what are solar winds made of?
A. charged particles
B. nitrogen gas
C. oxygen gas
D. plasma
Answer:
Charged particles
Explanation:
It's correct
Answer:
Charged particles
Explanation:
The solar wind is a stream of energetic (charged) particles that the Sun ejects. These include hydrogen's electrons and protons, as well as atomic nuclei like helium, which are known as alpha particles. There are also evidence of 'heavy ions' and carbon, nitrogen, oxygen, neon, and magnesium atomic nuclei.
Bees can see into the ultraviolet region of the electromagnetic spectrum. Compared with humans, bees can sense electromagnetic waves that have a lower frequency and a shorter wavelength. a higher frequency and a longer wavelength. a lower frequency and a longer wavelength. a higher frequency and a shorter wavelength.
Answer:
a higher frequency and a shorter wavelength.
Explanation:
The correct answer would be a higher frequency and a shorter wavelength.
The visible region of the electromagnetic spectrum lies between 400 and 750 nm while the ultraviolet region lies between 300 and 400 nm. Hence, it means that bees are able to see at a shorter wavelength compared to humans.
There is an inverse relationship between the wavelength and frequency of a wave. the longer the wavelength of a wave, the shorter the frequency, and the shorter the wavelength, the higher the frequency. The means that bees are not just able to see at a shorter wavelength but at a higher frequency compared to humans.

A student wearing frictionless in-line skates on a horizontal surface is pushed by a friend with a constant force of 50.0 N.
How far must the student be pushed, starting from rest, so that her final kinetic energy is 350 J?
Pleaseeeee
Answer:
Distance = 7 meters.
Explanation:
Given the following data;
Force = 50N
Kinetic energy = 350J
To find the distance;
We know that energy possessed by an object over a distance represents the work done by the object.
Mathematically, work done is given by the formula;
Workdone = force * distance
350 = 50 * distance
Distance = 350/50
Distance = 7 meters.

4. A hockey puck with a momentum of -17 kg x m/s when it
collides with a hockey stick moving at 54 kg x m/s on ice.
Once the objects collide, the hockey puck has a momentum
of 35 kg x m/s, what must the momentum of the hockey
stick be?
Answer:
-2 kg x m/s
Explanation:
-17 + 54 = 35 + x
x = -2

How can you separate chalk from
chalky water?
Answer:
Yes
Explanation:
Because the call can evaporate from the water.
Answer:
A centrifuge is utilized to isolated little sums of strong held in suspension from the fluid. For case, chalk from water. The centrifuge contains test-tubes that are spun around at tall speed that causes the strong to sink to the foot of the tube. The fluid is the tapped (poured off) clearing out the strong behind.

A boy of mass 50 kg walks up a staircase of 10 steps each 15 cm high. Calculate the work done.
Answer:
735 J
Explanation:
Total height reached(displaced)=10x15 cm
= 10 x 15/100 m
= 1.5 m
Workdone = F.S (force x displacement)
Here, the boy is traveling against the gravitation force(=mg) , and traveled a height of 1.5m
Hence,
Workdone = 50 x 9.8 x 1.5 J
= 735 J
Answer:
750J
Explanation:
Solution;
M=50kg, g=10m/s
Distance=15×10÷100
=1.5m
W=M×g×h
=50×10×1.5
=750J
When developing a model of the cycling of water between the land, the ocean, and the atmosphere, one must include the forces that propel the water. For the model, these forces would be-
Answer: gl
Explanation:
When developing a model of the cycling of water between the land, the ocean, and the atmosphere. For the model, these forces would be gravity and sunlight( evaporation).
Sunlight causes evaporation and propels oceanic and atmospheric circulation, which transports water around the globe. Gravity causes precipitation to fall from clouds and water to flow downward on the land through watersheds. Energy from the sun and the force of gravity drive the continual cycling of water.
What is gravity ?"Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun."
What is energy ?"Energy is defined as the “ability to do work, which is the ability to exert a force causing displacement of an object.”
What is water cycle ?"The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow."

A4.0 μF capacitor is connected in series with a 2.0 MΩ resistor, and this combination is connected across an ideal 44.0 V DC battery. Initially the charge on the capacitor is zero. What is the current in the circuit when the capacitor has reached 80 % of its maximum voltage?
Answer:
i = 17.6 10⁻⁶ A
Explanation:
The charge of a capacitor in a series circuit is
i = [tex]\frac{v_o}{R}[/tex] [tex]e^{ - \frac{t}{RC} }[/tex] (1)
R i = V₀ e^{ - \frac{t}{RC} }
[tex]\frac{V}{V_o}[/tex] = e^{ - \frac{t}{RC} }
they tell us that the voltage is 80% bone
[tex]\frac{V}{V_o}[/tex] = 0.80
we substitute
0.80 = e^{ - \frac{t}{RC} }
ln 0.80 = [tex]- \frac{t}{RC}[/tex]
t = - RC ln 0.80
in the problem they give the value of R = 2.0 10⁶ Ω and C = 4.0 10⁻⁶ F
t = - 2 10⁶ 4 10⁻⁶ ln 0.8
t = 1,785 s
we substitute in equation 1
i = [tex]\frac{44.0}{2 \ 10^6}[/tex] [tex]e^{- \frac{1.785}{2 \ 4 } }[/tex]
i = 22 10⁻⁶ [tex]e^{-0.2231}[/tex]
i = 17.6 10⁻⁶ A

Complete Question:
Suppose [tex]A = B^n C^m[/tex], where A has the dimensions LT, B has dimensions L²T⁻¹, and C has dimensions LT². Then the exponents n and m have the values
Answer:
The value of n = ¹/₅
The value of m = ³/₅
Explanation:
Given dimensions;
A = LT
B = L²T⁻¹
C = LT²
The values of n and m are calculated as follows;
[tex]LT = [L^2T^{-1}]^n[LT^2]^m\\\\L^1T^1 = [L^{2n}T^{-n}]\times [L^mT^{2m}]\\\\L^1 \times T^1 = [L^{(2n+m)}] \times [T^{(-n +2m)}]\\\\1 = 2n + m -----(1)\\\\1 = -n + 2m ----(2)\\\\from \ (1); \ m = 1-2n, \ \ substitute \ the \ value \ of \ m \ in\ (2)\\\\1= -n +2(1-2n)\\\\1 = -n + 2-4n\\\\1-2 = -5n\\\\-1 = -5n\\\\1= 5n\\\\n = \frac{1}{5} \\\\m = 1 - 2n\\\\m = 1 - 2(\frac{1}{5} )\\\\m = 1- \frac{2}{5} \\\\m = \frac{3}{5}[/tex]
