The "transit method" means doing very careful precise measurements as the planet passes in front of its star.
It's too far away for us to see it directly, but when it "transits" the star, the brightness of the star decreases by a tiny tiny tiny bit, which we can measure.
If we can measure that dip with good enough precision, it tells us how much of the star's photosphere was blocked from our view when the planet temporarily got in the way. From that, we can estimate the planet's <em>size</em>.
Answer:
an elastic wave in the earth produced by an earthquake or other means
Explanation:
The amount of work done by the person is equal to 120 Joules.
<u>Given the following data:</u>
- Displacement = 15 meters.
To calculate the amount of work done by the person at a total height of 2 meters:
<h3>How to calculate work done.</h3>
In Science, work done is calculated by multiplying force and the displacement experienced by an object.
Mathematically, work done is given by the formula:
Substituting the given parameters into the formula, we have;
Work done = 120 Joules.

Answer:
The fulcrum of the metre stick is at the 40 cm mark
100 g * 10 cm = 1000 g-cm clockwise torque
x * 30 cm = 1000 gm-cm = counterclockwise torque for balance
X = 1000 / (40 -10) = 1000 / 30 = 33.3 gm at 10 cm to balance
Hey there!
Alright, it looks like you've got the second question on the top right, but I can't figure out the answer you've got for the first.
Using Newton's Second Law Of Motion, we have:
F = ma
We plug in our values:
F = 5(1)
That would give us 5 Newtons of force.
For the last one:
Even if two balls are given the same acceleration, the determining factor is <em>weight.</em> If a ball is lighter, it needs less acceleration to go faster. If it's larger, it needs more to make it go at that same speed. That's why that 5 newtons makes sense because it's 5 kilograms as opposed to 0.6 kilograms. It's heavier, and needs more force.
Hope this helped!
