The answer is A) frequency
The amplitude of Wave 2 is greater than Wave 1's, as is the wavelength. You can see that Wave 2 has a higher period and greater peaks and troughs than Wave 1.
You can also see that Wave 2 has half the frequency, meaning Wave 1 completes 2 periods for every 1 period that Wave 2 completes.
The total momentum before and after the collision must be conserved.
The total momentum before the collision is:
where m1 and m2 are the masses of the two players, and
and
their initial velocities. Both are considered with positive sign, because the two players are running toward the same direction.
The final momentum is instead
because now the two players are moving together with a total mass of (m1+m2) and final speed vf.
By requiring that the momentum is conserved
we can calculate vf, the post-collision speed:
and the direction is the same as the direction of the players before the collision.
Answer:
215.6Nm
Explanation:
The figure below shows a 10-kg mass hung from the end of a rod that is 2.2 m in length. Find the magnitude of the torque produced by the hung mass (m)
Torque = Force × radius
Torque = mg × radius
Torque = 10(9.8) × 2.2
Torque = 98 × 2.2
Torque = 215.6Nm
Answer:
directly
Explanation:
In linear circuits, voltage and current are directly related. In nonlinear circuits, the relationship depends on the nonlinearity. We generally study linear circuits.
