GREYUIT [131]

Answer:

1066.67 m

Explanation:

Given:

v₀ = 96 km/h = 26.67 m/s

v = 48 km/h = 13.33 m/s

Δx = 800 m

Find: a

v² = v₀² + 2aΔx

(13.33 m/s)² = (26.67 m/s)² + 2a (800 m)

a = -0.333 m/s²

Given:

v₀ = 26.67 m/s

v = 0 m/s

a = -0.333 m/s²

Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (26.67 m/s)² + 2 (-0.333 m/s²) Δx

Δx = 1066.67 m

Round as needed.

The volume in the pump when the pump piston is all the way down represents the _______
sveticcg [70]

The volume in the pump when the pump piston is all the way down represents the end systolic volume.

<h3>What is systolic volume?</h3>

End systolic volume is the volume of blood in a ventricle at the end of contraction, or systole, and the beginning of filling, or diastole.

End systolic volume is the lowest volume of blood in the ventricle at any point in the cardiac cycle.

Thus, the volume in the pump when the pump piston is all the way down represents the end systolic volume.

Which of these is not a standard unit?<br> a. second <br> b. metre<br> c. hand span <br> d. gram
Leto [7]

Answer:  Hand span

Explanation: Hand span is not a standard unit.

Second is the unit of time.

Meter is the unit of length or distance covered by an object.

Gram is the unit of weight of an object.

Hand span is not a standard unit. This is because the size of hand varies from person to person. Hence, the correct option is (c) "hand span".

A planet has two moons with identical mass. Moon 1 is in a circular orbit of radius r. Moon 2 is in a circular orbit of radius 2
saw5 [17]

Answer:

Half as large.

Explanation:

Using Newton's law of universal gravitation, if the mass of the planet is <em>M</em> and of the Moons 1 and 2 is <em>m</em>, them the force exerted by the planet on them will be:

F_1=\frac{GMm}{r}

F_2=\frac{GMm}{2r}

Which clearly shows that the force that the planet exerts on the Moon 2 is half  the force it exerts on the Moon 1.
