What is net force?????????​

Answer»

Net force is the vector SUM of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces TOGETHER as DESCRIBED by the Newton's second law of motionmark it as BRAINLIEST and follow me

If you go to the beach on a hot day, you may notice that a cool breeze blows from the sea onto the land. Explain why this breeze happens?

Answer»

A SEA breeze occurs due to the difference in TEMPERATURE between the ocean and the land. As land heats up during the afternoon, air above it begins to rise forming a low pressure area near the land. ... As this WARM air is moving over the WATER, the COLDER water causes it to cool off and sink.Explanation:HOPE YOU WILL LIKE MY ANSWER.PLEASE MARK ME AS BRAINLIEST.

Total resistance of diagram​

Answer»

3R/4Method :If you observe closely, there are few wires which doesn't have any resistors CONNECTED across it        Which means that the POTENTIAL is same throughout the wireI.e. across D and C, the 2 resistors are connected in parallel and SIMILARLY  resistors between E and F are connected parallelAfter this, you just add up the resistances in parallel and SERIES accordinglyHope this ANSWER helped you :)

Whuich property of concave mirror is used in making the solar cooker

Answer»

They CONVERGE light to a single point (and so focus the HEAT there)Explanation:Another name for a concave mirror is a converging mirror, which pretty much sums up their purpose: point all the light that hits them on a singe point (the bit where all they rays actually cross each other is CALLED the focal point). At this point, all the Infra Red radiation that has hit them (and been REFLECTED by the mirror's surface) is focussed, and it is this IR radiation that actually does the heating up. Thus, the idea of a solar cooker is to put some food right on top of this focal point to greatly increase the amount of energy that is hitting it, and so heat it up and cook it.Basically, they transfer all the energy that is hitting the large surface of the mirror to a very SMALL spot.

What is gravity?give example​

Answer»

Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth's gravity is what keeps you on the ground and what CAUSES objects to fall.Some examples of the force of gravity include: The force that HOLDS the gases in the sun. The force that causes a ball you THROW in the air to come down again. ... The force that causes the MOON to revolve AROUND the Earth.                          ()HOPE<>IT<>HELPS<>YOU()
