I = 4 A
Explanation:
From Ohm's law, the voltage is given by
V = IR
or
I = V/R = (80 V)/(20 ohms)
= 4 A
Answer:
In a third class lever, the effort is located between the load and the fulcrum. If the fulcrum is closer to the load, then less effort is needed to move the load. If the fulcrum is closer to the effort, then the load will move a greater distance. ... These levers are useful for making precise movements.
Complete Question
A 0.025-kg block on a horizontal frictionless surface is attached to an ideal massless spring whose spring constant is 150 N/m. The block is pulled from its equilibrium position at x = 0.00 m to a displacement x = +0.080 m and is released from rest. The block then executes simple harmonic motion along the horizontal x-axis. When the displacement is x = 0.024 m, what is the kinetic energy of the block?
Answer:
The kinetic energy is
Explanation:
From the question we are told that
The mass of the block is
The spring constant is
The length of first displacement is
The length of first displacement is
At the the kinetic energy is mathematically evaluated as
Where is the change in energy stored on the spring which is mathematically represented as
=>
Substituting value
Answer:
A cell is the basic block of life and is always changing to fit its environment.
Explanation:
A cell is the basic founding block of a living organisms. In other words, a cell is the basic membrane unit which contains fundamental molecules of life. It is the cell that all living things are composed of.
The cell always changes with the surroundings and environment and it adapts to it. The cells requires a constant adjustments as the conditions inside and the outside the cells changes to keep a stable internal environment. Because the environment internally and externally is always changing, the cell continuously make adjustments to stay at or the near the set point.
Answer:
The moons of the outer planets are made of a mixture of ice and rock but our moon is made of only rock
Explanation:
When it comes to moon the elements silicon, iron & oxygen are classified as rocky materials and the elements carbon, nitrogen & Oxygen-Hydrogen compounds are classified as icy materials.
Our moon is primarily made of Silicon, aluminum, iron, calcium and iron.
Moons of outer planets are made of both icy materials and rocky materials.
