A 2.3 m -long wire carries a current of 8.6 A and is immersed within a uniform magnetic field B⃗ . When this wire lies along the
Volgvan

Answer:

Explanation:

Given that :

The current I = 8.6 A

The length vector L = 2.3 m i

The force vector is = -2.0 j N

When L = 2.3 m i ; the

Force vector F = (2.0 i - 4.8 k) N

Compute the components of the magnetic field as follows:

F = I(L*B)

Replacing 8.6 A for I ; -2.0 j N for F & 2.3 m i for L

-2.0 j N = (8.6 A) (2.3 m i *(B_xi + B_yj+B_zk)

-2.0 j N = 19.78B_z \ and  \ 0 = 19.78B_y

B_z = -0.1011 T  \ and \ B_y = 0

However in y direction ; we have :

(2.0 i - 4.8 k) = 8,6 A (2.3 mi*(B_xi+B_yj+B_zk)

- 2.0 = 19.78 B_z \ and \ -4.8 = 19.78 B_x

B_z = -0.1011 T \ and \ B_x = -0.2427T

Hence, the component of magnetic field is as follows:

B_x = -.02427T \ ; B_y = 0 T \  ; B_z =  - 0.1011 T)

Một sóng cơ học có tần số 50hz lan truyền dọc theo một sợi dây rất dài biết rằng sau 5 giây sóng truyền được 1 đoạn 25m dọc theo
Oliga [24]

Answer:

10 cm

Explanation:

Được

Tần số = 50 hertz

Khoảng cách đã đi = 25 m

Thời gian đi quãng đường 25 m = 5 giây

Tốc độ của sóng = 25/5 = 5 mét trên giây

Như chúng ta biết

Bước sóng = Vận tốc / tần số

Bước sóng = 5 mét trên giây / 50 trên giây

Bước sóng = 0,1 m = 10 cm
