The comments below about tornadoes are untrue; they do not typically occur near the warm front associated with a midlatitude cyclone.
Which of these three tornado kinds are they?There are several different kinds of tornadoes, such as multiple vortex tornadoes, landspouts, and waterspouts. Waterspouts as characterized by a wind current that spirals into the shape of a funnel and connects to a sizable cumulus of cumulonimbus cloud.
what is The causes of tornadoes?Warm, humid air rises inside thunderclouds while chilly air descends, bringing with it rain or hail and rain. Air currents within the cloud may spin as a result of these circumstances. Despite their initial horizontal orientation, the whirling currents have the ability to change vertical, drop from the cloud, and eventually form a tornado.

A 75 kg man falls off his ladder and hangs motionless from the ceiling by a cord. Determine the net force on the man. (don't forget units)
PLEASE HELPP
The net force on the 75 kg man who falls off his ladder and hangs motionless from the ceiling by a cord is zero.
What is the weight of a body?The weight of a body is the force of gravity acting on the body. The weight of a body acts downward.
Mathematically, the weight of a body is given below as follows:
Weight = m * g
where;
m is the mass of the object
g is the acceleration due to gravity = 10 m/s²
The weight or the force of gravity acting downwards on a 75 kg man that falls off his ladder and hangs motionless from the ceiling by a cord is calculated as follows:
The force of gravity = 75 * 10
The force of gravity = 750 N
The tension on the cord balances the weight of the man and acts in the opposite direction.
Hence, the tension on the cord is equal to 750 N but in the opposite direction.
Net force = weight - tension
Net force = 750 N - 750 N
Net force = 0 N

The drawings show three examples of the force with which someone pushes against a vertical wall. In each case the magnitude of the pushing force is the same. Rank the normal forces that the wall applies to the pusher in ascending order (smallest first).1st drawing is a medium angle2nd drawing is a small angle3rd drawing is a large angle (almost 90 degrees and perpendicular to the wall)
The normal forces that the wall applies to the pusher in ascending order are :Normal force in the third drawing (large angle),Normal force in the first drawing (medium angle),Normal force in the second drawing (small angle).
The normal force is the force that an object exerts on another object that is in contact with it. In the case of a person pushing against a wall, the normal force is the force that the wall applies to the person.
The magnitude of the normal force is determined by the angle at which the person is pushing against the wall. For a given magnitude of the pushing force, the normal force will be smaller when the angle is larger and larger when the angle is smaller.
In the first drawing, the angle is medium, so the normal force will be between the normal force in the second and third drawings.
In the second drawing, the angle is small, so the normal force will be larger than the normal force in the first drawing and smaller than the normal force in the third drawing.
In the third drawing, the angle is large, so the normal force will be the smallest of the three.

s it possible to change velocity while moving at a constant speed?absolutely not because they are of the same value; a speed is just a magnitude of a velocity.yes, if acceleration has component parallel to the velocity but has no component perpendicular to the velocity.yes, if acceleration has component perpendicular to the velocity but has no component parallel to the velocity.no, change is velocity will be always followed by the change in speed.
Yes, provided that the acceleration contains components that are parallel to and inversely proportional to the velocity.
Explaining an accelerationAcceleration describes the speed and direction changes in velocity over time. Acceleration refers to the change in speed or direction of an item or point traveling straight forward. Due to the frequent changes in direction, motion on a circle accelerates even while the speed stays the same.
What are the 3 different forms of acceleration?The three different categories of accelerated movements are uniform acceleration, non-uniform acceleration, and average acceleration. When an object moves in a straight path while experiencing equal-interval increases in velocity, this motion is referred to as having uniform acceleration.

a plane files from point a to point b. b is 1207 km west 957 km south a. sketch a picture of this situation. what is the total displacement of the plane
The closest distance and angle to this question are 1540.35 kilometers and 38.4 ° S. (depending on how you rounded).
What is Displacement and distance are they equivalent?There is a common misconception that distance & displacement are simply two different terms for the same thing. But separation separates the concepts of distance and displacement. The total distance covered by an object is always larger than the movement between those two sites, even if it changes direction throughout the course of its voyage.
The displacement is which one, which?The smallest (straight line) length between a body's starting position and its final location—represented by an arrow pointing from starting spot to final position—is referred to as a brain's displacement when it moves through one position to another.
