wow that looks really really easy so the answer is
Answer:
F=23N
Explanation:
The net force applied on the suitcase is the sum of the force F the man applies, the friction, the weight and the normal from the ground. We need only to look at the horizontal component of the forces to solve the question asked. On the horizontal, the net force would be the horizontal component of F minus the frictional force f, which always opposes movement (all the other forces are on the vertical component). So we have:
We now apply Newton's second Law on the horizontal:
And we calculate the horizontal component of F as , so we have
And to solve for F we do:
And substitute our values:
a plant cell is a cell that is a structural and functional unit of a plant an animal cell is a type of cell that dominates most of the tissue cells in animals. Animal cells are different from plant cells because they don't have cell walls and chloroplasts, which are relevant to plant cells.
Answer:
•marine biology.
Explanation:
A mechanical engineer is a professional individual who ensures the design of a mechanical assembly as well as the monitoring of its realization. His role involves the manufacturing of a prototype and developing new products for the company. Responsible for manufacturing, he advises the company and customers and assesses the risks and techniques used for its development. Finally, he supervises the installation and the market penetration of the product, as well as its maintenance.
A mechanical engineer can collaborate with many useful and complementary professions such as designers or marketers, it ensures the appearance and technical operation of the product. It is a job under high responsibility with projects that can be large.
Finally, he can also work in the construction sector, in the automotive industry, biomechanics, shipbuilding, aerospace production and aeronautics, railways, mechanics and metallurgy, robotics, textile machinery, etc.
Answer:
Vf = 9.622 m/s
Explanation:
Distance covered S=0.80m, Time t=0.087s and
g=9.81 m/s²
Required: Final velocity Vf when it hit the floor
Sol:
We have first find Vi so
Vi=Vit + 0.5 a t2
Vi =8.768m/s
Now Vf= Vi + at
Vf = 9.622 m/s
