"Two long parallel wires 24.0 cm apart carry currents of 3.0 A and 8.0 A in the same direction. How far from the wire carrying 3
avanturin [10]

Answer:

6.5454 m

Explanation:

Let the distance from the wire carrying 3 A current is x

Then the distance from the the carrying current 8 A is 24-x

We know that magnetic field due to long wire is given by B=\frac{\mu _0i}{2\pi r}

It is given that magnetic field is zero at some distance so

\frac{\mu _0i_1}{2\pi x}=\frac{\mu _0i_2}{2\pi (24-x)}

Here i_1=3\ A \ and\  i_2=8\ A

So \frac{3}{x}=\frac{8}{24-x}=6.5454\ m

What is the speed of a wave with a wavelength of 10 mm and a frequency of 5.0 Hz?
sleet_krkn [62]
Speed = wavelength × frequency
speed = 10/1000 × 5.0
speed = 0.001 × 5.0
speed = 0.005m/s

A new spacecraft is built with an engine that is able to produce constant acceleration of 1g, where g = gravity’s acceleration o
QveST [7]

given that acceleration due to gravity is g = 10 m/s^2

speed of the rocket will reach to 0.9c

v_f = 0.9* 3 * 10^8 = 2.7 * 10^8 m/s

now by kinematics

v_f = v_i + a*t

2.7 * 10^8 = 0 + 10*t

t = 2.7*10^7 s

Part b)

distance traveled by it in above time

d = v*t + \frac{1}{2}at^2

d = 0 + \frac{1}{2}*10*(2.7*10^7)^2

d = 3.645 * 10^{15} m

so this is the distance covered by the object
