The ball is traveling in the + x direction at 8m per second. After 20 seconds it has moved 160m forward from the spot where it was tossed.
Answer:
Therefore,
The resistor value , R is 9.4 kΩ.
Explanation:
Given:
A neon gas tube has
Von = 60.0 V and
Voff = 30.0 V
Capacitor, C = 20.0 μF
Battery , E = 120 V
Frequency = f = 30 hz
To Find:
Resistor , R =?
Solution:
Time period of the wave will be only the charging time of the capacitor,the capacitor will be charged to Von from initial voltage Voff is given by,
Where,
R = Resistance
C =Capacitance
E = Battery in volts
ln = natural Log (Sign)
Substituting the values we get
Therefore,
The resistor value , R is 9.4 kΩ.
When two things in contact with each other transfer heat - Conduction
When a liquid or has carries heat- Convection
When waves transfer heat- Radiation
Answer:
Slope in Mathematics means the inclination of a line
To solve this problem it is necessary to apply the concepts related to work and power.
Remember that work is defined as the force applied on a body - or exerted by it - to travel a certain distance, and that the power is that energy mentioned to perform that activity in a given instance of time.
Mathematically work is defined as
Where
d = Distance
At this case the acceleration is the same that gravitational acceleration
At the same time we have that power is defined as
Replacing our values we have that the Work done was
Now substituting this value at the Power equation we have
Therefore the power that she is supplying is 100W.
