Which term refers to the rate of change of motion?

Physics
1 answer:
borishaifa [10]3 years ago
4 0

Answer:

The term that refers the rate change of motion is acceleration.

Explanation:

The rate at which the motion changes is called as the acceleration. It is a vector quantity with the SI unit meters. There is device to measure the acceleration called as accelerometer. The acceleration is also affected by the increase and the decrease of the force and mass. It is directly proportional to it. The acceleration increases with force, but found to be decreasing with mass. It can be calculated by taking the product of displacement by time.

If one oscillation has 5. 8 times the energy of a second one of equal frequency and mass, what is the ratio of their amplitudes?
quester [9]

The ratio of their amplitudes will be 2.41.

To find the answer, we have to know more about the simple harmonic motion.

<h3>How to find the ratio of their amplitudes?</h3>
  • It is given that,

                        E_1=5.8E_2\\m_1=m_2 \\\omega_1=\omega_2

  • We have the relation between these quantities and amplitudes as,

                        A=\sqrt\frac{2E}{k} \\k=m\omega^2

  • Here, for both the oscillation, k will be same.
  • Thus, the ratio of amplitude will be,

                      \frac{A_1}{A_2} =\sqrt{\frac{E_1}{E_2} } =\sqrt{\frac{5.8E_2}{E_2} } =2.41

Thus, we can conclude that, the ratio of their amplitudes will be 2.41.

Calculate the pressure of water in a well if the depth of the water is 10m​
Kryger [21]

Answer:

P= phg

so:- the height is 10m

density of water 1000 kg/m3

gravity is 9.8m/s2

P=1000 kg/m3*10m*9.8m/s2

=98000Pa

=98KPa

A 56.0 kg bungee jumper jumps off a bridge and undergoes simple harmonic motion. If the period of oscillation is 11.2 s, what is
andre [41]

Answer:

2.80N/m

Explanation:

Given data

mass m= 56kg

perios T= 11.2s

The expression for the period is given as

T=2π√m/k

Substitute

11.2= 2*3.142*√56/k

square both sides

11.2^2= 2*3.142*56/k

125.44= 351.904/k

k=351.904/125.44

k= 2.80N/m

Hence the spring constant is 2.80N/m

To provide the pulse of energy needed for an intense bass, some car stereo systems add capacitors. One system uses a 2.4F capaci
Natasha_Volkova [10]

Answer:

Explanation:

Energy stored in a capacitor

= 1/2 CV²

C is capacitance and V is potential of the capacitor .

When capacitor is charged to 24 V ,

E₁ = 1/2 x 2.4 x 24 x24 = 691.2 J

When it is charged to 12 volt

E₂ = 1/2 CV²

.5 X 2.4 X 12 X12

= 172.8 J
