Hello.
h=150 m
u(initial speed)=0
t=5.5 s
<span>v(final speed) =?
</span>
2gh=v^2-u^2
Have a nice day
Yes, <span> the moon fall partly into earth's shadow when it is in its full size</span>
Answer:
To drive at high speed around an unbanked horizontal curve on the earth.
Explanation:
Garvitational pull on on eart is 6 times more than on the moon. On. Earth, the vehicle will have more grip on the surface due to its weight. This grip will reduce its tendency to skid off the horizontal curve when compared to driving in the same unbanked horizontal curve on the moon.
Answer:
by doing rapid shallow breathing and pursed lip breathing
Explanation:
Pressure with in the chest wall and the outside of the lungs remains negative because the intrapleural pressure is always lesser than the intra-alveolar pressure or atmospheric pressure. In general forced expiration leads to an increasing positive pressure in pleura. This happens because the pleura airway gets compressed and the size of airway reduces thereby forcing expiration.
People who are able to resist airway can increase airflow by doing rapid shallow breathing and pursed lip breathing
Answer:
<em>11.a) </em><em>Car B </em><em>is faster than </em><em>Car A</em><em>. This is because Car B covers more distance in less time, whereas Car A covers less distance in more time. Now, as we know that distance is directly proportional and time is inversely proportional to speed. In Car B, a larger distance and less time and a smaller distance and more time in Car A, indicates that the speed of Car B is more than the speed of Car A.</em>
<em>b) </em><em>Car B</em><em> accelerates faster than </em><em>Car A. </em><em>We know that, the acceleration is directly proportional to the change in linear velocity and inversely proportional to time taken. Here, The overall journey of </em><em>Car B </em><em>is short, whereas for </em><em>Car A, </em><em>it's longer. Also, as previously mentioned that the final speeds of Car B is more than Car A [remembering that both Cars start from the origin(rest)]. Hence, the change of velocity in Car B is more than Car A. Hence so.</em>
