The work done is 400 J
Explanation:
The work done by you in pushing the box along the slope is given by

where
F is the magnitude of the force applied
d is the distance covered by the box along the slope
Here we have the following:
F = 200 N is the magnitude of the force applied
is the distance covered, where
h = 1 m is the vertical rise
is the slope of the plane
Substituting and solving, we find

Answer:
The first step in turning a rock into a sediment is Compaction
.
Explanation:
Lithification is a process of changing rock into sediments. There are two steps for a rock to lithify. These steps are as follows
- The first step of lithification is compaction where sediments are erosed together by weight of the it. Thus, the upper layers of sediments causes compaction of lower layers.
- The next process of lithification is cementation. In this fluids fill the space between the loose particles.
Hence, the first step for turning rock into sediments is compaction.
Answer:
Reduce you're speed, and let the other vehicle pass you
The mass on the spring is 0.86 kg
Explanation:
The period of a mass-spring system is given by the equation

where
m is the mass
k is the spring constant
In this problem, we have:
k = 88.7 N/m is the spring constant
The system makes 15 oscillations in 9.24 s: therefore, the period of the system is

Now we can re-arrange the first equation to solve for the mass:
