why is water further away from the shore colder the further you go?
Answer:
★ For example, cold water has a higher density than warmer water. In Addition, water gets colder with depth because of the coldness, of the salty ocean water which sinks to the bottom of the ocean basins below the less dense water near the surface

How much time does it take for a spinning baseball with an angular speed of 38 rad/s to rotate through 15 degrees
Answer:
the time of motion of the ball is 6.89 ms.
Explanation:
Given;
angular speed, ω = 38 rad/s
angular distance, θ = 15 degrees
Angular distance in radian;
[tex]\theta = 15^0 \times\frac{2\pi \ rad}{360^0} = 0.2618 \ rad[/tex]
Time of motion is calculated as;
[tex]time = \frac{angular \ distance}{angular \ speed} \\\\t= \frac{\theta}{\omega} = \frac{0.2618 \ rad}{38 \ rad/s} \\\\t = 6.89 \ \times 10^{-3} \ s\\\\t = 6.89 \ ms[/tex]
Therefore, the time of motion of the ball is 6.89 ms.

Why is oxygen more chemically reactive than nitrogen?
A. Oxygen needs to gain only 2 electrons to have a full octet, while
nitrogen needs to gain 3.
B. Oxygen needs to gain only 2 electrons to have a full octet, while
nitrogen needs to lose 3.
C. Oxygen needs to lose only 2 electrons to have a full octet, while
nitrogen needs to lose 3.
D. Oxygen needs to lose only 2 electrons to have a full octet, while
nitrogen needs to gain 3.
Oxygen is more chemically reactive than nitrogen because Oxygen needs to gain only 2 electrons to have a full octet, while nitrogen needs to gain 3. The correct option is A.
What are electrons?The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.
Valence electrons are the electrons present in the outermost shell of an atom. They can easily be determined by the number of valence electrons in an atom by looking at the specific group in the periodic table.
The fewer number of electrons in the valance shell, the more reactive is the element.
Oxygen needs to gain only 2 electrons to have a full octet, while nitrogen needs to gain 3.
Thus, Oxygen is more chemically reactive than nitrogen.
Then the correct option is A.

The whale shark the largest of fish and can have the mass of three adult elephants. Suppose that a crane is whale shark into a tank for delivery to an aquariumThe crane must exert an unbalanced force of 2.5 * 10 ^ 4 to lift the shark from rest. If the shark's acceleration equals 1.25 m/s ^ 2 , what is the shark's mass?
Answer:
Mass, m = 20000 kg
Explanation:
The force acting on the shark, [tex]F=2.5\times 10^4\ N[/tex]
Acceleration of the shark, a = 1.25 m/s²
We need to find the mass of the Shark. The force acting on an object is given by :
F = ma
m is the shark's mass
So,
[tex]m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20000\ kg[/tex]
So, the mass of the Shark is 20000 kg.

Ill mark the brainliest pls lmk what answer ty
2800 m
Further explanationGiven
time = 80 s
average velocity = 35 m/s
Required
total distance before it broke down
Solution
Average velocity : total displacement : total time
Can be formulated
avg velocity = Δx : Δt
Input the value :
Δx=avg velocity x Δt
Δx = 35 m/s x 80 s
Δx = 2800 m
In addition, if we are asking for velocity, we must know the starting and ending points (displacement)
But if we calculate the total distance, what is written is the average speed
avg speed = total distance : total time

How old is the sun and since its birth, how has the sun changed?
During its lifespan, what characteristics of the sun will change?
Answer:
(3rd Question about the Black Widow Pulsar)
J1311 is a fast spinning neutron star, which means it emits strong beams of radiation from it's poles.
As the beam of the pulsar sweeps across the surface of the companion star, it heats it up and blows its material outward into space, thus decreasing its mass.

how many electrons does a neutral atom of the element oxygen have?
Answer:
8 electrons
Explanation:
Now you can figure out how many electrons, protons and neutrons Oxygen has: Atomic number (which is always the smaller of the two numbers) is 8. Hence 8 protons. Because the atom is neutral, there are also 8 electrons.

The results suggested that the diameter of the nucleus of a gold
the diameter of the atom.
The diameter of a gold atom is 0.18 nm
Calculate the diameter of a gold nucleus in nm.
Answer:
The diameter of the gold nucleus is 3.0 × 10⁻⁵ nm
Explanation:
The given parameter of the gold atom are;
The diameter of the gold atom = 1/6,000 × The diameter of the atom
The diameter of a gold atom = 0.18 nm
The diameter of the gold nucleus, [tex]d_{Gold -nucleus}[/tex] = 1/6,000 × 0.18 nm = 0.00003 nm
∴ The diameter of the gold nucleus, [tex]d_{Gold -nucleus}[/tex] = 0.00003 nm = 3.0 × 10⁻⁵ nm.
A 400 hp engine in a 1,600 kg car applies maximum force for 2 seconds to accelerate the car onto the
interstate. If the car moves at 8 m/s before accelerating, what is its speed after the 2 seconds of acceleration?
Answer:
I will assume that “maximum force” implies the constant application of power P = 400 hp (international) to accelerating the vehicle. The force will therefore vary with speed as the vehicle accelerates. I will also assume that all engine energy goes into accelerating the vehicle, rather than rotating elements like its wheels.
In this case the 400 hp (equivalent to 298,280 watts) is applied for time t = 2 seconds. Therefore the kinetic energy of the vehicle is increased by:
ΔKE=Pt=(298,280)(2)=596,560 joules.
The initial kinetic energy is:
KEinitial=12mv2
=(0.5)(1600)(82)=51,200 joules.
Therefore final kinetic energy is:
KEfinal=KEinitial+ΔKE
=51,200+596,560
=647,760 joules
Therefore final vehicle velocity can be found:
KEfinal=12mv2
v=2KEfinalm−−−−−−−−√
=(2)(647,760)1600−−−−−−−−−−−√
= 28.455 m/s
