Answer:
respuesta d)
Explanation:
Answer:
b) 72 F°
Explanation:
In Fahrenheit, the difference between freezing and boiling is 180 F° (that’s 212 °F minus 32 °F). In Celsius, the difference is 100 C° (by definition of 0 °C and 100 °C for those two points). So 100 C° = 180 F°; dividing by 100 gives us 1 C° = 1.8 F°.
So a difference of 40 C° is equal to 40 times (1.8 F°) = 72 F°.
Notice I am using °F and °C for actual temperatures, and F° and C° for temperature DIFFERENCES.
What does this poem mean:
A lake in the spring
Is a marvellous thing
Changes are on the way
The winter chills cease
with sunlight’s increase.
Cool waters cover the bay.
Water moves round
From surface to ground
Water is mixed this way
Spring storms bring rain
Lake water does gain
With nutrients caught in the fray
Tiny creatures abound
‘Cause algae’s around
The food chain is boosted this way.
the poem seems to be about the seasons transitioning from winter to spring. the poet explains the lake melting, the sunlight coming out, spring storms that add water to the lakes, and the creatures that come back to roam after winter comes to an end. im really sorry if that didnt help.

This graph shows the results of an experiment where a rubber ball was dropped and the kinetic energy and the potential energy
were tracked. We know that energy can neither be created nor destroyed, only changed in its form. If the blue line shows kinetic
energy and the red line shows potential energy, what can you infer about the relationship between potential and kinetic energy in.
a bouncing ball? Select ALL that apply.
A)
The total amount of energy is always constant.
B)
When potential energy is its highest, kinetic energy is its lowest.
There is a direct relationship between potential and kinetic energy.
D)
When potential energy is its highest, kinetic energy is its highest.
E)
There is an inverse relationship between potential and kinetic energy.

how long does it take the star and planet to complete one orbit around their center of mass?
Answer:
i think about 225-250 million years
Explanation:
Bottom line: The planets in our solar system orbit (revolve) around the sun, and the sun orbits (revolves) around the center of the Milky Way galaxy. We take about 225-250 million years to revolve once around the galaxy's center. This length of time is called a cosmic year.

X L=V/I=24/1.5=16Ω
L = XL/2πf=16/2π50
= 0.05H
hope this helps you.
Answer:
Hello There!!
Explanation:
I believe the answer is=>5.1 x 10-2H
Here's the explanation:↬
•XL= V/I= 24/1.5= 16Ω
•L= XL/2πf= 16/2π50
So the answer is 0.05H.

Describe what happens when there is Friction and you stop pushing on an object?
Are your answers to questions 1 and 2 the same? Why or why not? What causes that to be the same or different?
I give Brainliest!
Answer: see below
Explanation:
1) An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Friction opposes relative motion. In its absence, a moving object will not stop.
2) If you stop pushing, the force of kinetic friction will produce an acceleration in the opposite direction of the velocity, and the object will slow down and stop.
3) No they are not the same, as one has friction and the other has no friction.

Mia plays soccer for her high school team. Generally, they start practice by stretching. What kind of stretching should they do before they are warmed up?
A.
ballistic stretching
B.
dynamic stretching
C.
flexibility stretching
D.
static-active stretching
PLEASE NO LINKS
The kind of stretching they should do before they are warmed up is dynamic stretching.
What does dynamic stretching mean?
A dynamic stretch is a movement-based type of stretch. It uses the muscle itself to induce stretching. It differs from traditional "static" stretches because the stretch position is not preserved.
Extend your left foot backward, bend your right foot forward and bend it, and rotate left and right to raise your arms to the sky. Or why not stand and add another kind of gentle twist.
Dynamic stretches are based on movement, while static stretches move the joints as much as possible and hold them for a period of time (usually 30-90 seconds).

what is needed to know in a physics exam?
Answer:
Review what you have done for that unit. Skim over it if you dont have enough time because it would greatly help. If you have mathamatics involved learn or make sure you are perfect at doing the equations you need to do. Just dont cheat because if you get caught you are going to get an imediete F which will be worse then getting half of them wrong. Good luck

Explanation:
Electromagnetic Equipment
An electromagnet is a type of magnet with a magnetic field produced by an electric current. Electromagnets are often used in electrical devices that induce heat for cooking such as an oven (OPTION A).
Capacitor
As the voltage increases, the current decreases (OPTION D).
As the capacitor charges up, the potential difference across its plates begins to increase, and by extension circuit current decreases.
