Answer:
No
Explanation:
A planet's orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.

What is the acceleration of an object that goes from 45m/s to 10 m/s in 5 seconds?
Answer:
[tex]\boxed {\boxed {\sf a= -7 \ m/s^2}}[/tex]
Explanation:
Acceleration is the change in velocity over time.
[tex]a= \frac {v_f-v_i}{t}[/tex]
The object accelerates from 45 meters per second to 10 meters per second in 5 seconds. Therefore,
[tex]v_f=10 \ m/s \\v_i= 45 \ m/s \\t= 5 \ s[/tex]
Substitute the values into the formula.
[tex]a= \frac{ 10 \ m/s - 45 \ m/s}{5 \ s}[/tex]
Solve the numerator.
[tex]a= \frac { -35 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= -7 \ m/s/s[/tex]
[tex]a= -7 \ m/s^2[/tex]
The acceleration of the object is -7 meters per square second. The acceleration is negative because the object's velocity decreases and the object slows down.
A boat trip travels are 15 miles in the direction of 45° east of north for an hour the boat then turn and travels at 18 m/s in a direction 5° north of East for an hour
Answer:
Hello your question is incomplete below is the missing piece
What is the magnitude of the boat’s resultant velocity? Round your answer to the nearest whole number.
answer : 25.73 m/s
Explanation:
Given
V1 = 15 miles/hour = 6.71 m/s [ 45° EN ]
V2 = 18 m/s [ 5° NE ]
Calculate the resultant velocity
Vr = 6.71 m/s[45°] + 18m/s[5°].
Vr = ( 6.71 *Cos45° + 6.71 *sin45°) + ( 18 *Cos5° + 18*sin5° )
Vr = ( 4.74 + 4.74 i )+ ( 17.93 + 1.57i) = 22.67 + 12.18i.
Therefore the magnitude
= [tex]\sqrt{22.67^2 + 12.18^2}[/tex] = 25.73 m/s

Which of the following best describes how the spinal cord and the brain work together?
A
Messages travel to and from the brain to other parts of the body through the spinal cord.
B
The spinal cord controls the body’s movement, and the brain controls coordination.
C
The spinal cord sends messages to the brain, telling it what functions to perform.
D
The spinal cord is a bone in the back that supports your skull, which houses the brain.
Messages travel to and from the brain to other parts of the body through the spinal cord. Thus, brain and spinal cord works together and option A is the correct answer.
How does the brain and spinal cord work together?The spinal nerves connect the brain to the nerves in the major part of the body. Other nerves connect the brain to the eyes, ears, and other parts of the head directly. This network of nerves relays messages between the brain and the rest of the body.
The brain and spinal cord comprise the central nervous system. The brain is in charge of how we think, learn, move, and feel. The spinal cord relays messages from the brain to the nerves that run throughout the body.
Therefore, brain and spinal cord works together as messages travel to and from the brain to other parts of the body through the spinal cord.

What is the gravitational force between two 15-kg packages that are 0.35 cm apart?
Answer:
u wanna play some blox?
Explanation:
Richard Julius once made a model plane that could travel a max speed of 110 m/s. Suppose the plane was held in a circular path by a control line. Suppose the plane ran out of gas while moving at its maximum speed and Richard Julius pulled the line in to bring the plane home while it continued in a circular path. If the line's initial length is 120 m and Richard Julius shortened the line by 0.80 m every second, what was the plane's speed after 33.0 s?
Answer:
85.8 m/s
Explanation:
We know that the length of the circular path, L the plane travels is
L = rθ where r = radius of path and θ = angle covered
Now,its speed , v = dL/dt = drθ/dt = rdθ/dt + θdr/dt
where dθ/dt = ω = angular speed = v'/r where v' = maximum speed of plane and r = radius of circular path
Now, from θ = θ₀ + ωt where θ₀ = 0 rad, ω = angular speed and t = time,
θ = θ₀ + ωt = 0 + ωt = ωt
So, v = rdθ/dt + θdr/dt
v = rω + ωtdr/dt
v = (r + tdr/dt)ω
v = (r + tdr/dt)v'/r
v = v' + tv'/r(dr/dt)
v = v'[1 + t(dr/dt)/r]
Given that v' = 110 m/s, t = 33.0s, r = 120 m and dr/dt = rate at which line is shortened = -0.80 m/s (negative since it is decreasing)
So, v = 110 m/s[1 + 33.0 s(-0.80 m/s)/120 m]
v = 110 m/s[1 + 11.0 s(-0.80 m/s)/40 m]
v = 110 m/s[1 + 11.0 s(-0.02/s)]
v = 110 m/s[1 - 0.22]
v = 110 m/s(0.78)
v = 85.8 m/s

how might have atomic numbers of elements indicate that newly discovered elements would have to have very high atomic numbers
Answer:
The scientists who discovered them will start things off by proposing a name. But it will be down to the International Union of Pure and Applied Chemistry (IUPAC) to approve it.
I'm slow...
Newly discovered elements often occur at the bottom of the groups where they occur in the periodic table hence they must have very high atomic numbers.
In the periodic table, the properties of elements are arranged in increasing order of their atomic numbers according to the modern periodic law. As you move down the group, the atomic numbers of elements continue to increase.
Since the properties of elements are periodic, newly discovered elements often occur at the bottom of the group hence they have very high atomic numbers.

Hi people; there's a question that has been so confusing for me and a friend of mine.
0°C + 0°C = 64°F
Is this correct or wrong?
Answer:
The correct answer is: 0°C + 0°C = 32°F
Explanation:
We need to remember the conversion equation from Celsius to Fahrenheit:
[tex]y^{\circ}F=(x^{\circ}C * \frac{9}{5})+32[/tex]
In our case x = 0, then y will be:
[tex](0^{\circ}C * \frac{9}{5})+32=32[/tex]
[tex]y=32^{\circ}F[/tex]
Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.
Then, knowing that 0°C = 32°F we can conclude that:
[tex]0^{\circ}C+0^{\circ}C=32^{\circ}F[/tex]

Which of the following would have the most momentum?
A. A train traveling 60 miles per hour.
B. A motorcycle traveling 60 miles per hour.
C. A car traveling at 60 miles per hour.
D. A basketball traveling 60 miles per hour.
Answer:
A. A train traveling 60 miles per hour.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
[tex] Momentum = mass * velocity [/tex]
This ultimately implies that, the mass of an object or body is directly proportional to its momentum. Thus, the higher the mass of an object or body, the greater would be its momentum and vice-versa.
Hence, a train traveling 60 miles per hour would have the most momentum because it has the greatest mass among the other objects (options).
