Answer:
Explanation:
decrease in energy of the transferred charge
= Voltage x charge
= 2.86 x 10⁹ x 23.1
= 66.067 x 10⁹ J
the final speed of the automobile be V
1/2 m v² = 66.067 x 10⁹
v² = 66.067 x 10⁹ x 2 / 1519
= .08698 x10⁹
= 87 x 10⁶
v = 9.32 x 10³ m / s
Answer:
Opposite direction
Explanation:
For example: The first object travels in the direction pointing to east, while the other one travels pointing to the west.
The first object will have a positive value while the second one will have a negative, cause it's going to the opposite direction
Answer:
Mass of banana is
Kg
Explanation:
Step 1: Determine the equation of speed of an object moving in an harmonic motion
Speed of moving in an harmonic motion is given by

Here, v represents the speed of the object in harmonic motion, k is the springs constant, m is the mass of the object, A is the amplitude, and x is the position.
In this question ,
because only at this position maximum speed occurs
So the simplified equation becomes -

OR

Substituting the given values in above equation we get -
Assume spring constant is
N/m

Mass of banana is
Kg
Answer:
Wavelength!
Explanation:
At least I think? Or wavelength might be crest to crest! Sorry if I'm incorrect. Let me know how I did!
