Frequency is not a length of time. It's exactly the opposite.
Frequency tells you how often something happens. In fact,
the unit 'Hz' means 'per second'.
Frequency of 2 Hz means "It happens at 2 per second."
The time it takes for the thing to happen once is exactly the
'reciprocal' of the frequency ... ' 1 ' divided by the frequency.
If the frequency is 2 Hz, then the thing happens every 1/2 second.
If the frequency is 74 Hz, then it happens every 1/74 of a second.
If the frequency is 1 KiloHz, then it happens every 1/1000 second.
Arrow at the left side pointing towards right side represents the frictional force as it always acts opposite to motion
Answer:
Yes
Explanation:
Newton's laws states that gravity or force will stop the balls movement. Think of space for a example, if you pushed a soccer ball into space if would float for eternity.
Answer: symphathetic, parasymphatetic
Explanation:
The accelerated heartbeat has a opposite action as compared to the slowed heartbeat likewise the symphathetic nervous system has a opposite action that of parasymphatetic system.
The symphathetic nervous system helps the body to perform intense physical activity like in case of fight or flight response. The parasympathetic nervous system relaxes the body and inhibits its functions that require energy.
Answer:
48m
Explanation:
- Initial velocity = 4m/s
- Acceleration = 4m/s²
- Time = 4s
- Displacement = ?
From Second equation of motion ,
s = ut + 1/2at²
s = 4*4 + 1/2*4*(4)² m
s = (16 + 2 * 16) m
s = ( 16 + 32 )m
s = 48 m
