lukranit [14]3 years ago
5 0

Answer:

F= 10.4 x10^6 N

Explanation:

A/C to Coulomb's law

F = k q1 q2 / r^ 2

F = 9x 10^9 x 2 x 3 / 72^2

F= 10.4 x 10 ^6 N

A 6.00 kg piece of solid copper metal at an initial temperature T is placed with 2.00 kg of ice that is initially at -10.0 ∘C. T
julsineya [31]

Answer:

T = 235.134^{\textdegree}C

Explanation:

The process is modelled after the First Law of Thermodynamics:

(6000\,g) \cdot \left(0.385\,\frac{J}{g\cdot ^{\textdegree}C} \right)\cdot (T -0^{\textdegree}C ) = (2000\,g)\cdot \left(2.108\,\frac{J}{g\cdot ^{\textdegree}C} \right)\cdot [0^{\textdegree}C -(-10^{\textdegree}C)] + (1500\,g)\cdot \left(334\,\frac{J}{g} \right)

The initial temperature of the piece of solid copper is:

T = 235.134^{\textdegree}C

A solenoidal inductor for a printed circuit board is being redesigned. To save weight, the number of turns is reduced by one-fif
marin [14]

Answer:

The current must be 5 times larger

Explanation:

The equation for Inductance, is given by;

L = (μ_o•N²•A)/l

Where;

μ_o is the permeability of the core material

N is the number of turns

A is the cross sectional Area

l is the length of the coil in meters

L is the inductance

However, we also need to find an expression for the Energy Stored, and the equation is given by;

U = (1/2)LI²

Where;

L is the inductance

I is the current.

We also know that U is proportional to the number of turns and the current.

Thus, we can conclude that;

N_2/N_1 = I_1/I_2

From the question, we are told that the number of turns is reduces by 1/5. Thus,

1/5 = I_1/I_2

So, I_2 = 5I_1

So the current must be 5 times larger

Suppose that you toss a rock upward so that it rises and then falls back to the earth. If the acceleration due to gravity is 9.8
telo118 [61]

The Rock's acceleration is 9.8 m/s^2 from the moment it leaves your hand until the moment it hits the ground. Its acceleration never changes. That's the acceleration of gravity as long as nothing is pushing the rock or holding it back.
