THe answer will be C
because if you put somethin ht next to something cold it will become cooler and if you be two things that are hot next to each other they will remain hot.
Answer:
if it is a thiner one, yes it will fit because they can expand a pretty far distance
Explanation:
Answer:
r = 17.05 cm
Explanation:
Given that,
Length of silicon bar is 4 cm or 0.04 m
Resistance of the bar is 280 ohms
We know that the resistivity of the silicon is 640 Ωm
We need to find the cross-sectional radius of the bar. Let it is r.
Using definition of resistance of an object. It is given by :
A is area of bar, A = πr²
So,
So, the cross-sectional radius of the bar is 17.05 cm.
Answer:
2.59 T
Explanation:
Parameters given:
Current flowing through the wire, I = 29 A
Angle between the magnetic field and wire, θ = 90°
Magnetic force, F = 2.25 N
Length of wire, L = 3 cm = 0.03 m
The magnetic force, F, is related to the magnetic field, B, by the equation below:
F = I * L * B * sinθ
Inputting the given parameters:
2.25 = 29 * 0.03 * B * sin90
2.25 = 0.87 * B
=> B = 2.25/0.87
B = 2.59 T
The magnetic field strength between the poles is 2.59 T
Answer:
the total kinetic energy of its particle.
