Answer:

$we \: know \: energy \: = \: force \: \times distance \\ e = f \times d \\ so \: f \: = \frac{e}{d} \\ so \: th \: force \: here \: = (\frac{2670}{3}) newton \\ = 890newton$

Hope it helps

How are the layers of the earth connected and affected by each other

Usimov [2.4K]

Answer:

This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases We have the inner core, outer core, mantle and crust which play an important role on Earth.

Mechanics: design a decision tree to determine if an object is experiencing an unbalanced force, and using newton's laws of moti

masya89 [10]

Answer:

The decision designer is a step-wise process

Explanation:

A typical decision tree will be like this:

Are there any forces?

YES - then calculate the resultant forces NO - Then no calculations are needed

IF YES - Are the forces balanced? NO - Then no calculations

IF YES - Then calculations can be done.

Resolve the forces to find the resultant of the forces in the question.

The open-circuit voltage of a car battery is measured to be 12 V. During engine startup, the battery delivers 10 A to the starte

dmitriy555 [2]

Answer:

- the Thevenin equivalent circuit for the battery is uploaded below

- the battery delivered 117 watts of power to the starter motor

Explanation:

Given the data in the equation

diagram of the Thevenin equivalent circuit for the battery is uploaded below.

Current I = 10 A

Voltage 1 = 12 V

voltage 2 = 11.7 v

R = (V1 - V2) / I

R = (12-11.7)/10

R = 0.3 / 10

R = 0.03Ω

Thevenin equivalent circuit

$R_{L}$ = V2 / I = 11.7 / 10

$R_{L}$ = 1.17Ω

so, power delivered to the starter motor will be;

p = (V2)² / $R_{L}$

P = ( 11.7 V )² / 1.17Ω

p = 136.89 / 1.17

p = 117 watts

Therefore, the battery delivered 117 watts of power to the starter motor
