If you are operating a boat and you hear <span>the fog signal of another boat you cannot see, you should immediately reverse the engine or even stop it if you can do that (for the safety of everyone).
Then, you should ask someone else to go to the bow and assist in looking (maybe he/she can see the other boat that you cannot see) </span><span />
500J
Explanation:
Given parameters:
Weight of the body = 50N
Height = 10m
Unknown:
Work done = ?
Solution;
Work done is the force that moves a body through a particular distance in the direction of the force.
In this problem, we can solve the problem by relating work done to the potential energy used in lifting the mass.
The weight on a body, a force in the presence of gravity
weight(weight) = mg
where m = mass of body
g = acceleration due to gravity
Work done = Fxd
Where F = force on the body
d = distance moved
Potential energy = mgh
where h is the height
P.E = work done = Weight x height = 50 x 10 = 500J

<span>Ohm's law deals with the relation between
voltage and current in an ideal conductor. It states that: Potential difference
across a conductor is proportional to the current that pass through it. It is
expressed as V=IR. The correct answer from the choices listed above is option A. The resistance has increased. </span>
Explanation:
Artificial gravity can be created using a centripetal force. A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the normal force provided by the spacecraft's hull that acts as centripetal force.
Hope it helps.
Answer:
Precipitation is the formation of a solid from a solution. It is necessary to centrifuge the precipitate to exert sufficient forces of gravity to bring the solid particles in the solution to come together and settle
Explanation:
When you centrifuge precipitate it enables the nucleation to form.
Centrifuging the precipitate helps in determining whether a certain element is present in a solution or not.
