Answer:
since there is no displacement, d = 0
Explanation:
hence work = f×d
= 150×0
= 0J
Answer:
The reason for the increase or decrease of the moon is <u>due to the angular perception of the moon.
</u>
Explanation:
Also called lunar illusion, this phenomenon is due to the position in which the moon is, it can be at the zenith or on the horizon, both distances are different from each other with respect to the position of the person.
The zenith is the highest part of the sky and the horizon the lowest.
When there are landmarks such as trees, buildings or mountains on the horizon, the illusion of closeness is given and the illusion of distance is misinterpreted.
But when looking up at the sky as there is no reference point there will be a failure in the perception of size.
The equivalent resistance of the two cylindrical conductors connected in parallel is 466 ohm.
<h3>
Resistance</h3>
Resistance is a measure of the opposition to flow of electric current. It is measured in ohms.
It is given by the formula:
Given that R₂ = 469 ohm, hence:
But l₁ = 6l₂, r₁ = (1/5)r₂, hence:
![R_1=\rho \frac{l_1}{A_1}=\rho *\frac{6l_2}{[\pi (1/5)r_2]^2} =150 * \rho \frac{l_2}{[\pi r_2]^2}=30*469=70350\ ohm](https://tex.z-dn.net/?f=R_1%3D%5Crho%20%5Cfrac%7Bl_1%7D%7BA_1%7D%3D%5Crho%20%2A%5Cfrac%7B6l_2%7D%7B%5B%5Cpi%20%281%2F5%29r_2%5D%5E2%7D%20%3D150%20%2A%20%5Crho%20%5Cfrac%7Bl_2%7D%7B%5B%5Cpi%20r_2%5D%5E2%7D%3D30%2A469%3D70350%5C%20ohm)

Answer:
the signal it takes 40 s to get the answer
Explanation:
As the satellite is in space the speed of radiation (waves9 is the speed of light in a vacuum, which is constant 3. 108 m / s, so we can use the uniform motion ratios to find the time.
v = d / t
t = d / v
t = 6.0 109 / 3. 108
t = 2 101 s
t = 20 s
This is the time it takes to get the signal from the earth to the satellite and it takes the same time to return, so since they send the signal it takes 40 s to get the answer
Answer:
The important thing about emotional health is being in control of their thoughts, feelings, and also behaviors.
Explanation:
Emotional health is an important part of overall health. People who are emotionally healthy are in control of their thoughts, feelings, and behaviors. They're able to cope with life's challenges. They can keep problems in perspective and bounce back from setbacks.
