Answer:

The giant-impact theory is actually the preferred or current scientific hypothesis accepted for the Moon's origin.

Explanation:

The giant-impact theory is actually the preferred or current scientific hypothesis accepted for the Moon's origin. This appears that Moon evolved out of residue left over after a collision between Earth and  Mars-sized celestial object around 4.5 billions year ago.

Sometimes the merging body is called Theia, named after the mythological Greek Titan that was Selene's mother, the Moon's goddess.

A 1-kg mass at the earth's surface weighs about? a. 1 n. b. 5 n. c. 10 n. d. 12 n. e. none of these

A 1-kg mass at the earth's surface weighs about C. 10N

The third planet from the Sun is the Earth. It is the seventh largest in terms of size and weighs roughly 5.98 1024 kg. The inherent quality of mass is unaffected by the environment of the object or the technique employed to quantify it.

Newton's law of gravitation can be used to estimate the mass of the Earth. This is set to the fundamental formula, which reads: force (F) = mass (m) times acceleration. Gravitational acceleration (G) is equal to 9.8 m/s2, the Earth's radius is 6.37 106 m, and the gravitational constant (G) is 6.673 1011 Nm2/kg2. The Earth has a mass of 5.96 1024 kg after rearranging the equation and entering all the numbers.

The Earth is constantly spinning on its axis, like you might spin a basketball on your finger. It is this spinning of the Earth
mash [69]

<u>Answer:</u>

The spinning of the earth around its own axis causes day and night.

<u>Explanation:</u>

Earth has two types of motions. It spins around its own axis causing day and night every 12 hours and completes a rotation in 23.93 hours that make a full day. The part of the earth that faces sunlight during spinning experiences day and the other part has night.  It also rotates around the sun and completes one rotation in 365 days that makes a year.

A 0.25 kg arrow with a velocity of 12 m/s to the west strikes and pierces the center of a 6.8 kg target. What is the final veloc
Mademuasel [1]

Answer:20/47 meter per second

Explanation:

Mass of arrow(ma)=0.25kg

Velocity of arrow(va)=12m/s

Mass of target(mt)=6.8kg

Velocity of target(vt)=0 since target is at rest

Conservation of linear momentum says that :

maxva+mtxvt=(ma+mt)V

V=(maxva+mtxvt)/(ma+mt)

V=(0.25x12+6.8x0)/(0.25+6.8)

V=3/(7.05)

V=20/47 meter per second
