Answer:
A battery works because of the electrical energy inside of the battery, which is connected through a wire, which transmits energy through the metal inside of the wire to power to object that the wire is connected to.

I believe it's 2. I am not sure though.
Answer:
We feel the door pushing on the right side of our body because we lean suddenly towards the right side when an abrupt turn is taken by the car due to the inertia of our body mass.
Explanation:
Inertia is the property of a body in accordance with the Newton's first law of motion by the virtue of which it continues to be in the state of rest or in uniform motion until acted upon by an external force. <em>Greater the mass of a body, greater is its inertia.</em>
In this case when sitting in a car traveling on a straight path we have a constant velocity. When all of a sudden there is a change in direction then our inertial tendency of moving in a straight linie with a certain velocity is disturbed by the rate of change in momentum which is responsible for the force according to the Newton's second law of motion.
This also happens because our lower part of body is directly in contact with the seat of the car while the upper part is not. So, when there is an abrupt change in the velocity we experience a lag in the weight transfer which is always in the opposite direction of the change in motion.
This effect can be clearly visible when we move along with a half filled bottle of a liquid which will show the effects of transition in a sensitive manner detecting very small changes.
Answer:
It will travel 350 meters each second.
Explanation:
The unit rate, 350 m/s, tells us that the jet will travel 350 meters per every second elapsed.
The convection can occur most likely in liquids and gases.
Explanation
The process of heat transfer can be classified in three types:
(i) conduction,
(ii) convection and
(iii) radiation.
Mostly we term the mechanism of heat transfer as conduction which occurs in solids.
The densely packed atoms in solids vibrate when heat energy is applied on them and while vibrating the atoms will transfer energy from one atom to another atom on collision. This is the mechanism in conduction.
But in liquids and gases , the probability of collision of vibrating atoms are very less as the atoms are loosely arranged in liquids and gases. So in them convection method is used for the transfer of heat energy.
The heat energy will be carried by the molecules while moving in their path and thus the heat energy will be transferred by convection in liquids and solids.
