Answer:

On average, a total lunar eclipse will happen a bit more frequently than twice every three years. Every three and a half years, two total lunar eclipses will happen within the same year. Every 200 years, three total lunar eclipses happen in the same year.

2-5 a year I believe.

At least two lunar eclipses and as many as five occur every year, although total lunar eclipses are significantly less common. If the date and time of an eclipse is known, the occurrences. On average, a total lunar eclipse will happen a bit more frequently than twice every three years. Every three and a half years, two total lunar eclipses will happen within the same year. Every 200 years, three total lunar eclipses happen in the same year

Two passenger trains are passing each other on adjacent tracks. train a is moving east with a speed of 13 m/s, and train b is tr

alukav5142 [94]

Since the two trains are passing in opposite directions, so this means that their relative velocities will be the sum of the two trains that is:

relative velocity = (13 + 28) = 41m/s

a. The passengers aboard on train B will see that train A is moving at 41m/sec due east

b. The passengers aboard on train A will see that train B is moving at 41m/sec due west

Approximately how much heat energy does it take to raise 1 kg of water by 1 k?

Sidana [21]

Answer:

4186 Joules

Explanation:

The specific heat capacity of a substance is defined as the amount of heat needed to raise the temperature of 1 kg of the substance by 1 Kelvin. In formula,

$C_s = \frac{Q}{m \Delta T}$

where

Q is the amiunt of heat needed

m = 1 kg is the mass

$\Delta T = 1 K$

is the variation of temperature of the substance

For water, the specific heat capacity is $4186 J/(kg K)$ . This means that the heat energy required to raise 1 kg of water by 1 K is exactly 4186 J.
