Take left to be the negative direction, and right to be positive. That means the forces on the squirrel would be -2N and 3N.
Add all the forces to find the net force on the squirrel. -2N+3N=1N
Because the positive direction is to the right, the net force of 1N is directed to the right.
<span>The complete question is:
</span><span>If a liquid is sealed in a container and kept at constant temperature, how does its vapor pressure change
</span>a. it continues to steadily increase
<span>b. it increases at first, then remains constant </span>
<span>c. it increaees at first, then decreases </span>
<span>d. it continues to steadily decrease
</span>
I believe the correct answer is option B. The vapor pressure change would be that it increases at first, then remains constant. <span>More particles escape the liquid and go into the vapor phase at first. But eventually, the number of escaping particles equals the number of particles going back into the liquid.</span>
Answer:
or 0.32 μm.
Explanation:
Given:
The radiations are UV radiation.
The frequency of the radiations absorbed (f) =
The wavelength of the radiations absorbed (λ) = ?
We know that, the speed of ultraviolet radiations is same as speed of light.
So, speed of UV radiation (v) =
Now, we also know that, the speed of the electromagnetic radiation is related to its frequency and wavelength and is given as:
Now, expressing the above equation in terms of wavelength 'λ', we have:
Now, plug in the given values and solve for 'λ'. This gives,
Therefore, the wavelength of the radiations absorbed by the ozone is nearly or 0.32 μm.
The answer is true it is because when yielding, it is advisable that the driver of the vehicle to slow down, when it is safe to pass through, oncoming intersection, and to be aware of vehicles that are oncoming. It allows vehicles to move ahead by giving them the right of way for yielding enables the driver to slow down and give them the way especially with oncoming vehicles.
