1.0 joule= 1.0 newtons × 1.0 meter = 1.0 newton × meter
Work = 10 newtons × 5 meters = 50 newton × meter
If the length and linear density are constant, the frequency is directly proportional to the square root of the tension.
Answer:
The height of the bridge is 14.5
Explanation:
Given the following data
t = 2.9 seconds
g = +10m/s^2
Using the below formula
H = ut + 1/2gt^2
Since the initial velocity u = 0
Then, H = 1/2gt^2
H = 1/2 x 2.9 x 10
H = 2.9 x 10 / 2
H = 2.9 x 5
H = 14.5
frictional force that air exerts against a moving object
Answer:
Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions
