Q:
Shalnov [3]

Answer:

Explanation:

We will use the KE equation you wrote here and fill in what we are given:

36=\frac{1}{2}m(12)^2 and isolating the m:

m=\frac{2(36)}{12^2} which gives us

m = .50 kg

Healthy pregnant women should get at least 150 minutes of moderate-intensity aerobic activity, spread over a 7-day period, each
kirill115 [55]

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.

During the time of pregnancy all women must be healthy and physically active. The ways for maintaining a very good health in the pregnancy time will be guided by the health care providers. Women should be highly active during and after pregnancy time. This helps in having a baby that is also very healthy.

Suppose that during any period of ¼ second there is one instant at which the crests or troughs of component waves are exactly in
kolezko [41]
<h3><u>Answer;</u></h3>

A. 4

<h3><u>Explanation;</u></h3>
  • <em><u>The period of a wave or periodic time is the time taken for a complete oscillation to occur. </u></em>For example its is the time taken between two successive crests or troughs.
  • <em><u>The beats or oscillation that occur in one second represents the frequency. Frequency is the number of complete oscillations or beats in one second in a wave.</u></em>
  • Frequency, measured in Hertz is given by the reciprocal of the periodic time.
  • Thus; <u><em>Frequency or beats per second = 1/(1/4) = 4</em></u>
  • <u><em>Hence , 4 beats per second</em></u>

What would happen to Mars (orbiting around the Sun, obviously) if its tangential velocity was reduced
Rama09 [41]

Answer:

It would eventually crash into the Sun

Explanation:

If the mars is orbiting around the sun, the gravitational force of attraction is between the sun and mars supply the necessary force required for the centripetal motion.

If a planet is in centripetal motion, it is constantly falling towards the sun with the acceleration equal to the gravitational strength at that point.

If the centripetal acceleration of the planet is removed, still the planet would accelerate linearly falling towards the sun.

Hence, if the planets tangential velocity was reduced to zero, It would eventually crash into the Sun
