Answer:
Increases is the correct answer.
Explanation:
Just took the quiz.
Answer:
The skater 1 and skater 2 have a final speed of 2.02m/s and 2.63m/s respectively.
Explanation:
To solve the problem it is necessary to go back to the theory of conservation of momentum, specifically in relation to the collision of bodies. In this case both have different addresses, consideration that will be understood later.
By definition it is known that the conservation of the moment is given by:
Our values are given by,
As the skater 1 run in x direction, there is not component in Y direction. Then,
Skate 1:
Skate 2:
Then, if we applying the formula in X direction:
m_1v_{x1}+m_2v_{x2}=(m_1+m_2)v_{fx}
75*5.45-75*1.41=(75+75)v_{fx}
Re-arrange and solving for v_{fx}
v_{fx}=\frac{4.04}{2}
v_{fx}=2.02m/s
Now applying the formula in Y direction:
Therefore the skater 1 and skater 2 have a final speed of 2.02m/s and 2.63m/s respectively.
Ultraviolet, visible, infrared, and radio waves are passing the atmosphere. O<span>ur atmosphere blocks most ultraviolet light (UV) and all X-rays and gamma-rays from reaching the surface of Earth. With this in mind B: is your only answer.</span>
Answer:
The current doubles
Explanation:
In a circuit, Ohm's law gives the relationship between voltage, current and resistance:
where
V is the voltage
R is the resistance
I is the current
In this problem,
V is held constant
R is halved:
Therefore, the new current is
So, the current doubles.
