It is given that the charge of an electron is -1.602x10^-19. When expressed in atomic units, the elementary charge (<span>1.602x10^-19</span>) is equal to the value of unity (1). Since an electron carries a negative charge, the charge should be equal to negative unity, or -1.
Answer: distance = 24 meters
Explanation:
speed = distance / time
distance = speed x time
speed = 160 cm/s = 1.6 m /s [ 100 cm = 1 m, 160 cm = 1.6 m ]
time = 15 s
distance = 1.6 m/s x 15 s = 24 m
Answer:
8.04672 KM
Explanation:
5 miles = 5×1760 yards = 8800 yards
8800 yards = 8800×36 inches = 316800 inches
316800 inches = 316800 x 0.0254 m = 8046.72 m
8046.72 m = 8.04672 kilometers
Answer: x ≈ 36.3 cm
Explanation:
Conservation of momentum during the collision
0.0340(120) + 1.24(0) = (0.0340 + 1.24) v
v = 3.2025 m/s
The kinetic energy of the block/bullet mass will convert to spring potential
½kx² = ½mv²
x = √(mv²/k)
x = √(1.274(3.2025²) / 99.0)
x = 0.363293... ≈ 36.3 cm
The ingredients do not react with or chemically bond to each other.
