According to the formula
Where a is work, f is force and d is the distance that box was moved over. And from that formula, you can get that f = a/d and that is 54.83N of force
<h3>
Answer:</h3>
49500 kgm/s
<h3>
Explanation:</h3>
Data given;
- First car; Mass = 1100 kg
- Velocity = 30 m/s
- Second car; mass = 1100 kg
- Velocity = 15 m/s
We are required to calculate the total momentum of the system.
- We need to know that momentum is calculated by multiplying the velocity of a body by its mass.
- Therefore;
Momentum of the first car = 1100 kg × 30 m/s
= 33,000 kgm/s
Momentum of the second car = 1100 kg × 15 m/s
= 16,500 kgm/s
Therefore;
Total momentum = 33,000 kgm/s + 16,500 kgm/s
= 49500 kgm/s
Thus, the total momentum of the system is 49500 kgm/s
Answer:
The correct option is C: 0.31 s.
Explanation:
When the mass is then suddenly released we have:
Where:
F is the force
k: is the spring constant
Δy: is the spring displacement
Since the tension in the spring is zero, the force is the weight:
Where:
m is the mass of the object
g is the gravity
(1)
The oscillation period of the spring is given by:
(2)
By solving equation (1) for "k" and entering into equation (2) we have:
Since the spring will osclliates in a position between the initial position (when it is at rest) and the final position (when the mass is released and reaches the bottom), we have Δy = 2.5 cm = 0.025 m:
Hence, the oscillation period is 0.31 s.
The correct option is C: 0.31s.
I hope it helps you!
Answer:
The two components are biotic and abiotic components
Explanation:
The two components essential for the functioning of the ecosystem are:
Biotic Components:
These are the organic components like plants, pathogens, animals, human beings and other living components in the ecosystem that affects other living organisms, influences them and helps in shaping the ecosystem.
they require desired amount of nutrition and energy and energy for proper everyday functioning.
They are further classified as Producers, decomposers and consumers out of which producers prepare their own food by photosynthesis where consumers fulfills their requirement from producers and decomposers depend s on both producers and consumers for chemical breakdown into simpler and reusable forms.
Abiotic Components:
These are the inorganic components of the ecosystem like humidity, temperature, etc.
These are the non living components of the ecosystem which includes physical and chemical constituents of the environment which influences the biotic components and the ecosystem's functioning.
The abiotic components influences certain behaviors in living organisms like reproduction, growth, etc.
These components are synthesized by the process of photosynthesis by utilizing sunlight to convert these into organic compounds by primary producers which are further are the consumption of secondary producers thus increasing the organic content.
