The force over the inclined plane required to elevate the barrow is less than the straight surface as there was the tangential gravitational force acting on the barrow.
What is force?The force is the push or pulls experienced by the object when interacting with the other object. The force applied is calculated with respect to the force experienced by the object.
On moving the wheelbarrow over a straight surface, the gravitational force acting over it requires more force to elevate it in the opposite spatial relation.
Over the inclined plane, the wheelbarrow experiences the tangent of the gravitational force over it, and less force is required to elevate the barrow to the same level as the straight surface.

Explanation:
We know that Newtow Third's Law is F=ma, so we can solve for the tension on the side with that and the acceleration given in the y.
After that depending on which section of girder you chose there is a shear force and a normal force as well as a moment on the inside of it, meaning the middle of it, since is uniformly distributed, breaking down on the left the shear force is usually up, and the normal to the right, the moment counterclockwise, so from then is just a matter of doing the sumation of forces on the y and x and the summation of the moments, just remember to account for now being half of the total mass, we still have acceleration on the y, so the summation of moments will equal summation of kinetic moments, where we take into account every force that is trying to make it move, in this case, half the mass of the grinder and the acceleration going up, hope it helps you.

Technician A states that the wider the gap on an A/C clutch, the greater the electrical resistance measurement is observed when checking the windings. Technician B states that a wide clutch gap causes the compressor to remain engaged. Who is correct
Technician B is correct because it's true that a wide clutch gap in an A/C clutch would cause the compressor to remain engaged.
What is an A/C clutch?An A/C clutch can be defined as a mechanical device that is designed and developed for the conversion of energy generated by the engine and delivers it to the compressor.
For instance, when an air conditioner (A/C) is turned on, the clutch becomes engaged and it begins to spin rapidly and constantly, so as to transfer power to the air conditioner (A/C).
In conclusion, technician B is correct while technician A is wrong because it's true that a wide clutch gap in an A/C clutch would cause the compressor to remain engaged.

Explanation:
Using the Breguet range and endurance equation, estimate the amount of kerosene
fuel needed for an aircraft weighing 10 metric tons (this is the dry weight that
includes passengers and cargo) to fly from Boston to Los Angeles, assuming a
distance of 5,000 [km], flying at 300 [m/s].
Assume a lift-to-drag ratio of 15 - this is the ratio of lift force over drag force during
the cruise, the overall efficiency of 0.3, and about half of the standard air density at
an altitude of approximately 6,000 [m]. You can neglect the climb and descent
phases of the flight. The energy density of kerosene is provided in Module 9, section
3: "The Breguet range and endurance equation". Why is this a tricky calculation?
The amount of kerosene fuel needed for an aircraft weighing 10 metric tons to fly from Boston to Los Angeles, assuming a distance of 5,000 [km] is 10000 kg.
What is Breguet equation?Breguet equation is used to determine the range of airplane fly in some specified set of parameters.
[tex]R=\dfrac{h_f}{g}\dfrac{L}{D}\times \eta \ln \left(\dfrac{W_{initial}}{W_{final}}\right)[/tex]
Here, (L/D) is lift to drag ratio, g is gravitation acceleration, h is height and W is weight.
The weight of aircraft is 10 metric tons (this is the dry weight that includes passengers and cargo) The distance of 5,000 [km], with velocity at 300 [m/s] from Boston to Los Angeles has to be cover by the airplane.
The initial weight is 10 metric tons or 10000 kg. Thus, the final weight with total fuel burn is,
[tex]W_{final}=W_{initial}-W_{fuel}\\W_{final}=1-\dfrac{W_{fule}}{W_{initial}}[/tex]
The lift-to-drag ratio is 15 and the overall efficiency is 0.3, The standard air density at an altitude of approximately 6,000 [m] is half.
Thus, put the values, in above formula,
[tex]5000=\dfrac{6000}{9.81}(15)\times(0.3) \ln \left(\dfrac{10000}{1-\dfrac{W_{fuel}}{10000}}}\right)\\[/tex]
[tex]\ln \left(\dfrac{10000}{1-\dfrac{W_{fuel}}{10000}}}\right)=1.8167\\\ln \left(\dfrac{1}{10000-W_{fuel}}}\right)=1.8167[/tex]
Solving this equation, we get,
[tex]W_{fuel}=10000\rm\; kg\\[/tex]
Thus, the amount of kerosene fuel needed for an aircraft weighing 10 metric tons to fly from Boston to Los Angeles, assuming a distance of 5,000 [km] is 10000 kg.

Answer:
This article deals with weight formula and its derivation. Weight refers to the force which acts on a body or object due to the effect of gravity. So, when an individual stands on a scale, the reading that appears is the weight. The more an individual weighs consequently means a higher reading on the scale. When an individual loses weight, he should think of it as lessening one’s force on the Earth due to gravity.
weight formula
What is Weight?
Simply speaking, weight refers to the force of gravity. Weight is certainly a force that acts on all bodies or objects at all times near a heavenly body such as the Earth. The Earth pulls all objects downward towards the center with a force of gravity. One can find the magnitude of the force of gravity by multiplying the magnitude of the acceleration due to gravity by the mass of the particular object.
Some books describe weight as a scalar quantity, the magnitude of the gravitational force. In contrast, some books refer to weight as a vector quantity, the gravitational force which acts on the object. Moreover, some experts explain weight as referring to the magnitude of the reaction force which is exerted on a body by various mechanisms. Also, these mechanisms keep the body in place.
The unit of measurement for weight is certainly that of force. This unit in the International System of Unit (SI) is the newton. The object with a mass of 1 kilogram would weigh about 9.8 Newtons on the Earth’s surface. Furthermore, it would weigh about one-sixth as much on the moon.
Weight Formula
The weight of an object or body certainly depends on the mass of the object and the gravity acting on it. This is why, the weight is different from mass. The mass of an object would be same whether on the Earth or on the Moon. The weight of an object due to the influence of gravity would be different on the Earth than on the Moon. The weight formula can be explained as follows:
Weight = mass × gravity
The formula for this is:
w = mg
Here we have,
w = weight
m = mass
g = gravity
