Answer:

9.86m/s

Explanation:

let's get to the formula

kinetic energy = 1/2*m*v^2= .5*1140*(13.6)^2=105427.2 j

it looses 50k j of energy. so new energy = 105427.2-50000 = 554227.2

again use the formula for k.e

ans = 9.86 m/s

Question 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.

Answer:

C

Explanation:

Basically force is given by the formula.

F= ma

Where m is mass of the body and 'a' is acceleration.

Here the time is not given, hence it is not possible to calculate acceleration, as acceleration is given by the formula

a= v/t

So most probably the question is wrong.

However if we take acceleration= 2m/s^2

Then F= ma= 50*2= 100N

However if the question was to find energy then it is sufficient to find kinetic energy as moving objects possess kinetic energy.kinetic energy is given by the formula:

KE= 1/2*m* v^2

I.e, KE= 1/2 * 50 * 2* 2

Hi ! Now, I will help to discuss about the gravitational force between two objects. The force of gravity is not affected by the radius of an object, but radius between two object. Moreover, if the object is a planet, the radius of the planet is only to calculate the "gravitational acceleration" on the planet itself,does not determine the gravitational force between the two planets. For the gravitational force between two objects, it can be calculated using the following formula :

Hi there!

Recall the following:

[tex]V \text{ (Electric Potential Energy) } = \frac{kq_1q_2}{r}\\\\F_E = \frac{kq_1q_2}{r^2}[/tex]

k = Coulomb's Constant (Jm/C²)

q = Charge (C)
r = distance between charges (m)

To calculate the electric force between the two charges, we can simply divide by another 'r' (distance):

[tex]F_E = \frac{70}{0.049} = \boxed{1428.57 \mu J}[/tex]

Take "to the right" to be the positive direction. By conservation of momentum,

m₁v₁ + m₂v₂ = m₁(v')₁ + m₂(v')₂

where the v-s denote initial velocities and the v'-s denote final velocities. m₁ and m₂ are of course masses, but we're told that m₁ = m₂, so we can eliminate these factors altogether:

v₁ + v₂ = (v')₁ + (v')₂

We're given that v₁ = +4.0 m/s, (v₁)' = -1.5 m/s, and (v')₂ = +4.0 m/s.

Solve for v₂ :

v₁ + v₂ = (v')₁ + (v')₂

4.0 m/s + v₂ = -1.5 m/s + 4.0 m/s

⇒   v₂ = -1.5 m/s

In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other, while strain is the measure of the deformation of the material.

Strain energy density functions (W) establish the relation between the amount of energy employed to deform a volume unit of a solid and imposed strain.

Explanation:

Stress, strain and strain-energy density is discussed below.

In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed

Out of all the largest x component is of Vector C of value 150i and Vector B will have highest y component of value 173j

Vectors are objects which have both, magnitude and direction. Magnitude defines the size of the vector. It is represented by a line with an arrow, where the length of the line is the magnitude of the vector and the arrow shows the direction.

Vector A = direction is in y direction = 100j

Since , this vector is only in y direction and have no component in x direction , so its x component will be = 0i

Vector B = direction is at angle of 60.0 degrees above the +x axis  

Resolving into x and y components

x component = Vector B*cos(60) = Vector B * (1/2) = Vector B /2 = 200 /2

                                                                                                           = 100i

y component = Vector B * sin(60) = Vector B  * [tex]\sqrt{3}[/tex]/2  = 173j

Vector C = direction is along the +x axis

hence , it will not have any y component

x component = 150i

y component = 0j

Out of all the largest x component is of Vector C of value 150i and Vector B will have highest y component of value 173j
