Sam constructs a circuit, connects a lead acid battery of 2 V to a lamp of resistance 3 Ω and places an ammeter across it. What must be the reading of the ammeter?

Answers

Answer 1

Answer:

0.67 Amps

Explanation:

As was pointed out in the comments, the fuse on this ammeter is likely to blow resulting in an error readout of 0.  To measure current, you measure in-line not across.  With that being said, let's assume that we are looking for the current of the circuit.  We can apply Ohm's law to find this value:

V = IR

V / R = I

I = V / R

I = 2V / 3Ω

I = 0.67 A

Assuming we had a very good ammeter and place it inline with the circuit, then we can say the reading will be 0.67A.

Cheers.

what is the hardware engineering​

Answers

Answer:

Hardware Engineering is the process of designing, developing, testing and producing computer systems and various physical components related to computer systems.

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.

Answers

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".

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.

Answers

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

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.

Answers

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

What is the mechanical advantage of a simple block and tackle with one rope?

Answers

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.

Explanation:

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

Actually this are some of the nitty gritty answers and ways to control or stip stress, lemme explain them you see stress most of the time may come from deep thoughts that are and are pushing you to the wall, and you in your state you as you react to that which is so demanding as it makes you tense,so if at you will incorporate physical activities like running, jogging or push ups the psychological tension in you is broken as you focus so much on the activities rather than the tension, then getting enough rest cools the mind and all your thoughts settle as in your brain starts to adapt to chilling and relaxation and enough sleep will actually make ones head to be at peace because if you lack enough sleep you might have an excruciating migraine when you are stressed up and finally relaxation techniques makes the body accept the situation and then you manouver out of it as you grow strongly.

Under the name of Isaac Merritt, he went to Rochester and became an actor. In 1839, during an absence from the theater, he completed his first invention, a mechanical excavator, which he sold for $2000.
