The muscular system and the skeletal system of the human body work together toA. allow movement.
B. perform respiration.
C. transport nutrients.
D. protect the integumentary system.

Answers

A. Allow movement.
Muscles connect to your skeleton and they contract and move the skeleton along. They help the process of movement happen in a smoother manner.

A. Because they connect together for movement of the body.

If a turtle walks at a constant speed of 0.23 m/s, how long will it take to cover a distance of 65 meters?

Answers

Time = (distance) / (speed)

Time = (65 meters) / (0.23 m /s)

Time = (65 / 0.23) sec

Time = 282.6 seconds ( that's 4 minutes 42.6 seconds)

Final answer:

The time it would take a turtle moving with a speed of 0.23 m/s to cover a distance of 65 meters is approximately 282.61 seconds.

Explanation:

The subject of this question is physics, specifically the concept of speed, distance, and time. The formula that relates these three quantities is speed = distance/time.

In this case, we are asked to calculate the time it would take for a turtle moving with a constant speed to cover a certain distance. Here, the given speed (0.23 m/s) of the turtle and the distance it needs to cover (65 meters) are known.

By rearranging the formula to solve for time, we get time = distance / speed. Plugging in the values, we get time = 65 meters / 0.23 m/s. Doing the math gives approximately 282.61 seconds. Thus, it would take the turtle around 283 seconds to cover the distance of 65 meters at a speed of 0.23 m/s.

Can you explain that gravity pulls us to the Earth & can you calculate weight from masses on both on Earth and other planets?

Answers

I don't actually understand what your question is, but I'll dance around the subject
for a while, and hope that you get something out of it.

-- The effect of gravity is: There's a pair of forces, in both directions, between
every two masses.

-- The strength of the force depends on the product of the masses, so it doesn't matter whether there's a big one and a small one, or whether they're nearly equal.
It's the product that counts. Bigger product ==> stronger force, in direct proportion.

-- The strength of the forces also depends on the distance between the objects' centers. More distance => weaker force. Actually, (more distance)² ==> weaker force.

-- The forces are equal in both directions. Your weight on Earth is exactly equal to
the Earth's weight on you. You can prove that. Turn your bathroom scale face down
and stand on it. Now it's measuring the force that attracts the Earth toward you.
If you put a little mirror down under the numbers, you'll see that it's the same as
the force that attracts you toward the Earth when the scale is right-side-up.

-- When you (or a ball) are up on the roof and step off, the force of gravity that pulls
you (or the ball) toward the Earth causes you (or the ball) to accelerate (fall) toward the Earth.
Also, the force that attracts the Earth toward you (or the ball) causes the Earth to accelerate (fall) toward you (or the ball).
The forces are equal. But since the Earth has more mass than you have, you accelerate toward the Earth faster than the Earth accelerates toward you.

-- This works exactly the same for every pair of masses in the universe. Gravity
is everywhere. You can't turn it off, and you can't shield anything from it.

-- Sometimes you'll hear about some mysterious way to "defy gravity". It's not possible to 'defy' gravity, but since we know that it's there, we can work with it.
If we want to move something in the opposite direction from where gravity is pulling it, all we need to do is provide a force in that direction that's stronger than the force of gravity.
I know that sounds complicated, so here are a few examples of how we do it:
-- use arm-muscle force to pick a book UP off the table
-- use leg-muscle force to move your whole body UP the stairs
-- use buoyant force to LIFT a helium balloon or a hot-air balloon
-- use the force of air resistance to LIFT an airplane.

-- The weight of 1 kilogram of mass on or near the Earth is 9.8 newtons. (That's
about 2.205 pounds). The same kilogram of mass has different weights on other planets. Wherever it is, we only know one of the masses ... the kilogram. In order
to figure out what it weighs there, we need to know the mass of the planet, and
the distance between the kilogram and the center of the planet.

I hope I told you something that you were actually looking for.

Answers

Iron shavings ,compass and galvanometer use to determine the direction of the magnetic field lines around a magnet.

What is electromagnet?

An electromagnet is a magnet whose magnetic field is generated by an electric current. Wire coiled into a coil is used to make electromagnets.

A current flowing through the wire produces a magnetic field that is focused in the hole.

A tiny compass may be used to map out magnetic field lines. As illustrated, The compass is moved from point to point around a magnet, with a small line drawn in the direction of the needle at each point.

The course of the magnetic field line is then shown by joining the lines together.

Hence, iron shavings ,compass and galvanometer use to determine the direction of the iron magnetic field lines around a magnet.

A wave has a low speed but a high frequency. What can you infer about its wavelength?

Answers

The amount of the wave length is inversely proportional to its frequency and directly to its speed. So in your question, the amount of wavelength with a low speed and high frequency has a low value or quality of wavelength output. If your frequency would get high but the speed is just low the wave length is still low
