Explanation:
1. Location.
Hurricanes are defined as severe tropical storms that form over warm ocean waters starting as storms in the Caribbean(North American continent) or off the west coast of Africa. As the storms drift slowly westward, they gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power.
Warm, moist air moves toward the center of the storm and spirals upward. Hurricanes rotate in a counter-clockwise direction around an “eye.”
2.
It is low lying. Majority of their lands are just a few feet above sea level.
3. Most of the infrastructures are built on rocks that are permeable to water. Hence, water bubble or seep out in unexpected places. Building of sea walls and other barriers to prevent rising seas, storms etc.
The correct answer to the question is : 9375 N.
CALCULATION:
As per the question, the mass of the car m = 1500 Kg.
The diametre of the circular track D = 200 m.
Hence, the radius of the circular path R =
=
= 100 m.
The velocity of the truck v = 25 m/s.
When a body moves in a circular path, the body needs a centripetal force which helps the body stick to the orbit. It acts along the radius and towards the centre.
Hence, the force acting on the car is centripetal force.
The magnitude of the centripetal force is calculated as -
Force F =
=
= 9375 N. [ANS}
The centripetal force is provided to the car in two ways. It is the friction which provides the necessary centripetal force. Sometimes friction is not sufficient. At that time, the road is banked to some extent which provides the necessary centripetal force.
The magnitude of the net force on the car is 9375 N, directed towards the center of the track. The net force is caused by the combination of the car's weight and the normal force of the road. These forces provide the necessary centripetal force to keep the car in its circular path.
The magnitude of the net force on the car can be calculated using the formula F = m×a, where m is the mass of the car and a is its acceleration. Since the car is moving in a circular path, its acceleration can be determined using the formula a = v^2/r, where v is the velocity of the car and r is the radius of the circular track. The direction of the net force is towards the center of the circular track, as it provides the necessary centripetal force to keep the car moving in a circular path.
Using the given values, the magnitude of the net force on the car is F = (1500 kg) × (25 m/s)^2 / (100 m) = 9375 N. The direction of the net force is towards the center of the circular track since it provides the centripetal force required to keep the car in its circular path.
The net force on the car is caused by two external forces: the weight of the car and the normal force of the road. The weight of the car acts vertically downwards, while the normal force of the road acts perpendicular to the surface. These two forces combine to provide the net force that keeps the car moving in a circular path.

Explanation:
Answer::l=V/f
= 331/680= 0.48m
Explanation: if that isnt an option, round up to 0.5, thats what i had to do
c. vertically along the direction that the wave travels.
d. perpendicular to the path of travel.
As a longitudinal wave travels through a medium, it displaces the particles parallel to the direction which the wave travels.
This type of waves are vibrations that takes place in the same direction i.e parallel to the wave motion. They are usually mechanical and examples include sound waves which requires a medium.
A longitudinal wave is a form of wave in which the displacement of the medium and the medium's vibration are both parallel to the direction of the wave.
A longitudinal wave moves the particles parallel to its direction of passage as it passes through a material.

Answer:
A- Parallel to tge direction which the wave travels
Explanation:
Wave A will be faster than the wave B because
The frequency of the wave is defined as the cycle completed by the wave per second.
Now it is given in the question:
Frequency of wave A = 250 hertz
The wavelength of wave A= 30 cm
Frequency of wave B = 260 hertz
The wavelength of wave B= 25 cm
Now for finding which wave is faster we will calculate the velocity of the wave.
For Wave A
For wave B
We can see that the velocity of wave A is higher than the velocity of wave B.
Thus wave A will be faster than the wave B because
