Healthy pregnant women should get at least 150 minutes of moderate-intensity aerobic activity, spread over a 7-day period, each week - True
<u>Explanation:</u>
Women who are healthy but moderately active must be engaged with aerobic activities moderately. they should be engaged with this activities at least 2 and a half hours in all 7 days of a week. They must be engaged with this activity during the pregnancy time and also in the period after their delivery.

Women should be highly active during and after pregnancy time. This helps in having a baby that is also very healthy.
Answer:
The value is 
Explanation:
From the question we are told that
The depth of the mountain is 
Generally the velocity of the surface wave is mathematically represented as
=> 
=> 
Generally using the Froude number is mathematically represented as
Here V is the velocity of the current
Given that the waves do not travel upstream, then the flow of the current is supercritical which means that
=> 
=> 
Hence the minimum velocity of the current is
This because the velocity of the current is greater velocity of the surface wave , so minimum will be like the lowest possible value of V which is v
Answer: A cold front occurs when cold, denser air replaces the rising, less dense air mass. The reason this front brings in the rain is that as the rising warm air cools (as it rises to the cooler upper atmosphere) the moisture in it condenses into clouds that precipitate down as rain or snow.
power = workdone/timetaken

Answer:
Electronegativity
Explanation:
Element: <em>An element is a substance which can not be split into simpler units by an ordinary chemical process</em>
Electronegativity: This is the power of an atom in a molecule to attract electrons. The electronegativity of an element increase across the period in the periodic table and decreases down the group. The most electronegative elements are the reactive non metals.
Examples of electronnegative element include, Oxygen, Chlorine, Fluorine, Nitrogen, sulphur etc.
