Answer:
a reference point allows you to determine the motion of an object :)
example: when your in a car and u look out the window and your moving fast than the car next to you. It seems that way because the car next to you is actually moving much slower.
Plot a graph, constant speed of movements represented as straight lines. Time on X axis (seconds) and position on Y axis (metres) , calculated by moving, e.g 4metres in a second.
Answer:
F = 3750 N
Explanation:
Given that,
Pressure, P = 150 Pa
Area, a = 25m²
We need to find the force applied. We know that, pressure is equal to the force acting per unit area. It can be given by :
So, the required force is 3750 N.
Answer: There are 7 protons, 7 neutrons, and 7 electrons in the Nitrogen Atom.
Explanation: The atomic number is the number of protons and the number of neutrons would be the mass number minus the atomic number or 14 - 7 = 7. The electrons would be 7 because it has a neutral charge and that means that the electrons would be the same as the protons.
