Choose the answer choice that BEST completes the following sentence. About four million tons of __________________ are converted
yaroslaw [1]

Answer:

<em>About four million tons of </em><em><u>matter</u></em><em> are converted to energy in the Sun’s core every second</em>

Explanation:

<u>The Sun </u>

It's estimated that The Sun fuses near 600 million tons (6.10^9\ kg) of hydrogen into helium every second. As a result, 4 million tons of matter are converted to energy every second according to Einstein's equation E=mc^2

Can someone please help!!
frosja888 [35]

Answer:

Weight needed to balance the bar is 8.5N

Explanation:

Given the weight of the bar is 8N

The length of the bar is 5m

The weight of the bar will be uniformly distributed over the entire span. We will consider this as a point load acting in the middle of span length, which is at a distance of 2.5m from both ends.

Now applying momentum equation about balanced load we get, (see attachment)

\sum m_i=0\\2(m)+8(1)-8(0.5)-7(3)=0\\2m+8-4-21=0\\2m-17=0\\2m=17\\m=\frac{17}{2}=8.5\\So,\ m=8.5N

Alekssandra [29.7K]

Answer:Deforestation refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities. Greatly accelerated by human activities since 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate. The UN’s Food and Agriculture Organization estimates the annual rate of deforestation to be around 1.3 million km2 per decade.

Two particles are attracted to each other by the gravitational force between them. Particle 1 has a mass of 12kg, Particle 2 has
svlad2 [7]

Answer: 1.4 x 10^-8N

Explanation:

Given that,

Mass of Particle 1 (m1) = 12kg

Mass of Particle 2 (m2) = 25kg

distance between particles (r) = 1.2m. Gravitational force (F) =

Apply the formula for gravitational force:

F = Gm1m2/r²

where G is the gravitational constant with a value of 6.7 x 10^-11 Nm2/kg2

Then, F = (6.7 x 10^-11 Nm²/kg² x 12kg x 25kg) / (1.2m)²

F = (2.01 x 10^-8Nm²) / (1.44m²)

F = 1.396 x 10^-8N (Rounded to the nearest tenth as 1.4 x 10^-8N)

Thus, the magnitude of the gravitational force acting on the particles is 1.4 x 10^-8 Newton
