Write a use of magnetic force and frictional force each​

Physics
1 answer:
Firdavs [7]3 years ago
7 0
Magnetic force:Computer hard drives use magnetism to store the data on a rotating disk. More complex applications include: televisions, radios, microwave ovens, telephone systems, and computers. ... Frictional force:Quite often uses of friction can be seen from how things would be without friction.

2. Un ciclista que está en reposo comienza a pedalear hasta alcanzar los 16.6km/h en 6 minutos. Calcular la distancia total que
jek_recluse [69]

Answer:

s = 5822.28\,m\,(5.822\,km)

Explanation:

La distancia recorrida es la suma de las etapas de aceleración y velocidad constante (Travelled distance is the sum of the acceleration and constant speed stages). La aceleración es (The acceleration is):

a = \frac{4.611\,\frac{m}{s}-0\,\frac{m}{s}}{360\,s}

a = 0.013\,\frac{m}{s^{2}}

La distancia recorrida es (The travelled distance is):

s = \frac{1}{2}\cdot \left(0.013\,\frac{m}{s^{2}} \right)\cdot (360\,s)^{2} + \left(4.611\,\frac{m}{s} \right)\cdot (1080\,s)

s = 5822.28\,m\,(5.822\,km)

What weather condition creates a tornado?
AnnZ [28]

Answer:

Tornadoes form in unusually violent thunderstorms when there is sufficient (1) instability and (2) wind shear present in the lower atmosphere. Instability refers to unusually warm and humid conditions in the lower atmosphere, and possibly cooler than usual conditions in the upper atmosphere.

Why is it important to use the correct number of significant digits when
Pani-rosa [81]

A. To show how precise your measurements were

Explanation:

It is important to use the correct number of significant digits when reporting the results of an experiment because they show how precise measurement are.

  • Precision is the ability to reproduce a particular set of results in an experiment.
  • Every instrument have their precision level.
  • The precision levels shows to what extent the values obtained can be trusted..
  • Significant figures are not only important in recording measurements, they are also needed for calculations in science.

The mass of a hypothetical planet is 1/100 that of Earth and its radius is 1/4 that of Earth. If a person weighs 600 N on Earth,
omeli [17]

To solve this problem we will apply the Newtonian concept of gravitational acceleration produced by a planet. This relationship is given by:

g = \frac{GM}{r^2}

Where,

G = Gravitational Universal Constant

M = Mass of Earth

r = Radius

The values given are based on the constants of the earth, so they can be expressed as

M_p = \frac{1}{100} M_e

r_p = \frac{1}{4} r_e

The relationship of gravity would then be given:

g_e = \frac{GM_e}{r_e^2}

The relationship with the new planet, from the gravity of the earth would be given

g_p = \frac{GM_p}{r_p^2}

g_p = \frac{G(1/100)M_e}{(1/4 r_e)^2}

g_p = \frac{GM_e 16}{100 r_e^2}

g_p = 0.16 \frac{GM_e}{r_e^2}

g_p = 0.16g_e

The relationship with the weight of the earth would be given as:

W_e = m*g_e = 600N

W_p = m*g_p = m(0.16g_p)

W_p = (m*g_p)(0.16)

W_p = 600*0.16

W_p = 96N

Therefore the weigh on this planet would be 96N
