What is the numerical value of the slope of the line (without units)? 0.083 24 8.3 12

What does it mean to say mass and weight are preportional to each other?

It means that if the mass of a mass is increased by some factor, and nothing else changes, then the weight of that mass increases by exactly the same factor.

The less mass an object has, the --- its gravitational f

BaLLatris [955]

Answer:

The less mass an object has, the less its gravitational [force.]

Explanation:

Newton's Law of Gravity states that $F_G=\frac{Gm_1m_2}{r^{2}}$ . The two m values are the objects' masses, G is the gravitational constant, and r is the distance between the objects' centers. Notice how the mass values are in the fraction's numerator? That means increasing the mass of one or both objects increases $F_G$ . That also implies the inverse; decreasing the mass of one or both objects decreases $F_G$ !

I hope this helps you understand this concept a little more! Have yourself a fantastic day, 'kay?

) Calculate current passing in an electrical circuit if you know that the voltage is 8 volts and the resistance is 10 ohms

Svetach [21]

Explanation:

Hey, there!

Here, In question given that, 

potential difference (V)= 8V

resistance (R)= 10 ohm

Now,

According to the Ohm's law,

V= R×I { where I = current}

or, I = V/R

or, I = 8/10

Therefore, current is 4/5 A or 0.8 A.

(A= ampere = unit of current).

Hope it helps...

A power plant generates 150 MW of electrical power. It uses a supply of 1000 MW from a geothermal source and rejects energy to t

marissa [1.9K]

Answer:

- the power to the air is 850 MW

- mass flow rate of the air is 84577.11 kg/s

Explanation:

Given the data in the question;

Net power generated; $W_{net$ = 150 MW

Heat input; $Q_k$ = 1000 MW

Power to air = ?

For closed cycles

Power to air Q₀ = Heat input; $Q_k$ - Net power generated; $W_{net$

we substitute

Power to air Q₀ = 1000 - 150

Q₀ = 850 MW

Therefore, the power to the air is 850 MW

given that ΔT = 10 °C

mass flow rate of air required will be;

⇒ Q₀ / CpΔT

we know that specific heat of air at p=c ; Cp = 1.005 kJ/kg.K

we substitute

⇒ ( 850 × 10³ ) / [ 1.005 × 10 ]

⇒ ( 850 × 10³ ) / 10.05

⇒ 84577.11 kg/s

Therefore, mass flow rate of the air is 84577.11 kg/s
