Explanation:
There are some easy ways to conserve water to help protect our aquifers, watersheds, and ground water. First, we can all conserve water, by not running the water while we brush our teeth and making sure we fix all leaking or dripping faucets. Another was to conserve water is to collect rain water to use to water your plants. Speaking of plants, you can also plant more zeroscape type landscapes that require less water. We can also update our shower heads and toilets to be low-flow and more efficient. Can't afford a new toilet? Simply add a brick to your tank and this will cut down on the water used for every flush.
The flow chart shows the life cycle of a star. Was this star smaller than our sun, about the same or bigger than our sun?
1. Bigger
2. About the same
3. Smaller
The star is bigger than our sun. The correct option is 1.
The flow chart of the life cycle of a star indicates that the star starts as a nebula, which is a cloud of gas and dust. The nebula can collapse due to gravitational forces and form a protostar. The protostar can then continue to contract and heat up until it reaches a temperature and density at which nuclear fusion can occur, leading to the star entering the main sequence phase.
The size of a star is determined by its mass, and the more massive a star is, the bigger it will be. Based on this information, we can infer that if a star follows the life cycle shown in the flow chart, starting from a nebula and eventually reaching the main sequence, it must be at least as massive as our sun or even more massive, since only stars with sufficient mass can become main sequence stars.

Answer:
A is the correct answer 0.158
158 Milligrams of salt are on the table there would be 0.158 grams of salt on the table, therefore the correct answer is option A.
What is a unit of measurement?A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.
As given in the problem 158 Milligrams of salt are on the table, then we have to find out how many grams of salt is on the table,
1000 milligrams = 1 gram
1 milligram = 1 / 1000 grams
158 milligram = 158 × 1 / 1000 grams
=0.158 grams
Thus, there would be 0.158 grams of salt on the table, the correct answer is option A.

what is the pressure exerted, what is the pressure exerted by 50kg girl as she places her weight on one shoe if the heels area is 0.002m²
Answer:
The pressure exerted by the girl is 245,000 N/m²
Explanation:
Given;
mass of the girl, m = 50 kg
area of the girl's shoe, A = 0.002 m²
The pressure exerted by the girl is calculated as follows;
[tex]P = \frac{F}{A} \\\\Where;\\F \ is \ the \ force \ exerted \ by \ girl's \ weight\\\\P = \frac{F}{A} = \frac{mg}{A} = \frac{50 \times 9.8}{0.002} = 245,000 \ N/m^2[/tex]
Therefore, the pressure exerted by the girl is 245,000 N/m²

If the sun is 400 times bigger than the moon, how couild the moon possibly cover the sun during a solar eclipse?
Explanation:
the Moon passes between Earth and the Sun Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully block the Sun's light from Earth's perspective This completely blocks out the Sun's light
Answer:
It's all about perspective. The moon is far closer to the Earth than the Sun is, so they appear roughly the same size. If they were closer to each other, then obviously the moon wouldn't be large enough to cover a substantial amount of the sun's light. But given the huge distance both between them and the moon and the earth, to us they look relatively the same.

A 60 kg girl on a swing is pulled 1.5 meters back and then released. The girl oscillates at pi/3 radians per second.How far from equilibrium will the girl be in 4 seconds into the motion
Answer:
-0.75 m
Explanation:
The displacement of the girl is given by x = x₀cosωt where x₀ = maximum displacement of swing = 1.5 m, ω = angular frequency = π/3 rad/s and t = time of swing = 4 s
Substituting the values of the variables into the equation, we have
x = x₀cosωt
x = (1.5 m)cos(π/3 rad/s × 4 s)
x = (1.5 m)cos(2π/3)
x = (1.5 m)cos120°
x = 1.5 m × -0.5
x = -0.75 m
So, the girl is 0.75 m to the left of the equilibrium position 4 seconds into the motion.
A ball hits a wall. What is true about the magnitude of the force experienced by the ball compared with the force experienced by the wall?
A. The ball experiences more force than the wall.
B. The ball experiences less force than the wall.
The ball and the wall experience the same force.
D. The ball experiences half the force of the wall.
Reset
Next
Answer:
The ball and the wall experience the same force.
Explanation:
According to the third law of Newton, which states that "for every action, there is an equal and opposite reaction", this means that when an object 1 acts on object 2 with a certain force, object 2 also acts on object 1 with the same magnitude of force but in an opposite direction.
According to this question, a ball hits a wall with a certain force. This means that the wall will react on the ball with the same force magnitude, but in an opposite manner. Hence, the ball and the wall experience the same force.

Answer:
sry I can't help you In that
A light bulb used in homes converts electrical energy into light energy The amount of light energy output by the lamp in 9.0 hours of use is 23.4 J.
What is electrical energy?The ability of an atom's charged particles to initiate an activity or move an object is known as electrical energy.
The proportion of the device's useful energy transferred to the device's total energy input.
The input power of the light bulb = 52 w.
In 9.0 hours of use.
Hence,
52 x 9.0 = 468 J
The following equation calculates efficiency as a percentage and is represented as follows:
Efficiency is calculated as (Usable Energy Output/Total Energy Input) x 100%.
The lightbulb's efficiency is 5.0%.
(The light energy output/ 468) x 100% = 5%
So, the light energy output = 23.4 J
Therefore, the amount of light energy output by the lamp in 9.0 hours of use is 23.4 J.

An object's period of oscillation can always be used to solve for which 2 points
variable? *
Velocity
Weight
Frequency
Momentum
Answer:
Frequency
Explanation:
A period is the number of revolutions in a minute.
[tex] Period = \frac {time}{number \; of \; oscillations}[/tex]
Also, frequency can be defined as number of oscillation per unit time.
Mathematically, frequency is given by the formula;
[tex] Frequency = \frac {number \; of \; oscillations}{time}[/tex]
Thus, we can deduce that frequency of an oscillation is the inverse of the period (time) of oscillation.
Mathematically, period is expressed as;
[tex] Period = \frac {1}{frequency}[/tex]
This ultimately implies that, an object's period of oscillation can always be used to solve for frequency.

A potential difference of 15 V produces a current of 0.60 amps in a piece of copper wire. What is the resistance of the wire?
9.0 Ω
18.0 Ω
25 Ω
Answer:
R = 25 Ohms
Explanation:
Given the following data;
Voltage (p.d) = 15 V
Current = 0.6 A
To find the resistance of the wire;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
[tex] R = \frac {V}{I} [/tex]
Substituting into the equation, we have;
[tex] R = \frac {15}{0.6} [/tex]
R = 25 Ohms
How much gravitational potential energy does an object have if it is located 20 m above the point that we define as O height and has a mass of 10 kg
Answer:
Explanation:
PE = mgh where m is the mass in kg, g is the pull of gravity which is 9.8, and h is the height of the object above the point to which it could possibly fall, measured in meters. Plugging in:
PE = 10(9.8)(20) so
PE = 1960 J

If the ball is cold, its particles tend to have a small amount of kinetic energy
The particles that make up the ball are moving even when the ball is not.
The temperature of the ball depends on the kinetic energies of the particles that make up the ball.
✔️If the ball is cold, its particles tend to have a smallamount of kinetic energy.
When a substance is hot its particles generally have a large amount of kinetic energy when a substance is cold it's particles do not move as much that means the particles tend to have less kinetic energy.✔️The particles that make up the ball are moving even when the ball is not.
