a. work is the time it takes to move an object once acted upon by a force
Answer:
Vmax=11.53 m/s
Explanation:
from conservation of energy
![E_A} =E_{B}](https://tex.z-dn.net/?f=E_A%7D%20%3DE_%7BB%7D)
Spring potential energy =potential energy due to elevation
0.5*k*x²= mg
=mgh
0.5*k*2.3²= 430*9.81*6
k=9568.92 N/m
For safety reason
k"=1.13 *k= 1.13*9568.92
k"=10812.88 N/m
agsin from conservation of energy
![E_A} =E_{C}](https://tex.z-dn.net/?f=E_A%7D%20%3DE_%7BC%7D)
spring potential energy=change in kinetic energy
0.5*k"*x²=0.5*m*![V_{max}^{2}](https://tex.z-dn.net/?f=V_%7Bmax%7D%5E%7B2%7D)
10812.88 *2.3²=430*![V_{max}^{2}](https://tex.z-dn.net/?f=V_%7Bmax%7D%5E%7B2%7D)
=11.53 m/s
Use Force=Mass x Acceleration (newtons second law states force is directly proportional to the acceleration) so you can say that the force is negative and solve for Acceleration.
<span>Matching the boundary with its characteristics
1. Convergent - C. Compression
2. Divergent - B. Along ocean ridges
3. Transform - A. Along strike-slip faults
The compression that occur in the convergent boundary causes the reverse fault in the earth crust.
So in the divergent boundary two crust plates move apart causing a normal fault along the ocean ridges.
The faults in the transform boundary happens at the place where plates slide laterally.</span>
Answer:
Atomic radius decreases moving from left to right across a period.
Explanation:
When we move left to right across a period, the size of atoms generally decreases. It is because within the period the outer electrons are in same valence shell and the number of electrons and proton increases moving from left to right across the the period. It increases the effective nuclear charge resulting in the increased attraction of electron to the nucleus that causes the decreased radius of the atoms.
