Answer:

humidity is 80.95 %

Explanation:

given data

humidity = 44% = 0.44

temperature = 20.0°C

temperature = 10.0°C

to find out

relative humidity

solution

we know humidity formula that is

humidity = \frac{vapor density}{saturated vapor density} × 100   ...................1

so here at 20.0°C

vapor density is

vapor density = humidity × saturated vapor density

here

saturated vapor density at 20.0°C is  17.3 gm/m³

so

vapor density = 0.44 × 17.3

vapor density = 7.61

and

for 10.0°C  

saturated vapor density at 10.0°C is  9.4 gm/m³

so from equation 1

humidity = \frac{vapor density}{saturated vapor density} × 100  

humidity = \frac{7.61}{9.4} × 100  

humidity = 80.95 %

A rocket ship has several engines and thrusters. While the Solid Rocket Booster (SRB) and main engines only work together during
Katarina [22]

A rocket ship is accelerated by the SRB and the main engines for 2.0 minutes and the main engines for 8.5 minutes after the launch. The acceleration of the ship during the first 2.0 minutes is 11 m/s² (D).

A rocket ship has several engines and thrusters. We can divide its initial movement into 2 parts:

  • From t = 0 min to t = 2.0 min, the SRB and the main engines act together and the speed goes from 0 m/s (rest) to 1341 m/s.
  • From t = 2.0 min to t = 8.5 min, the main engines alone accelerate the ship form 1341 m/s to 7600 m/s.

We want to know the acceleration in the first part (first 2.0 minutes). We need to consider that:

  • The speed increases from 0 m/s to 1341 m/s.
  • The time elpased is 2.0 min.
  • 1 min = 60 s.

The acceleration of the ship during the first 2.0 minutes is:

a = \frac{\Delta v }{t} ) \frac{(1341m/s-0m/s)}{2.0min} \times \frac{1min}{60s}  = 11 m/s^{2}

A rocket ship is accelerated by the SRB and the main engines for 2.0 minutes and the main engines for 8.5 minutes after the launch. The acceleration of the ship during the first 2.0 minutes is 11 m/s² (D).

3. Identify three elements and three compounds. How are they<br> similar? How are they different?
Basile [38]

Answer:  A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of.

Allushta [10]

Answer:

143

Explanation:

Using one of the 3 fundamental equations in physics, y=vo*t+1/2gt^2, we can use this equation to find the total distance that was traveled.

Acceleration due to gravity is always 9.8m/s^2 and time is 5.4s, we also have no initial velocity.

Given this, we can plug in the known variables.

y=0t+1/2*9.8*5^2

simplify,

y=4.9*5.4^2

y=4.9*29.16

y=142.884m which we can round up to 143 meters

Final Answer: 143 meters
