Answer:
infiltration decreases and runoff increase
Explanation:
The changes in surface water movement which is likely to occur when vegetation is removed from the side of a hill is infiltration decreases and runoff increases.
What is surface overflow?Surface overflow is the flow of water which take place on the surface of the ground. The extra water due to rain or flood arises on the ground or at the surface, flows in the nearby lacks or ponds.
Now if the vegetation is removed, great amount of water started to come from the hills. The result of it, more water started to overflow on the land of the surface. This way the runoff increases.
Infiltration is the way by which the ground level water enters into the soil of the earth.
Now, if the vegetation is removed, a lot of amounts of water started to come from the hills. This excess amount of water does not enter in to the soil of the earth.
The changes in surface water movement which is likely to occur when vegetation is removed from the side of a hill is infiltration decreases and runoff increases.

An electric iron consumes energy at a rate of 840 W when heating is at the maximum rate and 360 W when the heating is at the minimum. The voltage is 220 V. What are the current and the resistance in each case?
Don't spam
Answer:
See Explanation
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
A 100 N force is applied to move an object a horizontal distance of 5 meters at constant speed in 10 seconds. How much power is done?
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
Energy (E) =?E = F × s
E = 100 × 5
E = 500 JFinally, we shall determine the power. This can be obtained as follow:
Energy (E) = 500 J
Time (t) = 10 s
Power (P) =?[tex]P = \frac{E}{t}\\\\P = \frac{500}{10}[/tex]
P = 50 WTherefore, the power used in moving the object is 50 W.

A 25 N force stretches a spring 0.280 m. What was the spring constant?
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

Question 2
True or false. In a parallel circuit the current remains the same everywhere.
A.False
B. True
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.

When a 6 Ω resistor is connected across the terminals of a 3 V battery, the number of coulombs passing through the resistor per second is
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

A force of 120 N is applied to the front of a sledge at an angle of 28.00 above the horizontal so as to pull the sledge a distance of 165 meters. How much work was done by the applied force?
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

An ideal gas expands isothermally performing 4.30 x 10³ of work in the process. Calculate (a)
the change in internal energy of the gas, and (b) the heat absorbed during this expansion.
Answer:
The solution of the given query is explained below in the explanation portion.
Explanation:
Given value is:
Work,
⇒ [tex]W=4.30\times 10^3 \ J[/tex]
(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
⇒ [tex]Q=4.30\times 10^3 \ J[/tex]
A spring is stretched 0.15 m and the force was 1500 N. What is the spring constant?
The spring constant for a spring is stretched 0.15 m and the force was 1500 N is 10000.
What is spring constant?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.

How does the temperature of the front pipe compare with the temperature of the back pipe before the pipes touch? What will happen after the pipes have been touching for a while?
Answer:
They become the same exact tempature
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.
what is 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.
