Explanation:
Performing physical activities helps to build a healthy relationship with yourself, in the sense that physical activity promotes health at all levels. Health is a set of physical, mental and social well-being, so physical activity reaches all these levels and increases the quality of life for a person as a whole.
There are several types of physical activities that can be performed and you can choose the one that best fits your preferences and routine. A walk for example can be done in any safe place and at any time and it already helps in improving physical conditioning, in receiving serotonin and endorphins, in reducing blood pressure and protecting the heart and in improving mental health.
So the ideal is for each person to set their own goals in relation to their health and seek to achieve them, either to have a better quality of life, to socialize more with people, to prevent diseases, etc.
Physical exercise helps build relationship by:
This is known to be any physical activities such as walking, running, etc., that is often done so as to keep the body fit.
It is very important when as it helps one to maintain a good balance of mental health. As a person moves their body, there is the release of endorphins that functions to make us feel good and helps handle the effects of stress and anxiety. The more a person exercise, the less mental health cases and more happier relationships.
Note that Values are the drive force of your actions and they push or motivate as you set your life goals. They help to eliminate any obstacle in term of foreign ideas that are against one's value and it keeps one's focus on the goal.

Answer:
+16 J
Explanation:
We can solve the problem by using the 1st law of thermodynamics:
where
is the change of the internal energy of the system
Q is the heat (positive if supplied to the system, negative if dissipated by the system)
W is the work done (positive if done by the system, negative if done by the surroundings on the system)
In this case we have:
Q = -12 J is the heat dissipated by the system
W = -28 J is the work done ON the system
Substituting into the equation, we find the change in internal energy of the system:
The magnitude of each charge is 3.94 x coulombs.
We have a pair of equal charges are separated by 0.75 m and there's a 2500 N force acting on them.
We have to strength of the charge.
According to Coulomb's law, the formula to calculate the force between the two point charges (say q and Q) separated by a some distance (say r) is given by -
F =
According to the question -
Force between two point charges equals to = F = 2500 N
Distance between the point charges = 0.75 m
Let's assume the magnitude of each charge be x, therefore using the coulomb's law, we get -
F =
coulombs
Hence, the magnitude of each charge is 3.94 x coulombs.

Explanation:
Answer:
Once the weighted end of the pendulum is released, it will become active as gravity pulls it downward. Potential energy is converted to kinetic energy, which is the energy exerted by a moving object. An active pendulum has the most kinetic energy at the lowest point of its swing when the weight is moving fastest.
Explanation:
The frequency of the wave with a speed of 330 m/s and 2 meter wavelength is 165 Hz. The time period of the wave is then, 0.006 seconds.
Frequency of a wave is the number of wave cycles per second. Frequency of a wave is the inverse of its time period. It is inversely proportional to the wavelength and directly proportional to the speed.
Hence, ν = c/λ, where c is the speed.
The frequency of a sound wave is called its pitch.
Given that, c = 330 m/s
wavelength λ = 2 meters.
frequency = 330/2 = 165 s⁻¹ or 165 Hz.
The time period of a wave = 1/ frequency.
T = 1/165 = 0.006 s or 6 milliseconds.
Therefore, the frequency of the wave is 165 Hz and time period is 0.006 seconds.

The first thing we must do for this case is to define a frame of reference.
We know that, the frame of reference for this case is Alana.
Therefore, the tennis ball has a speed relative to Alana.
The speed relative to Alana, is the same speed with which Alana throws the tennis ball.
Therefore, the speed of the tennis ball is:
v = 11 Km/h
Answer:
The speed of the tennis ball is:
v = 11 Km/h
Wood has a high heat capacity.
Wood is an insulator.
Wood is an organic substance.
Answer: Wood is an insulator.
Explanation: Conductors are those substances which allow heat and electricity to pass through them.Example: Metals
Insulators are those substances which do not allow heat and electricity to pass through them. Example: wood
Pots and pans should be made of conducting material as the heat needs to be transferred from the burner to the pot and then to the food for cooking.
But the handles should be made from insulators so that they do not become hot and thus we can hold the utensil using the handles without getting burnt.
