Answer:
The distance which the car skid is 
Explanation:
From the question we are told that
The initial velocity of the car is 
The coefficient of kinetic friction is 
According to the law of energy conservation
The initial Mechanical Energy = The final Mechanical Energy
The initial mechanical energy is mathematically represented as
where KE is the initial kinetic energy which is mathematically represented as
And PE is the initial potential energy which is zero given that the car is on the ground
Now
Where 
is the work which friction exerted on the car which is mathematically represented as
Where 
is the distance covered by the car before it slowed down
=>
B. They came up with the term “radioactivity.”
C. They conducted experiments with uranium-containing minerals and pure uranium.
E. They discovered two new radioactive elements
I believe the answer would be 446.9 J.
Answer:
It's due to the distance from either ends of strings origin...
Explanation:
As we know that waves behave moving in a flow from one side to another side and this gives a prospective of motion. Suppose a wave is pinched from the near one end of a guitar then due to the distortion created by the point of tie of strings the wave super imposes and moves with a velocity v and produces a wave frequency f. as we the pinching go down to the center the wave stabilizes itself to a stationary origin right at the center and the frequency then changes accordingly as moving down on the string.
Answer:
Horizontal distance is 1.28 + 2.04 = 3.32 m
Explanation:
Given data:
from below figure
Applying Pythagoras theorem
from Snell's law
solving for x we have
x = 1.28
Horizontal distance is 1.28 + 2.04 = 3.32 m
