If you go to the right along the periodic table, electronegativity increases.
So the larger the column number, the greater the electronegativity.
-Lithium has lowest as it is in the 1st column
-Beryllium (2nd column)
-Boron s (13th column)
-Nitrogen (15th column)
The jet streams are narrow bands of fast moving air. They travel from the west coast towards the east coast over the United States, and so an aircraft flying from New York to Los Angeles would be flying into the jet stream rather than with it. This would cause the following:
- The flight would use more fuel, as the aircraft must push its way against the force of the jet stream
- The flight would also take longer, as thrust is needed to push against the jet stream as well as to push the aircraft forwards.
Answer:
The the speed of the car is 26.91 m/s.
Explanation:
Given that,
distance d = 88 m
Kinetic friction = 0.42
We need to calculate the the speed of the car
Using the work-energy principle
work done = change in kinetic energy
Put the value into the formula
Hence, The the speed of the car is 26.91 m/s.
Answer:
Yes.
Explanation:
Yes Light has inertia, since inertia is in units of mass.
Answer:
Standard weight: We calculate the standard weight as follows: G = L * mweight, where L is the length of the beam calculated as the difference between the extreme points of the beam body along the direction of the beam axis, taking into account all features except holes.
