Answer:
The answer to your question is weight = 1667 N
Explanation:
Data
density = 2.40 x 10³ kg/m³
volume = 0.0708 m³
Force = 66.7 N
weight of the block = ?
- Formula
density = mass / volume
- Solve for mass
mass = density x volume
-Substitution
mass = (2.40 x 10³)(0.0708)
-Result
mass = 169.92 kg
-Calculate the weight of the body
weight = mass x gravity
-Substitution
weight = 169.92 x 9.82
-Simplification
weight = 1666.9 N ≈ 1667 N
The statement that best describes electrons is that t<span>hey are negative subatomic particles and are found surrounding the nucleus.</span>
Answer:
power is given by work done divide time taken
P=w/t
therefore Pt=w
270x42=11,340.J
It depends on the type of question, mechanical condition and given values,
You can use the formula,
Coefficient of kinetic friction = Force of Kinetic friction / Normal force (perpendicular to contacting surfaces)
Hope this helps!
The weight should be shared between the two string equally. Therefore, tension in each string, T is;
T = 120 N/2 = 60 N
