When does an object reach its terminal velocity?
Answer: Terminal velocity is achieved, therefore, when the speed of a moving object is no longer increasing or decreasing; the object's acceleration (or deceleration) is zero.
Explanation:.
Answer: Terminal velocity is achieved, therefore, when the speed of a moving object is no longer increasing or decreasing; the object's acceleration (or deceleration) is zero.
As others have said, 8 seconds to get to 90% of terminal velocity. But if you're falling from outer space, you could reach speeds much higher than terminal velocity, and slow down when you reach the atmosphere. If coming in from a long distance, you'll burn up like a meteorite.

A. Chlorine and bromine
B. Calcium and strontium
C. Nitrogen and phosphorus
D. Argon and krypton
** THE ANSWER IS D **
Answer:
D
Explanation:
their octet is complete they don't react with any thing
Argon and krypton have similar properties, and they have a complete octet, which means that they do not react with anyone. Hence, option D is correct.
What are inert gases?The phrase "inert gas" is a bit misleading because, in some circumstances, these gases can really be reactive. As a result, these gases are typically referred to as noble gases in the context of chemistry and materials science.
The term "noble" has historically been used in chemistry (and earlier in alchemy) to characterize the resistance of some metals to chemical reaction, and the term "noble gas" denotes the same resistance.
Helium (He)Neon (Ne)Argon (Ar)Krypton (Kr)Xenon (Xe)Radon (Rn)These are the inert gases which are mentioned in the periodic table.

If the white car experiences a change in momentum equal to 105,000 kg*m/s and is in contact with the red car for 5 seconds before coming to rest, how much force, in Newtons, does the white car experience during the collision?
Answer:
21000 N
Explanation:
From the question given above, the following data were obtained:
Change in momentum = 105000 kg.m/s
Time = 5s
Force =?
Force is related to momentum and time according to the following formula:
Force = Change in momentum / time
With the above formula, we can calculate the force the white car experience during the collision. This can be obtained as illustrated below:
Change in momentum = 105000 kg.m/s
Time = 5s
Force =?
Force = Change in momentum / time
Force = 105000 / 5
Force = 21000 N
Thus, the white car experience a force of 21000 N during the collision.

An experimental device imparts a force of magnitude f = 37 lb to the front edge of the rim at a to simulate the effect of a slam dunk. compute the moment of the force f about point o and about point
b. the moments are positive if counterclockwise, negative if clockwise. finally, locate a point c from the base at o to the location on the ground where the force imparts zero moment. the distance d from point o to point c is positive if c is to the right of o, and negative if to the left.
Answer:
a) τ = -518 lb-inch , b) d = 0 inch
Explanation:
a) The moment of a force is given by
τ = F x r
The bold letters indicate vectors, we can solve the magnitude of this expression with
τ = F r sin θ
and the angle by the right hand rule.
In general, the applied force is perpendicular to the rubber and in such a direction that the moment is opposite to the movement, therefore the angle is 270 = -90º and the sin 270 = -1
τ = -F r
To perform a complete calculation, the radius of the rubber is needed, for example for a small car the radius is about 14 inch = 1,167 feet
τ = -37 14
τ = -518 lb-inch
The point o is assumed to be the center of the wheel, the negative sign indicates that the moment is clockwise
b) As the rubber is a circle and the force is perpendicular, the vector product gives an emoticon perpendicular to the rubber, so that this value decreases to zero we must reduce the application point (distance), that is, the distance must be zero.
d = 0 inch

Explanation:
A 125 N box is being raised from the ground floor and accelerating due to a 175 N force. Identify all the forces and find the Net Force.
Answer:
Fn = 50 N
Explanation:
Net Force
The net force is the sum of all the forces acting on an object.
When all the forces act in a single line, the direction of the forces is given by their signs. Positive signs are assumed to be up and left on both axes.
The box being raised by a force has a weight of W=-125 N. The negative sign indicates the weight points down. The accelerating force goes up and its value is F=175 N. The positive sign indicates this force pushes the box up.
The forces acting on the box are:
The weight W=-125 N
The accelerating force F=175 N
The net force is
Fn = W + F = -125N + 175 N
Fn = 50 N
What is the end product of mitosis?
A. Four gametes
B. Two identical nuclei
C. One complete zygote
D. A cell with one set of chromosomes
Answer:
It is B
Explanation:
I did the test
From the given options, the end product of mitosis is Two identical nuclei (option b)
Mitosis is a fundamental cellular process that occurs in somatic (non-reproductive) cells, aiming to create two genetically identical daughter cells from one parent cell. It consists of several stages: prophase, metaphase, anaphase, and telophase.
During prophase, the chromatin (a combination of DNA and proteins) condenses into visible chromosomes, and the nuclear membrane disintegrates. In the subsequent stage, metaphase, the chromosomes align at the cell's equator, ensuring each daughter cell receives an equal number of chromosomes.
Next comes anaphase, where the paired chromosomes are pulled apart and move towards opposite poles of the cell. The final phase, telophase, involves the formation of two separate nuclei around the separated chromosomes.
At the end of mitosis, the single parent cell has divided into two genetically identical daughter cells, each containing a complete set of chromosomes. These daughter cells are fully functional and capable of carrying out their specific tasks within the organism.
So, the correct Answer: B. Two identical nuclei.

2. A driver of a car traveling at 15.0 m/s applies the brakes, causing a
uniform acceleration of -2.0 m/s". How long does it take the car to
accelerate to a final speed of 10.0 m/s?
Answer:
2.5 s
Explanation:
The formula for acceleration is ;
a= v₂-v₁ / t
where ;
a= acceleration = -2 m/s²
v₂= final velocity = 10 m/s
v₁ = initial velocity = 15 m/s
t= time taken for the car to accelerate = ?
Applying the values in the formula as;
a= v₂-v₁ / t
-2 = 10 - 15 / t
-2t = -5
t= -5/ -2
t= 5/2 = 2.5 s

A complex arrangement of pulleys forms what is called the block in a block and tackle. The rope used to lift the pulleys and the load is the tackle. A block and tackle is used to lift a truck engine, which has a weight and output force of nearly 8000 N. The input force required to lift this weight using the block and tackle is 400N. What is the mechanical advantage of the block and tackle?
Answer:
Mechanical advantage = 20
Explanation:
Given:
Output force = 8,000 N
Input force = 400 N
Find:
Mechanical advantage
Computation:
Mechanical advantage = Output force / Input force
Mechanical advantage = 8,000 / 400
Mechanical advantage = 20

A car traveling at 25 m/s speeds up to 30 m/s over a period of 5 seconds. The average acceleration of the car is?
Answer:
a= 1 m/s^2
Explanation:
Average acceleration can be found by dividing the change in velocity by the time.
a= ΔV/t
The change in velocity is the difference of the final velocity and initial velocity.
ΔV= final velocity - initial velocity
The final velocity is 30 m/s and the initial velocity is 25 m/s
ΔV= 30 m/s- 25 m/s
ΔV= 5 m/s
The time is 5 seconds.
Now we know the two values.
ΔV= 5 m/s
t= 5 s
Substitute the values into the formula.
a= 5 m/s / 5 s
Divide.
a= 1 m/s/s
a= 1 m/s^2
The average acceleration of the car is 1 meter per second squared.
Someone please do this ! ASAP I’ll give brainliest!
Answer:
The first law, an object will not change its motion unless a force acts on it.
The second law, the force on an object is equal to its mass times its acceleration.
The third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
