Answer:

true..........................

Speed and velocity use the same formula for calculations. However, an object can have a different average speed and average velocity because of displacement. This is true statement.

As a vector quantity with both magnitude and direction, velocity has both. This term refers to the speed at which an object is moving or shifting positions.

Since speed is a scalar quantity, it lacks direction. It indicates the rate of a moving thing. When a particle's speed is high, it indicates that it is travelling quickly, and when it is low, it indicates that it is going slowly.

The displacement of a body during a period of time divided by the passage of time yields the average velocity of the body during that period.

The distance travelled by a body in a given amount of time, divided by the amount of time, is the body's average speed.

Answer:

Speed is constant but velocity is changing

Explanation:

Speed is a scalar quantity, meaning magnitude only. Velocity is a vector quantity, meaning magnitude and direction. If you're moving in a circle at a constant speed, the speed is constant but the direction is constantly changing. Therefore, the speed is constant but velocity changes.

We are given:

Mass of Neptune = 1.03 * 10²⁶ kg

Distance from the center of Neptune (r) = 2.27 * 10⁷

now, computing the value of the acceleration due to gravity (g)

Finding g:

We know the formula:

g = G(mass of planet) / (r)²

g = [6.67 * 10⁻¹¹ * 1.03*10²⁶] / (2.27*10⁷)                      [since G is 6.67*10⁻¹¹]

g = (6.87 * 10¹⁵) / (5.15 * 10¹⁴)

which can be rewritten as:

g = (6.87 * 10¹⁵ * 10⁻¹⁴) / 5.15

g = (6.87 * 10¹⁵⁻¹⁴) / 5.15

g = (6.87/5.15) * 10

g = 1.34 * 10

g = 13.4 m/s² (approx)

Given that,

Mass of a skier, m = 55 kg

The vertical distance between start and finish is 10 m.

(a) The potential energy of a skier is given by :

[tex]E=mgh\\\\E=55\times 9.8\times 10\\\\=5390\ J[/tex]

(b) When she reaches the bottom of the hill, the potential energy is converted to kinetic energy. So,

[tex]5390=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2\times 5390}{55}} \\\\v=14\ m/s[/tex]

Hence, her potential energy is 5390 J and at the bottom of the hill she is moving with a speed of 14 m/s.

Oxygen is more chemically reactive than nitrogen because Oxygen needs to gain only 2 electrons to have a full octet, while nitrogen needs to gain 3. The correct option is A.

The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.

Valence electrons are the electrons present in the outermost shell of an atom. They can easily be determined by the number of valence electrons in an atom by looking at the specific group in the periodic table.

The fewer number of electrons in the valance shell, the more reactive is the element.

Oxygen needs to gain only 2 electrons to have a full octet, while nitrogen needs to gain 3.

Thus, Oxygen is more chemically reactive than nitrogen.

Then the correct option is A.

Answer:

80m/s

Explanation:

to find it you have to work it out by using the formula distance divided by speed to find time.

The time taken by the skateboarder to reach the bottom 120m away is 80 sec.

Acceleration may be defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities as it has both magnitude and direction.

When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing. If an object is speeding up and moving in a positive direction, it has a positive acceleration.

According to the question,

Speed of the skateboarder = 1.5 m/s

The total distance needs to be traveled = 120m

Total time taken =?

The Formula for calculating time is as follows:

Therefore, the time taken by the skateboarder to reach the bottom 120m away is 80 sec.

A possible value for the force of static friction when  Jamie applied 75.1 Newtons of force on the box is 75.1N. Option B is correct.

For the box sitting on a horizontal surface, the formula for calculating the force on the box along the horizontal based on Newton's law is expressed as;

Since the forces acting along the horizontal are the frictional force and moving force, the formula above will become;

Since the body is static, hence [tex]a_x=0m/s^2[/tex], the equation becomes;

Given the force Jamie apply on the box to be 75.1Newtons, this shows that the moving force is 75.1N. Hence;

Explanation:

m = Massa balok

g = Percepatan gravitasi

[tex]\theta[/tex] = Sudut kemiringan
