Answer: The volume of an irregularly shaped object is 0.50 ml
Explanation:
To calculate the volume, we use the equation:

Density of object = 
mass of object = 3.0 g
Volume of object = ?
Putting in the values we get:


Thus the volume of an irregularly shaped object is 0.50 ml
Explanation:
Given that,
The slope of the ramp, 
Mass of the box, m = 60 kg
(a) Distance covered by the truck up the slope, d = 300 m
Initially the truck moves with a constant velocity. We know that the net work done on the box is equal to 0 as per work energy theorem as :

u and v are the initial and the final velocity of the truck
(b) The work done on the box by the force of gravity is given by :

Here, 


W = -24550.13 J
(c) What is the work done on the box by the normal force is equal to 0 as the angle between the force and the displacement is 90 degrees.
(d) The work done by friction is given by :


Hence, this is the required solution.
Answer:
R.E.T.A.R.D.A.T.I.O.N
Explanation:
It won't let me spell it normal
Its a proces of combustion "burning"humans produce carbon dioxide,rocks<plants whatever is burning energy
Answer:
Net force = 800 – 650
= 150 N
150 = (800 ÷ 9.8) a
a = 1470 ÷ 800
= 1.8375 m/s^2, downwards
