How do lines of latitude affect how direct or indirect the Sun’s rays are on the Earth?

Physics

Sonja [21]4 years ago

Answer:

Explanation:  We have seasons because Earth's axis – the imaginary line that goes through the Earth and around which the Earth spins — is tilted. It's tilted about 23.5 degrees relative to our plane of orbit (the ecliptic) around the Sun. As we orbit our Sun, our axis always points to the same fixed location in space. Our northern axis points almost directly toward Polaris, the North Star.

Meteoroids are small objects in space, usually made of rock or metal. These bodies often get close to a planet and fall through
ser-zykov [4K]

Answer:

1. A burning streak of light, called a Meteor.

2.The rocky bodies that survives the fall to the planet’s surface are Meteorites.

Explanation:

Let us see the difference between them.  

  1. Asteroids: They are the remnants of a broken planet orbiting the sun in between Mars and Saturn.  They are small rocky bodies from a tennis ball size to larger ones weighing a few tones.
  2. Meteoroids: They are the small rocky objects of pebble size formed due to the collision of asteroids.
  3. Meteors: These are pebble size objects that enter Earth's atmosphere and burns off by forming streaks of light.
  4. Meteorites: These are rocky objects bigger than meteors than don't burn out completely and fall on the earth's surface.
  5. Comets:  These are objects mainly made of dust and ice that orbit the sun in a highly elliptical orbit. This composition makes a long tail when approaching the sun.

- How long does it take a packet of length 1,000 bytes to propagate over a link of distance 2,500 km, propagation speed 2.5 *10^
Sunny_sXe [5.5K]

Answer:

It will take 0.01 s or 10 ms

Solution:

As per the question:

Length of the packet, L = 1,000 bytes = 1000\times 8 = 8000 bits

Distance, d = 2500 km = 2.5\times 10^{6}\ m

Speed of propagation, s = 2.5\times 10^{8}\ m/s

Transmission rate, R = 2 Mbps

Now,

Propagation time, t can be calculated as:

t = \frac{d}{s} = \frac{2.5\times 10^{6}}{2.5\times 10^{8}} = 0.01\ s

t = 10 ms

  • In general, propagation time, t is given by:

       t = \frac{link\ distance}{Propagation\ speed}

  • No, this delay is independent of the length of the packet.
  • No, this delay is independent of the rate of transmission.

A thin hoop is supported in a vertical plane by a nail. What should the radius of the hoop be in order for it to have a period o
maxonik [38]

Answer:

0.124 m

Explanation:

the period of a simple pendulum with a small amplitude is given as

T = 2π [√(I/mgd)]

From the above stated formula,

I = moment of inertia

m = mass of the pendulum

g = acceleration due to gravity, 9.8 m/s²

d = distance from rotation axis due to center of gravity

Also, moment of Inertia, I = 2mr², if we substitute this in the above formula, we have

T = 2π [√(2mr²/mgd)]

If we assume that our r = d, then we have

T = 2π [√(2r/g)]

If we make r the subject of the formula in the above equation, we get

r = gT² / 8π²

r = (9.8 * 1²) / 8 * π²

r = 9.8 / 78.98

r = 0.124 m

Thus, the radius of the hoop is 0.124 m
