Answer:
1. b. The door is exerting a centripetal force on you that balances the centrifugal force of the turn.
2. b. There is no net force acting on the object.
Explanation:
1. This is because as you move to the right due to the centrifugal force of the turn, a corresponding centripetal force acts on you due to the door which does not allow you fall out of the car since,<u> the door is exerting a centripetal force on you that balances the centrifugal force of the turn. </u>
So, the answer is b
2. This is because, since the object moves at a constant speed and thus does not accelerate, no net force can act on it since, a net force would imply that the object accelerates. Note that a constant speed does not imply that no force acts on it. It only shows that the resultant or net force is zero since the object does not accelerate.
So, <u>there is no net force acting on the object. </u>
So, b is the answer.
Resolution in this sentence refers to a solution to the problem
<span>Resistance of automobile light is equal to 12 ohms.
</span>Resistance = Voltage / Current
where
Voltage = 12 volts
Current = 1.0 Amperes
Resistance = 12 volts/ 1.0 amperes
Resistance = 12 ohms.
Automobile light has 12 ohms resistance when it is connected to 12volts battery with 1.0 ampere current.
Answer:
The correct answer is option B.
Explanation:
f = focal length
P = -5.5 D (negative power means that lens is concave)
1 m = 100 cm
f = -0.1818 m = -0.1818 × 100 cm= -18.18 cm
v = -18.18 cm
v = 1.8 cm - far point
far point = 1.8 cm - v =1.8 cm - (-18.18 cm) = 19.98 cm
But closest answer from the given options is option B.Hence, 20 cm is the correct answer.
