The correct answers are <span>starting friction and </span>static friction
Friction slows down all forces, but starting friction slows down or stops completely the start of motion.
Answer:
The new length is 50.00885m
Explanation:
linear thermal expansion coefficient Fe 11.8e-6 /K
The new length can be determined using the following equation:
∆L/L = α∆T, where α is linear thermal expansion coefficient
∆L = Lα∆T = 50(11.8e-6)(35-20) = 0.00885 m
New length = ( 50.000 + 0.00885)m =
New length = 50.00885 m
Answer:
The Moon revolves or moves around the Earth in a path called its orbit and rotates, or spins, in space.
Explanation: The Moon's movements cause the phases of the Moon and the Earth's ocean tides.
Answer:
1 mile
Explanation:
We can use the following equation of motion to solve for this problem:
where v m/s is the final take-off velocity of the airplane, 
initial velocity of the can when it starts from rest, a is the acceleration of the airplanes, which are the same, and 
is the distance traveled before takeoff, which is minimum runway length:
From here we can calculate the distance ratio
Since the 2nd airplane has the same acceleration but twice the velocity
So the minimum runway length is 1 mile
The answer is D, Carbon and hydrogen
