If the coefficient alpha for a stress scale was computed to be 0.80, the scale would be strongly reliable. A coefficient alpha that is at least 0.70 and above is considered to have a strong internal consistency, which means the items in the scale are closely related as a group.
Answer:
D (not so sure, look in the explanation and judge yourself)
Explanation:
Assume that the acceleration due to gravity is 9.81 m/s^2 downwards
Minimum force required = 0.25 x 34 x 9.81
= 83.385 N
So technically the force need to be greater than 83.385 so the answer should be d, not really sure if it should be b though really depends on the acceleration due to gravity.
The thermal energy will be transferred from the air to the surface. Hence, the answer is false.
Thermal energy can be transferred from higher temperatures to lower temperatures. It is obey the second law of thermodynamics
"At a very microscopic level, it simply says that if you have a system that is isolated, any natural process in that system progresses in the direction of increasing disorder, or entropy, of the system."
It means that heat energy transferred from the higher temperature and the lower temperature states will absorb heat energy from the surrounding. The thermal energy will be transferred through conduction, convection, or radiation.

Answer:
1400 N
Explanation:
→ Force = Mass × Acceleration
→ F = (70 × 20) N
→ <u>F = 1400 N</u>
Answer:
ossicles (comprising of hammer, anvil, and stirrup)
Explanation:
The hammer, anvil and stirrup are also known as the malleus, incus, and stapes, respectively which are the part of the middle ear.
They transmit the sound vibrations from eardrum to cochlea by a level mechanism. The generate mechanical advantage by multiplying the force over a shorter distance from the input of a smaller force at a larger distance.
