1. Calculate the average velocity of the following trip. You walk to Pershing Square 58

Physics
1 answer:
Gre4nikov [31]3 years ago
7 0

Explanation:

Velocity = displacement / time

v = √((58 m)² + (135 m)²) / (12 min × 60 s/min)

v = 0.20 m/s

A system gains 1500 J of heat, while the internal energy of the system increases by 4500 J and the volume decreases by . Assume
Assoli18 [71]

Answer:

Hence the pressure is 3\times 10^5 Pa

Explanation:

Given data

Q=1500 J   system gains heat

ΔV=- 0.010 m^3     there is a decrease in volume

ΔU= 4500 J        internal energy decrease

We know work done is

W= Q- ΔU

=1500-4500= -3000 J

The change in the volume at constant pressure is

ΔV= W/P

there fore P = W/ΔV= -3000/-0.01= 3×10^5

Hence the pressure is 3\times 10^5 Pa

Menciona generaciones de particulas y explique cada una
Readme [11.4K]

ENGLISH:

It distinguishes between the fermions, which are particles of matter, and the bosons, which carry forces. The matter particles include six quarks and six leptons. The six quarks are called the up, down, charm, strange, top and bottom quark. ... All of these matter particles fall into three “generations.”

SPANISH:

Distingue entre los fermiones, que son partículas de materia, y los bosones, que transportan fuerzas. Las partículas de materia incluyen seis quarks y seis leptones. Los seis quarks se denominan quark arriba, abajo, encanto, extraño, superior e inferior. ... Todas estas partículas de materia se dividen en tres "generaciones".

A hard rubber ball on a string is being used as a pendulum. When you first look at the pendulum, the ball is being held to one s
Wittaler [7]

Answer:

<h2>Total thermal energy for all air molecules is 59.54 J</h2>

Explanation:

As we know that the ball comes to rest finally so here we can say that

initial total potential energy of the ball is transferred to the air molecules

So here we have

E_{th} = mgh

E_{th} = (6.2 kg)(9.8 m/s^2)(0.98 m)

So here we have

E_{th} = 59.54 J

So all the gravitational potential energy of the ball will convert into thermal energy of air molecules which is equal to 59.54 J

A football punter accelerates a football from rest to a speed of 15 m/s during the time in which his toe is in contact with the
ioda

Answer:

Force, F = 44 N                

Explanation:

Given that,

Initial speed of the football, u = 0

Final speed, v = 15 m/s

The time of contact of the ball, t = 0.15 s

The mass of football, m = 0.44 kg

We need to find the average force exerted on the ball. It is given by the formula as :

F=ma\\\\F=\dfrac{mv}{t}\\\\F=\dfrac{0.44\times 15}{0.15}\\\\F=44\ N

So, the average force exerted on the ball is 44 N. Hence, this is the required solution.
