We could send aliens information that is good about us not the bad things. Don't share weaknesses, because that could probably lead to some bad things. We should share valuable info with the aliens.
Answer:
The correct answer is - option B.
Explanation:
Prior to third trimester mother feels heavier breathing and experience difficulty in breathing normally that is due to the head of the baby present under the one of the rib and pressure on the diaphragm.
This get less due to the shift of the baby as the baby stat to move further into pelvis. Moving of the head of the bay towards down into pelvis helps in making breathing easier.
Thus, the correct answer is - option B.
The weight of an object is the force of gravity exerted on that
object and the mass of an object is the amount of matter it has, and it
stays the same wherever you are, regardless of gravity.
So, here the mass of object is 40 kg on earth,
it means it has mass of 40 kg on moon also, but when we are calculating the
weight of an object we used the following formula,
F=mg
Where F is the weight of an object in Newton
and m is the mass of object in kilogram and g is the gravity
Now here gravity on the moon is 1.6 m/s2 and m
is 40 kg
So, F = 40 x 1.6
<span>F = 64 N</span>
<span>mass of the object on moon is 40kg and weight of an object on moon is 64N.</span>
