A farmer pulls on his obstinate mule with 250 N of force to the right. The ground exerts a reaction force to the mule’s resistan

ce of 250 N to the left. What is the net force on the mule system? What is the mule’s acceleration?

0 net force it is exerting an equal and opposite force against the mule. And since the net force is 0 then the acceleration would be 0 too.

A car in an amusement park ride rolls without friction around a track (Fig. P7.42). The hB car starts from rest at point A at a

MrRissso [65]

Answer:

$h>\dfrac{5}{2}R$

Explanation:

Given that

Height = h

Radius = R

From energy conservation

$KE_A+U_A=KE_B+U_B$

At point B

The minimum speed to complete the the circle

$V_B=\sqrt{gR}\ m/s$

So the kinetic energy at point B

$KE_B=\dfrac{1}{2}mV^2$

$KE_B=\dfrac{1}{2}mgR$

$KE_A+U_A=KE_B+U_B$

$0+mgh=\dfrac{1}{2}mgR+2mgR$

Without falling off at the top (point B)

$0+mgh>\dfrac{1}{2}mgR+2mgR$

$mg(h-2R)>\dfrac{1}{2}mgR$

$g(h-2R)>\dfrac{1}{2}gR$

$h>\dfrac{5}{2}R$

57.9 g of gold has a volume of 3 cm³ what is the density of gold in g/ centimeters cubed

Grace [21]

D=m÷v

so density would be 57.9 ÷ 3 = 19.3 g/cm³

One violin creates a sound whose intensity level is 60dB. Find the intensity level of 16 violins, each playing at this intensity

Yanka [14]

Answer:

72.04 dB.

Explanation:

The intensity level of 60dB corresponds to the sound intensity $I$ given by the equation

$60dB = 10log(\dfrac{I}{I_0} )$

where $I_0 = 1*10^{-12}W/m^2$

solving for $I$ we get:

$6 = log(\dfrac{I}{I_0} )$

$10^6 =\dfrac{I}{1*10^{-12}}$

$\boxed{I = 1*10^{-6} W/m^2}$

Now, when 16 violins are playing the intensity $I$ becomes

${I = 16(1*10^{-6} W/m^2)$

which on the decibel scale gives

$dB = 10log(\dfrac{16*10^{-6}}{1*10^{-12}} )$

$dB = 72.04\: dB$ .

Thus, playing 16 violins together gives the intensity level of 72 dB.

Having landed on a newly discovered planet, an astronaut sets up a simple pendulum of length 1.25 m and finds that it makes 419

Zina [86]

Answer:

$g=2406.8m/s^{2}$

Explanation:

firstly we have to find the frequency and then the angular frequency.

The frequency will be:

$f=\frac{419}{60} \\f=6.98Hz$

The angular frequency is:

ω $=2\pi f$

ω $=2*\frac{22}{7} *6.98$

ω $=43.88rad /sec$

Now we can apply simple pendulum relationship

ω $=\sqrt{\frac{g}{l} }$

make g the subject of the formula

$g=w^{2} l\\g=43.88^{2} *1.25\\g=2406.8m/s^{2}$
