Select all that apply. Which statements are supported by the second law of thermodynamics? The usable energy in the universe is decreasing. The usable energy in the universe is increasing. The energy of the universe is being destroyed. The entropy of the universe is increasing.

Answers

The statements supported are:

- The usable energy in the universe is decreasing.
- The entropy of the universe is increasing.

The second law of Thermodynamics establishes that in each energy convertion, in an isolate system, a part of energy is converted into heat (unusable energy) and the entropy of the system increase.

Answer:

a and d

Explanation:

What does it depend on

Answers

Electric force varies directly with the magnitude of each charge, and inversely with the distance between the charges.

but for short....

electrical force depends on the charge and distance

A toy cannon uses a spring to project a 5.24-g soft rubber ball. The spring is originally compressed by 5.01 cm and has a force constant of 8.08 N/m. When the cannon is fired, the ball moves 15.8 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.031 0 N on the ball.With what speed does the projectile leave the barrel of the cannon?

Answers

Answer:

Speed will be equal to 1.40 m/sec

Explanation:

Mass of the rubber ball m = 5.24 kg = 0.00524 kg

Spring is compressed by 5.01 cm

So x = 5.01 cm = 0.0501 m

Spring constant k = 8.08 N/m

Frictional force f = 0.031 N

Distance moved by ball d = 15.8 cm = 0.158 m

Energy gained by spring

$KE=(1)/(2)kx^2=(1)/(2)* 8.08* 0.0501^2=0.0101J$

Energy lost due to friction

$W=Fd=0.031* 0.158=0.0048J$

So remained energy to move the ball = 0.0101 - 0.0048 = 0.0052 J

This energy will be kinetic energy

$(1)/(2)mv^2=0.0052$

$(1)/(2)* 0.00524* v^2=0.0052$

v = 1.40 m/sec

A car initially at rest, accelerates at a constant rate of 4.0 m/s for 6s. How fast will the car be traveling at 6s

Answers

it will be traveling exactly 24 miles per hour

Final answer:

The final velocity of the car can be found using the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time. Plugging in the given values, we find that the car will be traveling at 24 m/s at 6 seconds.

Explanation:

To find the final velocity of a car accelerating at a constant rate, we can use the equation:
v = u + at

Where:
v is the final velocity, u is the initial velocity (which is zero in this case), a is the acceleration (4.0 m/s²), and t is the time (6 seconds).

Plugging in the values, we get:
v = 0 + (4.0 m/s²)(6s) = 24 m/s

Therefore, the car will be traveling at 24 m/s at 6 seconds.

How much force is needed to accelerate a 68 kilogram-skier at a rate of 1.2 m/sec^2?

Answers

Answer: Force = 81.6 N

Explanation:
According to Newton's Second law:
F = ma --- (1)

Where F = Force = ?
m = Mass = 68 kg
a = Acceleration = 1.2 m/s^2

Plug in the values in (1):
(1) => F = 68 * 1.2
F = 81.6 N (The force needed to accelerate the skier at a rate of 1.2 m/s^2)

Answer:

The force needed to accelerate a 68 kilogram-skier at a rate of 1.2ms2 is 81.6 Net forces
