Answer:
K_{total} = 19.4 J
Explanation:
The total kinetic energy that is formed by the linear part and the rotational part is requested
let's look for each energy
linear
= ½ m v²
rotation
= ½ I w²
the moment of inertia of a solid sphere is
I = 2/5 m r²
we substitute
= ½ mv² + ½ I w²
angular and linear velocity are related
v = w r
we substitute
K_{total} = ½ m w² r² + ½ (2/5 m r²) w²
K_{total} = m w² r² (½ + 1/5)
K_{total} = 
m w² r²
let's calculate
K_{total} = 6.40 16.0² 0.130²
K_{total} = 19.4 J
Answer: a. boiler - I. part of a coal-fired power plant.
b. combustion chamber - I. part of a coal-fired power plant.
c. condenser - III. part of a coal-fired power plant and part of a nuclear power plant.
d. control rod - I. part of a coal-fired power plant.
e. generator- III. part of a coal-fired power plant and part of a nuclear power plant.
f. turbine - III. part of a coal-fired power plant and part of a nuclear power plant.
Explanation:
a. Boiler: It is used in the coal power plant to heat the water used for producing electricity. The boiler keeps the temperature of water or steam at a desired level.
b. Combustion chamber: It is used for combustion of coal and using thermal energy for electricity generation.
c. Condenser; It is used in both nuclear and coal power plants. It condense and receive from the turbine.
d. Control rod: It is used in the nuclear power plant for controlling the nuclear fission and fusion reactions of heavy metals.
e. Generator: It converts the thermal energy into electrical energy.
f. Turbine: The turbine blades move with the effect of steam or any form of energy and the energy so produce is used for generating electricity in generator.
Answer:
1.2 m/s^2
Explanation:
I will ignore gravity and friction....and will choose 25 N as UP and 40 N to Left (see diagram)
Resultant force: R^2 = 25^2 + 40^2 R = sqrt(2225)=47 N
F = ma
F/m = a
47 N / 40 kg = a = 1.2 m/s^2
The answer is A because when you relocate something you’re moving it to a different place from where you had it at first
