I think an object such as an iron pipe could work
Answer:

Explanation:
As we know that when runner is moving on straight track then the net force on his feet is given as

while when runner is moving on circular track then we have




now percentage change is given as



Answer:They act on different bodies
Explanation:
Newton's third law of motion states that for every action there is equal and opposite reaction i.e. action and reaction. Though action and reaction are equal they act in different bodies that is why they do not cancel out each other.
For example, a block of mass m placed over the table exerts a force of mg to the table while the table applies a Normal reaction of equal magnitude as of mg to the block of mass m.

Actually Welcome to the concept of distance formula.
Distance formula ==>

so applying this we get as,
D = underoot (9)^2 + (-5)^2
==> D = 10.29 units
distance = 10.29 units
In a science lab, there is the adequate availability of raw materials for experiments such as chemicals while outside a science lab there isn't.
In a science lab, the availability of apparatuses and sources of heat is higher than outside a science lab.
<h3>What is science laboratory?</h3>
The science lab is a place where the experiments related to the science background are performed with the use of apparatus.
The science lab has plenty of equipment to perform the experiment whether related to physics or chemistry or biology.
Thus, source of heat and availability of raw material and equipment are the differences between the science activities carried out in a science laboratory and those carried out side of science laboratory.
