Answer: 0.0208 Centuries

Explanation:

There is 2.739*10^-5 centuries per 1 day.

We can take 746 days and multiply it by that 2.7 number to get how many centuries are in 746 days.

[tex]746 *(2.793*10^{-5})[/tex] = 0.0208 centuries

Answer:

150N

force= 150N

Answer:

v = 10 m/s

Explanation:

We have,

Our initial velocity is 20 m/s

Our acceleration, [tex]a=-5\ m/s^2[/tex]

It is required to find the velocity after 2 seconds. It is a concept based on equation of kinematics. Using first equation:

[tex]v=u+at[/tex]

Plugging all the known values

[tex]v=20+(-5)(2)\\\\v=10\ m/s[/tex]

So, our final velocity is 10 m/s.

Answer:

Condenser

Explanation:

The refrigerator work on a simple cycle:

1- When the cold air inside the refrigerator starts to get warm, it loses its thermal energy ot the cold refrigerant which is flowing inside an evaporator. This thermal energy converts the refrigerant into a gas.

2- The refrigerant, in a form of gas, goes to the compressor. The compressor compresses it and increases its temperature even more.

3- Then it goes to the condenser where it loses its most of the thermal energy to the condenser coils. When it loses the energy. it comes back to liquid form.

4.The refrigerant flow back to the evaporator

Answer:

are in equal size or act in same direction

Balanced forces are the forces which are equal in size. Balanced force has a net force which is equal to zero, and these do not cause a change in motion. Thus, the correct option is C.

Balanced forces are those which are opposite in direction and equal in the size. Balanced forces are considered to be in the state of equilibrium. When the forces are balanced and there is no change in direction. Combined forces which are balanced are always equal to zero. These forces are equal and hence do not cause any change in the motion of an object.

Examples of balanced forces include resting against a wall, lying down, aircraft in a steady-flight, floating in water, and standing in the ground.

Therefore, the correct option is C.

Answer:Answer:

They are inhaled or eaten

Explanation:

Radioactivity can be defined as the process in which an unstable atomic nucleus spontaneously emits ionizing radiation and charge particles. This eventually results in the formation of an energetically stable atomic nucleus.

Examples of radioactive elements are Uranium, Polonium, Thorium, Radon, etc. The radiation emitted during this process is classified as;

1. Alpha radiation (α).

2. Beta radiation (β).

3. Gamma radiation (G).

Alpha-emitting substances, such as radon gas, can be a serious health hazard only if they are inhaled or eaten. Alpha-emitting substances compared to other radiation has very short-range particle and as such cannot penetrate the human skin or body.

Answer:

The travels is 9.3 and displacement of 4.3 meters

Explanation:

The computation of distance and displacement is shown below:-

Distance = Northward meters + Southward meters

= 2.5 meters + 6.8 meters

= 9.3 meters

Displacement= Final - Initial distance

= 6.8 meters - 2.5  meters

= 4.3 meters

Direction→southward

Here direction is going towards the southwards as southwards distance in higher than the northward distance of displacement is southward.

answer is 4

Explanation:

The charge that is moved is required.

The magnitude of charge moved is option 4. [tex]2\times 10^{-3}\ \text{C}[/tex]

V = Potential difference = 10.0 V

W = Work done = [tex]2\times10^{-2}\ \text{J}[/tex]

q = Magnitude of charge

When work done on moving a charge is divided by the potential difference we get the magnitude of the charge that is moved.

The charge of an object is the result of an excess or a lack of positive or negative charges on a body.

So, the magnitude of charge is given by

[tex]q=\dfrac{W}{V}\\\Rightarrow q=\dfrac{2\times 10^{-2}}{10}\\\Rightarrow q=2\times 10^{-3}\ \text{C}[/tex]

Explanation:

The most likely effect of Mrs. Williams' comment on Susan's test performance was that the reduced performance due to stereotype threat. Thus, the correct option is C.

Stereotype threat is a situational predicament in which the people feel themselves to be at risk or are actually at risk of conforming to the stereotypes about their social group in the community. It is theorized to be a contributing factor to the long-standing racial and gender gaps in the academic performance of a community as a whole.

The worst part of stereotype threat would be that it becomes socially acceptable for the people to agree and think that it is true of that segment of the society. This has been the tool of tyrants and tyrannical regimes to divide and conquer since the down of empires.

Centripetal Force Requirement

The Forbidden F-Word

Mathematics of Circular Motion

As mentioned earlier in this lesson, an object moving in a circle is experiencing an acceleration. Even if moving around the perimeter of the circle with a constant speed, there is still a change in velocity and subsequently an acceleration. This acceleration is directed towards the center of the circle. And in accord with Newton's second law of motion, an object which experiences an acceleration must also be experiencing a net force. The direction of the net force is in the same direction as the acceleration. So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration. This is sometimes referred to as the centripetal force requirement. The word centripetal (not to be confused with the F-word centrifugal) means center seeking. For object's moving in circular motion, there is a net force acting towards the center which causes the object to seek the center.

To understand the importance of a centripetal force, it is important to have a sturdy understanding of the Newton's first law of motion - the law of inertia. The law of inertia states that ...

... objects in motion tend to stay in motion with the same speed and the same direction unless acted upon by an unbalanced force.

According to Newton's first law of motion, it is the natural tendency of all moving objects to continue in motion in the same direction that they are moving ... unless some form of unbalanced force acts upon the object to deviate its motion from its straight-line path. Moving objects will tend to naturally travel in straight lines; an unbalanced force is only required to cause it to turn. Thus, the presence of an unbalanced force is required for objects to move in circles.

Answer:

Acceleration = 0

Explanation:

Uniform Velocity = 1.5m/s

Acceleration is defined as the change in Velocity of a moving object with time.

Acceleration = (V2 - V1) / t

Where v2 and V1 are velocities and t is time

A body is said to be moving at a uniform Velocity if the Velocity with which it moves is constant. That is there is no change in the Velocity as the body progresses

Mathematically ;

(V2 - V1) = 0 [uniform / constant Velocity]

acceleration = 0 / time

Acceleration = 0

The answer is D  (1/5)m/s^2

Answer: 10m/s^2

Explanation:

Given the following :

Initial Velocity(U) = 10m/s

Angle of inclination = 30°

In other to calculate the magnitude of the vector,

We need to resolve into verti AL and horizontal component.

Vertical component of a vector(Uy) = U × Sinθ

Horizontal component(Ux) = U × Cosθ

Uy = 10 × sin30 = 10 × 0.5 = 5m/s

Ux = 10 × Cos30 = 10 × 0.866 = 8.66m/s

Therefore the magnitude equals :

U = √(Uy)^2 + (Ux)^2

U = √5^2 + 8.66^2

U = √25 + 74.9956

U = √99.9956

U = 9.9997799

U = 10m/s^2
