Answer:
Explanation:
mass of first marble 
Initial velocity of the first marble 
considering right side as positive
Mass of second marble
After collision first marble moves to the left with a velocity of 18 cm/s
i.e. 
considering 
be the velocity of second marble after collision
The Coefficient of restitution is 1 for an elastic collision
Putting values
So, the velocity of the second marble is 22.5 m/s to the right after the collision
(b)Initial kinetic energy =
Final kinetic energy=
Answer:
false
Explanation: all compounds are electrically neutral.
Heya!!
For calculate wavelength, lets applicate formula:
<u>Δ Being Δ</u>
f = Frequency = 262 Hz
v = Velocity = 343 m/s
= Wavelenght = ?
⇒ Let's replace according the formula:
⇒ Resolving
Result:
The wavelength is <u>1,3 meters.</u>
Good Luck!!
Answer:
No. It may be at rest or moves with a constant velocity.
Explanation:
The term "net force" refers to the vector addition of all forces acting on a defined body.
If the magnitude of the net is zero, then the acceleration of the given body would be zero. Hence, the given body may be moving with an unchanged velocity or at rest.
Positive
In an LED, the longer lead is always connected to the positive terminal
