Answer:
35.7kJ
Explanation:
we can calculate the amount of heat energy required , using this formula
Q = mcθ
where.
Q = heat energy (Joules, J)
m = mass of a substance (kg)
c = specific heat capacity (units )
θ = change in temperature (Celcius,C or Kelvin K)
Assume Specific heat capacity (c) of water =
mass =0.1 kg
If a rigid body is in translational and rotational equilibrium, then
1. The sum of all applied forces is zero.
2. The sum of all applied moments is zero.
3. There is no linear acceleration.
4. There is no rotational acceleration.
Answer:
<h2>D. erosion of the rule of law.</h2>
Explanation:
This can be described as an erosion of the rule law, because this type of policies is offering a huge gap inside the law, it can be distorted is such many ways, that at some point it won't represent an actual functional law. The subjectivity behind <em>"to avoid testifying in trials if they declare that their testimony could damage national security or interests" </em>is too much. A member of the legislature could avoid testifying into important cases just with the excuse that is national security.
Answer:
D
Explanation:
Motion in the X and the Y axis
<span>Speed of the sphere = 7 m/s
Distance between center of the circle to the center of the sphere = 1.8 m
Mass of the sphere = 6kg
Radius of the sphere = 0.89 m
Angular speed w = 5.62
Rotational kinetic energy of the sphere = 1/2 I x w^2
I being the moment of inertia, w being the angular speed
I = (2/5) x M x R^2 = (2/5) x 6 x 0.89^2 = 1.90
Rotational kinetic energy = 1/2 x 1.9 x 5.62^2 = 30 J</span>
