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

We have that the sea level pressure for Leh area is 1150mb mathematically given as

Ps= 1150 mb

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.

Therefore,  here for the sea level pressure we need to add,

Ps=800+350

Ps= 1150 mb

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

Explanation:

The forces acting on the rock include Normal Force, Gravitational force & Friction force

It's possible for it to stay on the boulder because the normal force balances it's weight. also because static friction acts on the boulder up to it's limiting friction even if it were on an attempt to move as a result of air resistance. gravitational forces act upon it by mainly affecting it it's weight. as altitude increases, it's weight decreases since gravity varies from a height to another.

This is the correct answer

The  magnitude of the electric field strength at that position  is 2.6×10⁴ Newton/Coulomb.

An electric field is a physical field that surrounds electrically charged particles and acts as an attractor or repellent to all other charged particles in the vicinity. It can also refer to a system of charged particles' physical field. Electric charges and time-varying electric currents are the building blocks of electric fields.

Given parameters:

Charge of the point charge: Q = 4.2 × 10⁻⁶ Coulomb.

Distance of the position from the position: r = 1.2 meter.

The  magnitude of the electric field strength at that position = kQ/r²

= 9 × 10⁹ × 4.2×10⁻⁶/(1.2)² Newton/coulomb.

= 2.6×10⁴ Newton/Coulomb.

Hence, the  magnitude of the electric field strength at that position  is 2.6×10⁴ Newton/Coulomb.

So, the force of gravity that the asteroid and the planet have on each other approximately [tex] \boxed{\sf{2.9 \times 10^{17} \: N}} [/tex]

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 :

[tex] \boxed{\sf{\bold{F = G \times \frac{m_1 \times m_2}{r^2}}}} [/tex]

With the following condition :

We know that :

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

If amplitudes are equal, high frequency waves carry more energy than low frequency waves.

When the force is applied normal to the circumference at point P, then it's zero.

It should be noted that force simply means an influence that can change the position of an object.

In this case, when the force is applied normal to the circumference at point P, then it's zero.

Also, if the force is applied normal to the circumference at point X, then it's constant.
