Sunlight and wind because they never run out
Answer:
Part a)
Part b)
Part c)
As per Newton's III law force due to trailer on the car is same as that of force due to car on trailer.
Explanation:
As we know that
mass of car = 1120 kg
mass of trailer = 290 kg
acceleration of both
Part a)
Net force on the car
Part b)
Net force on the trailer is given as
Part c)
Force applied by car on the trailer is given as
so as per Newton's III law force due to trailer on the car is same as that of force due to car on trailer.
Answer:
7?
Explanation:
Waves – disturbances caused by the movement of energy from a source through some medium. Floating Gull- Figure 10.1 – water is not moving – only the energy is moving through the water. Transfer of energy from water particle to water particle – circular path, an orbit Orbital waves – a wave in which particles of the medium (water) move in closed circles as the wave passes. ¾ These types of waves occur between fluids of different densities as well as between air/water. These waves are Progressive Waves – move forward through their medium. Parts of the wave: Wave Crest: highest Part of the wave Wave Trough: valley between wave crests Wave Period: time it takes for a wave to move a distance of one wave length. Wave Length: horizontal distance between two successive crests (or troughs) Wave Frequency: the number of waves that pass a fixed point per second Motion of the wave is negligible after ½ wavelength in depth Figure 10.3 indicates that water molecules in the crest of a passing wave move in the same direction as the wave, but molecules in the trough move in the opposite direction.
