(100 watts) = 100 joules/second

(100 joules/second) x (3,600sec/hour) = 360,000 joules/hour

360,000 joules = 360,000 newton-meters

Weight of 2,000 kg on Earth = (2,000 kg) x (9.8 m/s²) = 19,600 newtons

(360,000 newton-meters) / (19,600 newtons) = <em>18.4 meters off the ground</em>

Newtons laws of motion
Viktor [21]

Answer:

Law 1. A body continues in its state of rest, or in uniform motion in a straight line, unless acted upon by a force.

Law 2. A body acted upon by a force moves in such a manner that the time rate of change of momentum equals the force.

Law 3. If two bodies exert forces on each other, these forces are equal in magnitude and opposite in direction.

A zero-order reaction has a constant rate of 2.30×10−4 M/s. If after 80.0 seconds the concentration has dropped to 1.50×10−2 M,
dolphi86 [110]

Answer:

Initial concentration of the reactant = 3.34 × 10^(-2)M

Explanation:

Rate of reaction = 2.30×10−4 M/s,

Time of reaction = 80s

Final concentration = 1.50×10−2 M

Initial concentration = Rate of reaction × Time of reaction + Final concentration

= 2.30×10−4 M/s × 80s + 1.50×10−2 M = 3.34 × 10^(-2)M

Initial concentration = 3.34 × 10^(-2)M

Hiw do we have day and night cycles? What is the speed of light?How and Why do we have seasons? Please answer ​
Ratling [72]

Answer:

1. Earth rotates on its axis; this causes us to experience day and night.

2. The speed of light is 186000 miles per second

3. The four seasons happen because of the tilt of the Earth's axis. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer.
