A particular type of resistor has a tolerance of 3%. Technician A says this indicates that the resistor’s current value can be 3
1 answer:
Answer:
Technician B is correct.
Explanation:
The given value of resistor having 3% tolerance means that the given quantity of the physical parameter can vary by 3% of what is specified. This variation can be either more or less than the quantified value.
- When the variation can occur on both sides of the stated value then it is called bilateral tolerance, usually represented as,
.
- When the variation is permissible only in one direction then it is called unilateral tolerance, represented by the sign + for the impressibility on the higher side and
sign for the impressibility on the lower side.

It is given that, the water from a fire hose follows a path described by equation :
........(1)
The x component of constant velocity,
We need to find the resultant velocity at the point (2,3).
Let and
Differentiating equation (1) wrt t as,
When x = 2 and
So,
Resultant velocity,
v = 6.4 m/s
So, the resultant velocity at point (2,3) is 6.4 m/s. Hence, this is the required solution.
Explanation:
It is given that,
The distance between the radio and the radio station is 174 m
We need to find how many wavelengths of the radio waves are there between the transmitter and radio receiver if the woman is listening to an AM radio station broadcasting at 1540 kHz.
f = 1540 kHz
Wavelength,
Let there are n wavelengths of the radio waves. So,
There are 0.89 wavelengths.
