Answer:
The loss of balance while standing on a bus often is due:
Explanation:
The third Newton law from Latin says: "Action is always opposed an equal reaction: or the two bodies on each other are always equal, and in opposite directions," which means that when a force is exercised in a direction by a body, the other body in the interaction exercises a force in the other direction. In the case of the person on the bus, when the bus makes a force forward, your body makes a force in the other direction (back), in a similar case, when the bus stops, its force in directed to the back, in that time your body make a force forward, in each case your body can lose balance because your center of gravity is directed in the same direction in which the opposite force to that of the bus moves.
A ball is fired with speed v = 180 m/s at an angle 40 degree
So here we can say the components of velocity is given as
now when ball will reach the maximum height its velocity in vertical direction will become zero
so here we can say
now using kinematics we will have
so maximum height is
so it will reach at maximum height of 683 m
nuclear energy
B.
electrical energy
C.
chemical energy
D.
sound energy
The correct answer to the question is : C). Chemical energy.
EXPLANATION:
A gas stove provides energy when the gas present inside it, is burnt.
The gas contained inside it are natural gases which contain chemical energy. When gases come under fire or electric spark, the chemical energy is converted into light and heat energy.
No nuclear, electric or sound energy are consumed in providing power .
Hence, the correct statement is chemical energy.
