We move a square loop of wire 2.3 cm on a side into a region of uniform magnetic field of 1.5 T with the plane of the loop perpe

vova2212 [387]

Answer:

Force will be $F=8.33\times 10^{-4}N$

Explanation:

We have given side of wire d = 2.3 cm = 0.023 m

Magnetic field B = 1.5 T

Velocity v = 2.1 m/sec

Resistance R = 3 ohm

We know that current is given by $i=\frac{Bvd}{R}=\frac{1.5\times 2.1\times 0.023}{3}=0.02415A$

Power is given by $P=i^2R=0.02415^2\times 3=0.00174watt$

We know that power is also given by $P=Fv$

So $0.00174=F\times 2.1$

$F=8.33\times 10^{-4}N$

Assume your mass is 84 kg. The acceleration due to gravity is 9.8 m/s 2 . How much work against gravity do you do when you climb

KATRIN_1 [288]

M, mass=84 kg
height, h=3.9m
gravity, g= 9.8m/s2
W = F . d
F=force
d=Displacement
W=work done by force
Now by putting the values
F= m g (Acting downward )
d= h (Upward)
W= m g h ( work done against the force)
W= 84•9.8•3.9J
W= 3210.48
Therefore the answer will be 3210.48J.

In most cases, how many electrons does it take to completely fill the

Lyrx [107]

Answer: 2

Explanation:

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

Two men pull on a 31-kg box with forces 8.3 N and 6.6 N in opposite directions.

kykrilka [37]

The resultant acceleration of the box is 0.055 m/s² in the direction of the greater force.

The given parameters:

Mass of the box, m = 31 kg
Two applied forces, = 8.3 N and 6.6 N

<h3>Resultant force on the box</h3>

The resultant force on the box is calculated as follows;

$F_{net} = F_1 - F_2\\\\F_{net} = 8.3 \ N - \ 6.6 \ N\\\\F_{net} = 1.7 \ N$

<h3>Resultant acceleration of the box</h3>

The resultant acceleration of the box is calculated as follows;

$F = ma\\\\a = \frac{F}{m} \\\\a = \frac{1.7}{31} \\\\a = 0.055 \ m/s^2$

Thus, the resultant acceleration of the box is 0.055 m/s² in the direction of the greater force.
