Question

$car \: accerates \: from \: 6ms {}^{ - 1} {16}^{ - 1} in \: 10 \: seconds. \: calcuate \: \: \\ (a)accelration \\ (b)distance \: covered \: by \: car \: in \: that \: time$
​

Answer 1

Answer:

Answer:

$acceleration \: = \frac{v - u}{t}$

$a \: = \frac{16 - 6}{10}$

$a \: = 1 \: \frac{m}{s {}^{2} }$

$v {}^{2} - u { }^{2} = 2as$

$256 - 36 = 2 \times 1 \times s$

$s = 110m$

Answer 2

Answer:

A magnetic dipole is the limit of either a closed loop of electric current or a pair of poles as the size of the source is reduced to zero while keeping the magnetic moment constant. It is a magnetic analogue of the electric dipole, but the analogy is not perfect.
