The centripetal force acting on a 1.5 kg mass moving in a circular path is 27N
A centripetal force is a net force acting on an object in order to maintain the object's movement in a circular motion.
According to Newton's first law, it states an object will continue to proceed its movement in a straight line unless acted upon by an external force.
The centripetal force is the external force at work here and It's the net force that propels the object in a circular motion.
Using the formula for calculating centripetal force:
[tex]\mathbf{F_c = mass (m) \times acceleration (a)}[/tex]
[tex]\mathbf{F_c = 1.5 \ kg \times18 \ m/s^2}[/tex]
[tex]\mathbf{F_c = 27 \ N}[/tex]

How does the distance between the planet and the Sun affect its period?
Answer:
The closer a planet is to the sun, the shorter its period of revolution. The farther away a planet is from the sun, the longer its period of revolution.
Explanation:
i hope that helps, have a great day.
Answer:
The closer a planet is to the sun, the shorter its period of revolution. The farther away a planet is from the sun, the longer its period of revolution. so it depends on how close and how far it is to have a different time period. so if the if it is close then the period of revolution will be shorter because they need more space to have a longer period. if it is spaced out then it will have a longer period because they do have space.

During a test, a solution placed on a sheet
of metal creates bubbles. This solution is
most likely
A. Acidic
B. Neutral
C. Basic
Answer:
B. Acidic
Explanation:
Neutral an Basic solutions wouldn't create any reaction
If during a test, a solution placed on a sheet of metal creates bubbles, we can conclude that this solution is most likely Acidic.
Reaction of metals with acidAcid reacts vigorously with metal, displacing hydrogen gas in the process and this process creates bubbles of gases trying to escape from the solution.
Metals do not react basic and neutral solutions.
If during a test, a solution placed on a sheet of metal creates bubbles, we can conclude that this solution is most likely Acidic.

How much physical activity should an adult have each week?
A.
60 minutes per day, 7 days a week
B.
30 minutes per day, 7 days a week
C.
60 minutes per day, 5 days a week
D.
30 minutes per day, 5 days a week
Please select the best answer from the choices provided.
A
B
C
D
The physical activity should an adult have each week is "60 minutes per day, 5 days a week". The correct answer is option C.
What is WHO?WHO stands for the World Health Organization. It is a specialized agency of the United Nations responsible for international public health. The WHO is headquartered in Geneva, Switzerland, and works in partnership with national governments and other organizations to promote health, keep the world safe, and serve the vulnerable. The organization's primary objective is to ensure that people can enjoy the highest possible level of health, regardless of their race, religion, or socioeconomic status. The WHO's work includes providing leadership on matters critical to health, setting norms and standards, promoting health research and evidence-based practice, and providing technical support to countries.
Here in the Question,
Option A, "60 minutes per day, 7 days a week," and option B, "30 minutes per day, 7 days a week," both suggest that physical activity should be performed every day of the week. While daily physical activity is beneficial for overall health and well-being, the WHO recommendation allows for two days of rest or lighter physical activity per week, which can help prevent injury and allow for recovery.
Option D, "30 minutes per day, 5 days a week," suggests a lower amount of physical activity than the WHO recommendation. While 30 minutes of moderate-intensity aerobic physical activity per day can provide some health benefits, it may not be enough to achieve significant improvements in cardiovascular health, muscular strength, and flexibility.
Therefore, Option C, "60 minutes per day, 5 days a week," is the correct answer as it aligns with the WHO recommendation for adults to engage in at least 150 minutes of moderate-intensity aerobic physical activity per week.

A negative charge is paced in an electric field that points west. What direction is the force on the negative particle?
Answer:
A positive charge placed in an electric field will tend to move in the direction of the electric field lines and a negative charge will tend to move opposite to the direction of the electric field lines.
One way to remember this is that there is one velocity, and so the thumb represents it. There are many field lines, and so the fingers represent them. The force is in the direction you would push with your palm. The force on a negative charge is in exactly the opposite direction to that on a positive charge.
Explanation:
Answer:
The force of the negative particle direction is East.

B. 0.53m/s
C. 0.71 m/s
D. 0.07m/s
Hi there!
For projectile motion, the horizontal and vertical components are SEPARATE.
We can use the kinematic equation to solve:
dₓ = vₓt
We can rearrange to solve for vₓ:
dₓ/t = vₓ
0.31/0.22 = vₓ
vₓ = 1.4 m/s ⇒ A

A child, m = 25. 0 kg, swings from a rope, l = 9. 43 m, which hangs above water, d = 1. 9 m, when vertical. The child is h = 4. 8 m above the water when she begins to swing.
The velocity at the bottom of the swing is [tex]\mathbf{v= \sqrt{2gh -2gd}}[/tex]. The time it took the child to reach the river is 0.62 seconds.
The objective of this question is to determine:
The expression for the velocity of the child at the bottom of the swing.Suppose the child lets go at the bottom of the swing, how long does she take to reach the river at t seconds.At the bottom of the swing, there is an equal change in both the Kinetic energy as well as the potential energy and the expression can be computed as:
[tex]\mathbf{\dfrac{1}{2}mv^2 = mg (h -d)}[/tex]
[tex]\mathbf{\dfrac{v^2}{2}= g (h -d)}[/tex]
[tex]\mathbf{v^2= 2gh -2gd}[/tex]
[tex]\mathbf{v= \sqrt{2gh -2gd}}[/tex]
According to the second equation of motion;
[tex]\mathbf{S = ut +\dfrac{1}{2}at^2}[/tex]
where;
distance s = d = 1.9 macceleration due to gravity = 9.8 m/s²initial velocity (u) = 0∴
[tex]\mathbf{1.9 = 0(t) +\dfrac{1}{2}(9.8) t^2}[/tex]
[tex]\mathbf{1.9 = \dfrac{1}{2}(9.8) t^2}[/tex]
[tex]\mathbf{t^2 =\dfrac{1.9\times 2}{9.8} }}[/tex]
[tex]\mathbf{t = \sqrt{\dfrac{1.9\times2}{9.8}}}[/tex]
[tex]\mathbf{t =0.62 \ s}[/tex]
Therefore, we can conclude that the velocity at the bottom of the swing is [tex]\mathbf{v= \sqrt{2gh -2gd}}[/tex]. The time it took the child to reach the river is 0.62 seconds.
