Have you ever been in a bus, a train, or a car ?
What happens to you when it stops suddenly ?
A body in motion continues in motion unless
an external force acts on it and makes it stop.
Amy's body keeps moving forward when the train stops.
She pitches forward, and if she doesn't reach out and grab
a seat or a seated person, she may lose her footing and fall
on her face.
Choice - 'A' is a very good explanation.
The other choices aren't.
'C' is a good hunch, but it only applies to her feet.
The rest of her keeps going.
'D' is nonsense. There are no mysterious forces of
'repulsion' or 'attraction' on the train.
Answer:
<em>LED;</em>
The energy of photons emitted by an LED is dictated by the band gap of the semiconductor used – the energy required to make an electron–hole pair. When an electron and hole recombine in a radiative process, a photon carries away the extra energy.
<u><em>BULB</em></u>
In the light bulb, the flow of charge through the filament heats it up and causes it to glow. In this way, the light bulb converts electrical energy to heat energy and light energy. ... 1, chemical potential energy is converted to electrical energy, which is immediately converted to light energy and heat energy
This flow of charge converts chemical potential energy into electrical energy. In the light bulb, the flow of charge through the filament heats it up and causes it to glow. In this way, the light bulb converts electrical energy to heat energy and light energy. bulb have a fillament but LED have no filament they produce energy through clod process but bulb have a filament and they produce energy through hot process
Explanation:
This progression of charge changes over substance expected vitality into electrical vitality. In the light, the progression of charge through the fiber warms it up and makes it shine. Along these lines, the light believers electrical vitality to warm vitality and light vitality.
hope soo u can understand my point
Answer:
The hiker has to climb 941.26 to ''work off'' the calories.
Explanation:
Let's first find out how much energy the hiker gets from 150 food calories.
This is:
Energy = 150 * 4186
Energy = 627.9 kJ
To burn all of this off, we set it equal to the gravitational potential energy, and then solve for the height.
This is:
Gravitational Potential Energy (G.P.E) = 629700
G.P.E = mass * gravity * height
Thus,
mass * gravity * height = 629700
68 * 9.81 * height = 629700
height = 941.26 meters
Answer:
Below
Explanation:
To find the acceleration of the car, we can use this formula :
acceleration = net force / mass
acceleration = 2070 N / 1350 kg
acceleration = 1.53333 m/s^2
acceleration = 1.53 m/s^2
Hope this helps!
