Answer:
η = 0.0333 = 3.33 %
Explanation:
The efficiency of any device is defined as the ratio of the useful output obtained from that device to the input required by the device. Therefore, the general formula to find the efficiency of any device is given as follows:
where,
η = efficiency of hair dryer = ?
O = Useful Output Given by the Hair Dryer = 150 J
I = Input Energy Required by the Hair Dryer = 4500 J
Therefore,
<u>η = 0.0333 = 3.33 %</u>
I believe the answer is the second option. When two plates move together, lithosphere is destroyed. The lithosphere is the part of the ground that includes the uppermost mantle and the crust. It is where plate tectonics are situated. When these move, surely the lithosphere is affected and is changed.
Linear momentum is in a straight line and depends on the objects mass and velocity.
Angular (rotational) momentum depends on the objects mass, velocity, and radius.
Answer:
makes a transition from a high to a lower energy state
Explanation:
The emission spectrum is the spectrum of electromagnetic radiation emitted due to the transition from a state of high energy to a state of lower energy made by an electron in the atoms of the chemical element or compound. The emitted photons have an energy equal to the difference in energy between the two states.
