Since it was dropped, it should be the speed of gravity which is 9.8 meters/second
B because the peripartum is the onset depression
Hi there!
Use the following equation: (Newton's Second Law)
∑F = ma, where:
∑F = net force (J)
m = mass (kg)
a = acceleration (m/s²)
Plug in the given values:
∑F = 1500 · 40 = <em>60,000 J</em>
Answer:
Explanation:
Given:
dI/dt = 6.21 A/s
n = N/l
= 100 turns/cm
= 100 turns/cm × 100 cm/1 m
Radius, r = 14.7 cm
= 0.147 m
Inductance, L = uo × n^2 × A × l
L/l = 4pi × 10^-7 × (100 × 100)^2 × pi × 0.147^2
= 8.53 H
Emf, E = L × dI/dt
E/l = L/l × dI/dt
= 8.53 × 6.21
= 52.98 V/m
=
Answer: B
Explanation: I can tell the block weights more since the water went down
