When drinking at a private event, you should assume that drinks will be STRONGER THAN NORMAL.

At private events, some hosts have the habit of mixing different drinks together in order to increase the intoxicating power of the drinks. This does not normally happen when one is buying from restaurants or other commercial places. Thus, to be on the safe side, one should always assume that drinks will be stronger when one is attending a private event, this will caution one to drink responsibly in order to avoid intoxication.

A motor is connected to the smaller 0.2 m radius pulley and cable, lifting 150 kg mass. Neglecting the mass/weight of the cable
-Dominant- [34]

Answer:

324.3Nm

Explanation:

The torque is given by the equation

\tau=r\ X\ F

in this case the vectors r and F are perpendicular between them, thus:

\tau=rF

The forces acting on the mass are:

T-Mg=Ma    (1)

where T is the tension of the cable, M is the mass and a is the acceleration.

Furthermore, we have that the acceleration is:

a=\frac{v-v_0}{t}=\frac{10m/s-0m/s}{10s}=1\frac{m}{s^2}

By replacing in (1) we can obtain:

T=Ma-Mg=M(a-g)=(150kg)(1\frac{m}{s^2}+9.8\fac{m}{s^2})=1620N

The force T produces the torque on the pulley, hence:

\tau=rT=(0.2m)(1620N)=324Nm

the answer is 324.4Nm

hope this helps!

Ugo [173]

Answer:

0.08821 kgm²

Explanation:

f = Frequency = 1.7 Hz

m = Mass of lower leg = 5.7 kg

d = Distance of center of mass = 18 cm

g = Acceleration due to gravity = 9.81 m/s²

I = Moment of inertia

Frequency is given by

f=\frac{1}{2\pi}\sqrt{\frac{mgd}{I}}\\\Rightarrow I=\frac{mgd}{(2\pi f)^2}\\\Rightarrow I=\frac{5.7\times 9.81\times 0.18}{(2\pi 1.7)^2}\\\Rightarrow I=0.08821\ kgm^2

The moment of inertia of the lower leg is 0.08821 kgm²

Furkat [3]

Answer:

376.5 m

Explanation:

we know that

s=ut + 1/2 at^2

so here

u=49 m/s

t=5s

and a=g=9.8 m/s^2

so

s= 49×5 +1/2 ×9.8× 5×5

= 254+ 122.5

s= 376.5

What is the role of a commutator in an electric generator
Verdich [7]

Answer:

The role of a commutator in a electric generator is a rotary switch (in certain types of electrical generators that periodically reverse the current direction between the rotor and the external circuit by that reversing it in the current direction teb rotating windings all half turn a force called torque is produced)
