I would say the answer is D
A hygrometer is an instrument used to measure relative humidity. ... To determine the relative humidity, the temperatures are taken from the dry-bulb thermometer and the temperature difference between the wet and dry bulb thermometers.
hygrometer is a weather instrument used to measure the amount of humidity in the atmosphere. There are two main types of hygrometers -- a dry and wet bulb psychrometer and a mechanical hygrometer.
A. 314 because when you use the formula for the GPE ; GPE=MGH or means mass times gravity time height (4x8x9.8) and thats equivalent to 313.6 which rounds up to 314. Hope it helps
Answer:
The tension T in each of the cables, T = 98 N
Explanation:
Given,
The mass of the loudspeaker, m = 20.0 Kg
The suspended distance of the loudspeaker, d = 2.20 m
The length of each cable, l = 2.9 m
The tension experienced by the cable is given by the formula,
T = mg + ma newton
Where,
g - acceleration due to gravity
a-acceleration produced by the stretched cable
Since the stretched cable and loudspeaker is not moving, then the tension force acting on the cable is equal to the force of gravity.
T = mg newton
Substituting the values in the above equation
T = 20
= 20.0 Kg x 9.8 m/s²
= 196 N
This force is equally supported by the two cables, then the tension in each cable is
T = 196 N / 2
= 98 N
Hence, the tension T in each of the cables, T = 98 N
Answer:
If the experiment works and the data is analyzed you can either prove or disprove your hypothesis.
