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.

Answer:

u=8.868 m/s

Explanation:

The displacement of the ball is 4 meters

The final speed of the ball is 0.5 m/s

The initial speed of the ball is to be calculated. Using the equation of the rectilinear motion,

v^{2} =u^{2} +2as

Plugging the values in the above expression,

\\0.5^{2} =u^{2} +2*(-9.8)*4\\\\u^{2} =78.4+0.25\\\\u^{2} =78.65\\\\u=8.868 m/s

In outer space, where there is no gravity or air resistance, an astronaut pushes on two moon rocks, using 12N of force on each.
jek_recluse [69]

Answer:

A. Both rocks will push back at the astronaut with 12 N.

Explanation:

According to 3 rd law of Laws of motion of Newton , there is equal and opposite reaction so both the rocks will exert the same force of 12N on the astronaut separately . Acceleration of both of them will not be equal because their masses are different.

What is the average speed of a rock launched 700km from a catapult in 15 seconds
11Alexandr11 [23.1K]

Answer:

Therefore the average speed of a rock launched 700km from a catapult in 15 seconds is 46666.66 m/s or 46.66 km/s.

Explanation:

Given:

Total Distance Covered = 700 km = 700 × 1000 meter = 700000 m

Time taken = 15 seconds = 15 s

To Find:

Average speed of a rock = ?

Solution:

Average speed:

Average speed is defined as the rate of total distance covered in per unit time.

It is given as

\textrm{Average speed }=\frac{\textrm{Total Distance}}{Time}

Substituting the given values we get

\textrm{Average speed }=\frac{700000}{15}=46666.66\ m/s

Therefore the average speed of a rock launched 700km from a catapult in 15 seconds is 46666.66 m/s or 46.66 km/s.
