the answer is radioactive dating

The spring constant for a spring is stretched 0.15 m and the force was 1500 N is 10000.

The spring constant, k, is a measure of the spring's stiffness. It varies depending on the spring and material. The greater the spring constant, the stiffer the spring and more difficult to stretch.

The letter k symbolizes the "spring constant," which is a number that tells us how "stiff" a spring is.

If k is large, it means that more force is required to stretch it a certain length than would be required to stretch a less stiff spring the same length.

We know that,

F = k(x)

Where k is the spring constant.

Here, it is given that:

F = 1500N

x = 0.15m

So,

1500 = k (0.15)

k (0.15) = 1500

k = 1500/0.15

k = 150000/15

k = 10000

Thus, the value of spring constant is 10000.

The power used when a 100 N force is applied to move an object through a distance of 5 m at constant speed in 10 seconds is 50 W

We'll begin by calculating the energy. This can be obtained as follow:

Force (F) = 100 N

Distance (s) = 5 m

E = F × s

E = 100 × 5

Finally, we shall determine the power. This can be obtained as follow:

Energy (E) = 500 J

Time (t) = 10 s

[tex]P = \frac{E}{t}\\\\P = \frac{500}{10}[/tex]

Therefore, the power used in moving the object is 50 W.

Explanation:

We know that;

P= IV

Where;

P = power

I= current

V = voltage

Here, we have a voltage of 220V

Hence, for maximum rate;

P= IV

I = P/V

P = 840 W

V= 220 V

I= 840 W/220 V

I= 3.8 A

V = IR

R = V/I

R = 220/3.8

R = 57.9 Ω

For minimum heating;

P= 360 W

V= 220 V

I = P/V

I = 360 W/220V

I= 1.6 A

V= IR

R = V/I

R = 220 V/1.6 A

R = 137.5 Ω

Explanation:

Since they got connected it should be the same.

the temperature of the front pipe compare with the temperature of the back pipe before the pipes touch by using same temperature.

Temperature is the measure of hotness or coldness expressed in terms of any of several arbitrary scales and it indicate the direction in which heat energy will spontaneously flow from a hotter body to a colder body.

It is not the equivalent of the energy of a thermodynamic system like burning match is at a much higher temperature than an iceberg whereas the total heat energy contained in an iceberg.

Temperature which is similar to pressure or density known as intensive property  that is independent of the quantity of matter is considered as distinguished from extensive properties, such as mass or volume.

Answer:

Energy can be transferred from one storage mechanism to another.

Answer:

Given that - R = 6 ohm

V = 3 volt

n = ?

so by ohms law , V = I X R

I = V \ R = 3 \ 6 = 0.5 A

we know that I = Q / T here t is 1 sec

Q = I X T = 0.5 X 1 = 0.5 C

By the law of quantization ,

Q = n x e

n = Q / e = 0.5 / 1.6 x 10 ^-19

n = 0.3125 x 10^19

Answer:

the  spring constant is -89.2857 n/m

Explanation:

The computation of the spring constant is shown below:

As we know that

Force in newtons = Spring constant × amount of extension

F = -k × x

where

F = 25 N

And, x = 0.280m

So, the spring constant would 2  

= 25N ÷ 0.280 m

= -89.2857 n/m

Hence the  spring constant is -89.2857 n/m

Answer:

Explanation:

In parallel circuits the current splits up so each branch has a different effective resistance (in each of the separate branches one can use the series rule again). Due to this, the current isn't the same everywhere in a parallel circuit.

(a)

The change in the internal energy will be:

⇒  [tex]\Delta V=\frac{3}{2}nR(\Delta T)[/tex]

Throughout the isothermal procedure, The temperature will be constant "ΔT = 0".

then,

⇒  [tex]\Delta V = \frac{3}{2}nR(0)[/tex]

⇒  [tex]\Delta V = 0 \ J[/tex]

(b)

As we know,

⇒  [tex]\Delta V = Q-W[/tex]

On substituting the value, we get

⇒      [tex]0=Q-W[/tex]

On adding W both sides, we get

⇒    [tex]W=Q-W+W[/tex]

⇒    [tex]W=Q[/tex]

On substituting the given value of "W", we get

Answer:

Workdone = 17482.36 Joules

Explanation:

Given the following data;

Force, F = 120 N

Angle, d = 28.0°

Distance, x = 165 m

To find the work done, we would use the following formula;

Workdone = FxCosd

Substituting into the formula, we have;

Workdone = 120*165*Cos(28)

Workdone = 19800 * 0.8830

Workdone = 17482.36 Joules
