The air pressure ( or atmospheric pressure ) is the force of air over a unit of area. Changes in the air pressure causes the weather changes. High pressure usually brings good weather with dry and cool air. But in a low pressure zone warm air is rising up. This vertical movements are caused by winds high in the troposphere. Water molecules stay as a gas in warmer air. After the vertical movement they condense and bring steady continuous rain. Therefore the low pressure brings cloudly and rainy weather. Answer: The air pressure is most likely low<span>. </span>
Answer:
u need to make sure that comparison is = to shapes and then find the shapes sizes and add them
Answer:
a) 15.49
b) Opposite to the ball's initial velocity
c) 258.16N
Explanation:
a)

b)
Since the player is kicking the ball in the opposite direction to which it came, the impulse is being directed opposite to the ball's initial velocity.
c)

Hope this helps!
Answer:
Force = 150 Newton.
Explanation:
Given the following data;
Mass = 60kg
Acceleration = 2.5m/s²
To find the force;
Force = mass * acceleration
Force = 60 * 2.5
Force = 150 Newton.
Therefore, the force required to accelerate this mass is 150 Newton.
Answer:
k = 138440 N/m
Explanation:
given,
Mass of the car = 1200 Kg
speed of the car = 85 km/h
= 85 x 0.278 = 23.63 m/s
KE of the car

Using Spring Energy Formula

Using conservation of energy



k = 138440 N/m
Spring stiffness constant of the spring is equal to k = 138440 N/m
