Some of the scientific questions that may be answered through the experiment are:

(1) What are the physical changes that may occur in the solution or the indicator when added with acidic/basic solution?

(2) How much of the indicator is needed in order to bring about a significant physical change in the solution to identify its H+ concentration?

If the gradient of an Extension versus Force graph was found to be 5.6, then what is the value of the spring constant? *
worty [1.4K]

Answer:

5.6

Explanation:

F=kx is the formula for spring force.  If Extension versus Force was graphed, a linear relation would appear, where the slope is the k value, aka the spring constant.

A bullet is accelerated down the barrel of a gun by hot gases produced in the combustion of gun powder. What is the average forc
Natali5045456 [20]

Answer:

<h2>9.3kN</h2>

Explanation:

Step one:

given data

mass of bullet= 0.02kg

speed v=700m/s

time taken =1.5ms= 0.0015 seconds

Step two:

we know that from the first law

F=ma-----1  first law of motion

also, we know that

a=v/t----2

put a=v/t in equation 1 we have

F=mv/t

Step three:

substitute our given data to find force

F=0.02*700/0.0015

F=14/0.0015

F=9333.33N

F=9.3kN

<u>The average force exerted is 9.3kN</u>
