Hey Tori's are the rim of a canyon yells hello toward the opposite side she has an echo hello four seconds later if the speed of

sound is 340 m/s how far away was the canyon wall that produced the echo?

Answer:

The wall is 680 meter away from the person.

Explanation:

Given data

Speed of sound = 340 \frac{m}{s}

Given that Persons said hello toward the opposite side she has an echo hello 4 seconds later means it takes 2 seconds for the sound to reach the wall & again 2 seconds to reach the persons ear.

Therefore the distance between the person & wall is

D = speed × Time

D = 340 × 2

D = 680 meter

Therefore the wall is 680 meter away from the person.

Answer:

B_{net} =(2\times 10^{-5}T/A).(I-25A)

Explanation:

Given :

the distance between the two wires is  = 2 cm

                                                                  = 0.02 m

Current in one of the wire, I = 25 A

Now we know that, when the direction of the current is same that is in one direction , the magnetic field at the mid point in between the two wires will oppose each other.

Therefore we know that

B_{net} = \frac{\mu _{o}\times I_{1}}{2\pi r_{1}}-\frac{\mu _{o}\times I_{2}}{2\pi r_{2}}

                            =\frac{(4\pi \times 10^{-7}T.m/A)}{2\pi (1\times 10^{-2}m)}\times (I-25A)

                            = (2\times 10^{-5}T/A).(I-25A)

A block is given a very brief push up a 20.0° frictionless incline to give it an initial speed of 12.0 m/s. (a) how far along th
shtirl [24]
The incline is frictionless, this means we can use the conservation of energy: the initial kinetic energy of the block
K= \frac{1}{2}mv^2
is converted into gravitational potential energy
U=mgh
where h is the height reached by the block as it stops. By equalizing the two formulas, we get
\frac{1}{2} mv^2=mgh
h= \frac{v^2}{2g}= \frac{(12.0 m/s)^2}{2(9.81 m/s^2)} =7.3 m

However, this is the maximum height reached by the block. The distance along the surface of the plane is given by:
d= \frac{h}{\sin 20^{\circ}}= \frac{7.3 m}{\sin 20^{\circ}}=21.3 m
