find the value (-121) ÷ (-11)​

Answer:

Explanation:

Greenhouse gases trap heat in the atmosphere so they help to moderate global temperatures. Without an atmosphere with greenhouse gases, Earth's temperatures would be frigid at night and scorching during the day. Important greenhouse gases include carbon dioxide, methane, water vapor, and ozone.

Answer:

People across India are facing critical drought conditions and water shortages. As of June 25, 2019, nearly 65 percent of the country’s reservoirs were running dry. One of the worst affected areas has been the west-central state of Maharashtra, where six of the 17 reservoirs are dried out.

Explanation:

1. Rajasthan -  Rajasthan’s situation is a perennial problem due to the geography of the state

2. Utter Pradesh- This kind of water scarcity primarily arises due to the lack of water infrastructure in general or due to the poor management of water resources where the infrastructure is in place.

3. Madhya Pradesh-  The acute water crisis, caused by the prevailing heatwave conditions, has triggered a mass migration of people from many villages in the parched belt of Bundelkhand in Madhya Pradesh.

4. Gujarat- Groundwater is also polluted as a result of indiscriminate industrial dumping, causing a freshwater scarcity in the region. In Gujarat, even regions with otherwise plentiful surface water sources are affected as creeks and rivers turn into black cesspools thanks to increasing municipal waste and insufficient sewage treatment plants.

5. Maharastra- Following years of drought, the rivers’ currents have ebbed, water in dams and reservoirs has depleted and over-exploitation of groundwater has raised concerns over the long-term availability of water.

6. Chattisgarh- Caused by the prevailing heatwave conditions.

7. Telengana- Acute drinking water shortage due to drastic fall in water levels in major reservoirs, continuing crisis in agriculture, and a harsh summer have made this the worst ever drought in Telangana, in living memory.

8. Anda Pradesh-  Andhra Pradesh is staring at a major drinking water crisis this summer, as reservoirs in the state have no inflows and the water levels reduce.

9. Tamil Nadu- Tamil Nadu is facing a severe water crisis. The reason behind the current water crisis is the recent monsoon failure. The very high temperature that Chennai is facing right now is because of the lakhs of trees uprooted by cyclone Vardha.

Explanation:

1 Repulsion

2 Demagnetisation

Answer:

Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces.

Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used

The two primary issues involved in magnetic levitation are lifting forces: providing an upward force sufficient to counteract gravity, and stability: ensuring that the system does not spontaneously slide or flip into a configuration where the lift is neutralized
