A car accelerates from rest to 27 m/s in 8 seconds. What is the acceleration of the car?

Vlad1618 [11]

Answer:

<h3>The answer is 3.38 m/s²</h3>

Explanation:

The acceleration of an object given it's velocity and time taken can be found by using the formula

$a = \frac{v}{t} \\$

where

a is the acceleration

v is the velocity

t is the time

From the question

v = 27 m/s

t = 8 s

We have

$a = \frac{27}{8} \\ = 3.375$

We have the final answer as

Hope this helps you

For small amplitudes of oscillation the motion of a pendulum is simple harmonic. Consider a pendulum with a period of 0.550 s Fi

Ivenika [448]

To solve this problem we will use the concepts related to the expression of energy for harmonic oscillator. From our given values we have that the period is equivalent to

$T = 0.55s$

Therefore the frequency will be the inverse of the period and would be given as

$f= \frac{1}{T}$

$f = \frac{1}{0.55}$

$f = 1.82s^{-1}$

The ground state energy of the pendulum is,

$E = \frac{1}{2} hv$

$E = \frac{1}{2}(6.626*10^{-34}J\cdot s)(1.82s^{-1})$

$E = 6.03*10^{-34}J$

The ground state energy in eV,

$E = 6.03 * 10^{-34}J(\frac{1eV}{1.6*10^{-19}J})$

$E = 3.8*10^{-15}eV$

The energy difference between adjacent energy levels,

$\Delta E = hv$

$\Delta E = (6.626*10^{-34}J\cdot s)(1.82s)$

$\Delta E = 12.1*10^{-34}J$

Explain the relationship between electrical charge and force.

Radda [10]

The relationship between electrical and charge force is that electrical force strengthens and increases the energy pulses and reflects off an object and makes the force about two times greater with charge.
