Explanation:

Men are typically less stable on their feet than women.

The center of gravity is lower in woman in compare to men. It contributes to greater stability to women.

Men are less stable on their feet due to more muscles in the upper part of their body which raises their center of gravity.

Answer:

Tangential speed = 5.72 m/s

Centripetal acceleration = $91.6\text{ m/s}{}^2$

Explanation:

The tangential speed, V, is given by

$v=\omega r$

where $\omega$ is the angular speed and is given by $2\pi f$ (f is the angular frequency or frequency of rotation)

Thus,

$v=2\pi f r = 2\times3.14\times2.55\times0.357 = 5.72\text{ m/s}$

The centripetal acceleration,a, is given by

$a=\dfrac{v^2}{r}$

$a=\dfrac{5.72^2}{0.357} = 91.6\text{ m/s}{}^2$

Consider the magnetic field (B) of a wire with a constant current (I). A Magnetic Field sensor is placed at a radius (r). Will t

iren [92.7K]

Answer:

No, the magnitude of the magnetic field won't change.

Explanation:

The magnetic field produced by a wire with a constant current is circular and its flow is given by the right-hand rule. Since this field is circular with center on the wire the magnitude of the magnetic field around the wire will be given by B = [(\mi_0)*I]/(2\pi*r) where (\mi_0) is a constant, I is the current that goes through the conductor and r is the distance from the wire. If the field sensor will move around the wire with a fixed radius the distance from the wire won't change so the magnitude of the field won't change.

A car approaches a stationary police car at 36 m/s. The frequency of the siren (as heard in the police car) is 500 Hz. What is t

tamaranim1 [39]

The frequency heard by an observer in the moving car as he approaches the police car is 558.6 Hz.

<h3>Frequency hear by the observer</h3>

The frequency heard by the observer is calculated by applying the principle of Doppler effect.

f₀ = f'[(v/v - vs)]

where;

f₀ is the observed frequency
v is speed of sound = 343 m/s
vs is the speed of the source

f₀ = 500[(343 / 343 - 36)]

f₀ = 500(343/307)

f₀ = 558.6 Hz

Thus, the frequency heard by an observer in the moving car as he approaches the police car is 558.6 Hz.
