Answer:
A block and tackle is characterized by the use of a single continuous rope to transmit a tension force around one or more pulleys to lift or move a load. Its mechanical advantage is the number of parts of the rope that act on the load. The mechanical advantage of a tackle dictates how much easier it is to haul or lift the load.

Hope this helps- have a good day ^w
A block and tackle is a lifting or moving technique that uses a single continuous rope to deliver tension force around one or more pulleys.
What is block and tackle?A system of two or more pulleys with a rope or cable threaded between them, known as a block and tackle or merely tackle, is typically used to raise heavy weights.
The pulleys are put together to form blocks, and the blocks are then coupled such that one moves with the weight and the other is fixed.
Thus, A block and tackle is a lifting or moving technique that uses a single continuous rope

Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application.
Answer:
Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. ... The term engineering is derived from the Latin ingenium, meaning "cleverness" and ingeniare, meaning "to contrive, devise".

100.0 mL of 4.0°C water is heated until its temperature is 37°C. If the specific heat of water is 4.18 J/g°C, calculate the amount of heat energy needed to cause this rise in temperature.
Answer:
13794 J
Explanation:
The formula to apply here is that equation for heat energy ;
q= m*Cp*ΔT
where ;
q= heat variable
m= mass of water = 100 g
Cp = specific heat of water = 4.18 J/g °C
ΔT = 37-4 = 33 °C
Substitute values in the equation as;
q= 100 * 4.18* 33 = 13794 J

Which statement most accurately describes the continuity equation?
A.
The volume of water flowing through a section of a pipe varies inversely with its pressure.
B.
The volume of water flowing through a section of a pipe varies directly with the speed of water flow.
C.
The volume of water flowing through a section of a pipe varies inversely with the speed of water flow.
D.
The area of a pipe’s cross section varies inversely with the speed of water flow.
E.
The area of a pipe’s cross section varies directly with the speed of water flow.
Answer:
The correct option is;
The area of a pipe's cross section varies inversely with the speed of water flow
Explanation:
A continuity equation is an equation that shows the behavior of a quantity as it moves or is transported from one point or state to another
Therefore, the continuity equation is highly effective when the quantity being considered is conserved and from which bases generalization of the principle of the motion of the quantity can be generalized
Therefore, for the relationship between a pipe's cross section and the speed of water flow, we have;
A ∝ 1/v
Therefore, we have A₁·v₁ = A₂·v₂, which is a continuity equation.
Answer:
The answer is D.
Explanation:
The continuity equation states that the speed of water flow varies inversely with the area of a pipe’s cross section; that is, if the pipe narrows, the speed of water flow increases, and vice-versa. From Plato's tutorial
