many increases and decreases but declined overall
Answer:
Correct answer : v = 50 m/s
Explanation:
The movement described is a free fall with no initial velocity and we will use the following formula:
v = g · t we take that g = 10 m/s²
v = 10 m/s²· 5 s = 50 m/s
v = 50 m/s

Answer:
Period = 7
Group = Actinides group
Family = Actinides Family
Explanation:
uranium found in seventh row or seventh period of the periodic table.
uranium is the member of Actinoides group it is also called Actinide group, And it has element whose atomic is number is 89 to 103. The atomic number of the uranium is 92. So, the uranium element is belongs to Actinide group
Uranium found in actinide family of periodic table, and actinides family has element whose atomic number is greater than or equal to 89 and less than or equal to 103.
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
