A car starts from rest and accelerates at 9 m/s². After 240 m. the final speed is 66 m/s.

Uniformly Accelerated Motion is the motion of an object where the acceleration is constant.

A car starts from rest, that is, its initial speed is 0 m/s. It accelerates at 9 m/s². We can find the final speed after 240 m using the following kinematic equation.

v² = u² + 2 × a × s

v² = (0 m/s)² + 2 × (9 m/s²) × 240 m

v = 66 m/s

where,

Answer:

5 m/s2

Explanation:

Using the equation velocity = initial velocity + (acceleration x time)

30 m/s = 0 + acceleration x 6 s

30 m/s = 6 s x acceleration

30 m/s / 6s = acceleration

acceleration = 5 m/s2

You are riding your bike at 5 m/s. In order to avoid hitting a child that has run into the street, you slam on your brakes and slow to a stop. It takes you  1.5 seconds to fully stop. Acceleration will be  3.33 [tex]m/s^{2}[/tex]

The branch of physics that defines motion with respect to space and time, ignoring the cause of that motion, is known as kinematics. Kinematics equations are a set of equations that can derive an unknown aspect of a body’s motion if the other aspects are provided.

given

speed = 5 m/s

time = 1.5 seconds

using

v = u + at

0 = 5 + a ( 1.5 )

a = -5 / 1.5

 = 3.33 [tex]m/s^{2}[/tex]

Acceleration will be  3.33 [tex]m/s^{2}[/tex]

Explanation:

Friction is the force that opposes motion.

The term friction refers to the force that hinders the movement of a surface over another. The frictional force depends on the nature of the surfaces in contact.

1) The two forces acting on the ball during the frictional force are the forward force and the frictional force.

2) The ball takes more time to roll down the incline in the presence of the cloth because of the increase in friction of the surface.

3) The students repeated the investigation there times in order to ensure accuracy of the results.

4) The energy of the ball changes from potential energy at the top of the ramp to kinetic energy as it rolls down the ramp.

The tension in the coupling between the second and third cars is 269,730 N.

Since the weight of each car is the same, the applied force on each will be the same and the tension on the coupling between the cars will be the same.

T = F = ma

T = 9(37,000 x 0.81)

T = 269,730 N

Thus, the tension in the coupling between the second and third cars is 269,730 N.

C) end Q attracts both X and Y

Reason: The metal bar PQ is magnetized and has magnetic properties in it, that's I why the point Q is pointing towards the north. The XY bar doesnt point towards any specific direction because it isn't magnetized and doesn't have magnetic properties in it, and that's why it gets attracted by Q and it's both ends.

The number of valance electrons in the given Bohr Diagram is 7 electrons each.

Bohr diagrams depict electrons orbiting the nucleus of an atom in the same way that planets orbit the sun.

Electrons in the Bohr model are depicted as traveling in circles at different shells depending on the element.

We now know that the Bohr Model has some flaws, but it is still widely used because of its straightforward approach to atomic theory.

The Bohr model was also the first to incorporate quantum theory into an atomic model, making it the forerunner of today's more accurate quantum-mechanical models.

Each valance electron in the given Bohr Diagram has 7 electrons.

Thus, the valance electrons in each of the given diagram is 7 electrons as they have these electrons in their outermost shell.
