicted by arrows because they represent both their magnitude and direction. The length of the arrow shows magnitude.

Answer:
Sonic boom is an impulsive noise similar to thunder. It is caused by an object moving faster than sound -- about 750 miles per hour at sea level. An aircraft traveling through the atmosphere continuously produces air-pressure waves similar to the water waves caused by a ship's bow.
