Recently, the media, always trying to make things sound sensational, have started to call totally eclipsed moon "the blood moon.

" Why does the Moon look reddish to us when there is a total lunar eclipse?

Answer:

See explanation

Explanation:

- One meaning of a "blood moon" is based on its red glow. This blood moon occurs during a total lunar eclipse. During a total lunar eclipse, Earth lines up between the Moon and the Sun. This hides the Moon from the sunlight.

- When this happens, the only light that reaches the Moon's surface is from the edges of the Earth's atmosphere. The air molecules from Earth's atmosphere scatter out most of the blue light. The remaining light reflects onto the Moon's surface with a red glow, making the Moon appear red in the night sky.

If a displacement vector has a negative x component and a positive y component,
bezimeni [28]

Answer:

The direction will be NE i.e North east.

Explanation:

From the question, it will be travelling in North east direction because the the negative X components in vector is in horizontal direction which is the Eastern direction when using the four cardinal points and the Y components, the positive is in North direction if you use the four cardinal points. Therefore, the vector with both X components and Y components will be travelling in Northeast direction.

2. Why do some clouds rain while others do not?
andreyandreev [35.5K]

Some clouds do not rain and others do because the clouds that do not rain do not have enough water in them. White clouds are ones that do not have enough water in them.

A block rides on a piston that is moving vertically with simple harmonic motion. (a) If the SHM has period 2.68 s, at what ampli
fredd [130]

Answer:

Part a)

A = 1.78 m

Part b)

f = 2 rev/s

Explanation:

Part A)

As we know that time period of the motion is given as

T = 2.68 s

so we have

\omega = \frac{2\pi}{T}

\omega = \frac{2\pi}{2.68}

\omega = 2.34 rad/s

now at the point of maximum amplitude the force equation when Normal force is about to zero is given as

mg = m\omega^2 A

so we have

A = \frac{g}{\omega^2}

A = \frac{9.81}{2.34^2}

A = 1.78 m

Part b)

Now if the amplitude of the SHM is 6.23 cm

and now at this amplitude if object will lose the contact then in that case again we have

mg = m\omega^2 A

g = \omega^2 (0.0623)

\omega = 12.5 rad/s

so now we have

2\pi f = 12.5

f = 2 rev/s

Two people push on a boulder to try to move it. The mass of the boulder is 815 kg. One person pushes north with a force of 65 N.
ivanzaharov [21]

Answer:

0.095 m/s^2

Explanation:

As the 2 force directions are perpendicular (North vs West), we can calculate the magnitude of the net force using the following equation

F = \sqrt{65^2 + 42^2} = 77.4 N

Assuming negligible friction, from here we can calculate the acceleration in accordance to Newton's 2nd law of motion

a = F/m = 77.4 / 815 = 0.095 m/s^2

A bus is moving at a constant speed of 40 m/s. How many hours will it takes to travel 260 miles?
lawyer [7]

Explanation:

1 mile = 1609m

Distance=260 miles= 418340 m

Speed= 40 m/s

Time = distance/speed

= 418340/40

=10458.5 seconds

= 2.9 hours
