Answer

3m/s²

Explanation

u=o

t=25s

v=75m/s

from Newton's first law of motion,

v=u+at

75=0+a(25)

75=25a

a= 75/25

a=3m/s²

What is the least value of an ammeter <br>Is it 1. 0.1<br>2. 0.10<br>3. 0.2<br>4. 0.5

givi [52]

The least value varies depends on ammeter range. In the given question, ammeter range is not mentioned. So, the least value of an ammeter is 0.1 or 0.5 (depends on ammeter range).

<u>Explanation:</u>

The least value of an ammeter is the measure of the smallest number which can be observed in ammeter. So the least value will be varying depending upon its range. If we consider the range of ammeter is 30 A and the scale readings are 10 numbers, then the least value will be 30/10 = 3 A per scale.

So the least value is determined as $\frac{Range of ammeter}{No.of scales}$

So among the given options 0.1 is most suitable for an ammeter with range of 3 A with 30 divisions.

A strip of copper 150 μm thickand 4.5 mm wide is placed in a uniform magnetic field B (vector) ofmagnitude 0.65 T, with B (vecto

kykrilka [37]

Answer:

$V_H=7.3544\times 10^{-6} \,V$

Explanation:

Given that:

thickness of the metal strip, $d=150\times 10^{-6} m$

width of the metal strip, $w=4.5\times 10^{-3}m$

magnitude of the perpendicular magnetic field, $B=0.65 \,T$

current through the strip, $I=23\,A$

charge density, $n=8.47\times 10^{28} \,electrons\,per\,m^3$

Hall voltage is a transverse voltage given by:

$V_H=\frac{I.B}{n.e.d}$

putting the respective values

$V_H=\frac{23\times 0.65}{(8.47\times 10^{28})\times 1.6\times 10^{-19}\times (150\times 10^{-6} )}$

$V_H=7.3544\times 10^{-6} \,V$

Note:

V = E d is used when a charge is moved in a uniform electric field between the two oppositely charged plates, it can't be used here because it is the case of Hall effect where the small voltage develops transverse to the direction of current flow.
