Answer:absorbs and emits electromagnetic radiation at all wavelengths
Explanation:
A blackbody is a believed to be a perfect absorber and reflector of radiation. Blackbody, in physics, refers to a surface that absorbs all radiant energy that falls on it. It is supposed that because incident visible light will be absorbed rather than reflected, the surface will appear black.
Answer:
Refraction is the slowing down of light waves as they pass into a different medium and speeding as they pass out.
hope it helps. plz mark me as brainliest.
Your answer is C
A constitutionally limited representative democratic republic [where] . . . the constitution, limits the power of government. We elect representatives, so it's not a pure democracy. But we do elect them by majority rule so it is democratic
Answer:
The impulse transferred to the nail is 0.01 kg*m/s.
Explanation:
The impulse (J) transferred to the nail can be found using the following equation:

Where:
: is the final momentum
: is the initial momentum
The initial momentum is given by:

Where 1 is for the hammer and 2 is for the nail.
Since the hammer is moving down (in the negative direction):
And because the nail is not moving:

Now, the final momentum can be found taking into account that the hammer remains in contact with the nail during and after the blow:
Since the hammer and the nail are moving in the negative direction:
=
= -9.7 m/s
Finally, the impulse is:

Therefore, the impulse transferred to the nail is 0.01 kg*m/s.
I hope it helps you!
