Explanation:
- Final velocity, v = 200 m/s
- Initial velocity, u = 0 m/s [Starts from rest]
- Acceleration, a = 6 m/s²
<u>To calculate</u> : Time (t)
★ v = u + at
→ 200 = 0 + 6t
→ 200 = 6t
→ 200/6 = t
→ <u>33.34 s ≈ t</u>
Because when plants and animals die the decomposers recycle the nutrients making then available again for the growth of plants or animals. So without decomposers the essential nutrients needed for the growth of plants and animals cannot be replaced.
Answer:
c. Rock, metal, and ices made of materials like water, ammonia, and methane condensed into a solid and grew large enough to gravitationally attract hydrogen and helium gas from the Solar Nebula.
Explanation:
Given the information about dependence of planetesimal composition on distance from the Sun and the existence of the frost line resulted in two main types of planets in our Solar System: the inner rocky planets and the outer gas giants. I have learned that planetesimal formation through accretion, and the types of materials that condensed at that distance from the Sun, will lead to the formation of Rock, metal, and ices made of materials like water, ammonia, and methane condensed into a solid and grew large enough to gravitationally attract hydrogen and helium gas from the Solar Nebula.
Answer:
<h2>100,000 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>100,000 J</h3>
Hope this helps you
Given,
Effort force = 120 N
Load force= 1050 N
Mechanical advantage of a pulley is given by the ratio of load force to the effort force.
Therefore, the mechanical advantage of the given pulley is 8.75.
