Andre listed some properties of electromagnetic waves.
ANEK [815]

Answer: Electromagnetic waves can transfer energy through empty space.

Explanation:

Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. The electric field and magnetic field of an electromagnetic wave are perpendicular to each other. They are also perpendicular to the direction of the wave.

Electromagnetic waves travel with speed of light in vacuum.

Electromagnetic wave does not need a medium to propagate or travel from one place to another. Electromagnetic waves are 'transverse' waves which means that they are measured by their amplitude and wavelength.

Electromagnetic waves do not lose energy when they travel and thus can travel far from its source.

how long would it take a 3.4 kg bike with 79 kg rider traveling at 18.6 m/s to stop if 867 N of force is applied to the brakes?
nalin [4]

Answer: 1.76 s

Explanation:

We have the following data:

m=3.4 kg+79 kg=82.4 kg is the total mass of the bike and the rider

V_{o}=18.6 m/s is the initial velocity

F=867 N is the force applied to the brakes

Firstly, we will find the acceleration a with the following equation:

F=m.a (1)

Isolating a:

a=\frac{F}{m} (2)

a=\frac{867 N}{82.4 kg} (3)

a=10.52 m/s^{2} (4) This is the magnitude of the acceleration, however, since the final velocity is 0 m/s, this means the direction is negative

Hence:

a=-10.52 m/s^{2} (5)

On the other hand, with the following equation we can find the time t:

V=V_{o}+at (6)

Where:

V=0 m/s is the final velocity (the bike stops)

Isolating t:

t=-\frac{V_{o}}{a} (7)

t=-\frac{18.6 m/s}{-10.52 m/s^{2}} (8)

Finally:

t=1.76 s This iste time it takes to the bike to stop
