Answer:
13.15m/s
Explanation:
1600÷8=200s
1200÷90=13.33s
50÷15= 3.33s
(1600+1200+50)/(200+13.33+3.33) = 13.15m/s
The answer here could be pressure vs. temperature.
Think of PV=nRT. T is related to P the same way as n is (assuming all other variables are kept constant).
Answer:
Explanation:
mass, m = 1 kg
Position (2, 3 ) m
height, h = 2 m
acceleration due to gravity, g = 9.8 m/s^2
Here, no force is acting in horizontal direction, the force of gravity is acting in vertical direction, so the work done by the gravitational force is to be calculated.
Force mass x acceleration due to gravity
F = 1 x 9.8 = 9.8 N
Work = force x displacement x CosФ
Where, Ф be the angle between force vector and the displacement vector.
Here the value of Ф is 180° as the force acting vertically downward and the displacement is upward
So, W = 9.8 x 2 x Cos 180°
W = - 19.6 J
Thus, option (A) is correct.
Ummm what does this even mean I need a picture to help u
