<span>We can use a simple equation to calculate the increase in gravitational potential energy.
PE = mgh
m is the mass of the object
g is the acceleration due to gravity
h is the change in height
PE = mgh
PE = (3.75 kg) (9.80 m/s^2) (1.5 m)
PE = 55.1 Joules
The increase in gravitational potential energy is 55.1 Joules.</span>
Answer:
longitudinal
Explanation:
because particles of medium through which the sound is transported vibrate parallel to the direction of the sound wave moves
Answer: 9.81m/s^2
Explanation: since it’s free fall and friction is neglected, the magnitude of the ball’s acceleration will be equal to the general acceleration due to gravity which is 9.81m/s^2
To solve this problem it is necessary to apply the equations related to the law of Maus.
By the law of Maus we know that
Where,
= Intesity of incident light
I = Intensity of polarized light
With our values we have that
6V/m
Then
Therefore the maximum value of the transmitted E vector is 3V/m
Answer:
Climate change, where there is an increase in the average temperature, due to continuous human activities. These activities increase greenhouse gases in the atmosphere.
Explanation:
Alaska is the largest state in the United States, and it has a cold climate. The climate changed over time as human activities such as coal mining contributed to greenhouse gas emissions leading to global warming. Over the years. the variations in weather leading to climate change melt the permafrost (frozen ground below the soil surface) causing ocean waves to erode the land and destroy property.
