Answer:
See the answer below
Explanation:
a. The volume in the first measuring cylinder reads 70 
while that of the second reads 95 . Hence;
V1 = 70
V2 = 95
b. <u>An object will always displace its own volume in a liquid</u>. Hence:
Volume V of the rock sample = V2 - V1
= 95 - 70 = 25
c. Mass of A = 102 g
Volume of A = 25
<em>Density = mass/volume</em>
Hence, density of A = 102/25 = 4.08 g/
If she is moving in a straight line at a constant speed,
then her acceleration is zero.

Hint: Here, we can see that 12 and 13 are consecutive numbers. So, all numbers between squares of 12 and 13 are non-square numbers. Therefore, first find squares of 12 and 13 and then subtract square of 12 from square of 13, we get numbers of non-square numbers. At the last subtract 1 from the result obtained as both extremes numbers are not included.
Complete step-by-step answer:
In these types of questions, a simple concept of numbers should be known that is between squares of two consecutive numbers all numbers are non-square numbers. Also one tricky point should remember that whenever we find the difference between two numbers we get a number of numbers between them including anyone of the extreme numbers. So we subtract 1 to exclude both extreme numbers.
Square of 12 = 122=144 and square of 12 = 132=169
As 12 and 13 are consecutive numbers so all numbers between their squares will be non-square numbers.
Therefore, 169 – 144 = 25
Total number of numbers between 169 and 144 (i.e., excluding 144 and 169) = 25 – 1 = 24.

If you multiply m (the unit for wavelength) with 1s (the unit for frequency), you will get m/s, the unit for speed. Now multiply! 25 m/s is your final answer!
