Answer:

*The same balloon put into the freezer would be smaller and shriveled.

* The volume decreases as the temperature decreases.

* using a hypothetical starting volume of 2 liters in the balloon at 42 degrees Celsius, we can use the equation V1/T1 =V2/T2

V2= 1.54 liters which proves when temperature decreases , volume decreases as well.

Explanation:

The volume increases as the temperature increases, and volume decreases as the temperature decreases.

using a hypothetical starting volume of 2 liters in the balloon at 42 degrees Celsius, we can use the equation V1/T1 =V2/T2

Change Celsius to kelvin by adding 273.

2 liters/ 315 K = V2/243 K

Cross multiply and then divide by 315 to find V2

2 liters x 243 K / 315 K = V2

The Kelvin cancels itself out.

486 liters /315=V2

V2= 1.54 liters.

This proves that when the temperature decreases , so does the volume.

Suppose you increase your walking speed from 6 m/s to 14 m/s in a period of 2 s. What is your acceleration? m/s2
saveliy_v [14]
4.5m/s you count the number between 6 and 14 and get 9 do 9 divided by 2 and you get 4.5 m/s increase. hope this helps.

Which principle explains why the flame bends toward the wind?
kondaur [170]
Bernoulli principle
According to Bernoulli's principle, this faster moving air on the top has a lower pressure than the non-moving air on the bottom. With a greater pressure on the bottom of the paper there is also a greater force pushing up.

Calculate the acceleration of a bus whose speed changes from 7 m/s to 16 m/s over a period of 5 s.
Bezzdna [24]
Let’s do this together!

Okay so the acceleration formula is vf-vi over time .

So the initial velocity (vi) 7m/s final velocity (vf) is 16m/s so we’re going to subtract 16-7 which is 9
M/s

So the time is 5s so 9m/s divided into 5s is 1.8m/s/2

So the answer is 1.8m\s2

Suppose you give a 10 Newton push to Ryan on skis (he weighs 50 kg), how much will he accelerate?
Talja [164]

Well we can just use F=ma. The force is 10N, the mass is 50 kg, solve for a. Well since we kg and N, no conversion is necessary. So just plugging in the numbers, we get

10N = 50 kg · a

\frac{10N}{50kg}=a

A newton is just \frac{kg·m}{s^{2}}

a=\frac{\frac{10kg·m}{s^{2}}}{50kg}

The s^2 and 50 kg you multiply

a=\frac{10kg·m}{50kg·s^{2}}

The kg's cancel and 10/50 is 1/5

\frac{1}{5}·\frac{m}{s^{2}}

So the acceleration is 1/5 m/s^2
