At 3 seconds, the object changes its direction of motion with the equation v = (4.2 m/s) - (1.4 m/s2)t.

The explanation describes the speed of an object and how this speed changes depending on time.

Equation of velocity

V = (4.2 m/s) - (1.4 m/s²)t

When an object changes its direction, it momentarily comes to rest at point B.

V = 0

0 = 4.2 - 1.4 t

t = 4.2 : 1.4 = 3 sec

The half-life of F-18 is 1.8 hours, so after 1.8 hours, half of the original amount of F-18 will remain. After 3.6 hours, a quarter of the original amount will remain, and so on.

At 3:00 PM (9 hours after the F-18 was made), the hospital will have

= approximately 0.03125 milligrams of F-18 remaining.

At midnight (18 hours after the F-18 was made), the hospital will have

The  objects collide together where one object is exerting force on the other in equal and opposite magnitude. When they stuck together, their final momentum will be the sum of initial of momentum  of each object. Thus, the final momentum after collision will be 16 kg m/s.

Momentum is a physical quantity which is equal to the  product of mass and velocity of the object. Hence, for a stationary body, the there will be no momentum.

During collision, the total momentum is conserved. Thus, the sum of initial momentum of the colliding objects is equal to the final momentum of the combined mass.

The momentum of object 1 = 12 Kg m/s

object 2 = 4 kg m/s.

Thus, total initial momentum  = final momentum = 12 + 4 = 16 Kg m/s.

Therefore, the final momentum after collision is 16 Kg m/s.

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

The toy does not approach the spring. Hence, option (A) is correct.

The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction.

Mass of the car-toy: m = 2 kg.

Initial speed of the car-toy: v = 2 m/s.

Distance between the initial position of the car-toy and the spring: d = 3m.

Coefficient of friction: μ = 0.14

Hence, initial kinetic energy of the toy-car = mv²/2 = 2×(2)²/2 Joule = 4 Joule.

Frictional energy loss during approaching from initial position to the spring = μmg·d

= 0.14 × 2 kg × 9.8 m/s² × 3 m

= 8.232 Newton.

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
