A 0.40 kg object is attached to a spring with force constant 157 N/m so that the object is allowed to move on a horizontal frict

nirvana33 [79]

Answer:

Part a)

$F = 26.7 N$

Part b)

$a = 66.7 m/s^2$

Explanation:

Part a)

Force on the object due to spring force is given as

$F = kx$

here we know that

$k = 157 N/m$

$x = 0.17 m$

so we have

$F = 157\times 0.17$

$F = 26.7 N$

Part b)

Acceleration of the object is given as

$a = \frac{F}{m}$

$a = \frac{26.7}{0.40}$

$a = 66.7 m/s^2$

What is the effect of decreasing the use of fossil fuel on animals threatened by extinction?

Eduardwww [97]

Answer:

Decreasing the use of fossil fuels will improve the wellbeing of animals (and people, for that matter). Burning fossil fuels like coal and using oil and other limited resources has polluted the biosphere, and this has had an adverse impact on many animals. If we were to limit this, it would no doubt improve their situation and make them less likely to extinction.
