Answer:
The mechanical energy of this object is 10.8 Joules.
Explanation:
Mechanical energy is the sum of kinetic energy and potential energy.
m = mass of the object
v = velocity of the moving object
h = height at which an object is placed
g = Acceleration due to gravity
We have : m = 2 kg. v = 1 m/s , h = 1/2 m
The mechanical energy of this object is 10.8 Joules.
Answer:
The total voltage of the circuit is 18 volts.
Explanation:
We have, three identical resistors of resistance 3 ohms are connected in series in a circuit.
For a series combination, the equivalent resistance is given by the sum of individual resistances i.e.
Let V is the voltage of the battery if the current in the circuit is 2 A. So,
So, the total voltage of the circuit is 18 volts.
The sun is the mother star of the solar system, which only emits light to half of the planet, while the other part is always dark.
The sun emits light towards the earth, which dominates all life on earth. The movements of the Moon around the Earth and of the Earth around the Sun are complex. Movements of rotation around their own axes are superimposed on movements of orbital translation. The Earth and the Moon rotate around their own axes: This is rotation.
