ANSWER:

Explanation:

6km=60000cm

4 MINUTES =240 sec

SPEED =distance/time

=60000cm/240s

=250cm/s

So speed is 250cm/second

ANSWER:

Heat is a FORM of energy which causes sensation of hotness and coldness

Answer:

WATER cycle is a natural change

1) water is physical change because there is no NEW substance is formed.

2) water is a reversible change because we can reverse it. for EXAMPLE ( when we freeze water , it CHANGES into ice , when ice cools down, it again changes into water and when we heat water , it changes into steam and when steam cools down , it again changes into water.

Climate change" redirects here. For a discussion of climate trends throughout Earth's history, see Climate variability and change. For other uses, see Climate change (disambiguation).

Average global temperatures from 2010 to 2019 compared to a baseline average from 1951 to 1978. Source: NASA.

The rising average temperature of Earth's climate system, called global warming, is driving changes in rainfall PATTERNS, extreme weather, arrival of seasons, and more. Collectively, global warming and its effects are known as climate change. While there have been prehistoric periods of global warming, observed changes since the mid-20th century have been unprecedented in rate and scale.[1]

Observed temperature from NASA[2] vs the 1850–1900 average as a pre-industrial baseline. The primary driver for increased global temperatures in the industrial era is human activity, with natural forces adding variability.[3]

The Intergovernmental Panel on Climate Change (IPCC) concluded that "human influence on climate has been the dominant cause of observed warming since the mid-20th century". These findings have been recognized by the national science academies of major nations and are not disputed by any scientific body of national or international standing.[4] The largest human influence has been the emission of GREENHOUSE gases, with over 90% of the impact from carbon dioxide and methane.[5] Fossil fuel burning is the principal source of these gases, with AGRICULTURAL emissions and deforestation also playing significant roles. Temperature rise is enhanced by self-reinforcing climate feedbacks, such as loss of snow cover, increased water vapour, and melting permafrost.

Land surfaces are heating faster than the ocean surface, leading to heat waves, wildfires, and the expansion of deserts.[6] Increasing atmospheric energy and rates of evaporation are causing more intense storms and weather extremes, damaging infrastructure and agriculture.[7] Surface temperature increases are greatest in the Arctic and have contributed to the retreat of glaciers, permafrost, and sea ice. Environmental impacts include the extinction or relocation of many species as their ecosystems change, most immediately in coral reefs, mountains, and the Arctic. Surface temperatures would stabilize and decline a little if emissions were cut off, but other impacts will continue for centuries, including rising sea levels from melting ice sheets, rising ocean temperatures, and ocean acidification from elevated levels of carbon dioxide.[8]

Mitigation efforts to address global warming include the development and deployment of LOW carbon energy technologies, policies to reduce fossil fuel emissions, reforestation, forest preservation, as well as the development of potential climate engineering technologies. Societies and governments are also working to adapt to current and future global warming impacts, including improved coastline protection, better disaster management, and the development of more resistant crops.

Countries work together on climate change under the umbrella of the United Nations Framework Convention on Climate Change (UNFCCC), which has near-universal membership. The goal of the convention is to "prevent dangerous anthropogenic interference with the climate system". The IPCC has stressed the need to keep global warming below 1.5 °C (2.7 °F) compared to pre-industrial levels in order to avoid some irreversible impacts.[10] With current policies and pledges, global warming by the end of the century is expected to reach about 2.8 °C (5.0 °F).[11] At the current greenhouse gas (GHG) emission rate, the carbon budget for staying below 1.5 °C (2.7 °F) would be exhausted by 2028.[12]

What is the formula for the equivalent resistance RT of the THREE RESISTORS r1 r2 & r3 are connected in parallel circuit?

Here the supply POTENTIAL is VAB between the points A and B. Since the resistors R1, R2 and R3 are connected in parallel COMBINATION the potential difference across each resistor is same as the supply. Hence VAB = VR1 = VR2 = VR3. VR1 is the potential across the resistor R1.

ROLLING resistance

"Rolling resistance is the friction, that comes into play, when a BOOK, kept on a collection of cylindrical pencils, is moved by PUSHING it. Rolling resistance, also called rolling friction or, is the force RESISTING the motion when a body rolls on a surface.

(a) Sound is produced by buzzing the lips.

The TRUMPETER produces sound from the trumpet by buzzing his lips. There are various different MOUTHPIECE shapes-a mouthpiece with a DEEP cup will produce a mellower sound, while a mouthpiece with a shallower cup will produce a bright, piercing sound.

(b) The vibration of the head shakes the entire drum.

Striking the head of the drum changes its shape and COMPRESSES the air inside the shell. These VIBRATIONS of the top and bottom heads create vibrations in the air, which become sound, and eventually, as the head vibrations are dampened, the sound diminishes.

Adrenaline hormone is secreted in LARGE amounts when a person is frightened, or mentally disturbed.

When it reaches the heart, it beats FASTER to supply more oxygen to our MUSCLES.

The BREATHING rate also increases because of the contractions of diaphragm and the rib muscles.

It also raises the blood pressure, and allows more glucose to enter into the blood.

All these responses together enable our body to deal with the emergency situations.

Adrenaline is a hormone secreted when a person is frightened or mentally disturbed. When Adrenaline reaches heart, HEARTBEAT will increase to increase blood supply to our muscles. Adrenaline also increases the breathing rate because of contraction of diaphragm and the rib muscles. Adrenaline rush also increases blood pressure and allows entry of more glucose into blood. These altogether occurs when our body respond to secretion of adrenaline into our blood.

Usage of Iodized SALT is advisable to AVOID the deficiency of Iodine. If the intake of iodine is low, the release of thyroxine from the THYROID gland will be decreased.

This affects fat, carbohydrate and protein metabolism.

Thus a person may have goitre PROBLEM in CASE if the intake of iodine is lowered.

AUXINS and Gibberlins are the hormone RESPONSIBLE for the growth of plant.

Auxins are responsible for the CELL ELONGATION in shoot and ALSO regulates growth.

Gibberlin is responsible for stem elongation and germination.

Reflex action are the involuntary actions that occur in response to stimuli. They occur without involvement of CONSCIOUS areas of brain. All the reflex actions are UNCONSCIOUS actions. Reflex action occurs brain and spinal CORD of central nervous systems.

Answer:

Newton's laws of motion are three PHYSICAL laws that, together, laid the foundation for classical mechanics. They describe the RELATIONSHIP between a body and the forces acting upon it, and its motion in response to those forces. In the first law, an object will not CHANGE its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its ACCELERATION. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
