Objects of equal mass are oscillating up and down in simple harmonic motion on two different vertical springs. The spring consta

olga55 [171]

Answer:1080 N/m

Explanation:

Given

Spring constant of first Spring $K_1=245 N/m$

mass of both the system is same

Both system have same maximum velocity

if $x=A\sin \omega t$ is general equation of SHM

then maximum velocity is given by

$v_{max}=A\omega$

$\omega =\sqrt{\frac{k}{m}}$

$v_1_{max}=A_1\omega _1$

$\omega _1=\sqrt{\frac{k_1}{m}}$

similarly $\omega _2=\sqrt{\frac{k_2}{m}}$

also $A_1=2A_2$

so $A_1\times \sqrt{\frac{k_1}{m}}=A_2\times \sqrt{\frac{k_2}{m}}$

$2\times \sqrt{k_1}=\sqrt{k_2}$

$k_2=4k_1$

$k_2=4\times 245=1080 N/m$

List and define all of Newton’s laws of motion.

Luba_88 [7]

Answer:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Consider the f(x) = Acos(x) function shown in the figure in blue color. What is the value of amplitude A for this function?

Alex73 [517]

The amplitude of the red colored wave is 1 unit and the amplitude of the red colored wave is 2.1 unit.

<h3>What is amplitude of a wave?</h3>

The amplitude of a wave is the maximum displacement of the wave. It can also be described at the maximum upward displacement of a wave curve.

<h3>Amplitude of the red colored wave</h3>

From the graph, the amplitude of the red colored wave is 1 unit.

<h3>Amplitude of the blue colored wave</h3>

From the graph, the amplitude of the red colored wave is 2.1 unit.

Thus, the amplitude of the red colored wave is 1 unit and the amplitude of the red colored wave is 2.1 unit.

An ion with charge of Q = +3.2 x 10-19 C is in a region where a uniform electric field of magnitude E = 5.0 X 105 V/m is perpend

san4es73 [151]

Answer:

option C

Explanation:

given,

Q = +3.2 x 10⁻¹⁹ C

E = 5.0 X 10⁵ V/m

B = 0.80 T

ion's acceleration is zero

when acceleration is zero the magnitude of both the forces becomes equal.

q E = q V B

v = $\dfrac{E}{B}$

v= $\dfrac{5 \times 10^5}{0.80}$

v = 6.25 × 10⁵ m/s ≈ 6.3 × 10⁵ m/s

hence, the correct answer is option C
