Answer:
300 Nm ; 300 J
Explanation:
Given that:
Force (F) = 20 N
Distance (d) = 15 m
The kinetic energy (Workdone) = Force * Distance
Kinetic Energy = 20N * 15m
Kinetic Energy = 300Nm
K. E = 1/2
Answer:
There are 6.87 x 1023 atoms in 1.14 mol SO3, or sulfur trioxide :
I’m pretty sure you times them so 1 with A, 2 with e, 3 with C, and 4 with B
The answer is the electron microscope. It is a kind of
microscope that uses electrons to light a sample and make an enlarged
image. These kinds of microscopes have much better determining
power than light microscopes and can get much higher magnifications.
<h3><u>Answer;</u></h3>
<em>When a wave meets a boundary, the angle of the reflected wave is equal to the angle of the incident wave</em>
<h3><u>Explanation</u>;</h3>
- <em><u>Reflection is the property of waves in which the waves bounces back upon meeting or hitting the surface of an object or a boundary.</u></em> It may also refer to the change in the direction of a wave when it meets an interface between two media.
- Therefore, when a wave such as light waves meets an opaque surface, they will bounce back off the surface.
- <em><u>The reflection of waves obeys the Laws of reflection such that the angle of reflection is equal to the angle of incident wave.</u></em>
