Available options are:

A. –4500 N

B. –2500 N

C. 2500 N

D. 4500 N

Answer:

-4500 N

Explanation:

Given that we have F₁ = 3000N? (force of the barge)

the force of the tugboat is F '

To pull the barge, the force of the tugboat must be greater than or equal to the force of the barge.

Hence, according to Newton's third law which states that for every action or force in nature, there is an opposite reaction.

Therefore considering the available option the correct answer is "- 4500N, " this is because it is greater than the force of the barge and it's in opposition to the force exerted.

Hi! Some rocks are porous material, like a sponge, with lots of air pockets inside, so they can absorbe water. In this case, the water level dropped 5.65m because tha volume of water went inside the rock filling the air pockets. The water replaced the air, that flowed to the outside water as bubbles and then to the air above the water.

How do you calculate kWh, watts and joules?

likoan [24]

Answer:

Joules=F*d, watts= J/s, Kwh= kw*h(time)

Explanation:

First, we need to know... what are we measuring with the different units:

Joules: This unit is used to measure energy and work.

$EnerKinec=\frac{1}{2} * m[kg]*v^{2} [m^{2}/s^{2} ]\\\\Enpot=m[kg]*g[m/s^{2}]*h[m]\\ \\Work=F[N]*d[m]$

Watts: This unit is used to measure power, and is related to energy and work when we use the time. That is, power equals work or energy per unit of time.

$Power = \frac{work[J]}{time[s]} = [watts]$

KWh: This unit is used to measure the amount of power consumed, it is very common to see it on electric energy bills.

$Powerconsumed=Power*hoursworked\\\\Powerconsumed= power[kw]*hoursworked[hr]=[Kw-h]$
