A 15.0 cm diameter circular loop of wire is placed with the plane of the loop parallel to the uniform magnetic field between the
velikii [3]

Answer:0.0144 tesla

Explanation:

Magnetic field strength is the same as Magnetomotive force

B= I/2πr

B=magnetic field strength

I=current

r=radius=0.15/2=0.75m

Area=πr2= 1.77m2

torqueT= NIABsin theta

B= T/NIABsin theta

B=0.135/1 * 5.3 * 1.77 *sin90

B=0.0144 tesla

A small artery has a length of 1.10 × 10-3 m and a radius of 2.50 × 10-5 m. If the pressure drop across the artery is 1.15 kPa,
levacccp [35]

Answer:

7.69533\times 10^{-11}\ m^3/s

Explanation:

P = Pressure difference = 1.15 kPa

r = Radius = 2.5\times 10^{-5}\ m

\eta = Viscosity of liquid = 2.084\times 10^{-3}\ Pas

l = Length of artery = 1.1\times 10^{-3}\ m

From Poiseuille's equation we have

Q=\frac{\pi Pr^4}{8\eta l}\\\Rightarrow Q=\frac{\pi 1.15\times 10^3\times (2.5\times 10^{-5})^4}{8\times 2.084\times 10^{-3}\times 1.1\times 10^{-3}}\\\Rightarrow Q=7.69533\times 10^{-11}\ m^3/s

The flow rate of blood is 7.69533\times 10^{-11}\ m^3/s

As a van travels along a level stretch of road with constant speed, most of the power developed by the engine is used to compens
babymother [125]

Answer:

64.10937 N

Explanation:

s = Displacement

v = Velocity

F = Force

Converting hp to W

2.75\times 746=2051.5\ W

Work

W=F\times s

Power

P=\frac{W}{t}\\\Rightarrow P=\frac{F\times s}{t}

Now

\frac{s}{t}=v

So,

P=F\times v\\\Rightarrow F=\frac{P}{v}\\\Rightarrow F=\frac{2051.5}{32}\\\Rightarrow F=64.10937\ N

The friction force acting on the van is 64.10937 N
