Explanation:
Well, generally when a Hooke's Law experiment is performed the plot is in fact Force vs Displacement, being the Force (in units of Newtons) in the Y-axis and the Displacement (in units of meters) in the X-axis.
In addition, if we add a linear fit the resultant equation will be the Line equation of the form:
Where is the slope and
is the point where the line intersects the Y-axis.
So, if the equation is:
The slope of this line is which is also the spring constant
.
Answer:
Rate of change of magnetic field is
Explanation:
We have given diameter of the circular loop is 13 cm = 0.13 m
So radius of the circular loop
Length of the circular loop
Wire is made up of diameter of 2.6 mm
So radius
Cross sectional area of wire
Resistivity of wire
Resistance of wire
Current is given i = 11 A
So emf
Emf induced in the coil is
Answer:
The answer is "36 grams".
Explanation:
In this question, the weight of the ball is not mentioned but is the weight of the cookies is declared, which is equal to 36 grams, and all the cookies are squeezes into the ball and after that, it calculates the overall weight so, let assume that ball weight is =0 and then the overall weight is:
