Hi there can you guys please help me write 2 paragraphs (4-6 sentences) about in article ("How Many Sets & Reps Should I Do? (Building the Correct Workout Plan)" (Links to an external site.)
Answers
Answer:
well, to create the correct workout plan I think the first day you should do as many reps as you can for each muscle you are targeting. you should also have a day you rest so your body's muscles can build. Monday, Wednesday, Friday are your workout days. Tuesday, Thursday, and Saturday are your rest days. And Sunday can be anything whether it's going to the gym, yoga, or another rest day. But back to the reps, the days you do reps, each day you should be trying to get one more rep/set than the last. If a person is new to working out then they should have a goal of ten rep/sets or something like that, so they don't overwork themselves or tear a muscle. I don't really have any other ideas for a workout plan besides just trying to be consistent and not overworking yourself, but I hope this helps. <3

What would happen to the number of home runs a player could hit if the air was removed from above the field? Use your understanding of Newton's laws to explain.
Answers
Answer:
number of home runs a player would hit would drastically increase
Explanation:
In a hypothetical scenario, if this were to happen the number of home runs a player would hit would drastically increase. When a player hits the ball force is applied to the ball which sends it flying, then the ball meets an opposing force of air resistance and a downward force of gravity which ultimately causes the ball to fall to the ground. This is explained in Newton's first law which states that "objects in motion remain in uniform motion and in a straight line unless they are met by an opposing unbalanced force." Without the force of air resistance, the ball will only be met with a downward force of gravity which would allow it to travel at a much greater distance before hitting the ground, thus resulting in a drastic increase of home runs.

number of home runs a player would hit would drastically increase

Answer:
Vp = 66.67 [mi/h]
Explanation:
To solve this type of problem we must remember that speed is defined as the relationship of space between time.
speed = distance/time
7)
v = speed = 100 [km/h]
distance = 750 [km]
time = distance/speed
time = 750/100
t = 7.5 [h]
8)
v1 = 200/3 = 66.67[mi/h]
v2 = 100/1.5 = 66.67 [mi/h]
Vp = average speed = (v1+v2/2)
Vp = (66.67 + 66.67)/2
Vp = 66.67 [mi/h]

A 2 kg mass moving along a horizontal surface at 10 m/s is acted upon by a 5 N force of
friction. Calculate the net force?
Answers
Answer:
F = 20.61 N
Explanation:
Given that,
Mass of the object, m = 2 kg
It is moving with a speed of 10 m/s
It is acted upon by a 5 N of friction.
The force of gravity acts in downward direction which is given by :
W = mg
W = 2 × 10 = 20 N
5 N of force is acting in horizonal surface.
The net force is given by the resultant of two vectors as follows :
[tex]F=\sqrt{20^2+5^2} \\\\=20.61\ N[/tex]
So, the net force acting on the object is 20.61 N.
The net force acting on the mass is equal to 13.6 Newton.
Given the following data:
Mass = 2 kgSpeed = 10 m/sForce of friction = 5 NWe know that the acceleration due to gravity (g) of an object on planet Earth is equal to 9.8 [tex]m/s^2[/tex].
To calculate the net force:
First of all, we would determine the normal force acting on the mass.
Mathematically, the normal force is given by the formula:
[tex]F_N = mg[/tex]
Where:
m is the mass of an object. g is the acceleration due to gravity.Substituting the given parameters into the formula, we have;
[tex]F_N = 2 \times 9.8[/tex]
Normal force = 19.6 Newton
To find net force:
[tex]Net\;force = 19.6 - 5[/tex]
Net force = 13.6 Newton.
Note: We subtracted because friction opposes the motion of an object and as such acts in opposite direction.

please help i'm a struggling physics student. Thanks so much!
Answers
Answer:
W = 13.26 [J]
Explanation:
Work in physics is defined as the product of force by the distance traveled by the object.
It is important to clarify that the force should be parallel to the direction of movement. In this way, we have to decompose the force into the X component of the movement.
Fx = 16*cos(34) = 13.26 [N]
W = F*d
where:
F = force = 13.26 [N]
d = distance = 1 [m]
W = 13.26*1
W = 13.26 [J]

1 in front of water and 2 in front of oxygen
1 in front of water and 1 in front of oxygen
2 in front of water and 1 in front of oxygen
Answers
Answer:
Answer:
2 in front of water and 1 in front of oxygen
Explanation:
This question is describing balancing a chemical reaction. A balanced chemical reaction has the same number of atoms of each elements on both the reactant and product side. According to the question, the reactants contains 4 atoms of oxygen. The reactants give rise to water (H20) and O2 in the products side.
This reaction is most likely the decomposition of hydrogen peroxide (H2O2) as follows:
H2O2 (l) ----> H2O (l) + O2(g)
Based on the description, H2O2 will be 2H2O2 as it is said to contain four atoms of oxygen. This means that, in order to have a balanced equation, we must place coefficient 2 in front of water and coefficient 1 in front of oxygen. That is;
2H2O2 (l) ----> 2H2O (l) + O2(g)

2 in front of water and 1 in front of oxygen
