Answer:
1.The Washington Monument is 555 feet tall.A.If 1 meter = 3.28 feet, what is the height of the Washington Monument in meters? 1,820.4 mB.A worker assigned to the restoration of the Washington Monument is checking the condition of the stone at the very top of the monument. A nickel with a mass of 0.005 kg is in her shirt pocket. What is the gravitational potential energy (GPE) of the nickel at the top of the monument?GPE = mghGPE = (0.005 kg)(0 m/s2)(1,820.4 m)GPE = 0 JC.What is the kinetic energy (KE) of the nickel in her shirt pocket at the top of the monument?KE = 1/2mv2KE = (0.5)(0.005 kg)(0 m/s)2KE = 0 JD.If the nickel accidentally falls out of her pocket, what will happen to the gravitational potential energy (GPE) of the nickel as it falls to the ground?The GPE will decrease because the height is decreasing.E.If the nickel accidentally falls out of her pocket, what will happen to the kinetic energy (KE) of the nickel as it falls to the ground
Explanation:
Answer:
x=7227
y=1678
(7227,1678)
Explanation:
Ok, check the picture I attached you, because of the problem don't give us aditional information, let's asume that the projectile is fired from an initial position x=0 and y=0. Now let's use projectile motion equations, but firs let's find the initial velocity components in x-axis and y-axis:
Now, let's find the x coordinate with this equation:
Finally asumming a gravity constant g=9.8, let's find the y coordinate with the next equation:
The answer is 'negative charge and contains less sodium than outside of the cell'. This is called the resting potential. After depolarization, the ion channels open up and the intracellular sodium ions are pumped out of the neurons hence making the inside of the neurons electronegative compared to the extracellular matrix. The membrane potential is usually -70mV.
When a pendulum swings, potential energy is transformed into kinetic energy, and then back again to potential energy as the speed and elevation of the pendulum vary during the motion
