Calculate the turtle’s velocity during the following time intervals: 0-2

Answer: A

Explanation:

The speed of the spaceship  moving around a planet only by the gravitational force  is 7.12 × 10³ m/s.

A fictitious force that moves in a circle and is directed away from the center of the circle is called centrifugal force. When measurements are taken in an inertial frame of reference, the force does not exist. It only becomes relevant when we switch from a ground/inertial reference frame to a rotating reference frame.

The centrifugal force's unit is newton.

As the gravitational force is balanced by centrifugal force is orbital motion:

Gravitational force =centrifugal force

GMm/r² = mv²/r

v² = GM/r

v = √( GM/r)

= √(6.67×10⁻¹¹ ×4.76  ×10²⁶/6.27 ×10⁸)

= 7.12 × 10³ m/s.

Hence, The speed of the spaceship  is 7.12 × 10³ m/s. Hence, option (A) is correct.

Answer:

A transistor works when the electrons and the holes start moving across the two junctions between the n-type and p-type silicon. ... By turning a small input current into a large output current, the transistor acts like an amplifier. But it also acts like a switch at the same time.

Explanation:

force called friction

The force applied to object to stop its motion is known as frictional force.

Newton's first law of motion states that an object in a state of rest or uniform motion in a straight line, we continue in that form unless it is acted upon by an external force. This reluctance of an object to move or stop moving is known as the object's inertia. This inertia depends on the mass of the object.

When an object is finally in motion, the friction, between the object and the surface on which it is moving tends to limit the motion.

Thus, to stop an object in motion, we increase the frictional force between the object and the surface on which the object is moving

Explanation:

i dont have a lot of context but this is what i thought of so...

Stars and planets form when dust and gas from space is pulled together by gravitation.

In mechanics, gravity, often known as gravitation, is the force of attraction that acts on all matter. It has little impact on determining the intrinsic characteristics of common stuff because it is by far the weakest known force in nature.

In contrast, it governs the formations and evolution of stars, galaxies, and the entire cosmos by its extensive and ubiquitous action, which affects the trajectories of objects in the solar system and beyond the universe. All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass.

Hence, the stars and planets form when dust and gas from space is pulled together by gravitation.

Answer:

(a). The speed of the airplane is 78.53 m/s.

(b). The centripetal acceleration 1.234 m/s².

Explanation:

Given that,

Radius = 5000 m

Time = 400 second

We need to calculate the speed of the airplane

Using formula of speed

[tex]v=\dfrac{d}{t}[/tex]

[tex]v= \dfrac{2\pi r}{t}[/tex]

Put the value into the formula

[tex]v=\dfrac{2\times\pi\times5000}{400}[/tex]

[tex]v=78.53\ m/s[/tex]

We need to calculate the centripetal acceleration

Using formula formula

[tex]a=\dfrac{v^2}{r}[/tex]

Put the value into the formula

[tex]a=\dfrac{78.53^2}{5000}[/tex]

[tex]a=1.234\ m/s^2[/tex]

Hence, (a). The speed of the airplane is 78.53 m/s.

(b). The centripetal acceleration 1.234 m/s².

Feather, Biscuit, a 1st grader, Elephant is order of  LEAST inertia to MOST inertia.

Inertia is the resistance of an object to any change in motion. Inertia is proportional the mass of the object: in fact, as we experience in common situations, the larger the mass of an object, the more difficult it is to change its motion.

Inertia of an object is its inherited property. It is the measure of its mass. It is clear that the inertia of an object depends directly on its mass. Mass of an object is the amount of matter contained in it. It is same at every location.

Given that in the case four thing Biscuit, Feather, Elephant, a 1st grader out of which Feather, Biscuit, a 1st grader, Elephant is order of  LEAST inertia to MOST inertia.

Answer:

It will cost $20.81

Explanation:

Cost of Electricity

The rate of the cost of electricity is usually expressed in $/KWH because the consumption of electricity is measured in Kilowatts-hour.

If a 25W porch light is on day and night for a full year, the electricity consumption is:

25W*24 H/Day*365 Day/year* 1 year=219,000 WH

converting to KWH: 219,000 WH = 219,000 /1000 KWH = 219 KWH

The rate is $0.095/KWH, thus:

The cost of electricity is 219 KWH*$0.095/KWH= $20.81

It will cost $20.81

a = v ² / R

where a is acceleration, v is speed, and R is the radius. So

v ² = (7.5 m/s²) / (1.2 m)

v ≈ 6.8 m/s

Answer:

D. Newton's first law is sometimes called the relative inertia law.

Explanation:

Newton's first law of motion states that an object at rest will stay at rest and that in motion will stay in motion with same speed and in the same direction unless an unbalanced force acts on it. It is also called the law inertia. Mass and inertia play a role in this law because mass is a quantity that mainly depends on inertia in that a body with more inertial will exhibit more mass.

Answer:

115.7g

Explanation:

Given parameters:

    Volume of copper  = 100cm³

    Mass of copper  = 890g

Unknown:

Mass of 13cm³ copper  = ?

Solution:

We know that the two materials are both made up of copper. Since we know the mass and volume of the first one, let us solve for the density. Using the density of the first one, we can determine the mass of the second one by the given volume.

Density is an intrinsic property of matter. It has the same value for every given substance.

It is expressed as mass per volume of  a substance;

    Density  = [tex]\frac{mass}{volume}[/tex]

Input the parameters and solve;

  Density  = [tex]\frac{890}{100}[/tex]  = 8.9g/cm³

Now to find the mass of the 13cm³ copper;

       Mass  = density x volume

       Mass  = 8.9 x 13  = 115.7g
