Response:

Overall distance is 20 km, with a displacement of 0 km

His displacement is reported as 0 km since he finishes his journey at the starting point. The total distance covered was 20 km — this comprises 10 km to the store plus the 10 km return to his home.

According to the second law, heat, often called thermal energy, cannot be entirely turned into work.
The second statement is closely tied to this law.
We can conclude that some energy dissipates while some is used for work.

You're driving your pickup truck around a curve that has a radius of 22 m.How fast can you drive around this curve before a stee
Sav [3041]

The maximum speed around this curve before a toolbox made of steel slips off the truck bed is: 14.832 m/s

Further explanation

The centripetal force acts on objects in circular motion, directed towards the circle's center.

\large {\boxed {\bold {F = \frac {mv ^ 2} {R}}}

F = centripetal force, N

m = mass, Kg

v = linear velocity, m / s

r = radius, m

The velocity directed toward the center of the circle is referred to as linear velocity.

It can be represented as:

\displaysyle v = 2 \pi.r.f

r = radius of the circle

f = rotations per second (RPS)

Pickup trucks negotiating a curve are influenced by centripetal forces. To prevent the steel toolbox from slipping off the bed of the truck, the centripetal force acting on it must equal its weight. Should the centripetal force surpass the toolbox's weight, it will fall off.

centripetal force = weight

\rm \dfrac{mv^2}{r}=mg

Thus, the maximum velocity to keep the toolbox secure is:

\rm v^2=r\times g\\\\v=\sqrt{r\times g}

For a curve with a radius of 22 m, it follows that:

\rm v=\sqrt{22\times 10}\\\\v=\sqrt{220}\\\\v=\boxed{\bold{14.832\:m/s}}}

Sav [3041]

Answer:160j

Explanation:

PE=mgh

where m=8kg

g=10N/kg

h=2m

Thus, PE=8*10*2

This results in PE=160j
