Q: The acceleration of gravity means that for each second that passes, falling objects move 9.8m? A:True
2 answers:
Answer:
False
Explanation:
If the object covers 9.8 m every second then it has a constant velocity of 9.8 m/s
The acceleration implies that there is a change in velocity. With a constant acceleration the velocity will change linearly.
The distance traveled each second will not be a constant, it will be a quadratic function as mentioned above.

Answer:
The magnitude of magnetic field at given point = ×
T
Explanation:
Given :
Current passing through both wires = 5.0 A
Separation between both wires = 8.0 cm
We have to find magnetic field at a point which is 5 cm from any of wires.
From biot savert law,
We know the magnetic field due to long parallel wires.
⇒
Where magnetic field due to long wires,
,
perpendicular distance from wire to given point
From any one wire 5 cm,
3 cm
so we write,
∴
Therefore, the magnitude of magnetic field at given point =
