Acceleration is the rate of change of velocity as a function of time. For example a car traveling at 50 km/hr starts to accelerate, 10 seconds after, its speed changes to 100 km/hr then the acceleration of the car during the time can be calculated as below: initial speed = 50 km/hr.
Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”
Upwelling occurs in the open ocean and along coastlines. The reverse process, called “downwelling,” also occurs when wind causes surface water to build up along a coastline and the surface water eventually sinks toward the bottom.
Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity. Therefore, good fishing grounds typically are found where upwelling is common.
Mechanical energy is the answer
Answer:
emf = 11.667 V
Explanation:
Given: charge q = 0.060 C, electric potential energy E =0.70 J,
Solution :
by definition 1 volt = 1 joule per coulomb
so Voltage = emf = E/C
emf = 0.70 J / 0.060 C
emf = 11.667 V
Answer:
radios work when electrons are speeding up and dow the attena, patters structure and shape make music pleasing to hear. (more info below)
Explanation:
a radio works when electrons are speeding up and down the antenna, sending out electromagnetic waves. Radiation waves travel through the air at the speed of light. When the radio waves reach the antenna, the electrons vibrate within the antenna and reproduce the initial signal. to make music pleasing to hear it has to have patterns, structure, shape.
hope this helped!
