Answer:
B: air pressure inside the car drops suddenly
Explanation:
Air in the car drops suddenly because the roof region has lowered pressure than the atmospheric pressure usually varying with the speed of the car
Then the force of gravity between them would be quadrupled and so on but the gravitational force is inversely proportional to the square of the separation distance between the two interacting objects which makes more separation distance will result in weaker gravitational forces
Answer:
Explanation:
The x- and y- components of the velocity vector can be written as following:
Since the angle θ and the magnitude of the velocity is given, the vector representation can be written as follows:
They have a different number of neutrons. What defines what kind of element something is is how many protons it has. Hydrogen will always have 1 proton, because that's what makes it hydrogen. However, it is allowed to have different numbers of neutrons, like 0,1, or 2. They are all in the family of Hydrogen, but they are different isotopes of hydrogen. Hope this helps!
