Summarize the Venn diagram.

Physics
1 answer:
Elena L [17]3 years ago
5 0

Answer:

If this is a multiple choice question, then the answer is D.

Explanation:

Compounds are composed of atoms, which are composed of subatomic particles and consist of matter. Since they are composed of atoms rather than vice-versa, compounds cannot be found inside atoms and are not the most basic form of matter (ruling out A and C). A pure substance contains atoms, which are each composed of subatomic particles. Therefore, a pure substance must have atoms if it contains subatomic particles (ruling out B). The only answer left is D.

estimate the force that a cyclist travelling at 6m/s needs to apply to the brakes to bring the bicycle to a stop in a distance o
RSB [31]

v1 = 6m/s

v2 = 0

∆v = v1 - v2 = 6m\s

s = t * v = 15m

t = s\v1 = 15(m) \ 6(m\s) = 2.5s

a = ∆v\t = 6(m\s) \ 2.5s = 2.4m\s2

a = F\m = 2.4m\s2

F = a * m = 2.4m\s2 * ?kg

I can't tell you this because I don't know the mass of this cyclist

How do I solve this question
babunello [35]

Newton would not agree with that explanation, and he would tell my brother to go to his room.  Then Newton would turn to me and explain:

Once the soccer ball is in motion, it will continue moving in a straight line with constant speed, until external forces change its motion. (Newton's #1 Law of Motion).

There are external forces on the soccer ball after the kick:  gravity, air resistance, and scraping through grass.

Gravity has no effect on its horizontal motion.  But air resistance and scraping through grass are both friction ... they both rob kinetic energy from the ball.  Once the kinetic energy of the ball is all gone, it doesn't move any more.  An observer looking at the ball and measuring its motion would write in his notebook "The ball has stopped." .

A partition divides an insulated tank into two parts. One part of the tank contains 2.5 kg of compressed liquid water at 60°C an
jeka94

Answer:

V=0.972m^2

Explanation:

the energy balance is :

E_{in} -E_{out} =ΔE_{system}

0=ΔU=mm(u_{2} -u_1)

u_1=u_2

the properties of water are from table

P_1=500 kpa\\T_1=60 degree C\\v_1=v_f_{-->60} =251.6 Kj/Kg

verified if we get a quantity between 0 and 1

P_2=10 kpa\\u_2=u_1

we have,

v_f=0.001\\v=14.670 m^3/kg\\u_f=191.79\\v_{fg}=2245.4 Kj/Kg\\

therefore,

x_2=\frac{u_2-u_f}{u_{fg} }

we replace the values in this equation:

x_2=\frac{251.6-191.79}{2245.4}\\ x_2=0.026

so,

T_2=T_{sat--10kpa} =45.81\\v_2=v_f-x_2v_{fg}

we replace the values in this equation:

v_2=0.38886m^3/kg

we have,

V=mv_2

we replace the values in this equation:

V=0.972m^2

An electron moving at in a 1. 25-t magnetic field experiences a magnetic force of. what angle does the velocity of the electron
igomit [66]

The angle the velocity of the electron make with the magnetic field is     sin(∅) = 90° answer.

  The equation F = qv X B may be damaged down into two elements, the significance and the path. The importance is given by F = qv B sin(∅),

Magnetic field =  1. 25-tesla

                  F = qv B sin(∅)

               = sin(∅) = F/qv B

                 sin(∅) =  qv X B/qv B

                   sin(∅) = 90° answer.

The most importance of the magnetic pressure appearing at the electron whilst its velocity v is perpendicular to B i.e magnetic discipline. The route of the force acting on the electron is the course the palm of the left hand faces. The path of the magnetic area, the direction of the transferring rate, and the route of the pressure on the particle are all perpendicular to each other.
