1 nanowatt = 1 nanojoule/sec
1 watt = 1 joule/sec
10 watts = 10 joules/sec
100 watts = 100 joules/sec
742.914 watts = 742.914 joules/sec
1,000 watts = 1,000 joules/sec
10,000 watts = 10,000 joules/sec
100,000 watts = 100,000 joules/sec
1 megawatt = 1 megajoule/sec
1 gigawatt = 1 gigajoule/sec
1 petawatt = 1 petajoule/sec
We don't care what frequency the transmission is using,
or who their morning DJ is.
Explanation:
It's displacement would be negative
displacement is a vector quantity.
'Backwards', we can assume, would be negative.
and forwards, positive. So going backwards would mean a negative displacement.
Well you know the formula is,
Power= Work/Time
So as time increases, Power Decreases, it's an inverse relationship.
Think about it like this, to have more "power" you have to be able to do a lot in a short amount of time, so by spending more time on something, your power decreases.
Answer:
Explanation:
Let l be th length of pendulum
loss of height
= mg ( l - l cos50)
= mg l ( 1-cos50)
1/2 mv² = mgl ( 1-cos50)
v = √[2gl( 1- cos50)]
= √( 2 x 9.8 x .7 x ( 1-cos50)
= 2.2 m / s
speed at the bottom = 2.2 m /s
b )
centripetal acceleration
= v² / r
= 2.2 x 2.2 / .7
= 6.9 m /s²
C )
If T be the tension
T - mg = mv² / r
T = mg + mv² / r
= .13 X 9.8 + .13 X 6.9
= 2.17 N
