Answer:
With an increase in temperature, there is typically an increase in the molecular interchange as molecules move faster in higher temperatures. The gas viscosity will increase with temperature. ... With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.
Answer:
<h3>The answer is 8 kg</h3>
Explanation:
The mass of the object can be found by using the formula
![m = \frac{f}{a} \\](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7Bf%7D%7Ba%7D%20%20%5C%5C%20)
f is the force
a is the acceleration
From the question we have
![m = \frac{40}{5} \\](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B40%7D%7B5%7D%20%20%5C%5C%20)
We have the final answer as
<h3>8 kg</h3>
Hope this helps you
Answer:
It's terrifying, but a relief that you know your children isn't home alone.
Explanation:
Why, it's because sometimes you don't know what is going on in the daycare. The baby/ the child you gave birth to is in the hands of a random stranger. It's also a relief knowing that at least someone is taking care of your child, or hope to be. Instead of your child, no adult supervision or any people watching your child can result in death, injuries, and more since your child is alone.
The resultant velocity is 40.3 m/s at 7.1 degrees north of west
Explanation:
Jason's motion is divided into two parts.
At first, he moves west with a speed of
![v_x = 40.0 m/s](https://tex.z-dn.net/?f=v_x%20%3D%2040.0%20m%2Fs)
Then, he moves north with a speed of
![v_y = 5.0 m/s](https://tex.z-dn.net/?f=v_y%20%3D%205.0%20m%2Fs)
The two velocities are at right angle, so they form the sides of a right triangle, and the magnitude of the resultant velocity can be calculated using Pythagorean's theorem:
![v=\sqrt{v_x^2+v_y^2}=\sqrt{40.0^2+5.0^2}=40.3 m/s](https://tex.z-dn.net/?f=v%3D%5Csqrt%7Bv_x%5E2%2Bv_y%5E2%7D%3D%5Csqrt%7B40.0%5E2%2B5.0%5E2%7D%3D40.3%20m%2Fs)
And the direction can be found by using
![\theta = tan^{-1}(\frac{v_y}{v_x})=tan^{-1}(\frac{5.0}{40.0})=7.1^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20tan%5E%7B-1%7D%28%5Cfrac%7Bv_y%7D%7Bv_x%7D%29%3Dtan%5E%7B-1%7D%28%5Cfrac%7B5.0%7D%7B40.0%7D%29%3D7.1%5E%7B%5Ccirc%7D)
So, 7.1 degrees north of west.
