Answer:
At its most natural frequency. ... A forceful voice, exquisite control of frequency, and oscillating
If a conductor wire is heated, its resistance decreases and conductivity increases.
Answer:
Furthermore, the Pythagorean theorem works when the two added vectors are at right angles to one another - such as for adding a north vector and an east vector.
Answer: lift force = 100sin60 = 86.6 N
pull force = 100sin60 = 50.0 N
Explanation:
Answer:
V=14.9 m/s
Explanation:
In order to solve this problem, we are going to use the formulas of parabolic motion.
The velocity X-component of the ball is given by:

The motion on the X axis is a constant velocity motion so:

The whole trajectory of the ball takes 1.48 seconds
We know that:

Knowing the X and Y components of the velocity, we can calculate its magnitude by:
