The answer is V=25(7.5/(7.5+5)).
This is the voltage divider equation.
I hope this helps!
Answer:
K = 316.66 N/m
Explanation:
Given that
F= 19 N
Displacement .x= 0.06 m
We know that spring force F given as
![F=k x](https://tex.z-dn.net/?f=F%3Dk%20x)
F = force
K = Spring constant
x = Displacement
Now by putting the values in the above equation
![19 = 0.06\times K](https://tex.z-dn.net/?f=19%20%3D%200.06%5Ctimes%20K)
![K=\dfrac{19}{0.06}](https://tex.z-dn.net/?f=K%3D%5Cdfrac%7B19%7D%7B0.06%7D)
K = 316.66 N/m
Therefore the value of spring constant will be 316.66 N/m.
Answer:
m = 47.5 Kg
Explanation:
given,
speed of skater toward north, v = 0.8 m/s
momentum of the skater in north, P = 38 Kg.m/s
mass of the skater = ?
we now,
Momentum is equal to the product of mass and velocity
P = m x v
38 = m x 0.8
![m = \dfrac{38}{0.8}](https://tex.z-dn.net/?f=m%20%3D%20%5Cdfrac%7B38%7D%7B0.8%7D)
m = 47.5 Kg
hence, mass of the skater is equal to 47.5 Kg.
They are similar because they are all colors in the spectrum and they are different because you cant seperate primary colors but you can seperate secondary
No they don't. Without air resistance, objects fall with constant
acceleration.
On Earth, the acceleration is 9.8 m/s² ... the speed of a falling object
at any time is 9.8 m/s faster than it was 1 second earlier.
