We have that the sea level pressure for Leh area is 1150mb mathematically given as
Ps= 1150 mb
Sea level pressureQuestion Parameters:
Ladakh is 800 mb.
assuming that Leh is at an altitude of 3500 m and every 100 m
increase in height with respect to sea level corresponds to 10 mb pressure,
Generally, for 3500m the pressure change will be 350 mb.
Therefore, here for the sea level pressure we need to add,
Ps=800+350
Ps= 1150 mb

What is metric conversion system?The metric conversion system is a standardized system of measurement based on the International System of Units (SI). It is used by scientists, engineers, and many others around the world to ensure consistency and accuracy in measurement.
The system is based on a series of prefixes that can be added to a base unit of measurement to create multiples or fractions of that unit. For example, the prefix "kilo-" means "thousand," so one kilometer is equal to 1,000 meters. The metric system is widely used in scientific and technical fields and is also the official system of measurement for many countries.
To convert inches to meters, we can use the conversion factor 1 inch = 0.0254 meters.
So, the width of the printer in meters is:
18 inches x 0.0254 meters/inch = 0.4572 meters

2. An object’s velocity is measured to be v (t) = αt−βt2, where α = 4.00 m/s2 and β = 2.00 m/s3. Calculate the average acceleration of the object from t = 0.0 s to t = 3.0 s
Hi there!
Given the values for α and β, we can plug these into the given equation:
[tex]v(t) = 4t - 2t^2[/tex]
Begin by solving for the velocity at t = 0 and t = 3:
At t = 0:
[tex]v(0) = 4(0) - 2(0^2) = 0 \frac{m}{s}[/tex]
At t = 3:
[tex]v(3) = 4(3) - 2(3^2) = 12 - 18 = -6 \frac{m}{s}[/tex]
Acceleration is the SLOPE of the velocity graph (its derivative), so we can use the kinematic equation:
[tex]a = \frac{v_f - v_i}{\Delta t}[/tex]
Plug in the knowns:
[tex]a = \frac{-6-0}{3 - 0} = \boxed{-2 \frac{m}{s^2}}[/tex]

If a box that weighs 4.00 N slides across a flat rough table for a distance of 2.00 m then how much work does the weight of the box
do on the box?
A) 88.0 J
B) 456 J
C) 270 J
D) 513 J
E)zero
Answer:
0
Explanation:
Here it's given that the weight of the box is 4N and it slides across a rough table for a distance of 2m . And we are interested in finding out the work done by the weight of the block. Firstly we know that , Work done is ,
[tex]\rm\longrightarrow \pink{ Work\ = \ F.s = |F||s|cos\theta} [/tex]
where
[tex]\theta[/tex] is the angle between displacement and force .Therefore ,
[tex]\rm\longrightarrow Work = (4N)(2m)(cos\theta) [/tex]
Here the angle between the displacement and force is 90° , and value of cos90° is 0 , therefore,
[tex]\rm\longrightarrow Work = 8N-m (0)\\[/tex]
[tex]\rm\longrightarrow \underline{\boxed{\rm\blue{Work = 0 }}}[/tex]
The work done by the weight of the box is zero. The correct answer is zero. The correct option is (E).
Given:
Weight of the box = 4.00 N (acting downward)
Distance = 2.00 m
The angle between force and displacement, θ = 90°
Using the formula for work:
Work (W) = Force × Distance × cos(θ)
Since the angle θ is 90 degrees and cos(90 degrees) = 0.
The work done by the weight of the box is:
W = Force × Distance × cos(90)
W = 4.00 × 2.00 × 0
W = 0 J
Therefore, the work done by the weight of the box is zero. The correct option is (E).

You walk from chisale to st Francis a distance of 6km/h and 50minutes, the average speed in m/s will be 2m/s
What is average speed ?The average speed of a moving object is defined as the total distance covered by it divided by the total time taken.
The S.I unit of speed is meter per second. Speed is also measured in kilometer per hour.
Average speed is a scaler quantity
Average speed is the total distance travelled by an object to the total time taken. However, average velocity is the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs. No matter how many times the speed has been changed to travel the entire distance , average speed is that constant speed value with which one can travel by and reach the same distance in same amount of time .
It can be calculated with a formula average speed = distance / time
given
distance = 6 km = 6000 m
time = 50 minutes = 50 * 60 = 3000 sec
average speed = distance / time
= 6000 / 3000 = 2m/s

A box of spherical jawbreaker candies is 23 g and its volume is 32.3 cm3. If the average mass of a single jawbreaker is 0.94 g, what is the radius of a single jawbreaker
The radius of each jawbreaker is approximately 0.68 cm.
Volume of a sphere;v = 4 /3 πr³where
r = radius
Therefore,
23 g = 32.3 cm³
0.94 g = ?
cross multiply
volume of a single jawbreaker = 32.3 × 0.94 / 23 = 30.362 / 23 = 1.32 cm³
Therefore,
volume of each jawbreaker = 4 /3 πr³
1.32 = 4 / 3 × 3.14 × r³
r³ = 1.32 /4.18666666667
r³ = 0.31533683707
r = ∛0.31533683707

A hiker travels 5.0 km north and then 2.5 km west What is the resultant displacement vector?
Answer: The resultant displacement vector is 5.6km
The resultant displacement vector of the hiker is equal to 5.6 km.
What is displacement?The distance can be described as the total length traveled by an object and is a scalar quantity with only magnitude. The distance should be always positive.
The displacement of an object can be described as the shortest length between two points. The displacement can be considered as a vector quantity with direction & magnitude. The displacement can be +ve, -ve, or zero and can be changed with time.
Given, a hiker moves 5.0 km along AB in the North and then 2.5 km west along BC.
The length (AC) is the resultant displacement that can be calculated by using Pythagoras' theorem:
AC² = AB² + BC²
AC² = (5.0)² + (2.5)²
AC² = 25 + 6.25
AC = 5.59 km ≈ 5.6 km
Therefore, the displacement of the hiker is 5.6 Km.

Answer:
I think that protection of one species can not protect its community.
Explanation:
The advantage of protecting entire ecosystems is the most effective way to save species because species confined to a small area could be wiped out by a single natural disaster. Some species require a large range to find adequate food or mate. Therefore, protecting the habitats of endangered and threatened species often means preserving or managing large areas (entire ecosystem).
