Displacement only measure how far between the starting and ending point. In this case, Lisa walks around the block as a circle so the starting point is the same as the ending point. Thus, displacement is 0mile.
On the other hand, distance measures exactly how far she walks. In this case, the distance is 1 mile, same as the perimeter of the block.
Temperature and pressure are directly proportional to each other. If this helps,please pick me the best. Also,please say thanks.
In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions.
Answer:
Option C is the correct answer.
Explanation:
Young's modulus is the ratio of tensile stress and tensile strain.
Bulk modulus is the ratio of pressure and volume strain.
Rigidity modulus is the ratio of shear stress and shear strain.
Here we are asked about Young's modulus which is the ratio of tensile stress and tensile strain.
Option C is the correct answer.
60.9 - 4.9= 56
56 is the net force
using the formula F = ma
56= 8a
a = 7
acceleration is 7ms^-2
