I have to go with letter B

I'd say D. Here is why.

The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole<span> compared with the </span>south pole<span>. The force is weaker in the middle of the magnet and halfway between the pole and the center. So that means that the south and/or north poles have the strongest magnetic field.</span>

On a rectangle with length 100 m, width 50m and 2 vehicles stationed together. Find the time that they meet given that car A tra
zhannawk [14.2K]

Answer:

T=35.625sec

Explanation:

From the question we are told that:

Length L=100 m

Width W=50m

Velocity of Car A V_A=5m/s

Velocity of Car B V_B=3m/s

Distance traveled by car A before car B moves

d_l=5*3

d_l=15

Therefore total distance traveled at same time interval

D=total\ distance-d_l

Where

Total distance=Perimeter of rectangle

P=2(L+B)

P=2(100+50)

P=300

Therefore

D=total\ distance-d_l

D=300-15\\D=285m

Generally the equation for time taken to meet is mathematically given by

T=\frac{Distance D}{Relative\ speed V_r}

Where

Relative speed = Speed of car A +Speed of car B

V_r=V_A+V_B

V_r=5+3

V_r=8m/s

Therefore the time taken to meet

T=\frac{ D}{ V_r}

T=\frac{ 285}{ 8}

T=35.625sec

Can someone plz tell me how to solve this step by step
avanturin [10]

Answer:

Explanation:

T=2π√l/g

to solve this for l we have to remove the square root in order to finish square root we have to take square on both side so the equation become

T²=4π²l/g

multiplying g on both side

T²g=4π²l

now dividing 4π² on both side

T²g/4π²=l

so l=T²g/4π²

Lady bird [3.3K]
It was thought that no one had studied further in the works of JJ Thomson and John Dalton at their time because there was no sufficient technology to conduct their works. However, their theory was eventually revised when Neils Bohr had theorised the modern atomic structure we know today.
