Answer:
1.The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.
2. As the combustible materials burn, some of the chemical energy is transformed into heat energy, and some is transformed into light energy. Light energy, also known as radiation or electromagnetic energy, is a type of kinetic energy that takes the form of visible light waves, such as the light from a match
3. Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
4. Answer: Refraction is the bending of light (it also happens with sound, water, and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms, and rainbows. Explanation: Refraction.
5. The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
Answer:
the two organelles found only in plants include chloroplasts and cell wall.
Explanation:
cell wall is the outermost boundary in most plant cells while animal cells lack it .but the cell wall of plant cells is different from that of prokaryotic cell wall, both in structure and chemical composition.CELL WALL prevents the osmotic lysis of plants and provides them a definite shape. another organelle found only in plants is the CHLOROPLAST. choloroplasts are the type of plastids which are not found in animal cells .choloroplast contain a green pigment called chlorophyll which halp in PHOTOSYNTHESIS. in adition to these plants also contain GLYOXYSOMES and a large "centeral" vacuole which is present in animal cells but it is of small size and pushed towards periphery due to nucleus.
