Answer:
d. to anticipate heat changes
Explanation:
Magnus installs the switch with a bimetal element, so that when the current in the circuit increases above the nominal value, the temperature in the conductor will likewise increase, the bimetal element has the ability to deform when significant temperature changes. In this way it anticipates dangerous current values deforming before and protecting the circuit.
Answer:
W = 14523.6 J
Explanation:
Given,
Mass = 3.9 Kg
Vertical height , h = 380 m
Work done against gravitational force
W = m g h
g is acceleration due to gravity
W = 3.9 x 9.8 x 380
W = 14523.6 J
Hence, the work done by the gravitational force is equal to W = 14523.6 J
Answer: The focal length would be four inches

Answer and explanation:
The efficiency of the LED bulb is 20% while The efficiency of the Inc bulb is 1%.
The lightbulb efficiency can be defined as the quotient between the amount of usable light and the amount of electrical power output. For the efficiency of the CFL Bulb:
Therefore:
Answer:
Displacement =
Magnitude of displacement = 13.89 units
Angle of displacement = 30.26°
Explanation:
Mark the co-ordinates of each of the end points of the vectors.
The marked co-ordinates are shown below.
Displacement is the shortest distance between two points. Here, displacement between the starting and end points is the vector .
Displacement vector for a point A from origin O is given as:
Magnitude is given as:
Direction of the vector is given as:
Therefore, displacement vector is:
Magnitude of displacement is given as:
Angle of displacement is:
°
