Answer:
The united states is considered to have a high standard of living because brainly.
Explanation:
Cc s ? All I know is that 1+1= 2
Answer: Twice the previous time would be taken to reach the same speed v with the puck of mass 2m.
Explanation:
Let a Force pushes the hockey puck of mass m.
Then acceleration, a= \frac{F}{m}a=mF
From the equation of motion,
\begin{gathered}\➪ v=u+at\\ v=0+\frac{F}{m}\Delta t\end{gathered}⇒v=u+atv=0+mFΔt ......(1)
In the second case, when mass is 2m, then acceleration,
a'=\frac{F}{2m}a′=2mF
and t' is the time taken.
The final speed is v,
\begin{gathered}\➪ v=0+ a't'\\ \➪ \frac {F}{m}\Delta t=\frac{F}{2m}t'\\ \➪ t'= 2\Delta t\end{gathered}⇒v=0+a′t′⇒mFΔt=2mFt′⇒t′=2Δt using equation (1)
Hence, it would take two times the previous amount of time to push the pluck of double mass.

The difference in muscularity between the crop and the gizzard earthworm is that; Crop muscularity is soft while for gizzard it is hard.
<h3>What are the differences in Muscularity?</h3>
Earthworms usually eats the soil that has organic matter such as leaves and others.
Now, the digestive system of earthworms is made up of pharynx, oesophagus, intestine, gizzard and crop. The mode of digestion is that the food passes through the esophagus after which it is now pushed down the crop where it is used for storage and then in the gizzard where the food is being grind.
Finally. the difference between the crop and the gizzard is that the crop muscularity is soft while that of gizzard is hard.
