Answer:
a) 1.34 Volts
b) 3.08 W
c) 2.68 W
Explanation:
Given:
Emf of the cell, E = 1.54 V
current, i = 2.0 A
internal resistance, r = 0.100Ω
(a) Terminal voltage (V) = E - v
where,
v is the potential difference across the resistance 'r'
now,
according to the Ohm's Law, we have
v = i × r
substituting the values in the above equation we get
v = 2.0 × 0.100 = 0.2 Volts
thus,
Terminal voltage (V) = (1.54 - 0.2) = 1.34 V
(b) Now, the Total power (P) is given as
P = E × i = (1.54 × 2.0) = 3.08 W
(c) Power into its load = [terminal voltage, v] * i
= (1.34 × 2.0) = 2.68 W
Answer:
The best description of inertia is an objects velocity
Newton's law applies here because an object in motion (your body) stays the speed that you were going, so if you were hit, your body would keep going when the car is stopped. This causes your body (especially your neck) to whip back and possible break.
