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)
Both physicians Einstein and Newton explained the gravity.
Einstein described the gravity by suggesting that the space-time around any object is bent, while Newton described gravity by principle of action.,
This is true
A fan is a complex machine because it consists from 2 simple machines and includes various forces used such as the torque and the thrust.
Answer:
2.7 J
Explanation:
From the question,
The Net work done by the crate = Work done by the crate in moving if through a distance- work done against friction.
W = Fd-F'd.................... Equation 1
Where F = force applied to the crate, d = distance moved by the crate, F' = force of friction
Given: F = 2.4 N, F' = 0.6 N, d = 1.5 m
Substitute these values into equation 1
W = 2.4(1.5)-0.6(1.5)
W = 3.6-0.9
W = 2.7 J
