That they sometimes explode?
Speed is the magnitude of velocity.
Velocity depends on both magnitude as well as direction.
Since speed is constant, direction of the object must be changed to make velocity not constant or to make velocity variable.
Hope this helps, have a great day ahead!
Answer: When a material is heated or cooled, two changes may happen to the particles within the material: Chemical bonds between the particles may form, break or stretch. There is a change in the chemical potential store of energy in the material. The material will heat up or cool down as the particles within it gain or lose speed.
Explanation:
Answer:
Length (L2) = 0.51m
Wavelength of string (∆) = 1.02m
Wavelength of sound produced = 0.7795m
Explanation:
Using the equation L1F1 = L2F2
L1 = 0.68m, F1 = 330Hz, F2 = 440Hz
Therefore, (0.68m)(330Hz) = (L2)(440Hz)
L2 = 0.68m × 330hz/440hz
L2 = 0.51m
0.68m - 0.51m = 0.17m from the but
B. ∆ = 2×length (L2)
∆ = 2(0.51) = 1.02m
C. Frequency (f) = 440Hz
V = ∆f
343m/s =∆×440hz
∆ = 343m/s/440hz
∆ = 0.7795m
Answer:
The magnitude of the magnetic field at the origin is .
Explanation:
Given :
50-A wire is in the x-z plane and is 5 m from the z axis.
Also , 40-A wire is in the y-z plane and is 4 m from the z axis.
Now , since both the wire are perpendicular to each other .
Therefore , magnetic field are also perpendicular to each other .
Magnetic field at origin due to wire 1 is :
Magnetic field at origin due to wire 2 is :
Now , therefore net magnetic field is :
Putting value of
We get ,
Therefore, the magnitude of the magnetic field at the origin is .
