Answer:
3.32 m/s
Explanation:
From the law of conservation of energy, the sum of mechanical and kinetic energy should be equal to the 10 J given. Potential energy is given by mgh where m is mass, g is acceleration due to gravity and h is the height. For this case, and l is string length, given as 2 m, \theta is given as 50 degrees. Kinetic energy is given by and it is this velocity that is unknown.
Answer:
This is the answer: The speed of a proton is about 5.0 × 10⁵ m/s
Explanation:
Because of the speeds of protons! :D
Newton should be the answer.
Answer:
Um could you translate this to english please ?
Explanation:
Answer:
166.6 N
Explanation:
Given that,
Force, F₁ = 20 N
Area, A₁ = 10 dm² = 1000 cm²
We need to find the new force if the area of the larger piston is 120 cm². According to Pascal's law,
So, the force on the larger piston is equal to 166.7 N.
