Answer:
OPTION A is the correct answer
Answer:
The constriction causes the mercury column to break under tension, leaving a vacuum between the bottom of the column and that in the bulb, and the top of the column stays still at the position reached in the body - a "peak hold" system.
Answer:
85.66m
Explanation:
Given the following data;
Horizontal velocity = 25.8m/s
Height = 54m
Initial velocity = 0
We would first of all, solve for the time taken using the formula for maximum height of a projectile.
H = ½gt²
Where;
- H is the maximum height measured in meters.
- g represents the acceleration due to gravity measured in meters per seconds square.
- t represents the time taken measured in seconds.
We know that acceleration due to gravity is 9.8m/s²
Substituting into the equation
54 = ½*9.8t²
54 = 4.9t²
t² = 54/4.9
t² = 11.02
t = 3.32 secs
To find the distance;
Distance, x = velocity * time
x = vt
Substituting into the equation, we have;
x = 25.8*3.32
x = 85.66m
The statement “All of the earth's life and weather exists
within the stratosphere” is false. The answer is letter B. The answer is the
troposphere. The first layer, troposphere, is where we are able to do most of
our activities. This is where we can see the formation of clouds, the
production of rain, hail, snow and other weather phenomenon. Also, this layer
is where the greatest amount of air pressure because most of the molecules of
air are in this area. Like us, air has also mass and the pressure is brought
down by the earth’s gravity causing an increase in weight exerted on you as you
descend lower into the atmosphere. So, as you enter into the other layers of
atmosphere above the troposphere, the air pressure starts to decrease. <span>Below the
atmosphere is the hydrosphere. This is where all liquid forms are located. And
since the seawater has a greater mass than air, it has the greatest
pressure. </span>
Answer:
no..
Explanation:
in balanced force it will or in this case u would stay still or u would move at the same speed.. but when u jumps the speed changes..so this is an unbalanced force
