Answer:48.2 Joules
Explanation:
Given
two masses of 0.2 kg and 0.4 kg collide with each other
after collision 0.2 kg deflect 30 north of east and 0.4 kg deflects 53.1 south of east
Velocity of 0.2 kg mass is
Velocity of 0.4 kg mass
Thus total Kinetic energy 
Kinetic energy=48.2 J
Answer:The factors which are used to calculate the kinetic energy of an object are mass and velocity. Explanation: The kinetic energy is the energy of the motion of an object. Here, m is the mass of the object and v is the velocity of the object.
Explanation:
hope it helps
Velocity = Distance / time taken
= 110 m /72s
1.52 ms⁻¹
Answer:
C. Plants converting sunlight into chemical energy.
Explanation:
An "endothermic reaction" is a process whereby <em>energy coming from the surroundings is being absorbed as heat.</em> This activates the reaction to occur. Since it absorbs the heat to start the reaction, then it can be classified as an endothermic reaction.
When plants convert sunlight into chemical energy, it absorbs the sunlight as a light energy on its chlorophyll. This is where photosynthesis occur. This then results to the chlorophyll reacting with the carbon dioxide, water and the energy which results to the production of <em>oxygen and glucos</em>e.
So, this explains the answer.
