I think the correct answer should be B<span>a(ClO3)2 = BaCl2 + 3O2. In balancing chemical reactions, it important that the number of atoms of each element in each side of the reaction should be the same. Hope this answers the question. Have a nice day.</span>
Answer:
Atmospheric pressure is the pressure exerted by the weight of the atmosphere.
Atmospheric Pressure = density of Mercury X acceleration due to gravity X height of column of the mercury
Answer:
The total normal force acting on the system is approximately 58.8 N
Explanation:
The masses arranged in the stack are;
3 kg, 2 kg, and 1 kg
The mass of the stack system, m = 3 kg + 2 kg + 1 kg = 6 kg
Weight = The force of gravity on an object = m·g
Where;
m = The mass of the object
g = The acceleration due to gravity ≈ 9.8 m/s²
∴ The weight of the stack system, W ≈ 6 kg × 9.8 m/s² ≈ 58.8 N
The direction of the weight force = Perpendicular to the surface (acting downwards)
From Newton's third law of motion, the normal force acts perpendicular to the plane and it is equal in magnitude to the force acting perpendicular to the plane
∴ The magnitude of the total normal force acting on the system = The magnitude of the weight of the system ≈ 58.8 N
The (magnitude of the) total normal force acting on the system ≈ 58.8 N
Answer:
Efficiency of machine=4.9
Explanation:
We are given that
Mass of load=100 kg
Effort=20 N
Velocity ratio=10
We have to find the efficiency of machine.
Load=
Efficiency=
Using the formula
Efficiency of machine=
Efficiency of machine=
Efficiency of machine=4.9
The net force on the cylinder depends on several independent variables such as mass, acceleration, velocity, time, etc, and it is given as F(net) = ma.
<h3>
Net force exerted on the cylinder</h3>
The net force on the cylinder is calculated from Newton's second law of motion.
F(net) = ma
F(net) = m(v/t)
where;
- m is mass of the cylinder
- a is acceleration of the cylinder
- v is velocity of the cylinder
- t is time of motion of the cylinder
Thus, the net force on the cylinder depends on several independent variables such as mass, acceleration, velocity, time, etc, and it is given as F(net) = ma.
