Answer:

B)zonal function

Explanation:

To sum the values in individual pixels in a multi-layered raster data set we use

zonal function.

As we know that zonal function use zone statics to sum the individual pixels.A zone can be defined as the area where all input will have same values.These areas should not meet . Feature and raster data sets can be used for as a input for zone function.

Irina-Kira [14]

Answer:

100.11 m

Explanation:

Given:

Coefficient of volume expansion, $\alpha_{v}=33\times10^{-6}$ /°C.

Initial length of rod, $l=100 m$

Change in temperature, ΔT= $(90-(-10))=100$ °C

We know that,

$\alpha_{v}=3\alpha_{L}\\\alpha_{L}=\frac{\alpha_{v}}{3}\\\alpha_{L}=\frac{33\times10^{-6}}{3}=11\times10^{-6}$ /°C

Here, $\alpha_{L}$ is the coefficient of linear expansion.

Now, we know that,

Change in length (Δl) is given as,

$\Delta l=\alpha_L\times L\times\Delta T$

Plug in all the values and solve for $l$ .

This gives,

$\Delta l=11\times10^{-6}\times 100\times100\\\Delta l=0.11 \textrm{ m}$

Therefore, the length of rod after expansion is $L+\Delta l=100+0.11=100.11$ m.

"A proton is placed in a uniform electric field of 2750 N/C. You may want to review (Page) . For related problem-solving tips an

tekilochka [14]

To solve this problem we will start from the definition of Force, as the product between the electric field and the proton charge. Once the force is found, it will be possible to apply Newton's second law, and find the proton acceleration, knowing its mass. Finally, through the linear motion kinematic equation we will find the speed of the proton.

PART A ) For the electrostatic force we have that is equal to

$F=qE$

Here

q= Charge

E = Electric Force

$F=(1.6*10^{-19}C)(2750N/C)$

$F = 4.4*10^{-16}N$

PART B) Rearrange the expression F=ma for the acceleration

$a = \frac{F}{m}$

Here,

a = Acceleration

F = Force

m = Mass

Replacing,

$a = \frac{4.4*10^{-16}N}{1.67*10^{-27}kg}$

$a = 2.635*10^{11}m/s^2$

PART C) Acceleration can be described as the speed change in an instant of time,

$a = \frac{v_f-v_i}{t}$

There is not $v_i$ then

$a = \frac{v_f}{t}$

Rearranging to find the velocity,

$v_f = at$

$v_f = (2.635*10^{11})(1.4*10^{-6})$

$v_f = 3.689*10^{5}m/s$
