Explanation:
It is known that density is the mass present in per unit volume.
Mathematically, Density =
Since, it is given that is 1.18 , is 5.30 , and volume is 2 .
Therefore, mass of air that has entered will be - and it will be calculated as follows.
=
=
= 8.24 kg
Thus, we can conclude that mass of air that has entered the tank is 8.24 kg.
Answer:
57 N
Explanation:
Were are told that the force
of gravity on Tomas is 57 N.
And it acts at an inclined angle of 65°
Thus;
The vertical component of the velocity is; F_y = 57 sin 65
While the horizontal component is;
F_x = 57 cos 65
Thus;
F_y = 51.66 N
F_x = 24.09 N
The net force will be;
F_net = √((F_y)² + (F_x)²)
F_net = √(51.66² + 24.09²)
F_net = √3249.0837
F_net = 57 N
