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.
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.
Answer:
number of home runs a player would hit would drastically increase
Explanation:
What task requires the most work, lifting a 12-kg sack 2 meters or lifting a 25-kg sack 1 meter?
a.) the 12-kg sack
b.) the 25-kg sack
c.) Both require the same amount of work.
d.) Impossible to determine without knowing the contents of the sack
Please answer ASAP!! Thank you!!
Multiply the masses by the respective distances:
(12 kg) (2 m) = 24 J
(25 kg) (1 m) = 25 J
so the heavier bag takes more work to lift, and (b) is the answer.
(d) is technically correct if the sacks are carrying different contents whose masses are not equal, but since we don't know what's inside each sack, assume 12 kg and 25 kg are the masses of each sack *and* their contents.
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.)
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
Explanation:
You'll have to add on your own ideas to make it longer and add a bit more detail of course but I think you'll do well.

A block of mass 3 kg is pushed 1 m along a frictionless horizontal table by a constant 16 N force directed 34◦ below the horizontal. Determine the work done by the applied force. Answer in units of J.
please help i'm a struggling physics student. Thanks so much!
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]

Explanation:
You are an astronomer on planet tirth, which orbits a distant star. it has recently been accepted that tirth is spherical in shape, though no one knows its size. one day, you learn that on the equinox your sun is directly overhead in the city of tyene, located 750 kilometers due north of you. on the equinox, you go outside in alectown and observe that the altitude of your sun is 87.0 ∘.
Answer:
The circumference of planet tirth is [tex]C = 90000 \ km[/tex]
Explanation:
From the question we are told that
The distance of tyene from the observer is [tex]d = 750 \ km[/tex]
The altitude of the sun from the equinox is [tex]\theta_s = 87.0^o[/tex]
Generally given that on the equinox your sun is directly overhead in the city of tyene , then the altitude of the tyene from the equinox is [tex]\theta_e = 90 ^o[/tex]
Generally the angular distance between tyene and the sun as observed from the equinox is mathematically represented as
[tex]\theta _d = \theta_e - \theta_s[/tex]
=> [tex]\theta _d = 90 -87[/tex]
=> [tex]\theta _d =3^o[/tex]
Generally the ratio of [tex]\theta _d =3^o[/tex] to [tex]360^o[/tex] which is the total angle in a circle is equal to the ratio of [tex]d = 750 \ km[/tex] to the circumference of the planet
So
[tex]\frac{\theta_d}{360} = \frac{750}{C}[/tex]
=> [tex]\frac{3}{360} = \frac{750}{C}[/tex]
=> [tex]C = 90000 \ km[/tex]

The amount of oxygen in the reactants is 4 atoms. In the products, the oxygen is distributed to water (H2O) and O2 gas. Which coefficients would be placed in front of water and oxygen?
2 in front of water and 2 in front of oxygen
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
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)
Explanation:
Answer:
2 in front of water and 1 in front of oxygen

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?
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.

how does an air pump work
Answer:
When the piston is pulled up, air gets sucked into the pump through the inlet. The pump chamber depressurizes as it fills with air. When the piston is forced down, the air becomes compressed and closes the inlet. Then the air flows out from the outlet
