What is a truck's acceleration if the net external force on the truck is 560 N and it has a total of mass of 1000 kg?
Allisa [31]

Answer:

0.56m/s²

Explanation:

The above is the correct answer.

Force = mass x acceleration = mg

⇒ F = mg

where F = 560 N, m = 1000kg

∴ g = F/m = 560/1000 = 0.56

∴ acceleration, g = 0.56m/s² (answer)

Force is known to be a push or a pull which actually puts a body to motion or brings a body to rest.  It has to do with the interaction between bodies.

In general, how does biodiversity vary across the biosphere?
Tamiku [17]
Life needs energy, water, heat and nutrients. Reduce the availability of one or more of those things and biodiversity generally decreases.

Tropical forests tend to be more diverse than polar ice caps. However, arctic seas tend to be more biologically interesting than the middle of the Sahara. I bet this is what your homework is looking for but it's important to remember there are counterexamples.
