Answer:
B. 59 kg
Explanation:
From the graph you notice that a linear relation in indicated by the line joining the points such that the points on the line represent the data that show a correct relationship in the experiment.
This means that the point outside the line has an error .
This point is the value 59 kg that does not align with other values which are included in the graph.
The answer is Providing national parks
Answer:
c. A, C
Explanation:
On equi-potential surface, fields are equal in magnitude at all points . If field is zero at all points , they will be equal so first option is correct.
Field is perpendicular to equipotential surface at all points.
The required equation for the sine function can be written as; V = 120sin120πt
<h3>What is a sine function?</h3>
A sine function is a regular repeating function. We know that the voltage is represented using a sine function of the general form V= V-o sin2πft
Hence;
f = 60 cycles per second
V-o = 120 volts
So from the values that we have stated above;
V = 120sin120πt
