Which of the following are scalar quantities?

kirill [66]

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

Approximately how many atoms are there along a 9.5 cm line

uranmaximum [27]

First convert 5.5 cm to meters.

(5.5 cm / 1) x (m / 100 cm) = 0.055 m

A typical atom is about 1.0E-10 m in diameter; thus:

0.055 m / 1.0E-10 m = 5.5E8 atoms or 550,000,000 end-to-end atoms in 5.5 cm

Two identical loudspeakers 2.30 m apart are emitting sound waves into a room where the speed of sound is 340 m/s. Abby is standi

Dimas [21]

Answer:

Abby is standing (4.5^2 + 2.3^2)^1/2 from the far speaker

D2 = 5.05 m from the far speaker

The difference in distances from the speakers is

5.05 - 4.5 = .55 m (Let y be wavelength, lambda)

n y = 4.5

(n + 1) y = 5.05 for the speakers to be in phase at smallest wavelength

y = .55 m subtracting equations

f = v / y = 340 / .55 = 618 / sec should be the smallest frequency

A projectile is fired with initial speed vo at an angle of 45o above the horizontal. Assume no air resistance.

katrin2010 [14]

Answer:

The correct answer is a

Explanation:

At projectile launch speeds are

X axis vₓ = v₀ = cte

Y axis $v_{y}$ = v_{oy} –gt

The moment is defined as

p = mv

For the x axis

pₓ = mvₓ = m v₀ₓ

As the speed is constant the moment is constant

For the y axis

p_{y} = m v_{y} = m (v_{oy} –gt) = m v_{oy} - m (gt)

Speed changes over time, so the moment also changes over time

Let's examine the answer

i True

ii False. The moment changes with time

The correct answer is a
