An example of vector quantity thats not a force

1 answer:

6 0

Examples of such quantities include distance, displacement, speed, velocity, acceleration, force, mass, momentum, energy, work, power, etc. All these quantities can by divided into two categories - vectors and scalars. A vector quantity is a quantity that is fully described by both magnitude and direction.

A street light is at the top of a 13.0 ft. tall pole. A man 6.3 ft tall walks away from the pole with a speed of 3.5 feet/sec al

Answer:

$\dfrac{dL}{dt}=5.82 \ ft/s$

Explanation:

given,

street light height = 13 ft

man height = 6.3 ft

speed of the man = 3.5 ft/sec

$\dfrac{H}{L} = \dfrac{h}{l}$

$\dfrac{H}{L} = \dfrac{h}{L-x}$

$\dfrac{L}{H} = \dfrac{L-x}{h}$

hL = H(L-x)

hL = HL-Hx

$L = \dfrac{Hx}{H-h}$

$L = \dfrac{13x}{13-6.3}$

L = 1.94 x

$\dfrac{dL}{dt}=\dfrac{dL}{dx}\dfrac{dx}{dt}$

$\dfrac{dL}{dt}=1.94\times 3$

$\dfrac{dL}{dt}=5.82 \ ft/s$

Gre4nikov [31]

Answer:

correct answer is b

Explanation:

The frequency of a wave depends on the properties of medium density and the elasticity properties change the amplitude depends on the energy carried by the wave, that is, the amplitude is proportional to the height of the wave (oscillation).

Consequently the amplitude of independent of the frequency because it depends on different factors.

Therefore when changing the amplitude the wavelength remains constant

the correct answer is b
