The statement "Since monsoons are storms that usually occur during a specific time of year in certain regions, you could not compare them to thunderstorms" is absolutely false.
What is monsoon?Monsoon may be characterized as a seasonal transformation in the direction of the predominant, most potent, currents of a region. It blows from cold to warmer regions of the geographical locations.
Thunderstorms basically originated identically with monsoons more frequently. Monsoon involves sudden and gradual rainfall, extreme wind, and a drop-down in temperature.
The occurrence of monsoon is fixed at different geographical locations, but the occurrence of thunderstorms will not be definite or predominantly known.
Thus, the statement "Since monsoons are storms that usually occur during a specific time of year in certain regions, you could not compare them to thunderstorms" is absolutely false.

VR is always greater than MA. why?
Answer:
The mechanical advantage (M.A) of a real machine is always less than its velocity ratio(V.R) because mechanical advantage decreases due to the friction and weight of moving parts of the machine whereas the velocity ratio remains constant.
A car initially traveling at 15.0 m/s accelerates at a constant rate of 4.50 m/s2 over a distance of 45.0 m. How long does it take the car to cover this distance? Show all work leading to the answer including the data, equation, substitution and the final answer with units for full credit.
Answer:
2.24 seconds
Explanation:
xf = xo + vo t + 1/2 at^2
45 = 0 + 15 t + 1/2 (4.5) t^2
2.25 t^2 + 15t - 45 = 0 Quadratic formula shows t = 2.24 seconds
The car takes approximately 2.25 seconds to cover a distance of 45.0 meters under the given conditions of constant acceleration.
Given data:
Initial velocity (u) = 15.0 m/s
Acceleration (a) = 4.50 m/s²
Distance (s) = 45.0 m
We can use the kinematic equation to solve for time (t) when the car covers a certain distance under constant acceleration:
S = ut + 1/2at²
Where:
s = distance
u = initial velocity
a = acceleration
t = time
Plugging in the given values:
45.0 = 15.0t + 1/2 m/s²t²
2.25t² +15t - 45 = 0
t = 2.25sec and -8.92sec
Since time cannot be negative in this context, we discard the negative solution.

What is the main difference between a longitudinal wave and a transverse wave? a longitudinal wave always travels faster than a transverse wave. a longitudinal wave does not need a medium to travel through. a transverse wave is made of particles that move perpendicular to the motion of the wave. a transverse wave always carries more energy so that it can travel through empty space.
In a longitudinal wave, the propagation of energy is in the direction of the motion, while in a transverse wave the propagation of energy is perpendicular to the direction of motion.
What is longitudinal wave and Transverse wave?Longitudinal wave is a wave which moves in the direction from where it was started. It has a compression (increased intensity) of the medium particles and a rarefaction ( reduced intensity).
Transverse wave is wave that travels perpendicular or at right angles to the direction from where it was started.
The main differences between longitudinal wave and Transverse wave are:
Transverse wave, the medium moves vertically up and down while in the longitudinal wave, the medium moves left to right.Transverse wave has a crest and a trough while the longitudinal waves have a compression and rarefaction.Transverse waves don't have a pressure variation , longitudinal waves have a pressure variation.Transverse waves can only be propagated in solids and on the surfaces of liquids, Longitudinal waves can be propagated in solids, liquids and gases.Transverse waves don't change in density throughout the medium, longitudinal waves have a change in density throughout the medium.Therefore,

HELP PLEASE!!! In the diagram, q1 = -6.39*10^-9 C and q2 = +3.22*10^-9 C. What is the electric field at point P? Include a + or - sign to indicate the direction. 91 92 P 0.150 m ** 0.250 m (Hint: The distance from q1 to P is NOT 0.150 m.) (Remember, E points away from + charges, and toward charges.) (Unit = N/C) HELP PLEASE!!
Answer:
E = K Q / R^2
E1 = K Q1 / R1^2 = K * (-6.39 E-9) / .4^2 = -K 39.9 E-9
E2 = K Q2 / R2^2 = K * 3.22 E-9 / .25^2 = K 51.5 E-9
Field will point to right of P since E2 (positive) stronger
E = K (E2 - E1) = 9.0 E9 * (51.5 - 39.9) E-9 = 104 N/C
The electric field at point P is 104.6 N/C.
What is meant by electric field ?Every place in space where a charge exists in any form has an electric attribute that can be defined as the electric field.
Here,
q₁ = -6.39 x 10⁻⁹C
q₂ = 3.22 x 10⁻⁹C
Distance from q₁ to P, d₁ = 0.4 m
Distance from q₂ to P, d₂ = 0.25 m
Electric field at P due to q₁, E₁ = k x -6.39 x 10⁻⁹/(0.4)²
E₁ = -39.9 x 10⁻⁹k N/C
Electric field at P due to q₂, E₂ = k x 3.22 x 10⁻⁹/(0.25)²
E₂ =51.52 x 10⁻⁹k N/C
Therefore, total electric field at P,
E = E₂ - E₁
E = (51.52 - 39.9) x 10⁻⁹k
E = 104.6 N/C
Hence,
The electric field at point P is 104.6 N/C.
