Which of these is the most likely impact of solar prominence on Earth? A) rerouting of aircraft
B) increase in severity of hurricanes
C) long-term electrical power generation
D) improvement in satellite communication

Answers

Answer 1
Answer:

Solar prominences themselves are of no concern because they are visible in the Hydrogen Alpha wavelength. They are anchored in place by magnetic fields. When these fields break or reconnect, it can send the plasma that makes up the prominence away from the sun. If one of these clouds impacts Earth, they are called CMEs or coronal mass ejections. Depending on the magnetic orientation of the cloud with respect to Earth's the CME can break down our magnetic field resulting in geomagnetic storms, aurorae, power grid fluctuations, and particle radiation near the poles, satellite single upset events, and radio blackouts. 


Thus, letter a is the answer.

How does the direction of the change in velocity compared to the direction of the acceleration?

Answers


Technically, you can simply point out that "acceleration" MEANS
"change in velocity", so of course they have the SAME direction.
Actually, because acceleration is the derivative of velocity (or change of velocity at a certain point), the acceleration can be in a different direction than the velocity. If the velocity's magnitude is increasing away from zero, then the acceleration is in the same direction as velocity. If the velocity is getting closer and closer to zero (either from the negative or positive end of the number line) then the acceleration is in the opposite direction of velocity.
Think of it like a car. When you are slowing down to stop at a light, your velocity is still going forwards, but your acceleration is negative because it is decreasing the velocity. A negative acceleration is another way of saying that the acceleration is going in the opposite direction of the frame of reference.
If the car is speeding up, the velocity is forward, and the acceleration is in the same direction because the change of velocity is positive.
Hope this helped! :D

What is the law of inertia?

Answers

Inertia: Objects tend to move at the same speed and direction or, if at rest, stay at rest. A force has to be applied to overcome inertia. An objects inertia is determined by the mass of the object.

Answer:

The law of inertia is mostly known the same as THE NEWTONS FIRST LAW OF MOTION which states that"A body will continue to its state of rest or motion unless acted by an external forces"

●WHAT IS INERTIA?

Inertia is the ability of a body at rest to resist motion or a body in motion to resist resting unless acted by external forces.

△TYPES OF INERTIA

■There are 3 types of inertia,

◎Inertia of rest

◎Inertia of direction

◎Inertia of motion

What are geothermal heat pumps used for?a. Cooling and heating buildings
b. Cooling buildings
c. Heating buildings
d. Heating water for using in homes

Answers

Heat pumps are also known as refrigeration units for heating and cooling homes by taking heat from air outside in the winter time and then reversed to take heat out of the inside of a home in the summertime. The Geothermal heat pumps take heat from the ground by way of buried pipes deep in ground with chemicals such as water and glycol or similar and transfers that heat into homes in the winter time.
Heating buildings

Is a battery that generates hydrogen,is that very explosive

Answers

The answer is yes!
Hydrogen gas is generated as part of the charging process of lead/acid cell batteries. If the hydrogen gas acculates in large concentrations in a building or room or a box, an electrical spark or other ignition source will cause the hydrogen to burn in a rapid reaction causing an possible explosion.
A good example of a hydrogen gas explosion and fire is the "Hindenburg" disaster of the old flying blimps or zepplins.

Thermal energy is added to a sample, its particles move ?

Answers

Yes, if the temperature increases, than that means the particles are moving faster. Temperature is the measure of movement of particles in an object or substance.

By thermal energy, you mean adding heat correct....? I'm not very good at this sort of thing, but I gave you what I have..
