Explanation:

Crystizaltion of magma turns into indeginous rocks which then turns into sediment after weathering and erosion.

The distance traveled by the box before stopping, when the student slides the box across the floor  to his friend, at the given coefficient of kinetic friction is 4.8 m.

The acceleration of the box across the floor is determined by applying Newton's second law of motion.

∑F = ma

-Ff = ma

-μmg = ma

-μg = a

-(0.52 x 9.8) = a

- 5.1 m/s² = a

The distance traveled by the box before it stops is calculated  as follows;

v² = u² + 2as

where;

0 = (7)² + 2(-5.1)s

0 = 49 - 10.2s

10.2s = 49

s = 49/10.2

s = 4.8 m

Thus, the distance traveled by the box before it stops is 4.8 m.

Answer:

[tex]R= 960 \: Ohm[/tex]

Explanation:

P = 60 W

V = 240 V

[tex]P= VI[/tex]

[tex]\implies I= \frac{P}{V}[/tex]

[tex]\implies I= \frac{60}{240}[/tex]

[tex]\implies I= 0.25 A[/tex]

Now, by Ohms law

[tex]R= \frac{V}{I}[/tex]

[tex]\implies R= \frac{240}{0.25}[/tex]

Explanation:

It is to be noted that the electric field that has been induced is (-B₁ A/2[tex]\pi[/tex]R)θ. This is obtained by using the vector units in the Cylindrical Coordinate System.

Cylindrical Coordinates are simply defined as a component of a coordinate system that is used to locate a location in space using its polar coordinates and vertical distance from the polar plane.

The formula for Induced Electric Field is given as:

∫ E · dl = ∈

If we replace ∈ with -B₁A and 2[tex]\pi[/tex]R for dl then

∫ E · dl = -B₁A. Thus, we can state that

E∫ dl  = -B₁A

Replacing or substituting 2[tex]\pi[/tex]R for ∫ dl ·E(2πR)  = - B₁A

We can thus rearrange the equation to read:

E · E = ([tex]\frac{-B1A}{2\pi R}[/tex])θ

It is to be noted that the circumference of a circle is the integral of the length of the element. While θ, which in this case is the unit vector refers to the Cylindrical Coordinate and the direction of the electric field.

Answer:

4.3s

Explanation:

a=v-u/t

t=v-u/a

t=26-20/1.4=4.28

=4.3

Answer:

155.6 hrs

Explanation:

5   =   100 (1/2)^n      n = 4.32 half lives

4.32 * 36 = 155.6 hrs

The required, 155.58 hours will have elapsed when 5.00 grams of the isotope remains.

The half-life of the element is defined as the time span in which the element grows or decays half of its whole composition of growth and decay.

Here,
The decay of a radioactive substance can be modeled by the following equation,

[tex]N(t) = N_o (1/2)^{t/T}[/tex]

where N₀ is the initial quantity of the substance, N(t) is the quantity remaining after time t has elapsed, and T is the half-life of the substance.

In this problem, we are given,

N₀ = 100.0 g

N(t) = 5.00 g

T = 36.0 hours

We want to find the time t that has elapsed. Rearranging the equation above, we can solve for t,

t = T (log N₀ - log N(t)) / log 2

Substituting the given values, we get,

t = 36.0 hours x (log 100.0  - log 5.00 ) / log 2

t = 36.0 hours x 4.643 / 0.693

t = 155.58 hours

Therefore, approximately 155.58 hours will have elapsed when 5.00 grams of the isotope remains.
