ORIGIN OF MOON AND THE RELATIONSHIP WITH THE EARTH
ziro4ka [17]

The moon's gravity pulls at the Earth, causing predictable rises and falls in sea levels known as tides. To a much smaller extent, tides also occur in lakes, the atmosphere, and within Earth's crust.

A NASA explorer spacecraft with a mass of 1,000 kg takes off in a positive direction from a stationary asteroid. If the velocity
Jet001 [13]

Before the launch, the momentum of the (spacecraft + asteroid) was zero.  So after the launch, the momentum of the (spacecraft + asteroid) has to be zero.

Momentum = (mass) x (velocity)

Momentum after the launch:

Spacecraft:  (1,000 kg) x (250 m/s) = 250,000 kg-m/s

Asteroid: (mass) x (-25 m/s)

Their sum:  250,000 - 25(mass) .

Their sum must be zero, so  250,000 kg-m/s = (25 m/s) x (mass)

Divide each side by  25 :  10,000 kg-m/s = (1 m/s) x (mass)

Divide each side by (1 m/s) :  10,000 kg = mass

A calorimeter contained 350.0 g of water [cp=4.18 J/(g °C)] at 24.0 °C. An electric current was passed through a heater placed i
Shtirlitz [24]
Cp shows the amount of energy needed to raise temperature by one degree for one gram of water. 

Formula for calculating cp is:
cp= \frac{energy}{(mass)*( temperature_{change} ))}  \\ temperature_{change}= \frac{energy}{(mass)*( cp))}   \\  \\ temperature_{change}= \frac{16700}{(350)*( 4.18))}  \\  \\ temperature_{change}=2.73 \\  \\ temperature_{final} =temperature_{initial}+temperature_{change} \\ temperature_{final}=24 + 2.73 \\ temperature_{final}=26.73

Final temperature is 26.73°C.
