Answer:
we need the graph to answer the question.
The correct answer to the question will be D. a skydiver whose air resistance is equal to that of her weight.
EXPLANATION:
As per the first option, the point is situated outside of the spinning top whose rotational speed is constant. When a body moves in a circular path, its direction is always changed which produces an acceleration. The point present outside of the spinning top moves in a circular path. Hence, it experiences an acceleration.
As per the second option, the car on the freeway is experiencing a net force of -120 N. Here, the car experiences negative acceleration which opposes the motion.
As per the third option, a submerged beach ball whose buoyant force is eight times the force of gravity. Hence, there is net force on the submerged beach ball which will push the ball upward. Hence, the ball experiences an acceleration.
The third option is that the skydiver whose air resistance is equal to that of her weight. Here, the weight of the driver acts in vertical downward direction while air resistance acts in vertical upward direction. The net force acting on the driver is zero. Hence, the acceleration of the driver is zero.
Answer:
Hey hi,
Explanation:
<em>Parachutes are designed to reduce terminal Velocity, so when a person is near to ground will have less speed and the avg speed of person hitting the ground </em><em>with</em><em> parachutes will have 17 mph so which makes the person to easily walk off or fell sleep. </em>

FOR PARALLEL CONNECTION</h3><h3>I1 = 0.12A</h3><h3>I2 = 0.12A </h3><h3>IT =0.24A</h3><h3>FOR SERIES CONNECTION</h3><h3>I1 = I2 = 0.06A</h3><h3>IT =0.06A</h3><h3 />
Explanation:
According to ohms law, V =ITRt
V is the supply voltage
IT is the total current flowing in the circuit
Rt is the total equivalent resistance
Given R1= R2= 100Ω
V= 12V
FOR PARALLEL CONNECTION;
To calculate the total current IT in the battery, we need to calculate the total equivalent resistance RT first. For a parallel connected circuit, the equivalent resistance in the circuit is the sum of the reciprocal of its individual resistances as shown;
RT = 50Ω
from the equation above;
IT = V/RT
IT = 12/50
IT = 0.24A
Note that in a parallel connected circuit, different current flows through the resistances but the same voltage is across them.
IT = I1+I2
For current in resistance R1;
I1 = V/R1
I1 = 12/100
I1 = 0.12A
Since both resitance are the same, they will share the total current equally. Therefore I2 = 0.12A
FOR SERIES CONNECTION;
The total equivalent resistance in the circuit will be the sum of their individual resistances.
RT = 100Ω+100Ω
RT = 200Ω
IT = V/RT
IT = 12/200
IT = 0.06A
Since the resistances are connected in series, the same current will flow through them but different voltages. The total current flowing in the circuit will be the same current flowing through the resistors.
Therefore I1 = I2 = 0.06A
