The answer to your question is B- They both described the inner part otherwise known as the inner core.
The inner core is hotter than the surface of the sun. The inner core is made out of iron and nickel. The inner core is extremely hot and is the last layer. It is a solid because of all the pressure from the other layers putting there weight onto this layer.
Answer:
<em>0.45 N</em>
Explanation:
<em>Let Recall that,</em>
<em> The power formula is: </em>
<em> P = E²/R </em>
Let A = the magnetic field
<em>Let L = length of wire = 9.00cm = 0.09 m </em>
let R = resistance of wire = 0.320 Ω
let v = velocity of the wire = 4 m/s
<em>Let E = across the wire voltage </em>
Let P = the power of the wire = 4.3 W
To Solve for E:
<em>The formula of E = √PR </em>
The Voltage from a magnetic field is given as,
E = vAL
We therefore Use E = E
√PR = vAL
to solve for A,
A= √PR/vL
BA= √4.3(0.32)/(4)(.09) -=0.173
A = 0.173 wA/m²
Let F be the pulling force
Let I be the current in the wire
P = I²R
<em>I = √P/R </em>
F = IAL
F = √P/RAL
F = √4.3/.32(0.173)(.09)
<em>F = 0.45N</em>
Answer:
The correct answer is A.
Objects in free fall accelerate due to <u>gravity</u>.
Explanation:
Momentum can help an object to keep its state of motion at a constant velocity when no external force is applied. It can never accelerate the object.
According to the laws of motion, we know that acceleration is produced in a body only when a Force is applied in the direction of motion of body.
During a free fall, only the force of gravity is acting on an object and that too in the direction of its motion. Hence, the acceleration produced in a free falling object is due to gravity.
