Answer:

Acceleration

Explanation:

The choice from the given option which is not a force is acceleration.

Acceleration is defined as the rate of change of velocity of a body with time;

Acceleration = $\frac{change in velocity}{time}$

Force is a pull or push on a body. The product of mass and acceleration is force.

Thrust is a form of force
Gravity is a force acting on bodies with masses.
Friction is a force that opposes motion,

A student holding a 324Hz tuning fork approaches a wall at a speed of 6ms^(-1). The speed of sound in air is 336ms^(-1). What fr

Mashutka [201]

The frequency the student detect from waves omitted from the fork and waves coming from the wall is 348.1 Hz.

<h3>Frequency detected by the student</h3>

The observed frequency is determined by applying Doppler effect;

f' = f₀(v + v₀)/(v)

where;

f' is the observed frequency
v is speed of sound
v₀ is the source speed
f₀ is the original frequency

f' = 342(6 + 336)/(336)

f' = 348.1 Hz

Thus, the frequency the student detect from waves omitted from the fork and waves coming from the wall is 348.1 Hz.

You're driving your new sports car at 85 mph over the top of a hill that has a radius of curvature of 525 m.

Bumek [7]

Explanation:

It is given that,

Speed of the sports car, v = 85 mph = 37.99 m/s

The radius of curvature, r = 525 m

Let $W_N$ is the normal weight and $W_A$ is the apparent weight of the person. Its apparent weight is given by :

$W_A=mg-\dfrac{mv^2}{r}$

So, $\dfrac{W_A}{W_N}=\dfrac{mg-\dfrac{mv^2}{r}}{mg}$

$\dfrac{W_A}{W_N}=\dfrac{g-\dfrac{v^2}{r}}{g}$

$\dfrac{W_A}{W_N}=\dfrac{9.8-\dfrac{(37.99)^2}{525}}{9.8}$

$\dfrac{W_A}{W_N}=0.719$

$\dfrac{W_A}{W_N}=71.9\%$

Hence, this is the required solution.
