Answer:
The term “cold-blooded” implies that these animals are in a never-ending struggle to stay warm. That really isn't correct. A cold-blooded animal can warm up their blood by being in the sun for hours.
Answer:
Zero
Explanation:
Work done is given by multiplying force and distance moved. The distance is moved both positive and negative and it's equal distance. Since force used is the same hence work
W=F*d+ (F*-d)=0
Therefore, total work done is zero
The pressure exerted on the block on the ground in N/m² is 200N/m².
<h3>What is pressure?</h3>
The pressure is the amount of force applied per unit area.
Given is a 5000 Newton block rests on the ground over 25 m² of area.
Pressure p = Force/Area
Put the values, we get
p = 5000 /25
p = 200 N/m²
Hence, pressure exerted on the block on the ground is 200 N/m².
