The statemengt is <em>false</em>. Electromgnetic waves do not require a medium to transfer energy. They can transfer energy through vacuum (empty space with nothing in it). If electrimagnetic waves needed a medium to move through from place to place, then we could never see the sun, and also it would get very cold here.
Answer:
Energy is measured in JOULES.
Atoms and molecules are the fundamental building blocks of matter.
Explanation:
Matter is anything that has weight and occupies space. Locked within any given molecule or atom is some form of energy waiting to be activated. Energy can neither be created nor destroyed.
Answer: Objective Observations
Explanation: The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false
1. Use renewable energy sources (eg. wind, solar etc.)
2. Encourage citizens to use public transport
3. Better waste management systems (instead of burning waste, recycle etc.)
that’s all i could think of :)
given that
initial velocity of car = 0 m/s
after t = 10 s
final velocity of the car = 25 m/s
now for average acceleration we can use
<em>so here the acceleration will be 2.5 m/s^2</em>
