In which state of matter do the particles spread apart and fill all the space available to them?a. crystal
b. liquid
c. gas
d. solid

Answers

Answer 1
Answer: The correct answer is c) gas.

In gases, in fact, particles are not bound together (and the intermolecular forces between them are negligible) and they are completely free to move. For this reason, when a gas is put in a container, the particles of the gas will move in every possible direction, filling all the space available in the container (for this reason, we also say that gases have no fixed shape).

A concave mirror has a radius of curvature of 10 cm. Find the location an height of the image if the distance of the object is 8cm and the height of the object is 1.5 cm, using a scaled ray diagram

Answers

R=10
F=R/2
F=10/2=5
F=-5(CONCAVE MIRROR)
U=-8(CONCAVE MIRROR)
HEIGHT OF OBJECT=1.5
V=?
HEIGHT OF IMAGE=?
I/F=1/U+1/V
-I/5=-1/8-1/V
-1/V=-1/5+1/8
-1/V=-8+5/40
-1/V=-3/40
1/V=3/40
V=40/3

HEIGHT OF IMAGE/HEIGHT OF OBJECT =-V/U

Two balls, each with a mass of 0.844 kg,exert a gravitational force of 8.45 × 10−11 Non each other.How far apart are the balls? The value of the universal gravitational constant is 6.673 × 10−11 N m2/kg2.

Answers

The Universal Gravitation law is F=GMm/d^2
So: 8.45x10^-11=6,673x10^-11x0,844x0,844/d^2

5,000 joules of thermal energy were applied to 1-kg aluminum bar. What was the temperature increase?

Answers

Answer:

ΔT = 4.9°C

Explanation:

The thermal energy of the bar can be given as follows:

Thermal Energy = mCΔT

where,

m = mass of bar = 1 kg

C = specific heat capacity of aluminum = 1020 J/kg.°C

ΔT = Change in Temperature = ?

Therefore,

5000 J = (1 kg)(1020 J/kg.°C)ΔT

ΔT = (5000 J)/(1020 J/°C)

ΔT = 4.9°C

The potential energy of a catapult was completely converted into kinetic energy by releasing a small stone with a mass of 20 grams. The velocity of the stone when it reached the target was 15.0 meters/second. What was the value of the kinetic energy of the stone when it reached the target?

Answers

Answer: 2.25 J

Explanation: Kinetic energy is the energy possessed by an object by virtue of its motion.

K.E=(1)/(2)* mv^2

m= mass of object= 20 g = 0.02 kg     (1 kg= 1000 g)

v= velocity of object= 15 m/s

K.E=(1)/(2)* 0.02* 15^2=2.25kgm^2s^(-2)=2.25J

(1J=1kgm^2s^(-2))

1,000 grams = 1 kilogram
20 grams = 0.02 kilogram

Kinetic energy = (1/2) (mass) x (speed)²

                           (1/2) (0.02) x (15)² =

                                 (0.01)  x  (225)  =  2.25 joules
