It depends the amount if mass the object haves and the amount of force it is applied to the object.
Answer:
they can organize a rally to pick up trash and plastic on the ground?
Answer:
the government's use and control of science. To clarify, I live in the U.S. I'm only interested in how the U.S. government dictates science. If you have any information or links that could educate me on this topic, I would be appreciative.
Explanation:
Answer:
C. 98 J
Explanation:
Mechanical energy is defined as the sum of kinetic energy (K) and potential energy (U):
E = K + U
where
is the kinetic energy, where m is the mass of the object and v its speed
is the potential energy, where g is the gravitational acceleration and h the height of the object relative to a reference point
For the object in this problem, the kinetic energy is zero, because it is not moving, so v = 0 and K=0. So the mechanical energy is just given by the potential energy, which is given by:
![E=U=mgh=(1 kg)(9.8 m/s^2)(10 m)=98 J](https://tex.z-dn.net/?f=E%3DU%3Dmgh%3D%281%20kg%29%289.8%20m%2Fs%5E2%29%2810%20m%29%3D98%20J)
Answer: 0.003 N
Explanation: Force (F) = Mass (m) * Acceleration (a)
Where acceleration is the rate of change of velocity (v/t)
v = 50 cm/s
t = 2 s
M = 12 g = 0.012 kg
a = v/t = 50/2 = 25 cm/s^2 = 0.25m/s^2
Hence F = m * a = 0.012 * 0.25 = 0.003 N
