4 cars = 16 students
? cars = 36 students
let x be the number of cars for 36 students
4 • 36 = 16 • x
144 = 16x
144/16 = x
9 = x
It requires 9 cars for 36 students.
//Hope it helps
Answer:
1
Explanation:
Its 1 since the shape of it is more downwards which results the reflection going downwards.
Answer:
kinetic energy (K.E) = 5.28 ×10⁻¹⁷
Explanation:
Given:
Mass of α particle (m) = 6.50 × 10⁻²⁷ kg
Charge of α particle (q) = 3.20 × 10⁻¹⁹ C
Potential difference ΔV = 165 V
Find:
kinetic energy (K.E)
Computation:
kinetic energy (K.E) = (ΔV)(q)
kinetic energy (K.E) = (165)(3.20×10⁻¹⁹)
kinetic energy (K.E) = 528 (10⁻¹⁹)
kinetic energy (K.E) = 5.28 ×10⁻¹⁷
Answer:
B. Chemical changes involve the formation of a new substance.
Explanation:
They can both release energy, both can be measured, and chemical changes can be caused by oxygen, so I believe it would be B.
