Answer:
= 2630.6 N.m
Explanation:
(FR)x = ΣFx = -F4 = -407 N
(FR)y = ΣFy =-F1-F2 -F3 = -510 - 306 - 501 = -1317 N
(MR)B =ΣM + Σ(±Fd)
= MA + F1(d1 +d2) + F2d2 - F4d3
= 1504 + 510(0.880+1.11) +306(1.11) - 407(0.560)
= 2630.64 N.m (counterclockwise)
The period is the time taken by the wave to complete an oscillation. The frequency of the given sound is 500 Hz.

Period:</h2>
It is the time taken by the wave to complete an oscillation. The frequency is inversely proportional to the time:
![f = \dfrac 1T](https://tex.z-dn.net/?f=f%20%3D%20%5Cdfrac%201T)
Where,
- frequency
- period = 0.002 s
Put the value in the equation,
![f = \dfrac 1{0.002}\\\\f = 500\rm \ Hz](https://tex.z-dn.net/?f=f%20%3D%20%5Cdfrac%201%7B0.002%7D%5C%5C%5C%5Cf%20%3D%20500%5Crm%20%5C%20%20Hz)
Therefore, the frequency of the given sound is 500 Hz.

Answer:
Amp – an ampere a the unit for measuring electricity. The rate at which electricity flows is measured as an electric current. The electric current is measured in Amps.
Hope this helps:)
If correct, can I please have brainliest?
Thank you.
First, let's put 22 km/h in m/s:
![22 \frac{km}{h} \times \frac{1000m}{1km} \times \frac{1h}{3600s}=6.11 \frac{m}{s}](https://tex.z-dn.net/?f=22%20%5Cfrac%7Bkm%7D%7Bh%7D%20%5Ctimes%20%20%5Cfrac%7B1000m%7D%7B1km%7D%20%20%5Ctimes%20%20%5Cfrac%7B1h%7D%7B3600s%7D%3D6.11%20%5Cfrac%7Bm%7D%7Bs%7D%20%20)
Now the radial force required to keep an object of mass m, moving in circular motion around a radius R, is given by
![F_{rad}=m \frac{v^2}{R}](https://tex.z-dn.net/?f=F_%7Brad%7D%3Dm%20%5Cfrac%7Bv%5E2%7D%7BR%7D%20)
The force of friction is given by the normal force (here, just the weight, mg) times the static coefficient of friction:
![F_{fric}= mg \mu_{s}](https://tex.z-dn.net/?f=F_%7Bfric%7D%3D%20mg%20%5Cmu_%7Bs%7D)
Notice we don't use the kinetic coefficient even though the bike is moving. This is because when the tires meet the road they are momentarily stationary with the road surface. Otherwise the bike is skidding.
Now set these equal, since friction is the only thing providing the ability to accelerate (turn) without skidding off the road in a line tangent to the curve:

i have absolutly no idea how to do it but i looked it up and your answer should be B. i could be wrong but thats what the web told me
