    Joule's law of heating states that when a current 'i' passes through a conductor of resistance 'r' for time 't' then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time.

    Power = electric energy

    time

    Power×time=electric energy

    electric energy =P ×t

    H=IR×It

    H=I2 Rt

    The total movement of an object or a body without any regards to direction.

    0Thank You

    Yogita Ingle 5 years, 7 months ago

    Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.

    Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position. For Example- If an object moves from A position to B, then the object’s position changes. This change in position of an object is known as Displacement.

    When acids and bases react, they result in the formation of salt and water as product and this reaction is called neutralization reaction. In our everyday life we come across many situations which involve neutralization reactions. The following examples will illustrate common neutralization reactions that occur around us.

    During indigestion, too much of acid is produced inside the stomach resulting in stomach disorder or acidity. In order to retrieve the pain we take bases such as milk of magnesia which contains magnesium hydroxide. Taking a base neutralizes the effect of excess acid.

    Second is the effect of ant sting which is caused by formic acid which is neutralized by rubbing moist baking soda (basic in nature) which contains zinc carbonate.

    In a physical change, the molecules are rearranged while their actual composition remains same

    Some example of physical change are freezing of water, melting of wax, boiling of water, etc.

    In a chemical change, the molecular composition of a substance completely changes and a new substance is formed.

    A few examples of chemical change are digestion of food, burning of coal, rusting, etc.

    yes it is possible a body velocity can zero an acceleration is constant but it will be negative will be negative because when we throw a ball at a point the ball will stop and that time The velocity is zero but the acceleration of the gravity of the earth will be always negative and it will be 9.8 Newton

    2Thank You

    Madhur Sahay 5 years, 8 months ago

    a) not possible. Acceleration is v/t. So if v=0 , then acceleration is also 0 b) This is possible in circular motion where velocity is perpendicular to acceleration. c) Every object starts from 0 and accelerates to a particular speed remaining it at constant
