The answer is D. Unconditioned
The response to an unconditioned stimulus that occurs naturally without learning and involuntarily triggers reaction is known as an unconditioned response. For example, you smell your favorite food while being cook may make you instantly feel hungry.
Answer:
the rate of heat transfer after the system achieves steady state is -3.36 kW
Explanation:
Given the data in the question;
mass of water m = 50 kg
N = 300 rpm
Torque T = 0.1 kNm
V = 110 V
I = 2 A
Electric work supplied W₁ = PV = 2 × 110 = 220 W = 0.22 kW
Now, work supplied by paddle wheel W₂ is;
W₂ = 2πNT/60
W₂ = (2π × 0.1 × 300) / 60
W₂ = 188.495559 / 60
W₂ = 3.14 kW
So the total work will be;
W = 0.22 + 3.14
W = 3.36 kW
Hence total work done on the system is 3.36 kW.
At steady state, the properties of the system does not change so the heat transfer will be 3.36 KW.
The heat will be rejected by the system so the sign of heat will be negative.
i.e Q = -3.36 kW
Therefore, the rate of heat transfer after the system achieves steady state is -3.36 kW
Use the formula for mechanical advantage of simple machines. As for a lever, use formula below
mechanical advantage = force output/force input
where
Force input = 330 N
mechanical advantage = 1.6
substitute all the given data, we will get Force output
Force output = 528 N
I encountered this same question, these were the choices given.
1). In the atom, the particles of the cathode rays are embedded in a diffuse cloud of positive charge.
<span>2).Cathode rays have mass. </span>
<span>3).Matter contains positive and negative charge. </span>
<span>4).The positive component of matter is also particulate in nature. </span>
<span>5).Particles of the cathode rays are fundamental to all matter. </span>
<span>6).An atom is divisible. </span>
<span>7).Particles of the cathode rays are negatively charge.
</span>
There are more than one correct statement. These statements are:
<span>2).Cathode rays have mass.
</span><span>3).Matter contains positive and negative charge.
</span>5).Particles of the cathode rays are fundamental to all matter. 6).An atom is divisible.
I'm pretty sure your answer should be Bonds. Hope this helps! =^-^= (Maybe brainliest please?)
