The answer is true to your question
Answer:
A) B = 9.425 × 10^(-5) T
B) North direction
Explanation:
A) We are given;
Current in coil; I = 4.5 A
Number of turns; N = 100 turns
Radius;R = diameter/2 = 6/2 = 3 m
Formula for the magnetic field at the center of the coil is given by;
B = (μ_o•N•I)/2R
Where μ_o is a constant = 4π × 10^(-7) H/m
Thus;
B = (4π × 10^(-7) × 100 × 4.5)/(2 × 3)
B = 9.425 × 10^(-5) T
B) The direction of the force on a positive ion in water can be gotten by the application of flemmings right hand rule.
From flemmings right hand rule, we know that;
- The thumb indicates the direction of the motion of the force which is in the north direction.
- The Index finger indicates the direction of the magnetic field which is in the east direction
- The middle finger indicates the direction of magnetic field which is downwards in the west direction.
Therefore, the direction of the force as seen from flemmings right hand rule is in the north direction
Answer:
First Car Avg: Velocity=0.11 m/s
Second Car Avg: Velocity=0.28 m/s
Explanation:
Data
D1 (First Car Displacement)=0.25m
T1 (First Car total time taken)=2.23s
D2 (Second Car Displacement)=0.25m
T2(Second Car time taken)=3.13-2.23=0.9s
Avg: Velocity1=?
Avg: Velocity2=?
Solution
Avg: Velocity1=D1/T1
Avg: Velocity1=0.25/2.23
Avg: Velocity1=0.11 m/s
Avg: Velocity2=D2/T2
Avg: Velocity2=0.25/0.9
Avg: Velocity2=0.28 m/s
My answer -
The condition in the nucleus are likely to result in the nucleus
breaking apart is called the nuclear fission. But if it is the atomic
nucleus that is breaking apart, it should be called as the nuclear
fusion. These things usually can be caused by the decay of the
radioactive and the nuclear reaction.

Happy to help you have an AWESOME!!! day :)
In order to find out if the exponential function represents a growth or a decay, let's look at the number that is base to the exponent x.
If the number is greater than 1, so the function represents a growth, and if the number is less than 1, the function represents a decay.
Since the number is 1.075, the function represents a growth.
To find the % increase, first let's convert the number to percentage, and then subtract 100%:
So the percent increase is 7.5%.
