Pressure = ?Solution :-
As per the provided information in the given question, we have been given that Force is 10000 Newton , Area is given 200 meter² . And, we have been asked to calculate the Pressure exerted on the Ground .
For calculating the Pressure , we will use the Formula :-
Pressure = Force / AreaTherefore , by Substituting the given values in the above Formula :-
⇒ Pressure = Force / Area
⇒ Pressure = 10000 / 200
⇒ Pressure = 50
Hence :-
Pressure = 50 Pascals .[tex] \underline {\rule {180pt} {4pt}} [/tex]
Answer:
50 Pa
Explanation:
Here,
→Force(F)=10000N
→Area(A)=200m²
As we have,
→Pressure=Force/Area
→Pressure=10000N/200m²
→Pressure=50 Pa
What effect does wind and water have on mountains?
Answer:
Gale force winds, lightning strikes, temperature extremes and a deluge of snow, hail or rain. These combined forces break up the rocks and erode the peaks into their stark, sculpted forms. Falling ice, rocks and gushing water wear away at the mountain slopes.
describe how an earth wire acts as a safety feature
Answer :
The earth wire is a safety device that is attached to the appliance's casing. If the live wire falls loose and hits the casing, the earth wire offers a conduit for the electrical current to pass. The high current flowing through the ground line melts the fuse, turning off the device. If there is no earth wire, we will be the least resistance path for the current to ground in the event of a fault (shock), as there is no other way for the fault current to dissipate. In the event that there is an earth wire. Because the earth line is the least resistance path to the ground, we will be unaffected.

Azad, of mass 21 kg, is riding a 5.9 kg bike with a velocity of 4.5 m/s to the north- west. a. What is the total momentum of Azad and the bike together? b. What is the momentum of Azad? c. What is the momentum of the bike?
Answer:
a.) Total Momentum = 121 Kg•m/s
b.) Momentum of Azad = 94.5 Kg•m/s
c.) Momentum of Bike = 26.5 Kg•m/s
Explanation:
Given;Mass of Azad = 21 KgMass of bike = 5.9 KgVelocity = 4.5 m/sTo Find;The total momentum of Azad and the bike together = ?The momentum of Azad = ?The momentum of the bike = ?Formula;The product of mass and velocity is called momentum.P = mvNow,
For Azad;Mass of Azad = 21 Kg
Velocity = 4.5 m/s
P = 21 Kg × 4.5 m/s
P = 94.5 Kg•m/s
For Bike;Mass of bike = 5.9 Kg
Velocity = 4.5 m/s
P = 5.9 Kg × 4.5 m/s
P = 26.5 Kg•m/s
For Total Momentum;Total Momentum = Momentum of Azad + Momentum of Bike
Total Momentum = 94.5 + 26.5 = 121 Kg•m/s

an object of 98 N weight is dropped from 10 m height and it hit ground with a speed of 12 m/s find air friction
vf²=vi²+2ad
12²=0+2.a.10
a = 7.2 m/s²
W = m.g
m = W/g = 98/9.8 = 10 kg
∑F=m.a
W-fr=m.a
fr(air friction)=W - m.a
fr = 98 - 10 x 7.2
fr = 98 - 72
fr = 26 N
A 60 kg ice-skater, travelling initially at 3.0 m / s, glides across a horizontal icy surface. The skater brakes and comes to rest after 5.0 m.
The work done against the braking force is the change in the kinetic energy of the skater
Answer:
54 N
Explanation:
a= v/t
3÷5/3= 1.8 m/s^2
f=ma
1.8 x 60 = 108/2 = 54 N

Binaural fusion is the process in which the brain processes information from each ear and creates two different perceptions of the location of sound. Please select the best answer from the choices provided T F.
The statement is true. Binaural fusion is the process in which the brain processes information from each ear and creates two different perceptions of the location of the sound.
What is Binaural fusion?Binaural fusion, also known as binaural integration, is a cognitive process in which different auditory information is delivered binaurally, or to each ear separately.
This mechanism is critical in human speech comprehension because one ear may take up more information about speech stimuli than the other.
Yes, the brain processes the information from both ears, but it only uses the tiny difference among them to produce one sense of where a sound is coming from.
Hence the statement is true.

The acceleration of free fall on a certain planet is 8.0 m s-2. An object gets dropped from a
height and hits the ground after 1.5 s. From what height must the object have been dropped?
We are given that:
The acceleration of free fall on a certain planet is 8m/s². An object is dropped from the height and hits the ground after 1.5sWe need to find:
Height from which the object was dropped.Using equations of motion:
➙ v² - u² = 2as
➙ v = u + at
here,
u = initial velocityv = final velocitya = accelerations = displacementt = time taken Solution:From the given information, we can conclude that:
initial velocity of the object is 0 m/sacceleration due to gravity = 8 m/s²time taken = 1.5 secondsNow, using equation of motion:
➝ v = u + at
➝ v = 0 + ( 8 × 1.5 )
➝ v = 0 + 12 .0
➝ v = 12 m/s
final velocity of object = 12 m/sFor, acceleration :
➝ v² - u² = 2as
➝ ( 12 )² - ( 0 )² = 2 × 8 × s
➝ 144 - 0 = 16s
➝ 16 s = 144
➝ s = 144 / 16
➝ s = 9m
Displacement = 9 m[tex] \dag[/tex] Since, we take displacement in terms of distance in some places, therefore we can say that the height from which the object was dropped is 9 meters .
