I think its true because they are a soft solid that can be broken down into a liquid... Hope this helps in any way :3
Answer:
3.67 km
Explanation:
Joe distance towards coffee shop is,
![OB=0.40 km](https://tex.z-dn.net/?f=OB%3D0.40%20km)
And the Max distance towards bookstore is,
![OA=3.65 km](https://tex.z-dn.net/?f=OA%3D3.65%20km)
Now the distance between the Joy and Max will be,
By applying pythagorus theorem,
![AB=\sqrt{OB^{2}+OA^{2}}](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7BOB%5E%7B2%7D%2BOA%5E%7B2%7D%7D)
Substitute 0.40 km for OB and 3.65 km for OA in the above equation.
![AB=\sqrt{0.40^{2}+3.65^{2}}\\AB=\sqrt{13.4825} \\AB=3.67 km](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7B0.40%5E%7B2%7D%2B3.65%5E%7B2%7D%7D%5C%5CAB%3D%5Csqrt%7B13.4825%7D%20%5C%5CAB%3D3.67%20km)
Therefore the distance between there destination is 3.67 km.
Answer:
I assume the higher notes would make the rice vibrate more easily, so a flute.
Answer:
a) ![(Qa*g*Vb)-(Qh*Vb*g)=(Qh*Vb*a)\\where \\g=gravity [m/s^2]\\a=acceleration [m/s^2]](https://tex.z-dn.net/?f=%28Qa%2Ag%2AVb%29-%28Qh%2AVb%2Ag%29%3D%28Qh%2AVb%2Aa%29%5C%5Cwhere%20%5C%5Cg%3Dgravity%20%5Bm%2Fs%5E2%5D%5C%5Ca%3Dacceleration%20%5Bm%2Fs%5E2%5D)
b) a = 19.61[m/s^2]
Explanation:
The total mass of the balloon is:
![massball=densityheli*volumeheli\\\\massball=0.41 [kg/m^3]*0.048[m^3]\\massball=0.01968[kg]\\\\](https://tex.z-dn.net/?f=massball%3Ddensityheli%2Avolumeheli%5C%5C%5C%5Cmassball%3D0.41%20%5Bkg%2Fm%5E3%5D%2A0.048%5Bm%5E3%5D%5C%5Cmassball%3D0.01968%5Bkg%5D%5C%5C%5C%5C)
The buoyancy force acting on the balloon is:
![Fb=densityair*gravity*volumeball\\Fb=1.23[kg/m^3]*9.81[m/s^2]*0.048[m^3]\\Fb=0.579[N]](https://tex.z-dn.net/?f=Fb%3Ddensityair%2Agravity%2Avolumeball%5C%5CFb%3D1.23%5Bkg%2Fm%5E3%5D%2A9.81%5Bm%2Fs%5E2%5D%2A0.048%5Bm%5E3%5D%5C%5CFb%3D0.579%5BN%5D)
Now we need to make a free body diagram where we can see the forces that are acting over the balloon and determinate the acceleration.
In the attached image we can see the free body diagram and the equation deducted by Newton's second law
