<h2>
Height of bridge is 83.66 m</h2>
Explanation:
We have equation of motion s = ut + 0.5 at²
Initial velocity, u = 25.3 m/s
Acceleration, a = 9.81 m/s²
Time, t = 2.29 s
Substituting
s = ut + 0.5 at²
s = 25.3 x 2.29 + 0.5 x 9.81 x 2.29²
s = 83.66 m
Height of bridge is 83.66 m
The correct answer to this question is this one:
By definition, if a molecule is composed of two hydrogen atoms and one oxygen atom, that molecule is a water.<span> In fact, the structure of water is written as H20, which signifies that two hydrogen (H) atoms and one oxygen (O) atom make up the molecule.</span>
<u>T</u><u>he area w</u><u>h</u><u>ich touches the sand floor of 4 feet of the bull is less than the man.</u>
because the area of surface of contact is more in bull than in man. More is the area of contact, leads is the force or pressure affected.
Answer:
18. Direction.
19. Speed.
20. Speed.
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;

Because the velocity of an object depends on direction as well as speed, the velocity of an object can change even as the speed of the object remains constant. Thus, the velocity would change only when the direction or speed of the object changes.
