Answer:
10 A
Explanation:
τ = Maximum torque of the loop = 9 mN
N = Number of turns in the loop = 50
a = side of the loop = 15 cm = 0.15 m
A = Area of the loop = a² = 0.15² = 0.0225 m²
B = magnitude of magnetic field = 0.800 T
i = magnitude of current in the loop
Maximum torque of the loop is given as
τ = N B i A
Inserting the values
9 = (50) (0.8) (0.0225) i
i = 10 A
Answer:
An unbalanced force can change an object's motion. An unbalanced force acting on a still object could make the object start moving. An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving.
The Moon always rotates about the Earth in its orbit. The position of the Earth, moon and sun during a new moon is Earth is in between Sun and Moon.
<h3>What is new moon?</h3>
When moon has travelled for 14 days, it starts its journey again for the next 14 days. The journey starts from the new moon to the full moon. The position of new and full moon is the same. At this time, the Earth is in between the Sun and the Moon.
Thus, the position of the Earth, moon and sun during a new moon is Earth is in between Sun and Moon.
