the one with the big mustard-colored stripe across it is the correct choice.
Answer:
111.8 m
Explanation:
Displacement is the change in position of an object. The SI unit of displacement is the meters. The displacement of an object can be calculated by determining the shortest distance from the starting point to the end point.
Since earl travels 50 m east and then 100 m north, let x represent the displacement. Therefore x is the shortest distance from starting to end. Earl movement forms a right angled triangle with x as the hypotenuse. Hence:
x² = 50² + 100²
x² = 12500
x = 111.8 m
Answer:
-540 kJ
Explanation:
P = Pressure which is applied to the piston = 180 kPa
= Final volume = 2 m³
= Initial volume = 5 m³
Work done is given by
The work required to compress helium is -540 kJ
Gravitational potential energy is the energy stored in an object due to its height above the Earth.
Explanation:
Gravitational potential energy is an energy that an object has as a result of its position in a gravitational field.
For an object which is near to Earth surface is gravitational acceleration is considered to be constant at 9.8 m/s².
Gravitational potential energy is also defined as the amount of work done to move an object having certain mass from one point to another point against gravitational force. It is calculated as mass multiplied by height to which an object is moved.
Some examples are water stored in a dam, ball kept on the top of a ramp, book kept of a shelf, etc.
The land form is formed by lava flows of low viscosity
Hope this helps! :)
