Further explanation

Torque (moment of force) with respect to the pivot suggest P is characterized as the product that the size of the force F and also the moment"s arm

τ = l . F

The torque can be clockwise or counterclockwise (counterclockwise significant +, clockwise significant -)

For objects with 2 or much more forces, the total torque is:

Στ = τ1 + τ2 + ... τn

From images attached

τ = -rm x F

rm = (arm pressure which is perpendicular to the work line)

⇒ an adverse sign due to the fact that the torque is clockwise to the point P

while the size of the arm pressure rm:

rm = r sin θ

How much old plant debris is necessary to kind one foot of coal?
jen2175forals.comsd209 <6>
It is stated that ten feet of old plant debris was essential in bespeak to do one foot of coal. This is true since fossil fuel were formed from plants and animals that live 300 million years earlier in primordial swamps and also oceans. Eventually, numerous of the seas receded and left dried land with fossil fuels favor the one you are talking about, coal

Identify the locations on the image where the force of repulsion is the least.
ArbitrLikvidat <17>

Each magnet has a north pole and a southern pole. We recognize that, from having played v bar magnets in ours childhood, that a magnet"s phibìc pole will certainly repel one more magnet"s north pole and also attract its south pole.

From this diagram it is easy to see that the two lower bar magnets not just repel every other, however they are rather attracted to each other since their north and south poles space close together.

Therefore the an ar between the lower two magnets has the least pressure of repulsion.

In a circus performance, a monkey ~ above a sleds is provided an initial speed of 4.3 m/s increase a 24◦ incline. The an unified mass of the monk
Serggg <28>


d = 1.15 m


In lack of friction, the change in kinetic power of the an unified mass that the monkey and also the sled, must be same (with the opposite sign), come the change in gravitational potential energy:

ΔK = -ΔU

When friction is no negligible, the readjust in mechanical energy, should be equal to the job-related done by non-conservative forces (kinetic friction in this case):

ΔK + ΔU = Wnc (1)

As the monkey + sled reach to the maximum distance up the incline, they will come momentarily come a stop, for this reason the last kinetic power is 0.


The adjust in gravitational energy, deserve to be created as follows:


The sum of these 2 quantities, must be equal to the work done by the friction force, follow me the distance d up the incline:


The regular force, always normal come the surface, must be equal and also opposite come the component of the weight regular to the incline:


Replacing in the equation for Wnc:


We have the right to return to the equation (1) and also solve because that d:

2.11 m


From the question provided above, the complying with data to be obtained:

Mass (m) = 4.76 Kg

Initial velocity (u) = 0 m/s

Final velocity (v) = 6.5 m/s

Height (h) =?

NOTE: Acceleration as result of gravity (g) = 10 m/s²

The elevation of the refrigerator can be derived as follow:

v² = u² + 2gh

6.5² = 0² + (2 × 10 × h)

42.25 = 0 + 20h

42.25 = 20h

Divide both next by 20

h = 42.25 / 20

h = 2.11 m

Therefore, the frozen fridge is 2.11 m high
