Answer: 99.1 seconds

Explanation: You know that the total distance is 34km, and the speed of the sound is 343m/s.

Now, the total time that takes to something with a given velocity, to reach a distance D, is:

T = D/v

where D = 34km and v = 343m/s

Now, here we have different units, so we must convert the kilomeres into meters, this can be done as: 1km = 1000m then, 34km = 1000*34m = 34000m

Then the total time is:

T = 34000m/343m/s = 99.1 seconds

Answer:

99 s

Explanation:

distance = rate × time

34000 m = (343 m/s) t

t = 99 s

A block of wood has density 0.500 g/cm3 and mass 2 000 g. It floats in a container of oil (the oil's density is 0.750 g/cm3). Wh
Gennadij [26K]

Answer:

2,666.67cm^3

Explanation:

All we need to do in this problem is divide the mass of the wooden block to the oil's density.

2000/0.750 ≈ 2,666.67cm^3

Best of Luck!

20 POINTS WILL BE MARK BRAINLIEST<br><br> ATTACHED BELOW GAS LAW WORKSHEET
german

Explanation:

I will do two of each as examples.

Boyle's law says that at constant temperature, the product of the initial pressure and volume equals the product of the final pressure and volume.

1. P₁ V₁ = P₂ V₂

(1.5 atm) (10.0 L) = (0.75 atm) V

V = 20.0 L

2. P₁ V₁ = P₂ V₂

(100.0 kPa) (500.0 mL) = P (1,000.0 mL)

P = 50.0 kPa

Charles' law says that at constant pressure, the quotient of the initial volume and temperature equals the quotient of the final volume and temperature.

6. V₁ / T₁ = V₂ / T₂

(10.0 L) / (1500 K) = V / (750 K)

V = 5.0 L

7. V₁ / T₁ = V₂ / T₂

(500.0 mL) / (100 K) = (1000.0 mL) / T

T = 200 K

A basketball has a mass of 601 g. Moving to the right and heading downward at an angle of 29 degree to the vertical, it hits the
olga55 [171]

Answer:

Change in momentum, \Delta p=6.3\ kg-m/s

Explanation:

It is given that,

Mass of the basketball, m = 601 g = 0.601 kg

The basketball makes an angle of 29 degrees to the vertical, it hits the floor with a speed, v = 6 m/s

It bounces up with the same speed, again moving to the right at an angle of 29 degree to the vertical. We need to find the change in momentum. It is given by :

\Delta p=mv\ cos\theta-(-mv\ cos\theta)

\Delta p=2mv\ cos\theta

\Delta p=2\times 0.601\times 6\times \ cos(29)

\Delta p=6.3\ kg-m/s

So, the change in momentum of the basketball is 6.3 kg-m/s. Hence, this is the required solution.
