Areas with mountains are warmer than other areas at the same latitude.
Answer:
Places at the same latitude may have very different climates if one is on a coast and one is inland. On the coast, the climate is influenced by warm moist air from the ocean. A coastal climate is usually mild. ... Farther inland, the climate is influenced by cold or hot air from the land.
Explanation:
Hopefully its correct!
The statement 'areas with mountains are warmer than other areas at the same latitude' is FALSE.
At high altitudes, the temperature is colder than in areas closer to the sea level.
At higher altitudes, there are fewer air molecules in a specific surface area than in the same area at lower levels. Thus, as air rises, the air pressure decreases.
This lower air pressure causes the temperature to be colder at high altitudes than at sea level.
In conclusion, the statement 'areas with mountains are warmer than other areas at the same latitude' is FALSE.

A golden-colored cube is handed to you. The person wants you to buy it for $100, saying that is a gold nugget. You pull out your old geology text and look up gold in the mineral table, and read that its density is 19.3 g/cm3. You measure the cube and find that it is 2 cm on each side, and weighs 40 g. What is its density? Is it gold? Should you buy it?
Answer:
Explanation:
Volume of cube=side³
=2*2*2
=8 cm³
Mass of cube=40g
Its density=mass/volume
=5g/cm³
which differs the value given in the text hence it is not gold and u should not bye it...
Instead u should call the police for arresting the person lol...
this is for science class Gravity and Mass vs. Weight Notes
Answer:
Explanation:
There are two factors that affect gravity: mass and distance.
Law of Gravity: Every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Gravity: the force by which each object draws all the other objects towards its center.
Gravity is affected by mass and distance.
Everything with mass has gravity.
The more mass an object has, the more gravity it has.
The farther you are from the source of gravity, the lesser of gravity you will feel.
In space, your weight will read 0 and the objects in space are hard to move due to the different gravitational forces acting upon each object from different areas.
Weight: Weight is the force of gravity on an object.
Weight is completely dependent on gravitational force acting on an object.
The more gravity there is, the more weight an object will have.
Mass and weight are not the same.
Mass does not change because it is the amount of matter in an object which does not change no matter where the object is. However, weight changes because it is the effect of gravity on an object.
In order to find weight, use the formula W=mg where W is the weight, m is the mass and g is the gravitational force.

calculate the mass of a child if it gains 600j of gpe when it climbs up of height 3m
Answer: 20kg
Explanation: the above question is base on workdone...
Note: work done is also equal to potential energy.
➡Mathematical expression for the above statement:
W = P.E. where w and p.e are noted to be work done and potential energy...
Therefore; P.E = mgh
Where m is the mass of the object, g is the acceleration due to gravity and finally h is the height...
Therefore; P.E = mgh
600 = m x 10 x 3
600 = 30m
Divide both side by the coefficient of m
Therefore; 600/30 = m
m = 20kg
Answer:
mass = 20.408 kg
Explanation:
Formula: GPE = mgh
Solve:
600 = m*9.8*3
600 = m*29.4
m= 600/29.4
m= 20.408 kg
Result:
20.408 kg
Benefits from fission as energy

It can provide cheap energy resources for the planet. ...
It offers a low-emission energy solution. ...
It works for extended periods of time. ...
It is a reliable source of energy. ...
It provides high concentrations of energy. ...
It has the lowest annual mortality rate of any energy resource.
Explanation:
Explanation:
Low-cost energy
Although building nuclear power plants has a high initial cost, it’s relatively cheap to produce energy from them and they have low operating costs.
Reliable
One of the biggest benefits of nuclear energy is that it is a reliable power generation source.
Zero-carbon emissions
Nuclear power reactors do not produce any carbon emissions. This is a huge advantage over traditional sources of energy, like fossil fuels, which releases tons of carbon dioxide into the atmosphere.
Nuclear fusion is the holy grail of harnessing energy. If we can learn to control atomic fusion (the same reactions as those that fuel the sun), we could practically have unlimited energy.
High energy density
It is estimated that the amount of energy released in a nuclear fission reaction is ten million times greater than the amount released when burning fossil fuels

What happens to the compass needle as you move the compass around?
A.The compass needle always points north
B.The compass needle points in random directions.
C.The compass needle follows the pattern of magnetic field lines
D.THE compass needle's north pole always points to the north pole of the magnet
When the compass needle as you move the compass around, Then the compass needle follows the pattern of magnetic field lines. The correct option is C.
What is the pattern of magnetic field lines?
Magnetic field lines are imaginary lines used to represent the direction and strength of the magnetic field around a magnet or a current-carrying wire. The pattern of magnetic field lines depends on the shape and orientation of the magnet or the wire, as well as the direction and strength of the magnetic field.
The magnetic field lines around a magnet emerge from the north pole and loop back into the south pole in a continuous path. They are always closed loops, meaning they do not begin or end anywhere but instead form a continuous path around the magnet. The magnetic field lines are closer together near the poles of the magnet, indicating a stronger magnetic field in those regions. They become less dense as they move further away from the poles, indicating a weaker magnetic field in those regions.
Here in the question,
When a compass is moved around, the compass needle aligns itself with the direction of the magnetic field lines in the vicinity. Magnetic field lines are the paths that a small compass would follow if it were placed at various points around a magnet. They indicate the direction of the magnetic field at each point.
The compass needle has a north-seeking pole and a south-seeking pole. The north-seeking pole of the compass needle aligns itself with the direction of the magnetic field lines, which are oriented from the north pole of a magnet to the south pole. This means that the north-seeking pole of the compass needle will point towards the south pole of a magnet, while the south-seeking pole of the compass needle will point towards the north pole of the magnet.
Therefore, as the compass is moved around a magnet or any other magnetic field, the compass needle will follow the pattern of the magnetic field lines, and the north-seeking pole of the compass needle will always point towards the south pole of the magnet or the magnetic field source.

The photo shows a clay pot being made on a spinning potter's wheel. Which change would increase the pot's angular velocity?
A. Shape the pot so that it has a narrower base and the same size rim.
B. Shape the pot so that it has the same size base and a wider rim.
C. Shape the pot so that it has a wider base and a wider rim.
D. Shape the pot so that it has a wider base and the same size rim.
The angular velocity of the piece of clay increases to shape the pot so that it has a narrower base and the same size rim. Therefore, option (A) is correct.
What is the angular velocity?Angular velocity can be described as the velocity of an object to move within a speed w.r.t. its center of rotation. Angular velocity is equal to the angular displacement, which is theta.
The mathematical formula to determine angular velocity is:
ω =Δθ/Δt
where ω is the angular velocity, Δθ is the change in angular rotation and Δt is the change in time.
The angular velocity of an object would increase if the shape of the pot has a narrower base and the same size rim. Because the angular velocity of an object which is narrow would have greater.
Thus, the correct option is A. The shape of the pot is so that it has a narrower base and the same size rim.

Why is it important for the path of a circuit to be circular?
Answer:
When the platform rotates, the rotating mass will travel in a circular path due to the force exerted on it by the string (by way of the tension in the spring). Since it is not possible to have an instantaneous readout of this tension force while the platform is rotating, an indirect measurement of this force will be made using the weight of the static mass as shown and explained below.
