4.A 31-cm long conducting wire of 9-g carrying 7- A current is placed in a uniform magnetic field. What are the strength and dir
Anika [276]

Answer

Given,

Length of the wire,L = 31 cm = 0.31 m

mass of the wire, m = 9 g = 0.009 Kg

Current in the wire,I = 7 A

Magnetic field strength, B= ?

Equating magnetic force to the weight of the wire.

BIL = m g

B=\dfrac{m g}{IL}

B=\dfrac{0.009\times 9.81}{7\times 0.31}

B = 0.0407 T

For Force to be upward magnetic field direction should be outward of the plane of paper.

After an initial race George determines that his car loses 35 percent of its acceleration due to air resistance travelling at 38
ddd [48]

Answer:

64.2 m/s

Explanation:

We are given that

Speed ,v=38 m/s

We have to find the maximum speed when his car reach on flat ground.

Using dimensional analysis

F_{res}\propto v^2

If 35% acceleration reduced by F(res) at 38 m/s

Then, 100% acceleration  can be reduced  by F(res) at v' m/s

\frac{F_1}{F_2}=\frac{v^2}{v'^2}

v'^2=\frac{F_2}{F_1}v^2

v'=v\sqrt{\frac{F_2}{F_1}}

Substitute the values

v'=38\times \sqrt{\frac{100}{35}}

v'=64.2 m/s

Hence, the maximum speed when his car can reach on flat ground=64.2 m/s
