i love the jigsaw classroom. it is elite
Explanation:
Answer:
11. 5 N to the left.
12. 10 N to the right.
Explanation:
11. Determination of the net force.
Force in the left direction (Fₗ) = 10 N
Force in the right direction (Fᵣ) = 5 N
Net force (Fₙ) =?
The net force can be obtained as follow:
Fₙ = Fₗ – Fᵣ (Since the forces act in opposite direction)
Fₙ = 10 – 5
Fₙ = 5 N to left
Thus, the net force is 5 N to the left.
12. Determination of the net force.
Force in the right direction 1 (Fᵣ₁) = 5 N
Force in the right direction 2 (Fᵣ₂) = 5 N
Net force (Fₙ) =?
The net force can be obtained as follow:
Fₙ = Fᵣ₁ + Fᵣ₂ (Since the forces act in the same direction)
Fₙ = 5 + 5
Fₙ = 10 N to the right
Thus, the net force is 10 N to the right.
Answer: 350 newton
Explanation:
Force needed = ?
mass = 10kg
Acceleration = 35m/s2 (The SI unit of acceleration is metre per second square)
Recall that Force is the product of mass of an object and the acceleration by which it moves.
Force = mass x acceleration
Force = 10kg x 35m/s2
Force = 350N
Thus, the force needed is 350 newton
A nitrogen atom with 7 protons and 8 neutrons has a mass number of 15amu however on the periodic table the atomic mass for nitrogen is 14.01
12 mg = 0.012 g
12 mg = 1.2e-5 kg
75 kg = 75,000 g
