A 12 v automobile battery is connected to an electric starter motor. the current through the motor is 246

1 answer:

6 0

The power dissipated by the motor is given by:
$P=VI$
where V is the voltage of the battery and I is the current flowing in the circuit.

In our problem, the voltage is V=12 V and the current is I=246 A, so we can calculate the power dissipated by the motor using the previous equation:
$P=(12 V)(246 A)=2952 W$

Acrostic poem for cell theory. Especially theory

Sonja [21]

Answer:

In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.

Explanation:

The three tenets to the cell theory are as described below:

All living organisms are composed of one or more cells.

The cell is the basic unit of structure and organization in organisms.

Cells arise from pre-existing cells.

There is no universally accepted definition of life. Some biologists consider non-cellular entities such as viruses living organisms,[1] and thus reasonably disagree with the first tenet. Throughout this article, it will lead you through the history of cell theory, how the discovery of cells was made possible, what the cell theory has become today and background information and history regarding other opposing concepts of cell theory.

What are the applications of pascal's principle

Murrr4er [49]

Explanation:

The applications are, hydraulic lift- to transmit equal pressure throughout a fluid.
Hydraulic jack- used in the braking system of cars.
use of a straw- to suck fluids, which goes because of air pressure.

<h3>The question simply asks, where pressure can be applied. There are many others, such as lift pump.</h3>

A point on the string of a violin moves up and down in simple harmonic motion with an amplitude of 1.24 mm and frequency of 875

mario62 [17]

Using

V = Amplitude x angular frequency(omega)

But omega= 2πf

= 2πx875

=5498.5rad/s

So v= 1.25mm x 5498.5

= 6.82m/s

B. .Acceleration is omega² x radius= 104ms²

What are advantages and disadvantages of using a solar cooker compared to other meanings of cookings?

drek231 [11]

The advantage of using a solar cooker is that it is Eco-friendly and the disadvantage is that it can be used only under certain conditions.

ADVANTAGES

Using it is friendly to the environment
It can be easily assembled without expert assistance
No compromise on the quality and taste of foo

DISADVANTAGES

Requires sun to function and prepare food
Cannot function in winters or monsoon when the sun isn't present
Does not retain heat as efficiently and quickly as compared to other cooking appliances
