Which of the following occurs during the process of a liquid changing to a gas (boiling)?
The temperature increases.
The temperature remains the same.
The temperature decreases.
Answer:
the process that occurs when liquid changes to gas(boiling) is temperature increases
Answer:
The temperature increases
Explanation:
When a substance is converted from liquid state to gaseous state the particles get excited.The excitement raises the temperature of the substance_______is the force that keeps us all stuck to the surface of our planet.
Answer:
gravity
Explanation:
What is the total distance travelled? What is the displacement of the object?
Hi there!
Distance and displacement are different.
Distance is WITHOUT direction (scalar quantity)
Displacement TAKES INTO ACCOUNT direction (vector quantity), and is RELATIVE to the initial point.
DISTANCE:
Add up each segment's position:
0 - 2 sec: 0 m
2 - 5 sec: 10 - 4 = 6 m
5 - 6 sec: 0 m
6 - 8 sec: 10 - 2 = 8 m
8 - 9 sec: 0 m
9 - 12 sec: 5 - 2 = 3 m
Add up:
6 + 8 + 3 = 17 m
DISPLACEMENT:
To find displacement, simply look at the position at the final point (t = 12 sec) and compare to the initial position:
At t = 12: Position = 5 m
At t = 0: Position = 4 m
5 - 4 = 1 m

Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to____
which aided in the formation of____
1. A.Increase
B. Decrease
C. Remain constant
2. A. Chloroplast
B. Roots
C. Soil
Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to increases which aided in the formation of soil.
What is photosynthesis ?The process in which use of solar energy occur by plants, algae and certain bacteria convert them into chemical energy and starch called as photosynthesis.
Photosynthesis occur in chloroplast of the green plant which has its own DNA, genes and synthesize their own proteins.
photosynthetic Pigments are also involve in this process which is responsible for trapping sunlight present in chlorophyll pigment of chloroplast, like chlorophyll a, b and c.
some of the Bacteria have chlorophyll known as bacteriochlorophyll which can absorb infrared rays, Carotenoids which are yellow, orange or red-coloured pigments that absorb bluish-green light., Xanthophyll, Phycobilins.

why do we place window downward and ventilation upward?
Answer:
Doors, Windows & Ventilator is a part of building component which is allow to Air & light move & circulate inward & outward, with in door Human or any other material can be move inside or outside also. here types of doors & windows & ventilation are given with necessity of location, function etc.
Window ventilators are used for ensuring a supply of fresh air from the outside into the interior. They are used in rooms with natural ventilation, mechanical extract ventilation or hybrid ventilation. ... It automatically adjusts the inflow of fresh air depending on the level of relative humidity in the room.
Explanation:
what do the astrometric, doppler, and transit methods share in common?
They all search for planets by measuring properties of a star rather than of the planets themselves. ... The size of the Doppler shift that we detect depends on the tilt of a planet's orbit.

Explain swimming based on one of the laws of motion?
Answer:
Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. Thus, swimmers must stroke downward in the water to stay afloat and propel forward. This movement is equal and opposite to the force the water exerts against the swimmer to stop them from moving.

Describe in your own words a situation where chemical energy is transformed to potential energy.
Answer:
The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move. Eventually, most of energy used by organisms is transformed into heat and dissipated.

A new model BMW can start from rest and travel 400 m in 16 s. a. What is its acceleration during this time? [2] b. Calculate the final speed of the car. [2] c. How fast is this final speed in km/h?
Answer:
acceleration = 3v 125 m/s^
final speed= 50 m/s
final speed in km/hr = 180 km/hr
Explanation:
A new model BMW can start from rest and travel 400 m in 16 s.then the acceleration during this time would be 1.5625 m/s²
What are the three equations of motion?There are three equations of motion given by Newton
The first equation is given as follows
v = u + at
the second equation is given as follows
S = ut + 1/2×a×t²
the third equation is given as follows
v² - u² = 2×a×s
As given in the problem, A new model BMW can start from rest and travel 400 m in 16 s
distance covered by BMW = 400meters
initial velocity(u) = 0 m/s
time = 16 seconds
acceleration(a) =? m/s²
By using the second equation of motion given by newton
S = ut + 1/2at²
S = 400 m ,u= 0 m/s , and t =16seconds
400 = 0 + a16²
a =400/256
a = 1.5625 m/s²
For the final speed of the car
v= u + at
v = 0 + 1.5625×16
v = 25 m/s
For calculating the speed in km /h
v = 25 ×3600/1000
= 90 km/h
Thus, the acceleration during the first 16 s time would be 1.5625 m/s²

How much work is done on an object that is moved to acquire a displacement of 5 meters when 500 Newtons of force was exerted?
Answer:
2,500 Joules (J) or Newton Meter (N M)
Explanation:
Work = Force x Distance
The force in this equation is 500 Newtons. The distance (displacement) is 5 meters. Plug it into the equation above.
Work = 5m x 500n
Work = 2,500 Joules or Newton-Meters.
Therefore 2,500 Joules or Newton Meters of work is done on an object.
