Answers
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?
Answers
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

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.
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
Answers
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.

A boy of mass 50 kg walks up a staircase of 10 steps each 15 cm high. Calculate the work done.
Answers
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

An object accelerates at 32 m/s² when a force of 71 N is applied to it. What is the object’s mass?
Answers
Answer:
2.21875 kg
Explanation:
FORCE = MASS x ACCELERATION so to find mass we divide both sides by acceleration. M=F/A
SO 71N/32m/s²=2.21875 kg.
remember N=kgm/s² so m/s² is canceled by m/s² the remaining is kg
The answer is mass= 2.21 kg
The first step is to write out the parameters given in the question
acceleration= 32 m/s²
force-= 71 N
The formula for calculating the object's mass is
mass= force/acceleration
= 71/32
= 2.21 kg
Hence the object's mass is 2.21 kg

C. a beaker of water and a ruler
D. a ruler and a meter stick
Answers
Answer:
A balance and a beaker of water!
Explanation:
Krishne wants to measure the mass and volume of a key. The tools that are to be used are – a balance and a beaker of water.
Mass will be represent with the amount of matter that is in an object. This will be measured in terms of kilogram. The mass can easily be measured with balance.
Volume is the quantity of matter that is in the object. This is measured in terms of cubic meter. If you drop the key in a beaker of water, the water inside the beaker will increase and this increases the volume of water that will be equal to volume of key.

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.
