Answer:

Elastic potential energy

Elastic potential energy is stored in the spring. Provided inelastic deformation has not happened, the work done is equal to the elastic potential energy stored.

An eastbound car travels a displacement of 80.0 Km in 45 minutes. What is the velocity
alexgriva [62]

Explanation:

d= 80km = 8000m

t = 45 min = 45/60 h

= 0.75 h

V= ?

we know that,

V = d /t

or,V= 80 km / 0.75 h

  1. or, V= 106.67 km/hr

or,V= 106.67×1000m / 3600 s

2. or, V= 29.63 m/s

Electromagnetic radiation consists of discrete packets of kinetic energy called ______, which are characterized by a certain wav
aleksandr82 [10.1K]

Electromagnetic radiation consists of discrete packets of kinetic energy called Photons, which are characterized by a certain wavelength and energy level.

<h3>What are photons? </h3>

The representation by a particle of a quantum of light or any other electromagnetic radiation is called photons. The energy is proportional to the frequency of radiation however it has zero mass. It travels at a constant speed. It is a carrier of energy. When the sun changes the particles into both light and heat, it is a photon. They don’t carry any electrical charge. They are like electric fields traveling through space as shown by Maxwell in his theory.  They can be easily created and destroyed. They are also called light quantum.

A uniform rod is set up so that it can rotate about an axis at perpendicular to one of its ends. The length and mass of the rod
guapka [62]

Answer:

F = 0.179 N

Explanation:

given,

length of the rod = 0.759 m

mass of the rod = 1.03 kg

force = ?

initial angular speed = 0 rad/s

final angular speed = 6.87 rad/s

time interval = 9.95 s

the angular acceleration

\alpha = \dfrac{\omega_f-\omega_i}{\Delta t}

\alpha = \dfrac{6.87 -0}{9.95}

\alpha =0.690\ rad/s^2

moment inertial of the rod

I =\dfrac{mL^2}{3}

torque produced by the rod τ = I α

torque is also equal to τ = F L

now,

F L =  I α

F L=(\dfrac{mL^2}{3})\times \alpha

F= (\dfrac{1.03\times 0.759}{3})\times 0.690

F = 0.179 N
