Answer:
Nervous system messages travel through neurons as electrical signals. When these signals reach the end of a neuron, they stimulate the release of chemicals called neurotransmitters. Neurotransmitters travel across synapses, spaces between neurons or between neurons and other body tissues and cells.

A wave can travel through a solid, liquid or gas or no matter at all
True or false?
TRUE or FALSE: An object's mass changes depending on which planet it is located.
A. TRUE
B. FALSE
Answer:
Fales
Explanation:
That's why scientists and engineers often measure an object's mass—how much matter the object contains—rather than its weight. Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity.

Two masses oscillating together with each of their time period as ,'T'
To find↷New time period ,'T'Answer↷Option B
Time period is independent of mass so it will remain same irrespective of the mass on the spring so the new time period would be the exact same as the previous one.Solution↷we know that,
The time period of a mass 'm' on a spring of spring constant 'k' can be strategize by the following equation :
[tex] \huge \rightarrow \: T \: = 2π \sqrt{ \frac{m}{k} } [/tex]
m⇢mass of the body [kg]k⇢spring constant [Nm^-1]According to the question,
The new mass would be 2mThe new spring constant would be 2kso,
The new time period would be
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{2m}{2k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{m}{k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = T[/tex]
Hence ,option B is correct ✓
What were the organic compounds Professor Wadhwa found and why are they important?
Answer:
Organic compounds are important because all living organisms contain carbon. They are the basic components of many of the cycles that drive the earth. For example, the carbon cycle that includes the exchange of carbon between plants and animals in photosynthesis and cellular respiration.
Which explanation BEST supports Newtons second law of motion
Answer:
c
Explanation:
because newton's second law states that F= MA
which suggests that if M increases, F also increases which is the force,
let me give you a tip, during exam, just type any random numbers into the formula, like at first you type 5 into the M, then increase M, by putting 10 into the M , keep the acceleration the same for this, okay?
you will see that the force will increase,
by this I mean that option says largest mass, so the force will also be very big because in reality do you use more force on heavier box or a lighter one to push it across the room?
so larger mass, larger force, greater acceleration
but the question is not being clear, whether to the force remains constant for every object, if it does then A is false . and B is false because if the forces is constant, and it is light, it would require a small amount of force ,
but the other options, gave us a clue about the force so you can choose either c or d but see the explanation above,
the only corrext option will be c.
if not, please report this, someone will have a go at it

Why does the North star not move but the other stars move
Answer:
it's the star in the center of the star field
Explanation:
Why Doesn't Polaris Move? Polaris is very distant from Earth, and located in a position very near Earth's north celestial pole. ... Polaris is the star in the center of the star field; it shows essentially no movement. Earth's axis points almost directly to Polaris, so this star is observed to show the least movement

Determine the acceleration of a car of mass 900 kg, when a net force of 2700 N acts on it.
you push a freezer with a force of 250 N. if you move it a distance of 15 m, how much work was done?
Answer:
375J
Explanation:
W=F x d
=250 x 15
=375J
The work W is equal to the force f times the distance d, or W = fd, to mathematically describe this idea. If the force is applied at an angle to the displacement, the work is W = fd cos.
What force is related to work done?Work in physics is the energy that is transferred to or from an item when a force is applied along a displacement. In its simplest form, For a constant force that is oriented in the same direction as the motion, it is easiest expressed as the product of the force's magnitude and the distance travelled.
A desk is being subjected to applied force if someone is pushing it across the room. The person's force applied to the desk is known as the applied force.
Mass and weight are not the same.The normal force is the supporting force exerted on an object when it collides with another stable object.
Therefore, W=F × d =250 × 15 =375J

Answer:
Coal is fossil fuel extracted from earth and since it takes a long time to replenish, it is called a non renewable source of energy
Explanation:
Coal is formed from the fossil fuel that lie deep beneath the earth crust . These fossil fuels are dead remains of living organism that burried beneath the earth crust million of years ago.
Coal is non renewable because if once it gets depleted it will take a very very long time to replenish.

According to Newton’s second law of motion, what is equal to the acceleration of an object?
Answer:. The acceleration of the object is directly proportional to the force and inversely proportional to the mass.
Explanation:
According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration.

You skip north for 12 minutes to your best friend's house that is 1.5 kilometers away. What is your average velocity?
Answer:
The average velocity is 7.5 km/h
Explanation:
Were Gonna convert minutes to hours
12 minutes = 12/60 hours = 0.2 hours

why are north and south poles important to magnets
Answer:
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.
