The answer is 509 m.
Let point B be 253 m from point A. Let point C be 64 s away from point B.
Let d1 be the displacements from point A to point B and d2 and be the displacements from point B to point C
Step 1. Calculate the displacement from the point B after 64 s.
Step 2. Calculate the displacement from the point A by summing up two distances (d1 and d2).
Step 1.
v = d2/t
v = 4 m/s
d2 = ?
t = 64s
____
4 = d2/64
d2 = 64 * 4 = 256 m
Step 2:
d = d1 + d2
d1 = 253 m
d2 = 256 m
d = 253 + 256 = 509m
Answer:
Physics is important in our daily life because it deals with daily objects we need like light, electricty and sound. Without physics, we cant have the ability to see because lights wont be a thing, we cant use phones, cars and such because they wont work without electricty, you wont be able to listen to your favourite band without sound!
When an atom loses a neutron it become an isotope. Isotopes have the same number of protons and electrons, but a different amount of neutrons.
