Answer:
Explanation:
Given data:
v = 220 rms
power factor = 0.65
P = 1250 W
New power factor is 0.9 lag
we knwo that
s = 1923.09 < 49.65^o
s = [1250 + 1461 j] vA
solving for
Faraday
Answer:
Speed of the car around the circular path will be 12 m/sec
Explanation:
We have given mass of the car m = 1500 kg
Radius of the curve r = 45 m
Centripetal acceleration of the car
We have to find the speed of the car
We know that centripetal acceleration is given by , here v is car speed along the circular path and r is radius of the curve
So
v = 12 m/sec
So speed of the car around the circular path will be 12 m/sec
Answer: The engine size
Explanation:
Explanatory variable is a type of independent variable, but it may not always be independent. It is varied to determine its effect on the response variable. In this case, to establish a relationship between gas mileage of cars and the engine size, one will want to predict the average gas mileage for various engine size. Therefore, the engine size is the explanatory variable while the gas mileage is the response variable.
Explanation:
Objects like apples, wood, and sponges are less dense than water. They will float. Many hollow things like empty bottles, balls, and balloons will also float. That's because air is less dense than water.
