Answer:
Explanation:
Given:
Length of a rope,
Position of Canary on the rope from one end,
Position of Grackle on the rope from another end,
Tension in the rope,
linear mass distribution on the rope,
We have for the speed of wave on the string:
<em>For canary to be undisturbed we need a node at this location.</em>
<em>Also, at the end close to Canary there must be a node to avoid any change in pattern of vibration.</em>
So,
the distance between Canary and the closer end must be equal to half the wavelength.
∴Wavelength of wave to be produced = 20 m. This will give us nodes at the multiples of 10 and anti-nodes at the multiples of 5.
Now, frequency:
Answer:
Explanation:
mass of charged particle m = 6 x 10⁻³ kg .
speed of particle v = 4 x 10³ m /s
speed of particle perpendicular to magnetic field = v sin37
= 4 x 10³ sin37
= 2.41 x 10³ m / s
Force on charged particle
= B q v , B is magnetic field , q is charge on particle and v is velocity perpendicular to B
Force = ma
= 6 x 10⁻³ x 8
= 48 x 10⁻³
Force = Bqv
48 x 10⁻³ = 5 x 10⁻³ q x 2.41 x 10³
q = 48 x 10⁻³ / (5 x 2.41)
= 3.98 x 10⁻³C.
Average kinetic energy hope this helps!
Well visual and perceptual are both the way you see things and tactile is touch so it has to be Olfactory
