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

Answer:

V= 80 cm^3

Explanation:

V= 10 * 4* 2

V= 80 cm^3

It would take 3 hours and 45 minutes, for a plane to fly 1,500 miles if it was moving at a constant speed of 400 miles/hour.

Calculation

where,

r stands for rate or speed (sometimes denoted as v, for velocity)

d is the traveled distance.

t is the amount of time needed to finish the movement.

Explanation:

Given that,

The density of water is 1 g/cm³

The density of ethanol is 0.8 g/cm³

We need to find the volume of the ethanol that has the same mass as 100 cm³ of water.

Density=mass/volume

For water,

[tex]d=\dfrac{m}{V}\\\\m=dV\\\\m=1\ g/cm^3\times 100\ cm^3\\\\m=100\ g[/tex]

For ethanol,

[tex]d=\dfrac{m}{V}\\\\V=\dfrac{m}{d}\\\\V=\dfrac{100\ g}{0.8\ g/cm^3}\\\\V=125\ cm^3[/tex]

Hence, 125 cm³ of ethanol has the same mass as 100 cm³ of water.

Answer:

1.00 g/cm3

Key Equations

Position Vector: `n r (t) = (t)^j+y

Total acceleration: `n a = `n aC

+ `n aT

Position Vector in frame S is the position Vector in frame S` plus the vector from the origin of S to the origin of S`: `n rPS = `n rPS`

+ `n rS`S

Relative velocity equation connecting two references frame: `n vPS = `n vPS`

+ `n vS`S

The average velocity of a car that travels 30 kilometers due west in 0.50 hour - 60 km/hour west.

Average velocity is the displacement of an object with the time change. To find the average speed of an object we divide the distance travelled by the time elapsed.

Average velocity = ∆x/∆t

Then,

average velocity = 30/0.5

= 300/5

= 60

Thus, the correct answer would be - 60 km/hour west.

a) density = 93.6g/12cm³

= 7.8g/cm³

b) The reason is alloying

Explanation:

volume of the rectangular block = l× b × h

= (4 × 2 × 1.5)cm

= 12 cm³

density = mass/ volume

mass = 93.6g

volume = 12cm³

therefore,

density = 93.6g/12cm³

= 7.8g/cm³

Hadley cells

Explanation:

Formation of Convection Currents

Atmospheric convection currents are global patterns of air movement that are initiated by the unequal heating of Earth. Hadley cells- the convection currents that cycle between the equator and 30˚ north and south.

The force of something stronger than the muscles causes it to increase its tension as it gets longer is true.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Frictional force allows the ball to stay in the hand while muscular force is employed to stop the motion of the ball during catching. Throughout this activity, the Earth's gravitational pull on the ball is constant.

The force of something stronger than the muscles causes it to increase its tension as it gets longer is true.

Explanation:

Answer:

A. manipulate the independent variable

1. The property of a conductor by virtue of which it posses the flow of electric current through it is called resistance.

2. The resistance of a conductor depends on the cross sectional area of the conductor and it's resistivity.

3.This id due to the fact that the resistance of a wire is inversely proportional to the square of its diameter.

Answer:

There's no question-

the answer is B your welcome

The  true statement about a series circuit is: the current flow through every part of the circuit is the same. Hence, option (B) is correct.

Electrical networks and two-terminal components can be linked either serially or parallelly. The electrical network that results will have two terminals and be capable of operating in either a series or parallel topology.

It depends on your point of view whether a two-terminal "thing" is an electrical network (like resistors connected in series) or an electrical component (like a resistor). In this article, a two-terminal "thing" that participates in series/parallel networks will be referred to as a "component."

Each component connected in series travels the same "electrical path" and carries the same amount of current—equal to the network's current—through it.
