Answer:
The bigger one. Ignoring air resistance, they will fall at the same speed, but the bigger one will hit first because it sticks out lower.
Explanation:
The magnitude of the force is F=1.68×10 ^20 N
<u>Explanation:</u>
<u>Given data</u>
q1 =1.5 10 ^6 q2=3.2 10^6 r=1.5
<u>We have the formula</u>
By the coulomb's law
F= K. q1 ×q2 / r²
The K value is given by
8.99 10^9 Nm²/ c²
substitute the values we get,
F= ( 8.99× 10^9 Nm²/ c²) ×(<u>1.5 ×10 ^6</u>)×(<u>3.2 ×10 ^6</u>)/ (1.6 m² )
F=1.68×10 ^20 N
The magnitude of the force is F=1.68×10 ^20 N
Answer:
37 W
Explanation:
Power is the time rate of dissipation or absorbing energy. The power supplied or absorbed by an element is the product of the current flowing through the element and the voltage across the element. Power is measured in watts. If the power is positive then it is absorbed by the element and if it is negative then it is supplied by the element.
Power = voltage * current
For element A: Power = 36 V * -4 A = -144 W
For element B: Power = -20 V * -4 A = 80 W
For element C: Power = -24 V * 4 A = -94 W
For element D: Power = -80 V * -1.5 A = 120 W
For element E: Power = 30 V * 2.5 A = 75 W
The total power developed in the circuit = sum of power through the element = (-144 W) + 80 W + (-94 W) + 120 W + 75 W = 37 W
