This statement about perception is true.

perceive: the input from our environment, sight, sound, taste, touch, temperature…we perceive the external inputs and process them to the best of our conscious abilities.

You mention thinking. Let's broaden that out a bit. Call it conceive: the internal abilities we both process perception and create with. Thinking, emotions, imagination, curiosity, learning, organizing, even fear are all conceiving attributes. This is the wonder and the horror of our species. We are homo sapiens. We are aware of ourselves, all that we perceive we and all that we conceive. More than thinking, much more. Be well.

perception involves the senses, whereas thought involves reasoning.

However, these two categories overlap, since they cannot function

apart, but only together. (As Kant quipped, “intuition without concepts

To finish the electromagnet, connect the copper wire's exposed ends to the opposing battery connections. A magnetic field is produced by current passing via the wire coiled around the nail.

A loose electron is drawn to a proton to become neutral if an electron moves to the wire. Lack of electrons can result from pushing electrons from out their orbits. Electric current is the name given to the constantly moving electrons in wire.

Electrons are moving constantly in current electricity. Direct current (DC) and dc voltage (AC) are the two types of current used in electricity (AC). Electrons move only in the direction of direct current. Direct current is produced by batteries. The resistance to potential difference ratio determines the current. It is displayed as (I). I = V/R is the formula currently in use.

If the distance between the objects is increased, the new force would be 1N

The term gravitational force has to do with the force that acts between two masses that are on the earth's service.

Now we know that the force that acts on the object can be given by;

F = Gm1m2/r^2

F = force that acts on the object

G = gravitational constant

m1 and m2 = masses of the objects

r = distance about

We can now see that the force that acts on the object would be 1 N.

A. Centripetal force acting on the two stars is the reason why the two stars will not crash into one another

B. The mass of each stars, given they maintain a constant distance of 8×10¹⁰ m is 7.68×10²⁷ Kg

A. Why don't the two stars crash into one another?

Centripetal force is the force that acts to keep an object moving in a circle. Since the two stars undergoes revolution, this means they rotate in a circle. Thus, centripetal force is acting on them.

Therefore, we can say that the two stars will not crash into one another due to the centripetal force

B. How do I determine the mass of each stars?

We can obtain the mass of each stars as illustrated below:

F = GM₁M₂ / r²

Note: They rotate mid-way. Thus distance apart (r) = 2r

F = GM₁M₂ / (2r)²

F = GM₁M₂ / 4r²

Also, centripetal force is given as:

F = mv² / r

Thus, we have:

mv² / r = GM₁M₂ / 4r²

But

v = 2πr / T

v² = (2πr / T)² = 4π²r² / T²

M₁ = M₂ = m

Thus, we have

m4π²r² / rT² = Gmm / 4r²

4π²r / T² = Gm / 4r²

Cross multiply

mGT² = 4r² × 4π²r

mGT² = 16π²r³

Divide both sides by GT²

m = 16π²r³ / GT²

From the question given, we have:

m = 16π²r³ / GT²

m = [16 × 3.14² × (8×10¹⁰)³] / [6.67×10¯¹¹ × (3.97×10⁸)²]

m = 7.68×10²⁷ Kg

Thus, the mass of each stars is 7.68×10²⁷ Kg

The maximum quantity per inner package or article for shipping risky commodities in limited quantities is the limited quantity exception.

The term "limited quantity" could refer to a specific object that is only available in a limited number or to a sort of resource that is only available in a limited amount. A limited amount often refers to an item's limited availability, such as a limited edition item or a product with a limited supply. If you are exporting small amounts of dangerous items, you may be eligible for a Limited Quantity Exemption. This exception is a simpler regulatory option to fully regulate all DG shipments. If your goods are eligible for this exemption, a number greater than zero will appear in the column "Limited Quantity Index." Even if dangerous commodities are carried in restricted or acceptable quantities, there are still packing and labeling standards that must be met.

Answer:

B. 29.75 meters

Explanation:

Distance = speed x time

Distance = 3.5 x 8.5

Distance = 29.75 m/s

From the peak of the tower, it will fall 92.2 meters to the ground.

Vi(vertical) = 0;

h = 60 m;

h = Vi*t + 1/2g*t2;

60 = 0; t = 60/5;

time = 12; t = sqrt(12) seconds;

t = 3.5 seconds.

Vi(horizontal)=20 m/s

20 m/s remains constant since there is no force opposing it in the horizontal direction.

70 meters are equal to 20 m/s times 3.5 seconds in range.

70 meters from the tower's base, the ball will land on the ground.

distance from the tower's summit is equal to sqrt(702+602)

= sqrt(4900 + 3600), or 92.2 meters.

From the peak of the tower, it will fall 92.2 meters to the ground.

The correct free body diagram for the case when the ball is at its lowest point is tension pointing upwards and weight of the object pointing downwards.

The tension in the string at the lowest point in a circular path is equal to weight added to centripetal force required.

Mathematically, the formula for the tension in the string is given as;

T = W + ma

where;

At the lowest point the acceleration of the object is zero, a = 0. The new equation becomes the following;

T = W

The free body diagram of the tension and the weight of the object is given as;

The coefficient of volume expansion of the liquid, βliquid is 2.24 * 10⁻⁴ (C°)⁻¹.

The coefficient of volume expansion of the liquid is determined as follows:

Let the initial volume of the object be V₀

The change in the volume of the object will be ΔV

The expression for the change in the volume of the object when the temperature of the object changes by ΔT is:

ΔV = βV₀ΔT

where;

β is the coefficient of volume expansion

The data provided is as follows;

The initial volume of liquid and aluminum can, V₀ = 7.0 * 10⁻⁴ m³

The coefficient of volume expansion for aluminum = 69 x 10⁻⁶ (C°)⁻¹

The volume of liquid that spilled out, ΔV = 7.8 * 10⁻⁶ m³

Change in temperature, ΔT = (78 - 6)°C

ΔT = 72 °C

The difference between the change in volume of the liquid and the can is equal to the amount of liquid that spilled out.

ΔV = (βV₀ΔT)liquid - (βV₀ΔT)can

βliquid = ΔV/V₀ΔT + βcan

βliquid = (7.8 * 10⁻⁶ m³) / (7.0 * 10⁻⁴ m³ * 72 °C) + 69 x 10⁻⁶ (C°)⁻¹

The normal force exerted by the chair on us, when we sit on the chair.

When an object interacts with another object, it feels a push or a pull. Each object that two objects make contact with experiences a force. Once the encounter is over, the force between the two objects is gone. Forces are merely interactions; they do not exist independently.

When two objects interact and appear to be in physical contact with one another, contact forces are generated. Several types of contact forces include frictional forces, tensional forces, normal forces, air resistance forces, and applied forces. Even when two interacting objects are far apart from one another, action-at-a-distance forces are still present.

Oceanic plates are described as plates that are located beneath the ocean. As the name implies, oceanic plates are denser than continental ones, the reason is that because they are made of denser rocks. Oceanic plates are typically composed of basalt.

Oceanic plates are formed from mantle material at midocean ridges.

The young oceanic lithosphere is hot and buoyant having low density when it forms at a midocean ridge. But as it spreads away from the ridge and cools and contracts becoming more denser it is able to sink into the hotter underlying mantle.
