Answer:5m
Explanation:a=-10m/s (since it moved upwards against gravity)
V=0
U=10m/s
v2=u2+2as
0= 100-20s
20s=100
s=5m
False. You don’t want to over work yourself :) start at a level you are comfortable with and continue with making it more and more harder. EX: you can run around your block and you feel tired but refreshed. Do it everyday until you feel like you can go further
Answer:
The magnitude of the resultant is approximately 5.391 units.
Explanation:
We notice that vectors have the following characteristics: A magnitude and direction. That is:
Where:
- Magnitude, dimensionless.
- Direction, measured in radians.
This expression can be rearranged as:
Where:
If we know a set of vectors of the form , the resultant vector () is the vectorial sum of every vector in the set:
If we know that , , and , the resultant vector is:
And lastly, we obtain the magnitude of the resultant by Pythagoras' Theorem:
The magnitude of the resultant is approximately 5.391 units.
Answer:
4 m/s
Explanation:
T = Tension
m = Mass of string
Velocity of wave in string is given by
For first cable
For second cable
The speed of wave in cable two is 4 m/s
Answer:
0.054 A
Explanation:
We have given inductance
Capacitance
Charge
The energy stored in the LC circuit is given by
So energy
This energy is also equal to
So
i=0.054 A
So maximum current will be 0.054 A
