What is physical activity?Anybody movement requiring energy expenditure that is produced by skeletal muscles is defined as physical activity. Physical exercise encompasses all forms of movement,
Whether it is done for fun, to go to and from locations, or as part of one's job. Physical activity, both moderate and strenuous, is beneficial to one's health.
Physical activity is good for your heart, body, and mind. Physical exercise aids in the prevention and treatment of noncommunicable illnesses including heart disease, cancer, and diabetes.
Depression and anxiety symptoms are alleviated by physical activity. Physical activity improves one's ability to think, learn, and judge.

What is the speed of a snail moving at a rate of 3 inches per minute in [m/s]? Recall that 1 [m] = 39 [in]. Round to the nearest ten thousandth (4 places after the decimal).
Answer:
0.0013 m/s
Explanation:
Speed in inches per minute = 3 inches per minute
Speed in m/s =?
Next, we shall convert 3 inches per minute (3 in/min) to metre per minute.(m/min)
39 in/min = 1 m/min
Therefore,
3 in/min = 3 in/min × 1 m/min / 39 in/min
3 in/min = 1/13 m/min
Finally, we shall convert 1/13 m/min to m/s. This can be obtained as follow:
1 m/min = 1/60 m/s
Therefore,
1/13 m/min = 1/13 m/min × 1/60 m/s / 1 m/min
1/13 m/min = 1/780 m/s
1/13 m/min = 0.0013 m/s
Thus, 3 in/min is equivalent to 0.0013 m/s.
Therefore the speed of the snail in m/s is 0.0013 m/s

Find the magnitude and direction of the net gravitational force on mass A due to masses B and
C in the figure. Each mass is 2 kg.
a. 2.8x10^-8N, to the right
b. 2.54x10^-8N, to the right
c. 3.4x10^-8N, to the left
d. 3.4x10^-8N, to the right
Answer is A 2.8 x 10^-8 N, to the right
The net gravitational force on mass A due to masses B and C is required.
The correct option is a. [tex]2.8\times 10^{-8}\ \text{N}[/tex] to the right.
G = Gravitational constant = [tex]6.674\times 10^{-11}\ \text{Nm}^2/\text{kg}^2[/tex]
[tex]r_{AB}[/tex] = Distance between A and B = 0.4+0.1 = 0.5 m
[tex]r_{AC}[/tex] = Distance between A and C = 0.1 m
[tex]m_A=m_B=m_c[/tex] = Mass of each particle = 2 kg
The required force is
[tex]F_A=F_{AB}+F_{AC}\\ =\dfrac{Gm_Am_B}{r_{AB}^2}+\dfrac{Gm_Am_C}{r_{AC}^2}\\ =Gm^2\left(\dfrac{1}{r_{AB}^2}+\dfrac{1}{r_{AC}^2}\right)\\ =6.674\times 10^{-11}\times 2^2\left(\dfrac{1}{0.5^2}+\dfrac{1}{0.1^2}\right)\\ =2.8\times 10^{-8}\ \text{N}[/tex]
The magnitude of force will be [tex]2.8\times 10^{-8}\ \text{N}[/tex]
The direction will be towards the right since C is closer to A.

A hockey puck sliding on a frozen lake comes
to rest after traveling 176 m.
If its initial velocity is 2.3 m/s, what is its
acceleration
Given parameters:
Distance traveled = 176m
Initial velocity = 2.3m/s
Unknown:
Acceleration = ?
Solution:
Acceleration is the change in velocity with time. To solve this problem, we apply one of the motion equations;
V² = U² + 2as
where V is the final velocity
U is the initial velocity
a is the acceleration
s is the distance
final velocity is 0;
0² = 2.3² + 2 x a x 176
-5.29 = 352a
a = - [tex]\frac{5.29}{352}[/tex] = - 0.015m/s²

Light travels slower in oil than in air. If a light wave moves through the oil at a speed of 2 x 108 m/s and the wavelength of this light wave is 2 x 10-3 m, what is the frequency of this wave?
1 x 105 Hz
4 x 10-24 Hz
4 x 105 Hz
1 x 1011 Hz
The frequency of this wave will be 1 × 10¹¹ Hz. Option d is correct. Frequency is the inverse of the time period.
What is the frequency?Frequency is defined as the number of repetitions of a wave occurring waves in 1 second.
The given data in the problem is;
v is the speed of light = 2 x 10⁸ m/s
[tex]\lambda[/tex] is the wavelength = 2 x 10⁻³ m,
f is the frequency of the wave is to be found;
Frequency is given by the formula as,
[tex]\rm v = \lambda \times f \\\\\ \rm f = \frac{v}{\lambda} \\\\ \rm f = \frac{2 \times 10^8}{2 \times 10^-3} \\\\ \rm f = 1 \times 10^{11} \ Hz[/tex]

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 25 N acts on a certain object, the acceleration of the object is 5 /ms2. If the force is changed to 40 N, what will be the acceleration of the object?
Answer:
3
Explanation:
the change in velocity is 15, and if I'm right which I may not be you divide your change in velocity by your speed being 5 and get 3. i googled the equation to find acceleration and found a = v/t. this could be absolutely wrong but I hope it helps

Which best describes the definition for the atomic mass of an element?
It is a weighted average of the masses of an element’s isotopes.
It is a ratio based on the mass of the carbon-12 atom.
It is the sum of the protons and neutrons in one atom of the element.
It is twice the number of protons in one atom of the element.
Answer:
It is a weighted average of the masses of an element’s isotopes.
Explanation:
The best definition of the atom mass of an element is that it is a weighted average of the masses of an element's isotopes.
Isotopes of an element have the same electronic configuration but differ in only their masses. The atomic mass of an element can be derived from the geonormal abundances of this isotopes. It is the average of all the isotopes of an element.Atomic mass = ∑m[tex]_{i}[/tex] a[tex]_{i}[/tex]
where m[tex]_{i}[/tex] is the mass of the isotope i
a[tex]_{i}[/tex] is the abundance of the isotope i

1. Explain a stretching routine for your work environment. As you consider your routine, keep in mind the specific individuals within your work environment who will be using this plan. How will you account for differences in sizes, ages, and cultures?
Answer:
Explanation:
A stretching routine should target most of the main muscles in the body and at least one stretching exercise per section of the body. Also in a work environment since individual's sizes, ages, and cultures vary you should design a routine that is for beginners and very easy and effective. Regardless, each individual should be able to move at their own pace and push as far as they are physically able. One such routine would be the one in the attached picture below which targets all major areas, is easy and effective. It starts at the neck muscles and works its way down the arms, back, and legs.
