The correct answer is 40.5 Newtons just finished the quiz and 36.5 was incorrect.
Answer:
D. Electricity will flow if the electrons are bound loosely to their atoms in the material.
Explanation:
The continuous flow of charges is known as electricity (current). The flow of these charges are due to free or mobile electron within the atoms of the conductors. The materials which will allow current to pass through them, must have free or mobile electrons which are loosely bound to their atoms.
Thus, the correction for this question is "D"
D. Electricity will flow if the electrons are bound loosely to their atoms in the material.
Answer:
While lifting two object the machine needs the different momentum for different mass object.
Explanation:
- Momentum is the quantity of motion contained in an object. Usually it is measured by the product of mass and velocity.
- Momentum of first mass = 2 kg × 2 m/sec = 4 kg m/sec
- Momentum of second mass = 4 kg × 3 m/sec = 12 kg m/sec
- So the machine requires higher mass in motion for second object ( i.e. momentum) than the first one while lifting.
<span>Which statement best describes wavelength?
C. Wavelength is the length of one complete wave cycle.
As demonstrated by the Doppler effect, why does sound increase in pitch as a sound source approaches you?
B. The waves are closer together because the object is moving toward you.
Which statement best describes frequency and pitch?
A. Pitch is how frequency is perceived.
Hope these answer the question. Have a nice day.</span>
