Answer:

The correct answer is option , are renewable resources

Explanation:

Biofuels can be produced every year through the commercial crops. These crops after processing produces raw organic waste which can be used as manure or it can be put into some other sustainable use. Unlike fossil fuels which take millions of year to form, biofuels are easily convertible. Biomass fuels are grown on the earth crust and thus are product of living things

The moon revolves around earth at a fairly constant speed.Is the moon accelerating

inysia [295]

If the moon changes direction, it's because it is orbiting around the earth, and the moon keeps a constant speed. And when the moon turns, it accelerates due to velocity. So yes, the moon accelerates.

An unstretched spring has a length of 10. centimeters. When the spring is stretched by a force of 16 newtons, its length is incr

Fed [463]

Answer:

The spring constant of this spring is 200 N/m.

Explanation:

Given:

Original unstretched length of the spring (x₀) = 10 cm =0.10 m [1 cm =0.01 m]

Stretched length of the spring (x₁) = 18 cm = 0.18 cm

Force acting on the spring (F) = 16 N

Spring constant of the spring (k) = ?

First let us find the change in length of the spring or the elongation caused in the spring due to the applied force.

So, Change in length = Final length - Initial length

$\Delta x = x_1-x_0=0.18-0.10=0.08\ m$

Now, restoring force acting on the spring is directly related to its elongation or compression as:

$F=k\Delta x$

Rewriting in terms of 'k', we get:

$k=\dfrac{F}{\Delta x}$

Now, plug in the given values and solve for 'k'. This gives,

$k=\frac{16\ N}{0.08\ m}\\\\k=200\ N/m$

Therefore, the spring constant of this spring is 200 N/m.
