Answer
The steps in order to explain how a tornado forms are;
1. An extreme difference in wind speed at two elevations causes the wind shear
2. The difference in wind speed causes a column of air to rotate horizontally
3. A strong updraft connects the rotating air with clouds above
4. The column of air stretches to form a tornado
Explanation
The typical steps of tornado formation follow the below steps;
• Occurrence of a large thunderstorm which happens in the cumulonimbus clouds
• There is a change in wind direction and speed at higher attitudes that makes the air to swirl horizontally
• Air rising from the ground pushes up on the swirling air and tips over it
• The swirling air funnel starts to suck up more warm air from the ground
• The funnel enlarges and stretches towards the ground
• The funnel touches the ground level to form a tornado
a) many people think that no energy or matter exists outside the universe.
An isolated system is defined as a system that does not interact with its surroundings. This is the reason that its total energy and mass remains constant. Moreover, t<span>otal</span><span> momentum in a system is conserved for collisions occurring in </span><span>isolated systems.</span>
Answer:
+ 3.0 m
Explanation:
displacement is shortest distance from fixed point O in particular direction . in diagram shortest distance at end from O is 3 m and it is right of O so +. HENCE +3.0m
Answer:
a) y = 16.51 [m]
b) t = 1.83 [s]
Explanation:
To solve this problem we must use two kinematics equations, the first to determine the height to which the ball reaches, and the second equation to determine how long it lasts in the air.
where:
Vf = final velocity = 0
Vi = initial velocity = 18 [m/s]
g = gravity acceleration = 9.81[m/s^2]
t = time [s]
Note: the negative sign of the Equation indicates that the acceleration of gravity acts in the opposite direction to the movement of the ball. The final velocity is zero, since the ball reaches its maximum altitude when the velocity is zero.
Now replacing:
0 = (18)^2 - (2*9.81*y)
y = 16.51 [m]
b)
0 = 18 - (9.81*t)
t = 1.83 [s]
The answer would be c. hope this helps☺
