The amplitude of a wave tells you how much energy it's carrying.
You might see light waves with large amplitudes if you're 10 miles from the sun, or if your little brother comes and points a flashlight right into your eye.
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.
Answer:
<em>Galvanómetro</em>
Explanation:
Un galvanómetro es un dispositivo eléctrico utilizado para <em>detectar la presencia de corriente y voltaje pequeños o para medir su magnitud.</em> Los galvanómetros se utilizan principalmente en puentes y potenciómetros.
If they both start from rest, and accelerate at the same rate, and A accelerates for twice as long as B does, then A ends up with TWICE the speed that B has.
