Solar flares produce lethal levels of radiation. What type of warning will astronauts receive before these high-energy particles are hurled at them?
Answer:
Even inside their ships, astronauts are exposed to a slow drizzle of cosmic rays coming right through the hull. The particles penetrate flesh, damaging tissue at the microscopic level. One possible side-effect is broken DNA, which can, over the course of time, cause cancer, cataracts and other maladies.
Two resistors r1=100 ohm and r2=220 ohm are connected in series across a voltage of 6.4v calculate the resistance of the resistor equivalent to r1 and r2
Answer:
r_eq = 320 Ω
Explanation:
It is asked to find the equivalent resistance of a series circuit formed by two resistors r₁ and r₂
r_eq = r₁ + r₂
r_eq = 100 + 220
r_eq = 320 Ω
with this value we can find the current that circulates through the circuit
V = r_eq i
i = V / r_eq
i = 6.4 / 320
i = 0.02 A
How is mechanical weathering affected by climate
Explanation:
In general, hot wet climates accelerate chemical weathering while cold dry climates accelerate physical weathering. Although the rate of weathering depends on the type of rock, rocks in tropical climates experience the highest rates of weathering because of the combination of high heat and heavy rainfall.

Which is the wavelength of a wave that travels at a speed of 3.0 × 10^8 m/s and has a frequency of 1.5 × 10^16 Hz?
Answer:
2 x 10^-8
Explanation:
the formula of wavelength is
the speed divided by frequency
so you have the speed given = 3.0x10^8m/s
and frequency = 1.5×10^16 Hz
so wavelength = 3.0x10^8m/s / 1.5x10^16 Hz

a force 4000 n accelerates a car of mass 800 kg from rest to 20 ms how far does the car travel while the force is acting?
Answer:
d = 40 m
Explanation:
Given that,
Force, F = 4000 N
Mass of a car, m = 800 kg
Initial velocity, u = 0 (at rest)
Final velocity, v = 20 m/s
We need to find the distance traveled. Force acting on a car is given by :
F = ma
Where
a is the acceleration of the car.
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{4000}{800}\\\\a=5\ m/s^2[/tex]
Let it has traveled d distance. Using third equation of motion.
[tex]v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{(20)^2-(0)^2}{2\times 5}\\\\d=40\ m[/tex]
So, the required distance is equal to 40 m.

explain how the weight of a body changes as the body is taken farther away from the surface of the earth
The weight of a body is dependent on the gravitational force of its location.
WEIGHT:Weight is a force measured in Newton. It is often used interchangeably with mass, however, they are very different.
Weight refers to the mass of an object or body in relation to gravity. This means that gravity determines the weight of an object.
Weight changes as the gravitational force changes. This means that if a body is taken farther away from the surface of the earth, the weight changes because the gravitational force determines weight.

What is the difference between obtaining knowledge from a controlled experiment versus other forms of scientific investigation?
Answer:
Any scientific investigation in its simplest form involves collecting information, while a controlled experiment is a tightly controlled investigation that tests a hypothesis.
Explanation:
All the scientific investigations start with a particular question. The question decides what type of investigation should research take. A controlled experiment is an investigation which allows a particular variable to change and all other variable controlled to remain constant to see the effect on dependent variable to test a particular hypothesis while other types of investigations are used to increase the knowledge or information about the particular research subject.
What happens when you throw a basketball up toward the hoop? If you are lucky, the ball sinks into the net. You score two points before the ball drops down to the ground. The basketball isn’t heavy. Why doesn’t it stay up in the air when you throw it? Have you ever heard the saying, What goes up must come down? This saying helps explain what happens to the basketball. It is being acted on by an invisible force called gravity. Gravity is the force in the universe that attracts all objects to each other.
Gravity has existed since the beginning of the universe. It holds everything in the universe in place. We know it is always there. It is hard to understand how it works. First, you need to understand that there is gravitational attraction between all objects. There is gravitational attraction between you and Earth, between Earth and the Moon, and between Earth and the Sun. You cant feel the gravitational attraction between you and Earth. However, it is what keeps your feet planted firmly on the ground. Imagine spinning around and around on a merry-go-round. As long as you hold on, you will stay on the merry-go-round. Don’t let go! You will fly off and land on the ground. This analogy helps us visualize the gravitational attraction between Earth and you. Earth is spinning on its axis. Gravity keeps you on Earth rather than flying out into space.
Now think about the gravitational attraction between Earth and the Moon. The same force that keeps you on Earth pulls the Moon and Earth together. This attraction keeps the Moon in orbit around Earth. Also think about the affect of the Moons gravitational force on Earths oceans. The gravitational pull of the Moon makes the ocean tides rise and fall.
There is attraction between you and Earth and between the Moon and Earth. The Sun also has a gravitational pull on Earth. This attraction makes the Earth orbit the Sun. The Suns attraction is very strong. All objects in the solar system orbit around this medium-sized star. What would happen if the Suns gravitational attraction suddenly disappeared? All the planets, including Earth, would fly off into space just like you would if you let go of the merry-go-round.
There is gravitational attraction between all objects. Why is the effect stronger in some cases? For example, Earths gravity has a more powerful effect on you than the Suns gravity. How could this be possible? After all, the Suns gravitational attraction holds all of the objects in the solar system. The force of gravity between two objects actually depends on two things. It depends on the mass of the two objects. It also depends on the distances between them. The greater the mass of the objects, the greater the gravitational force between them. In other words, the bigger an object is, the more gravity it has. Distance also has a large effect. The closer objects are to each other, the stronger their gravitational force of attraction. As they get farther apart, the force between them gets weaker. The Sun is much more massive than Earth, but the distance between you and Earth is less. The gravitational pull of the Sun has little effect on you because the distance is so large.
Gravity is the invisible force that attracts all objects, no matter their size or mass. The Sun has the strongest gravitational force of any object in the solar system. It attracts all astronomical objects into orbit around itself. Without this force, everything would fly off into the universe.

I believe gravity is the most important aspect of our universe. Without it we would all be floating off into the universe. There wouldn’t be any orbits; instead, all planetary bodies would simply float around, running into each other when they crossed paths and just wandering forever.
There is a gravitational force between all objects in the universe. Gravitational force is what keeps all components of our solar system in orbit around the Sun, as well as moons in orbit around planets. The force of gravity affects Earth's tides and holds us on Earth's surface. The force of gravity between objects depends on their masses and the distance between them.
Gravity is hard to understand and scientists have little to no understanding of how it works. We know that gravity is out there, but the specifics are often lost on us. Plants, animals, and humans are all able to grow tall due to the pull on Earth from the Sun. Without the Sun we would all just stretch out along Earth's surface.

the magnetic flux density of a given conductor is 3.6T. Given that the conductor generates 12.9N and has a length of 10cm, calculate the current being carried
Answer:
i = 5.28 A
Explanation:
The magnetic force is given by the expression
F = i l x B
the bold letters indicate vectors, let's write the modulus of that expression, where the direction between the conductor and the magnetic field is 90º, therefore the sine 90 = 1
F = i l B
i = F / l B
let's reduce the length to the SI system
l = 10 cm (1m / 100 cm) = 0.10 m
let's calculate
i = 12.9 / 0.1 3.6
i = 5.28 A
