The distance of point where gravitational acceleration a due to earth is 1/10 of its value from surface is  7436.8km.

We know that value of acceleration due to gravity at surface of earth is given by the formula g=GM/r²

where G is the earth's gravitational constant, M is the mass of earth and r is the distance between center and surface of earth.

Now,when we consider a point outside the surface of earth as h then value of acceleration due to gravity is =GM / (r+h)²

Now,we are given that value of acceleration due to gravity is 1/10 to the value at surface

∴GM / (r+h)²=(1/10) × (GM/r²)

=>r²/(r+h)² = 1/10

=>r/(r+h)=  √(1/10)

=>r/(r+h)= 1/√10

On further solving,we get

=>√10 ×r=r+h

=>r×(√10-1)=h

Since this point is from center of earth and we need to find point from surface,there distance of point is =h-r=r×(√10-1)-r=r×(√10-2)=1.162r

Now,we know that radius of earth is 6400km

So,on putting =1.162r=1.162×6400=7436.8Km

Hence,distance of point from surface of earth is 7436.8km.

The scientific concept that the student most likely used to arrive at his conclusion is Newton's laws of motion.

Newton's Laws of motion - Newton's Laws of motion consists of 3 important Laws. The three laws of motion help us understand how objects behave when standing still, when moving and when forces act upon them.

according to Newton's 2nd laws:

F = ma (where m is mass and a is acceleration of the object)

the subject applied same force on both the balls, but the ball 2 travelled greater distance.

F = M1a1

M1 = F/a1

and M2 = F/a2

and S = 1/2at2 if initial velocity is 0.

so, S is directly proportional to a

so, M1 = F/S1

and M2 = F/S2

Since, S2 is greater than S1, so M2 is less than M1 because distance is inversely proportional to mass of the object.

The net force on the sled is 400 N.

The net force on the sled is the sum of all the forces acting on the sled. In this case, the only forces acting on the sled are the horizontal force of 200 N applied by the athlete and the force of friction acting on the sled.

The force of friction is given by the equation:

F_friction = μ × F_normal

where F_friction is the force of friction, μ is the coefficient of friction between the sled and the surface it is on, and F_normal is the normal force acting on the sled.

The normal force is the force exerted on an object by a surface that is perpendicular to the surface. For an object at rest, the normal force is equal to the weight of the object. In this case, the weight of the sled is 50 kg × 9.8 m/s² = 490 N.

Plugging the values for the coefficient of friction, the normal force, and the applied force into the equation gives us the following:

F_friction = μ × F_normal = μ × 490 N = 200 N

The net force on the sled is the sum of the horizontal force applied by the athlete and the force of friction:

F_net = F_horizontal + F_friction = 200 N + 200 N = 400 N

Therefore, the net force on the sled is 400 N.

Diffraction of light, as it is used to describe light, occurs more explicitly when a light wave passes by a corner or via an opening or slit that is physically smaller than the wavelength of that light, if not even smaller.

The intensity pattern that appears on the lit screen is determined by the superposition principle. When the difference in pathways from the two slits to a location on the screen equals an integral number of wavelengths (0,, 2,...), constructive interference takes place.

The kinetic energy relies on the mass since the speed is constant.

Then,Therefore, the ratio of the kinetic energies of A and B is 1: 2.

As a result, we can say that puck B has kinetic energy that is twice that of puck A.

The puck's final speed is specified as,

H = v^2 * (sinθ)^2 / 2g

H = (40)^2 * (sinθ)^2 / 2g

H = 1600 *  (sinθ)^2 / 2g

Cross multiply
