Answer:
Transformers do not allow DC input to flow through. This is known as DC isolation. This is because a change in current cannot be generated by DC

Answer:
17640
Explanation:
Power = workdone/time
Power = (force x displacement)/time
Power = (mg x 60)/60
Power = (1800 x 9.8 x 60)/60
=> power = 17640 watt
Answer: fourth option 1.2 × 10³ joules
Explanation:
1) kinetic energy is calculated as the half of the product of the mass times the square of the speed:
=> KE = (1/2) m × (v)²
2) you know the mass after the collision and the speed so you have all the data fo find the numerical value of the expression for KE:
m = m1 + m2 = 200 kg + 250 kg = 450 kg
KE = (1/2) × 450 kg × (2.3 m/s)² = 1,190.25 joules ≈ 1200 joules = 1.2 × 10³ joules, which is the last option of the list.
