Answer:
Explanation:
1. The law that best illustrate this is Newton's first law of motion, which is also called the law of inertia
The law states that every object will continue in the sate of rest or in uniform motion except it is acted upon by an external force. The bike stop moving because it hits a curb.
Inertia: This is the reluctance or the tendency for a body to be in its state of rest or uniform motion.
And Maya is thrown into the air due to it inertia.
2. The Law that best illustrate this is Newton's Third law of motion.
This law states that to every action there is an equal and opposite reaction.
As the bird uses his wind to push air downward, air pushes upward on the bird allows it to fly. the upward and downward movement of air are both equal but opposite reaction.
3. The Law that illustrate this is Newton's second law of motion.
This law can be summarize as force is directly proportional to mass and acceleration.
Because the mass of the second box is smaller than the first box that was why its accelerate at a greater rate.
Answer:
*The increase in thermal energy the maximum emission of radiation changes according to Wien's law
*The increase in thermal energy he intensity of the energy increases significantly, proportional to the fourth power of the temperature
Explanation:
When bodies heat up, the vibrations of their molecules and atoms increase, due to the energy, therefore the internal energy (Temperature) of the body also increases.
The increase in thermal energy relaxes in an increase in body temperature, when this happens the maximum emission of radiation changes according to Wien's law that gives a shift towards the visible as the temperature increases.
Furthermore, the intensity of the energy increases significantly, in a curve described by the Planck expression.
These increases are proportional to the fourth power of the temperature

Answer:
a) Magnitude of maximum emf induced = 0.0714 V = 71.4 mv
b) Maximum current through the bulb = 0.00793 A = 7.93 mA
Explanation:
a) The induced emf from Faraday's law of electromagnetic induction is related to angular velocity through
E = NABw sin wt
The maximum emf occurs when (sin wt) = 1
Maximum Emf = NABw
N = 1
A = 4 cm² = 0.0004 m²
B = 6 T
w = (284/60) × 2π = 29.75 rad/s
E(max) = 1×0.0004×6×29.75 = 0.0714 V = 71.4 mV
Note that: since we're after only the magnitude of the induced emf, the minus sign that indicates that the induced emf is 8n the direction opposite to the change in magnetic flux, is ignored for this question.
b) Maximum current through the bulb
E(max) = I(max) × R
R = 9 ohms
E(max) = 0.0714 V
I(max) = ?
0.0714 = I(max) × 9
I(max) = (0.0714/9) = 0.00793 A = 7.93 mA
Hope this Helps!!
Answer:
i believe there is something wrong in your question
Explanation:
Human building a drainage system could affect the water cycle because :
C. water would be directed to a new location because of the drains
This could potentially changed the natural occurrence that usually happened within the water cycle
hope this helps
