How do you convey your emotion in text communication?
Hey there! Hope this answer helps.
Answer:
Emojis: Emojis are a useful way to convey human emotions due to their human characteristics; they mimic the expressions of the human face, they serve as simple shorthand for conveying an emotional state without directly stating it :)Punctuation: Not only for clarity, but different uses of punctuation can be convey different things - e.g. exclamation marks (!) can express anger, emphasis, sadness or delight depending on the context, and full stops (.) or periods in the US are interpreted as bold, assertive or aggressive. On the same note, texters find sentences with no period or with ellipses more passive or open ended and formalLength: Think about it like this: "I read about your relative's passing on Insta-gram and am sorry for your loss" likely has more emotional impact than "read abt ur family's passing on ins-ta, sry 4 ur loss."- profparis
If in the figure below, the friction between the block and the incline is negligible, (a) how much must the object on the right weigh if the 200-N block is to remain at rest?

The magnitude of the acceleration and its direction however depends on the resultant force.
What is the resultant force?
In a system of forces, the resultant force is the force that has the same effect in magnitude and direction as all the forces acting together.
In an inclined plane, the friction, weight and applied force all act together on the object. The magnitude of the acceleration and its direction however depends on the resultant force.
This question is incomplete as the diagrams are missing hence the numerical values can not be computed.

1. Describe the three Newton's Law of Motion.
Answer:
1st law--Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The key point here is that if there is no net forceacting on an object (if all the external forces cancel each other out) then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. If an external force is applied, the velocity will change because of the force.
2nd— The second law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum(mass times velocity) per change in time. Newton also developed the calculus of mathematics, and the "changes" expressed in the second law are most accurately defined in differential forms. (Calculus can also be used to determine the velocity and location variations experienced by an object subjected to an external force.) For an object with a constant mass m, the second law states that the force F is the product of an object's mass and its acceleration a:
F = m * a
For an external applied force, the change in velocity depends on the mass of the object. A force will cause a change in velocity; and likewise, a change in velocity will generate a force. The equation works both ways.
3rd law-- The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A. Notice that the forces are exerted on different objects. The third law can be used to explain the generation of lift by a wing and the production of thrust by a jet engine.
A body with an initial velocity of 4m/s accelerates uniformly at the rate of 1.2 m/s² over a distance of 20 m. Calculate: (i) the final velocity of the body.(ii) the time in which the body covers that distance. (iii) the average velocity of the body during the journey
v² = u² + 2as
v² = 4² + 2 × 1.2 × 20
v² = 16 + 2 × 12/10 × 20
v² = 16 + 48
v² = 64
v = 8 ms - 1
So,the final velocity is 8 m/sii)
V = u + at
8 = 4 + 1.2 × t
8 - 4 = 1.2t
4 = 12/10 t
4 × 10 /12 = t
3.33 = t

A few friends went skating on the frozen lake in their hometown. At one point you can hear the ice cracking. What advice can you give them so that the ice does not break and the skaters on the lake are not endangered?
Answer: i'll tell them to be careful. However, the most common is using a drill bit. Take a step close to the shore and listen for cracking. If there is cracking, do not risk going out on the ice. If there is no cracking, take a cordless drill and check the thickness using an extended drill bit.

What factors affect the strength and direction of electrical forces?
Answer:
The strength of the electric field is determined by the amount of charge on the source charge (Q) and the separation distance (d) from the source charge.
Explanation:
The interaction of charged objects is a non-contact force that operates over a certain separation distance. Distance, distance, distance. Every electrical contact is accompanied by a force, emphasizing the significance of these three factors. Whether it's a plastic golf tube attracting paper bits, two like-charged balloons repelling, or a charged Styrofoam plate interacting with electrons in a piece of metal, the three crucial factors that impact the strength of the interaction are always two charges and a distance between them. The electrical force, like all other forces, is usually measured in Newtons. The electrical interaction's intensity is a vector quantity with both magnitude and direction since it is a force. The electrical force's direction is determined by whether the charged objects are charged with similar or opposing charges, as well as their spatial orientation. With a little logic and knowledge of the two objects' charge types, the direction of the force on either of them may be determined. Objects A and B in the figure below have similar charges, hence they repel each other.

If a constant force of 917 N is exerted on a scooter for 6 s, thenwhat is the change in momentum?
a 6 kg-m/s
b 5502 kg-m/s
c 917 kg-m/s
d 153 kg-m/s
Answer: 917
Explanation:
The change in momentum if a constant force of 917 N is exerted on a scooter for 6s is 5502kg-m/s.
How to calculate momentum?Momentum is the tendency of a body to maintain its inertial motion. It is the product of its mass and velocity, or the vector sum of the products of its masses and velocities.
Force = mass x (velocity/time)
Force = (mass x velocity)/time
Force = momentum/time
According to this question, a constant force of 917 N is exerted on a scooter for 6s. The change in momentum is calculated as follows:
917N = p/6
p = 5502kg-m/s
Therefore, 5502kg-m/s is the change in momentum of the scooter.

Sonar is used to determine the speed of an object. A 40 kHz signal is sent out, and a 42 kHz signal is returned. Assume the speed of sound is 345 m/s. How fast is the object moving?
Sonar is used to determine the speed of an object. The object is moving at 8.4146 m/s.
What is frequency?The frequency of any wave is defined as the number of cycles per second.
The frequency of the sound received is
f' = f x [(V+Vo /V-Vo)]
where f = 40kHz, f' = 42kHz, V =345 m/s, then the velocity of the observer will be
(V+Vo /V-Vo) = 42/40 =1.05
On rearranging the doppler shift formula, we have
Vo = 0.05 x 345 /2.05
Vo = 8.4146 m/s.
Thus, the object is moving at 8.4146 m/s.

Explanation:
a
The bottle weighs 80g with tablets
If the bottle alone weighs 23g, the tablets weigh 57g
100 tablets weigh 57g, 1 tablet weighs 0.57g
b
0.57g is one tablet, so to achieve 36 tablets we must multiply by 36
0.57 multiplied by 36 is 20.52
c
To find 50 tablets we can use the same method we used before or a slightly faster method
100 tablets is 57g, so all we have to do is halve to find 50
57 divided by 2 is 28.5
