Explanation:
We have,
A projectile is launched at an angle 60° to the horizontal with some initial speed 45 m/s.
The cliff is 265 m high.
(A) The final velocity of the projectile is given by :
(B) The maximum height of the projectile is given by :
(C) The horizontal range of the motion is given by :
<span>A virus particle is not a complete cell but an intracellular parasite. Hence, it cannot reproduce without the help of a host cell. Once inside a host cell, the virus is made in such a way that it replicates itself. There are two ways in which viruses reproduce or multiply their numbers: the lytic cycle and the lysogenic cycle. </span>
Answer:
The force required to maintain an object at a constant velocity in free space is equal to Zero.
The volume of a substance can directly be calculated by
the ratio of mass and density. That is:
volume = mass / density
Since the mass is 4.5 kg or 4500 grams, therefore:
volume = 4500 g / (8.89 g / cm^3)
<span>volume = 506.19 cm^3</span>
