Answer:
The distance traveled is 44.45 m
Solution:
As per the question:
Average speed, 
Time, t = 1.6 s
Now, convert the average speed into m/s:
1 km = 1000 m
1 h = 
To calculate the distance traveled:
Now,

We know that:
Speed, 
Thus


D) the magnetic field surrounds the wire like a tube , with a counterclockwise field direction...
as it is in the left hand thumb rule
Your answer is C) The speed of sound is higher in solids than in liquids.
Answer:
A.−2.1 × 10^10 N
Explanation:
Using the formula;
E = k Q1Q2/d²
Where;
E is the electrical force
k is the constant
Q1, Q2 are the two charges and
d is the distance between the two charges
Therefore;
E = (9 x 10^9) × (0.0042) × (-0.0050) / (0.0030)²
= -2.1 x 10^10 N
Therefore; electrical force acting between the two charges is -2.1 x 10^10 N.
