If you see fog, what can you know about the temperature and dewpoint near the ground? (Just a simple-ish, short answer please.)
Answer:The difference between air temperature and dew point is less than 4.5 degrees Fahrenheit when fog can form.
Explanation:This can occur because of added moisture or falling air temperatures. The difference between air temperature and dew point is less than 4.5 degrees Fahrenheit when fog forms.

Select one:
a. Tech A
b. Tech B
c. Both A and B
d. Neither A nor B
The statements made by the two technicians with respect to a process control module (PCM) are both correct: c. Both A and B.
What is PCM?PCM is an abbreviattion for process control module and it can be defined as a system that comprises a group of sensors, actuators, and other artificially intelligent processing equipment, which is operated as a single entity in an industry while providing its users (technicians) a desired result or response.
This ultimately implies that, a process control module (PCM) is designed and developed to do the folloing:
Perform basic self-diagnostics on the components in the system.Learn from its actions.Make better decisions in the future based on prior information.In conclusion, we can deduce that the statements made by the two technicians with respect to a process control module (PCM) are both correct.

4. Find the number of electrons transferred between two points kept at a potential difference of 20 V if 40 J of work is done
Required answer :-
Number of electrons transferred are 1.25 × 10^19Given :-
V = 20 Volt W = 40 JWe know that,
↠ W = P × t
↠ W = V × I × t
↠ W = V × Q/t × t
↠ W = V × Q
On substituting values, we get
↠ 40 = 20 × Q
↠ Q = 40/20
↠ Q = 2 c
↠ ne = q
↠ n = q/e
↠ n = 2/ 1.6 × 10^- 19
↠ n = 1.25 × 10^19
Hence,
Number of electrons transferred are 1.25 × 10^19If 2 waves collide with each other, would they cancel out, or merge?
Answer:
It depends on the velocity, if 1 wave is going faster than the other, it could eat the other wave and thus: Merge.
If they are the same speed they would cancel out, it would be like 2 trucks hitting each other.
Explanation:
If 2 waves crash at 15mph they would splash back and fall into the water. Think about boxers.
Answer: Destructive interference occurs when waves come together in such a way that they completely cancel each other out. When two waves interfere destructively, they must have the same amplitude in opposite directions.

Light with a wavelength of about 490 nm is made to pass through a diffraction grating. the angle formed between the path of the incident light and the diffracted light is 9.2° and forms a first-order bright band. what is the number of lines per mm in the diffraction grating? round your answer to the nearest whole number. lines per mm
The number of lines per mm in the diffraction grating is 326.
What is diffraction grating?A diffraction grating is a type of optical instrument obtained with a continuous pattern. The pattern of the diffracted light by a grating depends on the structure and number of elements present.
The given data in the problem is
[tex]\rm \theta[/tex] is the angle formed between the path of the incident light and the diffracted light = 9. 2°
λ is the wavelength of the light=490nm=4.9
N is the number of lines per mm in the diffraction grating=?
n is ordered = 1
The formula for the diffraction grating is;
[tex]n \lambda = d sin\theta \\\\ d = \frac{n \lambda}{sin \theta } \\\\ d = \frac{1 \times 4.90 \times 10^{-7}}{sin 9.2^0 } \\\\ d=3.06 \times 10^{-6} \\\\ d=3.06 \times 10^{-3} \ mm[/tex]
The number of lines per mm is found as;
[tex]\rm N= \frac{1}{d} \\\\ N= \frac{1}{3.06 \TIMES 10^{-3}} \\\\ N=326.8 /mm[/tex]
Hence the number of lines per mm in the diffraction grating is 326.

Explanation:
A golf club exerts an average force of 500N on a 0.1kg golf ball and the contact time is 0.01s.
What is the change in velocity of the golf ball?
Answer:
[tex]50\; {\rm m\cdot s^{-1}}[/tex], assuming that the force on the golf ball was constant.
Explanation:
Assume that the force the golf club exerted on the golf ball a constant force of magnitude [tex]F[/tex]. Let [tex]\Delta t[/tex] denote the duration the club was in contact with the golf ball. The impulse of this force would be:
[tex]J = F\, \Delta t[/tex].
Let [tex]\Delta p[/tex] denote the change in the momentum of this golf ball. By the impulse-momentum theorem, this [tex]\Delta p\![/tex] would be equal to the impulse on the golf ball.
[tex]\Delta p = J = F\, \Delta t[/tex].
The momentum [tex]p[/tex] of this golf ball is the scalar product between the mass [tex]m[/tex] of this golf ball and the velocity [tex]v[/tex] of this golf ball. The mass of this golf ball stays the same. Thus, when the momentum of this golf ball changes by [tex]\Delta p[/tex], the velocity of this golf ball would change by [tex](\Delta p) / (m)[/tex].
The change in the velocity of this golf ball would thus be:
[tex]\begin{aligned}\Delta v &= \frac{\Delta p}{m} & \genfrac{}{}{0em}{}{(\text{change in momentum})}{}\\ &= \frac{J}{m} & \genfrac{}{}{0em}{}{(\text{impulse on the golf ball})}{}\\ &= \frac{F\, \Delta t}{m} \\ &= \frac{500\; {\rm N} \times 0.01\; {\rm s}}{0.1\; {\rm kg}} \\ &\approx 50\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].
(Note that [tex]1\; {\rm N} = 1\; {\rm kg \cdot m^{2}\cdot s^{-2}}[/tex].)

radiation from which type of decay has the least energy
Answer:
Alpha decay is the least penetrating. This is because the Alpha particle produced during the decay process is relatively large and low in energy thus it is easily 'blocked' and does not travel far through space.
Explanation:
Two forces, F1 = -3000 N and F2 = +1500 N acts on a plane horizontally. The craft is moving with a constant velocity of -850 m/s. A third force F3 is also present in the scenario but is not indicated in the image below. Find the magnitude and direction of F3
Because the net force must be zero, we conclude that the magnitude of the force is 1500 newtons, and the direction is in the positive axis.
What is the magnitude and direction of the third force?
By Newton's laws, we know that if the net force applied to an object is different than zero, then the object is accelerated.
In this case, we know that the object moves with constant velocity, so there is no acceleration, meaning that the net force is equal to zero.
Then we must have:
F1 + F2 + F3 = 0N
Replacing F1 and F2 we get:
-3000 N + 1500N + F3 = 0
F3 = 3000N - 1500 N = 1500N
Then the magnitude of the force is 1500 newtons, and the direction is in the positive axis.

an object from 10.0 meters. She knows it had 50.0 joules of potential energy. How much mass does it have?
Answer:
5N
Explanation:
Work done by a constant force is given by the following equation:
W=F⋅d⋅cos(θ)
where F is the applied force, d is the distance over which the force is applied, and θ is the angle between the force and displacement vectors.
In this case, the work is done by gravity, and as the object is assumed to fall straight down, θ=0^o.
We know that the force of gravity acting on an object can be expressed by FG=mg, and for an object which is not accelerating (e.g. a stationary object), this is equal to the object's weight.
We know d=10m,θ=0^o and W=50J, so we can solve for F to find the object's weight. ⇒F=Wdcos (θ) But cos (0^o)=1, so: F=Wd=50J10m=5N
A police car is asked to overtake a red sedan that is 16 km ahead of it on the freeway. The red sedan is traveling at 80 km/hr and the police car travels at 100 km/hr. When will the police car overtake the sedan?
Answer:
S = v0 t + 1/2 a t^2 a = 0 seems given in the problem
Vp t = Vr t + 16
both travel for time t but the police car is going faster and travels 16 km farther
t (Vp - Vr) = 16
t = 16 km / (100 - 80) km/hr
t = 16 / 20 hr = 4/5 hr = 48 min
