In three to four sentences, explain how climate change could impact the formation of hurricanes. (4 points)
daser333 [38]

The climate change can directly impact the formation of hurricanes because increasing temperature increases intensity of hurricanes.

<h3>How climate change could impact the formation of hurricanes?</h3>

Evaporation increases as temperatures rise which also causes the transfer of heat from the oceans to the atmosphere. As the storms travel across oceans whose water is warm, they absorb more water vapor and heat which increases rainfall as well as intensity of hurricanes.

So we can conclude that the climate change impacted the formation of hurricanes due to increasing temperature that increases intensity of hurricanes.

Why do atoms have an overall neutral charge?
Y_Kistochka [10]
Atoms have an overall charge that is neutral because atoms have equal number of positive protons and negative electrons thus they cancel each other out. This always true for atoms that are stable and in equilibrium.

A raindrop falls to the ground from a raincloud at an altitude of 3000 meters.
Dmitrij [34]

Answer:

24.7 s

Explanation:

Question is appear to be missing. Found it on google:

"a) If there were no air resistance, how long would it take to fall?"

Solution:

We can solve the problem by using the following equation of motion for a uniform accelerated motion:

d=ut+\frac{1}{2}at^2

where

d = -3000 m is the displacement of the raindrop (negative because in the downward direction)

u = 0 is the initial velocity of the raindrop if we assume it starts from rest

t is the time taken for the fall

a = g = -9.8 m/s^2 is the acceleration of gravity

Solving the equation for t, we find:

t=\sqrt{\frac{2d}{g}}=\sqrt{\frac{2(-3000)}{-9.8}}=24.7 s

A 50.0 mg sample of an unknown radioactive substance was placed in storage and its mass measured periodically. After 19.7 days,
PilotLPTM [1.2K]
<h2>Answer: 4.928 days </h2><h2 />

Explanation:

This problem can be solved using the <u>Radioactive Half Life Formula: </u>

<u></u>

A=A_{o}.2^{\frac{-t}{h}} (1)

Where:

A=3.13mg is the final amount of the material

A_{o}=50mg is the initial amount of the material

t=19.7days is the time elapsed

h is the half life of the material (the quantity we are asked to find)

Knowing this, let's substitute the values and find h from (1):

3.13mg=(50mg)2^{\frac{-19.7days}{h}} (2)

\frac{3.13mg}{50mg}=2^{\frac{-19.7days}{h}} (3)

Applying natural logarithm in both sides:

ln(\frac{3.13mg}{50mg})=ln(2^{\frac{-19.7days}{h}}) (4)

-2.77=-\frac{19.7days}{h}ln(2) (5)

Clearing h:

h=\frac{-19.7days}{-2.77}(0.693) (6)

Finally:

h=4.928days

What are the similarities and differences between an electric bell and a circuit breaker​
alexgriva [62]

Answer:

differences and similarities

Explanation:

An electric bell is a mechanical or electronic bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing, clanging or ringing sound. whereas,

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.
