The seat belt is applying a force in the opposite direction.
Answer:
F = M a = M v^2 / R
If v is increased by three the force will be increased by nine,
C) is correct
Answer:
12
Explanation:
The number of electrons in an atom is always the same as the number of protons, so atoms are electrically neutral overall.
Atoms can lose or gain electrons. When they do, they form charged particles called ions:
if an atom loses one or more electrons, it becomes a positively charged ion
if an atom gains one or more electrons, it becomes a negatively charged ion

Answer:
B) 3.33 m/s²
Explanation:
Given that,
The initial velocity of Juan, u = 10 m/s
Final velocity of Juan, v = 60 m/s
Time taken, t = 15 s
The acceleration is given by the relation
a = v-u/t m/s²
Substituting in the above equation
a = 60 - 10 / 15
a = 3.33 m/s²
Hence, the acceleration of the Juan is, a = 3.33 m/s²
