Answer:
Explanation:
We first identify the elements of this simple harmonic motion:
The amplitude A is 8.8cm, because it's the maximum distance the mass can go away from the equilibrium point. In meters, it is equivalent to 0.088m.
The angular frequency ω can be calculated with the formula:
Where k is the spring constant and m is the mass of the particle.
Now, since the spring starts stretched at its maximum, the appropriate function to use is the positive cosine in the equation of simple harmonic motion:
Finally, the equation of the motion of the system is:
or
The temperature rises during boiling.
Sound travels 1,480 meters per second, which is about 4.3 times as fast as air. Sound travels much slowly in air. This has to do with the frequency, intensity and amplitude of waves, which are affected differently in water and air.
Answer:
(a) 5.056 x 10^-14 N
(b) 5.056 x 10^-14 N
Explanation:
X component of velocity of electron is 1.6 × 10^6 m/s
Y component of velocity of electron is 2.4 × 10^6 m/s
X component of magnetic field is 0.025 T
Y component of magnetic field is -0.16 T
charge on electron, q = - 1.6 x 10^-19 C
Write the velocity and magnetic field in the vector forms.
The force on the charge particle when it is moving in the magnetic field is given by
(a) Force on electron is given by
Magnitude of force is 5.056 x 10^-14 N.
(b) Force on a proton is given by
Magnitude of force is 5.056 x 10^-14 N.
Thus, the magnitude of force remains same but the direction of force is opposite to each other.
Explanation:
Answer:
x = 54.15 meters between the balloons horizontally.
Explanation:
Hence, vertical distance between balloons is 12.8 meters.
y= 61-48.2 = 12.2 m
A right-angle triangle is formed with,
angle θ = 13.3 degrees
opposite (y) = 12.8
adjacent (x) = ?
Now by putting the values in the above equation.
x = 54.15 meters between the balloons horizontally.
